Fuligo sp. L. Dog vomit slime mold, Flowers of Tan, DE: Lohblte, HexenbutterSlo.: reslov cvetDat.: Oct. 19. 2015 - 13:55; about 5 days after previous picturesCode: Bot_920/2015_DSC9418All observations: Lat.: 46.36005 Long.: 13.70239Habitat: edge of former pasture; partly overgrown with Picea abies, Ostrya carpinifolia, Fagus sylvatica; slightly inclined mountain slope, southwest aspect, locally almost flat terrain, shallow, stony, calcareous ground; open, mostly sunny place; exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7 - 9 deg C, elevation 595 m (1.950 feet), alpine phytogeographical region. Temperatures from Oct. 11. to Oct. 19. were between 1 to 12 deg C, from Oct. 13. to Oct. 19. there were periods of very heavy rains. Substratum: on bark of a piece of cut down Picea abies trunk deposited on a pile of cut down Picea abies wood and branches; wood in its initial decomposition phase, mostly still in bark.Place: Lower Trenta valley, between villages Soa and Trenta, right bank of river Soa; near 'Na Melu' place somewhat south of Trenta 2b cottage; East Julian Alps, Posoje, Slovenia EC.Comments: This Myxomicete almost certainly belongs to genus Fuligo. The first measurement of its spores made on live material distinguished it from the most common species in this genus Fuligo septica. Fuligo septica has smaller spores, from 6 to 9 microns in diameter, while most of other species have spores larger than 10 microns in diameter. Also colors of either aethalium (fruiting body formed from all or most of the plasmodium), or of plasmodium (acellular, multinucleate mass of protoplasm, which crawls around, feeds and grows before it forms aethalium), or of inner lime (structure within spore mass of mature aethalium) of this observation fit perfectly to none of the five varieties of Fuligo septica described in Ref.:3 (namely: F.s. var. septica, F.s. var. flava, F.s. var. candida, F.s. var. rosea and F.s. var. rufa). Using the key of the genus Fuligo given in Ref.: 1 one comes straight to Fuligo intermedia Macbr., syn.: Fuligo cinerea var. ecorticata Lister. The measured average spore diameter and spore surface fit best, but not perfect, to this species (pertains to the first measurement of spores). But there are important differences from the descriptions of this species in the literature. For example, cortex (a more or less thick outer layer of an aethalium) is not thin as it should be. Hypothallus (a thin layer between the substrate and fruiting body) was membranous and of several layers (as it should be according to Ref.:1) but it was only locally white. Dominant colors were yellow and even red. According to literature the color of aethalium should be dirty white, pale gray or brownish. This was so only on a rather limited part of aethalium (see pictures 30-32 upper part of the aethalium). Aethalium was mostly black with partly deep reddish tint. The dried sample of the find has been analyzed at the Slovenian Forestry Institute by Mrs. Sanja Behri. Spores have been measured twice (on two sets of equipment). Significantly smaller average dimension (8.5-8.7 m and 8.8 m; n > 20) found. This fits well to Fuligo septica. However, the other observed discrepancies from this species remain. A most probable but unverified assumption is that very bad weather with low temperatures during the development of the aethalium caused unusual properties. The quite significant differences in the results of spore dimensions of all three measurements could be the consequence of an uneven development of spore mass in different parts of aethalium, which were analyzed. But this is only an assumption. Because of that a reliable determination of the find remains open.Spores minutely warted. Dimensions: 9.6 [10.2 ; 10.5] 11.1 x 8.4 [9.1 ; 9.4] 10.1 microns; Q = 1 [1.1] 1.2; N = 30; C = 95%; Me = 10.4 x 9.2 microns; Qe = 1.1.

Fuligo septica var. flava (Pers.) Morgan, syn.: Mucor septicus L., Aethalium flavum (Pers) LinkFlowers of Tan, DE: Gelbe LohblteSlo.: reslov cvet, rumeni razliekDat.: Sept. 05. 2014Lat.: 46.35965 Long.: 13.70116Code: Bot_832/2014_DSC3621Habitat: mixed wood, Fagus sylvatica and Picea abies dominant, moderately southeast inclined mountain slope, shallow, skeletal calcareous ground, old overgrown slope and moraine scree with larger rocks and boulders, in shade, relatively warm place, partly protected from direct rain by tree canopies, average precipitation ~ 3.000 mm/year, average temperature 7 - 9 deg C, elevation 600 m (1.970 feet), alpine phytogeographical region. Substratum: debarked trunk of Picea abies lying on ground in its late disintegration stage.Place: Lower Trenta valley, between villages Soa and Trenta, next to the trail from Trenta 2b cottage to abandoned farmhouse 'Strgulc', East Julian Alps, Posoje, Slovenia EC.Comment: Fuligo septica is probably the most common and widely known Myxomicete. The latest monograph on Myxomycetes I have (Ref.:1) describes six varieties of this species, which differ mostly in cortex structure (single versus double layered) and color of different parts of sporocarp and plasmodium. Fuligo septica var. flava should have vivid yellow aethalia, yellow inner lime and yellow plasmodium. Two days before I took these pictures I had seen the plasmodium, which was in a form of vividly yellow colored patch of densely packed small half-spheres. The rest of traits of Fuligo septica var. flava also fit well to my observation.Spores minutely warty, globose to subglobose. Dimensions: 8 [8,4 ; 8,7] 9,1 x 7,4 [8 ; 8,2] 8,7 microns; Q = [1 ; 1,07] 1,1; N = 25; C = 95%; Me = 8,5 x 8,1 microns; Qe = 1,1.

