Mycena-epipterygia_4

Description:

Mycena epipterygia (Scop.: Fr.) Gray, syn.: Mycena viscosa Maire, Mycena citrinella (Pers.: Fr.) KummerYellowleg Bonnet, DE: Dehnbarer Helmling, berhuteter HelmlingSlo.: prevleena eladicaDat.: Oct. 22. 2015Lat.: 46.40463 Long.: 13.70942Code: Bot_922/2015_DSC9561Picture file names: from Mycena-epipterygia_raw_1 to Mycena-epipterygia_raw_6.Habitat: mixed wood, Picea abies and Fagus sylvatica dominant trees; among mosses, flat terrain, calcareous ground, moist place, in shade, partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 4-6 deg C, elevation 960 m (3.150 feet), alpine phytogeographical region.Substratum: soil, small, rotten branches, leaf and needles litter.Place: Zadnja Trenta valley, 50 m northwest of the final parking place of the access road to Zapodn place, East Julian Alps, Posoje, Slovenia EC Comments: There are hundreds of species and lower level taxa of genus Mycena described in the literature. The species of this genus are all but simple for determination. Taxonomy is not yet settled and is constantly changing. However, Mycena epipterygia is relatively easy to spot and recognized. It is a common fungus and its characteristic elastic and removable hut cutis and lightly yellowish (with green tint in this case) and like half translucent appearing stipe are reasonably reliable traits for an amateur determination. A good test is also as follows: after one breaks its hollow stipe into two parts, both parts remain connected with a rubbery, elastic cuticle. Nevertheless this species is highly variable in color, size, spore width and other characteristics. In this observation the mushrooms were growing scattered solitary and in small groups of a few fruit bodies, altogether 12-15 pilei on a few m2 of forest ground; pilei diameter 8 - 12 mm, stipe 5 - 8 cm long and 1 - 1.8 mm in diameter, stipe hollow and covered with a thin elastic cuticle like pilei; taste and smell unpleasant, weakly on soap?; SP too weak to enable reliable color determination, possibly whitish.Spores smooth.
