Vrsnik valley, above the settlement Na skali, East Julian Alps, Posočje, Slovenia EU. (Posočje, Slovenia)notes Syn.: Lycogala epidendrum var. terrestre (Fr.) Y. Yamam - Habitat: Open wood, Picea abies and Fagus sylvatica dominant trees; steep mountain slope; southeast aspect; calcareous ground; rather dry place, in half shade; exposed to direct rain; temperatures during last few days from -5 to 5 deg C; average precipitation ~ 3.000 mm/year, average temperature 4-6 deg C, elevation 1.165 m (3.800 feet), alpine phytogeographical region. Substratum: rotten stump of a large Picea abies overgrown with mosses. Comment: Distinctly pink spore mass of mature aethalia and flexible pseudocapillitium threads distinguish this find from Lycogala epidendrum (L.) Fries (gray spore mass and fragile threads) and determine it as Lycogala terrestre Fries. (Ref.: 1 and 5). However, not all authors recognize both taxa. Some consider Lycogala terrestre as variety of Lycogala epidendrum, some synonimyze them (Ref.4). What surprises with this find is unusual surface of spores. Almost all sources state minutely reticulated spores for both Lycogala epidendrum and Lycogala terrestre, while the spores observed show quite coarse reticulation. Also aethalia show both, almost smooth, minutely spinulose, as well as coarsely, transversally wrinkled surface of pseudocapillitium threads. About 12-13 aethalia found. Average diameter 6.7 mm, SD = 1.7 mm (min = 3.5 mm, max = 9.2 mm). Peridium thin but strong, flexible. Pseudocapillitium threads flexible. Spores minutely warty, globose to subglobose. Dimensions: 6,5 [6,9 ; 7] 7,5 x 6,3 [6,7 ; 6,8] 7,2 microns; Q = 1 [1,0] 1,1; N = 42; C = 95%; Me = 7 x 6,7 microns; Qe = 1.
