Observation 193924: Crepidotus mollis (Schaeff.) Staude
When: 2014-12-09
(46.3562° 13.6992° 525m)

Notes: Code: Bot_854/2014_DSC5207

Habitat: alpine valley, river bank, locally almost flat terrain, calcareous ground, river bank vegetation mostly consisting of Salix eleagnos, Picea abies and some Fagus sylvatica; humid air and ground, partly sunny, exposed to direct rain; average precipitations ~ 3.000 mm/year, a average temperature 8-10 deg C, elevation 525 m (1.720 feet), alpine phytogeographical region.

Substratum: dead wood, stump of a cut down Salix eleagnos.

Place: Lower Trenta valley, left bank of river Soča, slightly downstream from farmhouse Matevž, Trenta 3, East Julian Alps, Posočje, Slovenia EC.

Comments: Growing in a group of five pilei; pilei small or still young; pilei across 0.9 – 2 cm, maximally 7 mm thick; pilei with gelatinous cutis easily peeling off, very sticky; stipe absent, some white mycelium present at the point of attachment; taste mild, indistinctive, smell none; flesh soft, pliant, watery; SP abundant, neutral brown, oac783. I follow taxonomy given in Krieglsteiner (2001) who distinguishes two varieties of Crepidotus mollis, var. mollis and var. calolepsis. The latter on has scales on its pileus (which was not the case in my find) and is considered by some authors as a separate species.