Didymium squamulosum (Alb. & Schwein.) Fr., Syn.: Cionium squamulosum (Alb. & Schwein.) Spreng., Diderma squamulosum Alb. & Schwein., Didymium effusum Link, Physarum effusum Link.Family: DidymiaceaeEN: no vernacular name found, DE: no vernacular name foundSlo.: no vernacular name foundDat.: Oct. 30. 2020Lat.: 46.360322 Long.: 13.702932Code: Bot_1344/2020_DSC1440Habitat: Former pasture partly overgrown with tall herb, bushes and scattered trees; slightly inclined terrain, southeast aspect; calcareous, skeletal, colluvial ground; open, sunny place; exposed to direct precipitations, average precipitation ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 600 m (1.970 feet), alpine phytogeographical region. Substratum: bark of a dead trunk of Juglans regia in its initial disintegration stage laying on ground, partly sitting on Collema sp. (probably Collema crispum = Blennothallia crispa) thallus.Place: Lower Trenta valley, right bank of river Soa; between villages Soa and Trenta; near Trenta 2b cottage, East Julian Alps, Posoje, Slovenia EC.Comment: Habit and presence of lime crystals speak almost certainly in favor of the genus Didymium. Dimensions of spores inclined me toward Didymium melanospermum (Pers.) T. Macbr. at first. However, other traits, particularly furrowed stalks, whitish stalk color (should be bark to black) and presence of lime in them (it should be absent), changed my initial supposition in favor to similar Didymium squamulosum (Alb. & Schwein.) Fr. in spite of the fact that measured spore dimensions doesn't fit so nicely to the second option. Another discrepancy of the find (related to booth species) is the fact that vast majority of the sporocarps appeared sessile, while they should normally be distinctly stalked and only rarely 'sessile'. According to literature Didymium squamulosum is considered a very variable species and apparently sessile sporocarps are found occasionally too, so they may not be a severe argument against this determination.Description: Sporocarps up to 1.1 mm tall, most of them seemingly sessile having rudimentary stalks hidden in strongly umbicilate sporocysts below; only a few distinctly stalked; sporocysts sub-globose or oblate, 0.6-1 mm in diameter, when wet bluish-gray, half dry pale-gray, when dry white; with simple, membranous, colorless to light-yellowish, translucent peridium covered by a thick layer of crystalline lime; crystals usually larger than spores; (hypo)columella present, flattened, perimeter about 1/3 or slightly less of the sporocysts perimeter; white to beige, light brownish (best seen in transparent light); capillitium thin, scantily branched with rare, small nodular swellings; attached to peridium. Stalks short, mostly hidden; some distinct but not longer than 2/3 of sporocysts diameter, longitudinally striate, No confluent plasmodial form observed at the site of stalk attachment to substrate.To our knowledge, up to present three observations of this rare (or overlooked) species in Slovenia have been described up to now (Ref.:5, Ref.:6 and Ref.:7). Microscopy: Spores densely warted (< 0.5m high warts), globose to sub-globose dark brown to black on mass (dry); dimensions: (10,5)10,8 - 12(12,6) (9,9)10,4 - 11,5(11,9) m; Q = 1 - 1,1; N = 21; Me = 11,4 10,9 m; Qe = 1.

Fuligo septica var. flava (Pers.)

