location
Trenta valley, west of village Trenta, right bank of river Soča, next to 'Soška pot' trail, East Julian Alps (Posočje, Slovenia)notes Slo.: mehka skutovka - Habitat: 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. - 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) μ, Q = 2.62 (SD = 0.23), n = 21. Olympus CH20, NEA 100x/1.25, magnification 1.000 x, oil, in water. Basidia dimensions: 16.1 (SD = 1.8) x 4.4 (SD = 0.4) μ, n = 7. Olympus CH20, NEA 40x, magnification 400 x, in water, Congo red. AmScope MA500 digital camera. - Protected according to: Uredba o zavarovanih prostoživečih vrstah gliv, Uradni list RS, št.58/2011 (Regulation of protected wild fungi, Official Gazette of Republic Slovenia, no. 58/2011), (2011). - Herbarium: Mycotheca and lichen herbarium (LJU-Li) of Slovenian Forestry Institute, Večna pot 2, Ljubljana, Index Herbariorum LJF - Ref.: (1) A.
