Leptoporus mollisSlo.: mehka skutovkaDat.: Oct. 31. 2013Lat.: 46.38337 Long.: 13.75061Code: Bot_768/2013_DSC9113Habitat: Mixed wood, east inclined fairly steep mountain slope, calcareous ground, humid place, in shade, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 6-8 deg C, elevation 640 m (2.100 feet), alpine phytogeographical region.Substratum: large, approximately 70 cm (2.3 feet) in diameter, debarked fallen trunk of Picea abies in its late stage of disintegration.Place: Trenta valley, west of village Trenta, right bank of river Soa, next to 'Soka pot' trail, East Julian Alps, Posoje, Slovenia EC Comments: This is an interesting fungus from several reasons. First it is quite rare. Second it is the only known species in the genus Leptoporus. Third it is a real surprise when you touch it - surprisingly spongy and so soft, that it is hard to handle it without damaging it. Indeed in strong contrast to what one expects from similar bracket fungi on wood.Growing in groups, many fruit bodies present on the log; sessile brackets up to 5 cm wide, up to 2.5 cm off the substrate and about 2 cm thick, trama layer up to 12 mm thick, pore layer 5-7 mm thick, brackets partly fused; thickly effuse-reflexed form up to 5 x 3.5 cm, totally resupinated patches up to 20 x 6 cm; bruising reddish-brown when touched; taste distinctly aromatic-bitter; smell mushroomy, pleasant, lightly acid; flesh very soft like watery white cheese; no SP obtained, spores collected directly from pore surface using a soft brush; no hypha clamps observed; 5% KOH reaction on pore surface deep brown with red tint; the same on pileus, yet slower reaction and less intensive. Spores' width fits expectations; however, their length is somewhat too small. Probably they were not yet mature.Spores smooth. Dimensions (only larger spores have been measured): 4.7 (SD= 0.2) x 1.8 (SD = 0.1) , Q = 2.62 (SD = 0.23), n = 21. Olympus CH20, NEA 100x/1.25, magnification 1.000 x, oil, in water.

Postia subcaesia, syn.: Oligoporus subcaesius, Tyromyces subcaesius, Spongiporus subcaesiusBlueing Bracket, Blauer SaftporlingSlo.: modrikasti skutovecDat.: Oct. 09, 2013Lat.: 46.39815 Long.: 13.70048Code: Bot_759/2013_DSC8535Habitat: Mixed forest, Picea abies and Fagus sylvatica dominant, almost flat terrain, calcareous ground; full shade; humid place, partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 4-6 deg C, elevation 1.000 m (3.300 feet), alpine phytogeographical region.Substratum: on dead rotting branch lying on ground and on rotten half buried roots of Fagus sylvatica, partly still in bark.Place: Zadnja Trenta valley, left bank of (mostly) dry Soa river bed, north of Bavki Grintavec mountain, East Julian Alps, Posoje, Slovenia EC Comments: This observation was first determined as Postia caesia (see former text in brackets below). But, a kind explanation of Mr. Gnter Sturm, Germany, having long 'mileage' in Polyporaceae, and the paper of David (1974), Ref.: (8) convinced me that the correct determination should be Postia subcaesia. Now substratum fits better. Also habitus of the find fits better to the new determination. Pileus of P. caesia is of more uniform colors and never as strongly zonate as in this observation. Another trait, which fits better now, is the fact that the pilei color didn't changed distinctly blue when bruised. Nevertheless, spore dimensions still don't fit to data from literature. May be Ryvarden's comment in Ref.: (7), p 405, regarding distinguishing both species: 'However, there are some disturbing intermediate specimens on hardwoods.' explains the situation?Former text:[This beautifully blue polypore could eventually be Oligoporus subcaesius. Unfortunately, the distinguishing traits between O. caesius and O. subcaesius seem to be treated quite inconsistently in the literature available to me. Oligoporus caesius should principally thrive on wood of conifers (with rare but documented exceptions) and should have spores wider than 1.5 , while Oligoporus subcaesius is found on broadleaved trees and should have spores narrower than 1.5 (as per Ref.:(5) and Ref.:(1)). Contrary, Ref.: (4) states narrower than 1.5 spores for O. caesius (a typo?). Also the information about spore shape (allantoid versus cylindrical) is inconsistently given in different sources. In this observation measured spore width speaks in favor to O. caesius (according to Ref.:(1) and (5)), while substratum doesn't support this decision. Since exceptions with regard to substratum are known, and based on quite distinctively blue color of the pilei and their size (O. subcaesius should be significantly larger according to Ref.:(1)) I decided for O. caesius, but this may be incorrect. ]Growing in a small group of about 6 pilei of different size; pilei up to 6 x 4 cm across; flesh soft, fibrous; SP very faint, whitish(?), oac857(?).Spores smooth, cylindrical and moderately allantoid.

