Description:

Slo.: obrobljena kumica - syn.: Galerina autumnalis (Peck) A.H. Sm. & Singer, Galerina unicolor (Vahl) Singer, Pholiota marginata (Batsch) Qul. - Habitat: pasture, slightly inclined mountain slope, southeast aspect; colluvial, skeletal, calcareous ground; full sun, dry and relatively warm place; exposed to direct rain; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 625 m (2.050 feet), alpine phytogeographical region.Substratum: moss overgrown stump of a cut down Picea abies in its late phase of disintegration.Comments: This mushroom usually appears in older literature as Galerina autumnalis. But extensive DNA study (Gulden and collaborators, 2001) has synonymized that species - along with Galerina oregonensis, Galerina unicolor, and Galerina venenata - with the older, European species first described in the 18th century, Galerina marginata. The mushroom is deadly poisonous (look at English common name). Growing in a loose group of about 15 pilei; pilei diameter 1.4 - 4.0 cm (measured as it is, not expanded), surface lubricous-waxy; stipe 4.0 - 6.2 cm long, diameter 2.8 - 7.8 mm, hollow, fibrous; taste not tested, smell indistinctive, on soil?
