Wraber, 1969).Substratum: large Fagus sylvatica trunk in its late disintegration state lying on ground.Place: Lower Trenta valley, between villages Soa and Trenta, left bank of river Soa, 200 m upstream from Matev's (Trenta 1) footbridge, between Soa trail and the river, East Julian Alps, Posoje, Slovenia.Comments (pertain to pictures in the Flicks album Crepidotus crocophyllus): Crepidotus crocophyllus seems to be a rare find in Europe. According to Slovenian database Boletus informaticus (Ref.: 6) it is known from only four MTB sub-quadrants in the country, in neighboring Austria only 8 records are documented (Ref.: 7), in Germany it is considered rare to extremely rare (Ref.3). This is much different in North America, where the species is considered as one of the most common in the genus (Ref.: 5). Crepidotus crocophyllus is among the most beautiful species of the genus with its orange gills and strong 'geometric' impact. Others are mostly whitish and much less remarkable.Description: about 12 pilei present, from 3 to 6.3 cm wide and 2 to 3.8 cm from substrate; pilei cutis dry, not waxy, doesn't peel away; smell and taste indistinctive; 10% KOH reaction on gills reddish; SP abundant, brown, oac784.Spores mostly globose, some sub-globose, minutely warty. Dimensions: (5.8) 6.1 - 7 (7.5) (5.7) 5.9 - 6.8 (7.1) m; Q = 1 - 1.07 (1.1); N = 40/1; Me = 6.5 6.3 m; Qe = 1. Olympus CH20, NEA 100x/1.25, magnification 1.000 x, oil; in water, fresh material.