Trametes pubescens (Schumach.: Fr.) Pilt, syn.: Coriolus pubescens (Schumach.: Fr.) Murr.DE: Samtige TrameteSlo.: puhasta ploskocevkaDat.: Nov. 17. 2015Lat.: 46.40365 Long.: 13.74211Code: Bot_927/2015_DSC9883Habitat: mixed wood, Fagus sylvatica, Picea abies, dominant trees with some Larix decidua and Fraxinus excelsior; steep mountain slope, west aspect, however in shade of mountains during winter months; rather cool and humid place; calcareous ground; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 5 - 6 deg C, elevation 790 (2.600 feet), alpine phytogeographical region.Substratum: large, very old Fagus sylvatica, the tree is still alive, but fungus is growing on partly dead part of it, still in bark.Place: Zadnja Trenta valley; at the border of Forest reserve Kukla; about 100 m southwest of the memorial of Dr. Julius Kugy, poet and mountaineer of Julian Alps; near switchback no.48 of Vri alpine road, East Julian Alps, Posoje, Slovenia EC.Comments: This find has posed very interesting challenges for determination. Several options have been considered but apparently none fit to the find. Experts have been consulted but no definite solution found. Finally a sample has been sent to Dr. Leif Ryvarden, University of Oslo who determined it as Trametes pubescens. Many thanks to all involved in the problem solving - Dr. Nikica Ogris and Andrej Piltaver, Slovenian Forestry Institute, Bojan Rot, Bovec, Branko Vrhovnik, Horjul and specially to Prof. Ryvarden for his final determination.The main source of identification problems is probably very untypical shape of the pilei. Trametes pubescens has usually relatively thin pilei. According to the key of genus Trametes given in Krieglsteiner (2000), p585 the pilei are about 0.5 (1) cm thick, Ryvarden (2014), p417 states: "... Basidiocarps thin ... context up to 5 mm ... pore layer up to 4 mm thick..." and Bernicchia (2005), p535 gives " ... context 3-5 mm and pore layer 1-5 mm thick... ". The pilei found were up to 5 cm thick and in most cases triquetrous in cross-section. Also spores are significantly longer than normally expected.Growing in a few groups on the same part of a large tree; altogether more than 200 pilei present; majority of them laterally confluent, imbricate, some single; some effuse-reflexed, most of them triquetrous in cross-section; pilei dimensions: 8-10(16) x 4-5(6.5) cm and 2.5-5 cm thick; pore layer up to 8 mm thick; context of very low specific weight, corky, similar to dry Piptoporus betulinus; when dry quite firm, brittle, brakes to pieces; smell (of almost dry pilei) very mild but distinctive on what? ; taste indistinctive at the beginning, after a while mild and interesting, again on what?; 5% KOH reaction on context and pileus surface yellow-ocher with orange tint, on pores the same color but less distinctive; SP scarce, but distinctive (after making pilei moist and at 18-20 deg C), whitish-beige, oac851; fungi causing white root according to analysis of the wood made at the Forestry Institute of Slovenia.Spore dimensions determined twice from SP of different pilei. First measurement (pilei taken on Nov. 18. 2015): 7 [7.8; 8] 8.8 x 2 [2.4; 2.5] 2.9 microns; Q = 2.6 [3.2; 3.4] 3.9; N = 49; C = 95%; Me = 7.9 x 2.4 microns; Qe = 3.3.

