Description:

Lycogala epidendrum (L.) Fr.Wolf's Milk, Groening's Slime, DE: BlutmilchpilzSlo.: razbarvana grahovkaDat.: Nov. 9. 2017Lat.: 46.36014 Long.: 13.70435Code: Bot_1096/2017_DSC9621Picture file names: from Lycogala-epidendrum_raw_20 to Lycogala-epidendrum_raw_24.Habitat: mountain pasture; slightly inclined terrain, southeast aspect; colluvial/glacial, calcareous ground; full sun, dry place; elevation 575 m (1.900 feet); average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, alpine phytogeographical region. Substratum: a pile of partly rotten stump of Picea abies, mostly still in bark.Place: Lower Trenta valley, right bank of river Soa; between villages Soa and Trenta; near Trenta 2 farm house, East Julian Alps, Posoje, Slovenia EC.Comment: Average diameter of seven aethalia found was somewhat small (AVG = 4.5 mm, SD = 0.6 mm) compared to data from literature (the smallest had only 2.2 mm in diameter); however all other macroscopic traits fit well to Lycogala epidendrum species descriptions. Microscopically spore dimensions, their shape and reticulated surface, all fit to this species. Also pseudocapillitium diameter, its surface with conspicuous transverse faults and its club shaped free ends fit well. Spore mass grayish with pink tint. Spores reticulated, globose to subglobose. Dimensions: (6,7) 7 - 7,5 (7,9) x (6,5) 6,8 - 7,3 (7,5) microns; Q = 1 - 1,06 (1,1); N = 35; Me = 7,3 x 7,1 microns; Qe = 1.
