Mycena meliigena (Berk. & Cooke) Sacc., syn.: Mycena corticola (Pers.) Fr.DE: Rtlicher Rindenhelmling, Fleischroter HelmlingSlo.: lubjeva eladicaDat.: March 25. 2017Lat.: 46.33514 Long.: 13.56886Code: Bot_1042/2017_DSC7146Hypha with characteristic digitiform outgrowths. Habitat: mixed broadleaved and conifer wood, locally almost flat terrain, cretaceous clastic rock (flysh) bedrock, in shade; dry place, partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 470 m (1.550 feet), alpine phytogeographical region.Substratum: still standing Alnus sp. bark lightly overgrown with mosses; on northeast side of the trunk.Place: Bovec basin, east of Bovec, Rabeljnik hill, East Julian Alps, Posoje, Slovenia EC. Comments: This incredible small and filigree mushroom is, no doubt, frequently overlooked. Tiny, only a few millimeters tall, more or less brown on more or less brown, cracked tree bark, it hides itself perfectly. However, looked from close the impression is much different. Its size, unusual hyphal ends of the cortical layer of the stipe and hypha with strange digitiform outgrowths distinguish it from other small Mycena species. Growing in a group of a few fruit bodies, pileus diameter 2 to 4 mm, SP very faint, almost invisible, probably whitish.Spores smooth. Dimensions: 8,1 [9,1 ; 9,6] 10,5 x 7,3 [8 ; 8,4] 9,1 microns; Q = 1 [1,1 ; 1,2] 1,3; N = 26; C = 95%; Me = 9,3 x 8,2 microns; Qe = 1,1.
