Habitat: old partly overgrown pasture, near mixed wood edge, moderately southeast inclined foot of a mountain; open, dry, sunny place; shallow, skeletal, calcareous ground, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 630 m (2.070 feet), alpine phytogeographical region. - Substratum: north side of a stump of Picea abies (on decorticated part) cut down three years ago. - Comment: Highly distinctive traits of Stemonitis flavogenita are typically zig-zag bent columella with a kind of plate at the end just before the end of sporangia (Ref.:1). It is not gradually tapering toward the end of sporocarp as with other species of genus Stemonitis. It is also distinguished by the presence of membranous expansions in the capillitium. Also agreement of macroscopic properties fit well to literature, so I hope the determination is correct. This observation may be interesting since this species is listed neither in Boletus Informaticus data base, Mycotheca and lichen herbarium (LJU-Li) of Slovenian Forestry Institute nor in official Slovenian fungi checklist. - Sporocarp color rusty, oac719; spores on mass chocolate brown, oac635. Stalks 2.5 to 3 mm long, total length of sporangia 9 mm, all of them were fairly the same length, very closely tufted, their tips blunt.

Slo.: paliasta hladetinka, rogata sluzavka - syn.: Byssus fruticulosa Mll. - Habitat: Fagus sylvatica forest with some Picea abies; moderately inclined slope at the foot of a mountain, northwest aspect; calcareous, skeletal forest ground; in shade; next to a river, humid air conditions; partly protected from direct rain by tree canopies; average precipitation ~ 3.000 mm/year, average temperature 7 - 9 deg C, elevation 525 m (1.720 feet), alpine phytogeographical region. Substratum: almost totally rotten tree stump; probably Fagus sylvatica, possibly Picea abies.Comment: Ceratiomyxa fruticulosa var. fruticulosa is one of the most distinctive and wide-spread myxomycetes (nowadays Protosteliomycetes). It is easy to recognize it since nothing similar exists outside tropical regions. Because of its bright white color, it is also easy to spot. Its genus name Ceratiomyxa comes from Greek words keras and myxa. The first means horn(s) and the second slime. And indeed it consists (in most cases) of many erects columns made of slimy substance. Unlike of all other myxomycetes the columns bear individual spores externally, on long stalks (see picture 2b, middle-left). However, it can appear also in a much different form, which is treated by some authors as separate species Ceratiomyxa poroides Alb. & Schwein or a subspecies of Ceratiomyxa fruticulosa. Then it looks like spongy, poroid or effused crust, much similar to some poroid basidiomycetes. The plasmodium of Ceratiomyxa fruticulosa is watery translucent (see picture 2a, slime among developed columns). It initially forms whitish blobs (see picture 1b, upper part), which in mature stage develop into simple or sparsely branched columns covered by stalked, white spores looking similar to glandular hairs of higher plants.

Slo.: reslov cvet - syn. Mucorsepticus L., Reticularia septica (L.) With., Aethalium septicum (L.) Fr., Fuligo varians Sommerf. - The aethalium picture taken on July 21. 2014.(Figs.13 - 16) - Habitat: old partly tree overgrown pasture, near mixed wood edge; moderately southeast inclined foot of an old overgrown scree slope; open, dry, sunny place; shallow, skeletal, calcareous ground, exposed to direct rain, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 630 m (2.070 feet), alpine phytogeographical region. - Substratum: a stump of Picea abies cut down three years ago. - Comment: Myxomycetes are poorly known yet very interesting creatures. For decades they have been shuffled back and forth between the animal and plants kingdoms until recognized as separate creatures. They are not animals because they proliferate by spores. They are also not plants since they crumble around (an animal like ability) and fix themselves firmly to substrate only at the end of their life cycle. They don't produce their own food like plants but feed by 'hunting' (actually engulfing) bacteria and tiny bits of other organic matter, which is another animal like feature. The first stage in their development cycle, which is observable in the field, is called plasmodium. Earlier stages (from myxoflagellates, myxoamoebae, to zygote) are microscopic and can be observed only in labs. Plasmodium is a single giant living cell, a clump of protoplasm filled with thousands of cell nuclei, crawling around, eating bacteria and growing. Some of such plasmodia are the largest cells of living creatures known. In some species they can measure several meters across or weight up to 20 kg. That it much larger than ostrich's eggs, which are popularly considered as 'largest living cells'! Plasmodia could be found in the field, some are even brightly colored and easy to spot; however, it is almost impossible to determine to which species they belong. Plasmodium of Fuligo septica is commonly described like disgusting mucus, spilled scrambled eggs, dogs vomiting and other 'benevolent' portrayals. - When the time is right or delicate environmental conditions required for growth worsen plasmodia eventually evolves (usually almost completely) into sporocarps of different forms. These are bodies producing spores and then vanishing. In genus Fuligo sporocarp is a cushion like aethalium sitting on a thin whitish, 'fibrous' layer called hypothallus (Fig.14.). These'cushions' are what one usually finds in the field. But, other Myxomycetes develop also many other forms of sporocarps full of beauty, delicacy and imagination. Aethalia of Fuligo septica are usually covered with a kind of crust called cortex, which is brittle and soon crumbles away. In humid conditions it may not fully develop (Ref.1). Inside a mature aethalium there is a mesh of thin tubes or fibers called capillitium and zillions of dark brown spores. Fuligo septica has characteristic nodes on capillitial tubes, which are clearly seen on Fig. 4M. In due course the aethalium decomposes almost entirely into spore mass (Fig.17., 18.), which are sooner or later blown or washed away (Fig.20. taken about three weeks after the first photo). Size and shape of spores and structure of their surface are important traits for species determination. - Cushion-shaped aethalium measured approximately 14 x 5 cm and was about 3 cm thick. Spores are minutely warty and 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 = 1,05.

Syn.: Arcyria nutans (Bull) Grev - Habitat: Overgrown former grassland; dominant trees Ailanthus altissima, Fraxinus ornus, Corylus avellana, Fagus sylvatica, Juglans regia, Tilia sp., Prunus domestica; next to an abandoned farmhouse; flat terrain, calcareous ground; full shade, quite humid and relatively warm place, partly protected from direct rain by tree canopies; average precipitation ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 590 m (1.950 feet), alpine phytogeographical region. - Substratum: vertical surface of dead, still standing trunk of Juglans regia partly still in bark fully covered by a Polyporaceae, probably Inonotus sp.; about 1 m (three feet) above ground, northeast oriented surface of the trunk. - Comment: Long, hanging and very shortly stipitate sporocarps distinguish this species from others in Myxomycetes genus Arcyria. Sporocarps 8 - 13 mm long, about 1 mm diameter, flexible. Stalk very short, hard to observe, almost sessile sporocarps; sporocarps ocher-yellow, oac848; SP abundant, ocher-yellow, oac 856. - Spores subglobose and almost smooth, scattered warts hardly visible with my equipment. Dimensions: 8.7 (SD = 0.3) x 8.3 (SD = 0,2) μ, Q = 1.05 (SD = 0.02), n = 30. Olympus CH20, NEA 100x/1.25, magnification 1.000 x, oil, (picture of spores and capillitium threads). Bausch & Lomb 4/0.10, magnification 40x, in water (picture of capillitium). AmScope MA500 digital camera. - Ref.: (1) B. Ing, The Myxomycetes of Britain and Ireland, The Richmond Publ.