Trametes pubescens (Schumach.: Fr.) Pilt, syn.: Coriolus pubescens (Schumach.: Fr.) Murr.DE: Samtige TrameteSlo.: puhasta ploskocevkaDat.: Nov. 17. 2015Lat.: 46.40365 Long.: 13.74211Code: Bot_927/2015_DSC9883Habitat: mixed wood, Fagus sylvatica, Picea abies, dominant trees with some Larix decidua and Fraxinus excelsior; steep mountain slope, west aspect, however in shade of mountains during winter months; rather cool and humid place; calcareous ground; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 5 - 6 deg C, elevation 790 (2.600 feet), alpine phytogeographical region.Substratum: large, very old Fagus sylvatica, the tree is still alive, but fungus is growing on partly dead part of it, still in bark.Place: Zadnja Trenta valley; at the border of Forest reserve Kukla; about 100 m southwest of the memorial of Dr. Julius Kugy, poet and mountaineer of Julian Alps; near switchback no.48 of Vri alpine road, East Julian Alps, Posoje, Slovenia EC.Comments: This find has posed very interesting challenges for determination. Several options have been considered but apparently none fit to the find. Experts have been consulted but no definite solution found. Finally a sample has been sent to Dr. Leif Ryvarden, University of Oslo who determined it as Trametes pubescens. Many thanks to all involved in the problem solving - Dr. Nikica Ogris and Andrej Piltaver, Slovenian Forestry Institute, Bojan Rot, Bovec, Branko Vrhovnik, Horjul and specially to Prof. Ryvarden for his final determination.The main source of identification problems is probably very untypical shape of the pilei. Trametes pubescens has usually relatively thin pilei. According to the key of genus Trametes given in Krieglsteiner (2000), p585 the pilei are about 0.5 (1) cm thick, Ryvarden (2014), p417 states: "... Basidiocarps thin ... context up to 5 mm ... pore layer up to 4 mm thick..." and Bernicchia (2005), p535 gives " ... context 3-5 mm and pore layer 1-5 mm thick... ". The pilei found were up to 5 cm thick and in most cases triquetrous in cross-section. Also spores are significantly longer than normally expected.Growing in a few groups on the same part of a large tree; altogether more than 200 pilei present; majority of them laterally confluent, imbricate, some single; some effuse-reflexed, most of them triquetrous in cross-section; pilei dimensions: 8-10(16) x 4-5(6.5) cm and 2.5-5 cm thick; pore layer up to 8 mm thick; context of very low specific weight, corky, similar to dry Piptoporus betulinus; when dry quite firm, brittle, brakes to pieces; smell (of almost dry pilei) very mild but distinctive on what? ; taste indistinctive at the beginning, after a while mild and interesting, again on what?; 5% KOH reaction on context and pileus surface yellow-ocher with orange tint, on pores the same color but less distinctive; SP scarce, but distinctive (after making pilei moist and at 18-20 deg C), whitish-beige, oac851; fungi causing white root according to analysis of the wood made at the Forestry Institute of Slovenia.Spore dimensions determined twice from SP of different pilei. First measurement (pilei taken on Nov. 18. 2015): 7 [7.8; 8] 8.8 x 2 [2.4; 2.5] 2.9 microns; Q = 2.6 [3.2; 3.4] 3.9; N = 49; C = 95%; Me = 7.9 x 2.4 microns; Qe = 3.3. Second measurement (pilei taken on Nov. 23. 2015): 6.1 [7.3; 7.6] 8.9 x 2 [2.3; 2.4] 2.8 microns; Q = 2.5 [3.1; 3.2] 3.9 ; N = 62 ; C = 95%; Me = 7.5 x 2.4 microns; Qe = 3.2. Basidia clavate, dimensions: 14.2 [15.8; 17.7] 19.4 x 4.1 [5; 6.1] 7 microns; Q = 2.3 [2.8; 3.3] 3.8; N = 8; C = 95%; Me = 16.8 x 5.5 microns; Qe = 3.1. Hyphal system trimitic.