Substratum: debarked roots of dead Picea abies, still standing.Place: Lower Trenta valley, between villages Soa and Trenta, next to the trail from Trenta 2b cottage to abandoned farmhouse 'Strgulc', East Julian Alps, Posoje, Slovenia EC.Comment: Fuligo septica is probably the most common and widely known Myxomicete. One of its varieties - Fuligo septica var. flava - has vivid yellow aethalia and yellow plasmodium (I haven't seen it this time). Yet, this typical color pertains only to mature but still fresh aethalia (pictures 10-13). With time cortex becomes darker, almost golden (picture 14), then black inside becomes visible (pictures 15, 16). In next phase cortex become whitish (pictures 17, 18) and finally it disappears and only blackish-reddish-brown spore mass is seen (pictures 19, 20). It is interesting that this find was found only a few meters away of the site where I photographed the same species two years ago (see Album Fuligo septica var. flava - I, Dec. 2014) (see MO observations #194527). In both observations spores are unusually large.Spores minutely warty, globose to subglobose. Dimensions: 8,5 [9,1 ; 9,4] 10 x 8 [8,6 ; 8,8] 9,4 microns; Q = [1 ; 1,08] 1,1; N = 35; C = 95%; Me = 9,2 x 8,7 microns; Qe = 1,1.

Dog vomit slime mold, Flowers of Tan, DE: Lohblte, HexenbutterSlo.: reslov cvetDat.: Oct. 19. 2015 - 13:55; about 5 days after previous picturesCode: Bot_920/2015_DSC9418All observations: Lat.: 46.36005 Long.: 13.70239Habitat: edge of former pasture; partly overgrown with Picea abies, Ostrya carpinifolia, Fagus sylvatica; slightly inclined mountain slope, southwest aspect, locally almost flat terrain, shallow, stony, calcareous ground; open, mostly sunny place; exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7 - 9 deg C, elevation 595 m (1.950 feet), alpine phytogeographical region. Temperatures from Oct. 11. to Oct. 19. were between 1 to 12 deg C, from Oct. 13. to Oct. 19. there were periods of very heavy rains. Substratum: on bark of a piece of cut down Picea abies trunk deposited on a pile of cut down Picea abies wood and branches; wood in its initial decomposition phase, mostly still in bark.Place: Lower Trenta valley, between villages Soa and Trenta, right bank of river Soa; near 'Na Melu' place somewhat south of Trenta 2b cottage; East Julian Alps, Posoje, Slovenia EC.Comments: This Myxomicete almost certainly belongs to genus Fuligo. The first measurement of its spores made on live material distinguished it from the most common species in this genus Fuligo septica. Fuligo septica has smaller spores, from 6 to 9 microns in diameter, while most of other species have spores larger than 10 microns in diameter. Also colors of either aethalium (fruiting body formed from all or most of the plasmodium), or of plasmodium (acellular, multinucleate mass of protoplasm, which crawls around, feeds and grows before it forms aethalium), or of inner lime (structure within spore mass of mature aethalium) of this observation fit perfectly to none of the five varieties of Fuligo septica described in Ref.:3 (namely: F.s. var. septica, F.s. var. flava, F.s. var. candida, F.s. var. rosea and F.s. var. rufa). Using the key of the genus Fuligo given in Ref.: 1 one comes straight to Fuligo intermedia Macbr., syn.: Fuligo cinerea var. ecorticata Lister. The measured average spore diameter and spore surface fit best, but not perfect, to this species (pertains to the first measurement of spores). But there are important differences from the descriptions of this species in the literature. For example, cortex (a more or less thick outer layer of an aethalium) is not thin as it should be. Hypothallus (a thin layer between the substrate and fruiting body) was membranous and of several layers (as it should be according to Ref.:1) but it was only locally white. Dominant colors were yellow and even red. According to literature the color of aethalium should be dirty white, pale gray or brownish. This was so only on a rather limited part of aethalium (see pictures 30-32 upper part of the aethalium). Aethalium was mostly black with partly deep reddish tint. The dried sample of the find has been analyzed at the Slovenian Forestry Institute by Mrs. Sanja Behri. Spores have been measured twice (on two sets of equipment). Significantly smaller average dimension (8.5-8.7 m and 8.8 m; n > 20) found. This fits well to Fuligo septica. However, the other observed discrepancies from this species remain. A most probable but unverified assumption is that very bad weather with low temperatures during the development of the aethalium caused unusual properties. The quite significant differences in the results of spore dimensions of all three measurements could be the consequence of an uneven development of spore mass in different parts of aethalium, which were analyzed. But this is only an assumption. Because of that a reliable determination of the find remains open.Spores minutely warted. Dimensions: 9.6 [10.2 ; 10.5] 11.1 x 8.4 [9.1 ; 9.4] 10.1 microns; Q = 1 [1.1] 1.2; N = 30; C = 95%; Me = 10.4 x 9.2 microns; Qe = 1.1.

