46.3608° 13.7011° 625m
Code: Bot_915/2015_DSC9114 and Bot_919/2015_DSC9383
Habitat: mixed wood, Picea abies, Ostrya carpinifolia and Fagus sylvatica dominant trees, moderately inclined mountain slope, southeast aspect; colluvial, calcareous, skeletal ground; relatively dry and warm place; in shade; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 625 m (2.050 feet), alpine phytogeographical region.
Substratum: cutoff, partly debarked trunk of Picea abies lying on ground; on bark, on debarked wood and on laterally cut wood.
Place: Lower Trenta valley, right bank of river Soča, between villages Soča and Trenta, wood side on the west side of the ‘Na melu’ pasture; near cottage Trenta 2b, East Julian Alps, Posočje, Slovenia EC.
Comments: Growing on bark, on debarked wood, in between and on laterally cut wood in many fruit bodies, which were in resupinate, effuse-reflexed and pileate form; the resupinate form up to 12 × 6 cm in size, pilei confluent and up to 25 × 6(10) mm large; context duplex with a gelatinous layer above (very thin) tube layer and white cottony upper layer, all layers together 1.5 – 2.5 mm thick; fruitbodies soft, pliant when fresh and hard when dry; smell pleasant, mushroomy, slightly aromatic like perfumed soap, taste indistinctive (tasting on Picea bark); 5% KOH reaction on pore layer distinctly red, on pilei upper surface less pronounced, muddy orange-brown; SP very faint, probably whitish.
Comparing pictures in the literature and internet (pore layer color?), the find could also be similar and closely related Skeletocutis carneogrisea. However, the latter has somewhat smaller spores, is almost always resupinated (doesn’t form pilei) and red KOH reaction is not reported (Ref.: 1). Since other traits fit well to literature I decided for Skeletocutis amorpha.