Fuligo septica var. flava (Pers.) Morgan, syn.: Mucor septicus L., Aethalium flavum (Pers) LinkFlowers of Tan, DE: Gelbe LohblteSlo.: reslov cvet, rumeni razliekDat.: Sept. 05. 2014Lat.: 46.35965 Long.: 13.70116Code: Bot_832/2014_DSC3621Habitat: mixed wood, Fagus sylvatica and Picea abies dominant, moderately southeast inclined mountain slope, shallow, skeletal calcareous ground, old overgrown slope and moraine scree with larger rocks and boulders, in shade, relatively warm place, partly protected from direct rain by tree canopies, average precipitation ~ 3.000 mm/year, average temperature 7 - 9 deg C, elevation 600 m (1.970 feet), alpine phytogeographical region. Substratum: debarked trunk of Picea abies lying on ground in its late disintegration stage.Place: Lower Trenta valley, between villages Soa and Trenta, next to the trail from Trenta 2b cottage to abandoned farmhouse 'Strgulc', East Julian Alps, Posoje, Slovenia EC.Comment: Fuligo septica is probably the most common and widely known Myxomicete. The latest monograph on Myxomycetes I have (Ref.:1) describes six varieties of this species, which differ mostly in cortex structure (single versus double layered) and color of different parts of sporocarp and plasmodium. Fuligo septica var. flava should have vivid yellow aethalia, yellow inner lime and yellow plasmodium. Two days before I took these pictures I had seen the plasmodium, which was in a form of vividly yellow colored patch of densely packed small half-spheres. The rest of traits of Fuligo septica var. flava also fit well to my observation.Spores minutely warty, globose to subglobose. Dimensions: 8 [8,4 ; 8,7] 9,1 x 7,4 [8 ; 8,2] 8,7 microns; Q = [1 ; 1,07] 1,1; N = 25; C = 95%; Me = 8,5 x 8,1 microns; Qe = 1,1.

Didymium squamulosum (Alb. & Schwein.) Fr., Syn.: Cionium squamulosum (Alb. & Schwein.) Spreng., Diderma squamulosum Alb. & Schwein., Didymium effusum Link, Physarum effusum Link.Family: DidymiaceaeEN: no vernacular name found, DE: no vernacular name foundSlo.: no vernacular name foundDat.: Oct. 30. 2020Lat.: 46.360322 Long.: 13.702932Code: Bot_1344/2020_DSC1440Habitat: Former pasture partly overgrown with tall herb, bushes and scattered trees; slightly inclined terrain, southeast aspect; calcareous, skeletal, colluvial ground; open, sunny place; exposed to direct precipitations, average precipitation ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 600 m (1.970 feet), alpine phytogeographical region. Substratum: bark of a dead trunk of Juglans regia in its initial disintegration stage laying on ground, partly sitting on Collema sp. (probably Collema crispum = Blennothallia crispa) thallus.Place: Lower Trenta valley, right bank of river Soa; between villages Soa and Trenta; near Trenta 2b cottage, East Julian Alps, Posoje, Slovenia EC.Comment: Habit and presence of lime crystals speak almost certainly in favor of the genus Didymium. Dimensions of spores inclined me toward Didymium melanospermum (Pers.) T. Macbr. at first. However, other traits, particularly furrowed stalks, whitish stalk color (should be bark to black) and presence of lime in them (it should be absent), changed my initial supposition in favor to similar Didymium squamulosum (Alb. & Schwein.) Fr. in spite of the fact that measured spore dimensions doesn't fit so nicely to the second option. Another discrepancy of the find (related to booth species) is the fact that vast majority of the sporocarps appeared sessile, while they should normally be distinctly stalked and only rarely 'sessile'. According to literature Didymium squamulosum is considered a very variable species and apparently sessile sporocarps are found occasionally too, so they may not be a severe argument against this determination.Description: Sporocarps up to 1.1 mm tall, most of them seemingly sessile having rudimentary stalks hidden in strongly umbicilate sporocysts below; only a few distinctly stalked; sporocysts sub-globose or oblate, 0.6-1 mm in diameter, when wet bluish-gray, half dry pale-gray, when dry white; with simple, membranous, colorless to light-yellowish, translucent peridium covered by a thick layer of crystalline lime; crystals usually larger than spores; (hypo)columella present, flattened, perimeter about 1/3 or slightly less of the sporocysts perimeter; white to beige, light brownish (best seen in transparent light); capillitium thin, scantily branched with rare, small nodular swellings; attached to peridium. Stalks short, mostly hidden; some distinct but not longer than 2/3 of sporocysts diameter, longitudinally striate, No confluent plasmodial form observed at the site of stalk attachment to substrate.To our knowledge, up to present three observations of this rare (or overlooked) species in Slovenia have been described up to now (Ref.:5, Ref.:6 and Ref.:7). Microscopy: Spores densely warted (< 0.5m high warts), globose to sub-globose dark brown to black on mass (dry); dimensions: (10,5)10,8 - 12(12,6) (9,9)10,4 - 11,5(11,9) m; Q = 1 - 1,1; N = 21; Me = 11,4 10,9 m; Qe = 1.
