Description:

Micromphale perforans, syn.: Marasmiellus perforans (Hoffmann 1783) Fries 1821, Marasmius abietis (Batsch 1783) Quelet 1888Stinking Parachute, DE: NadelschwindlingSlo.: iglina sehlevkaDat.: Oct. 15. 2013Lat.: 46.36030 Long.: 13.70293Code: Bot_761/2013_DSC8668Habitat: under Picea abies growing on an abandoned pasture already partly overgrown with individual trees, locally flat terrain, calcareous ground, in full shade, partly protected from direct rain by tree canopy, average precipitations ~ 3.000 mm/year, average temperature 7-9 C, elevation 600 m (1.950 feet), alpine phytogeographical region.Substratum: fallen off needles of Picea abies in moos layer.Place: Lower Trenta valley, between villages Soa and Trenta, southeast of 'Na melu' place, East Julian Alps, Posoje, Slovenia EC.Comments: This is a common species in Trenta valley. When the time, temperature and humidity are appropriate these tiny mushrooms sometimes explode in an unimaginable number. Hundreds upon hundreds grow almost under every Picea abies tree in the mixed forest. Pity, they are not larger and edible ;-)Growing in a large group under the canopy of a large Picea abies tree. Pilei diameter from 5 to 8 (10) mm; stipe thin, about 0.6 mm in diameter and max 3 cm tall; smell unpleasant, taste mild, specific but I don't know on what; SP abundant, whitish-crme, oac900. Measured spores seem too large when compared to data from literature, however, even the literature written by prominent authors states surprisingly different dimensions in spite of the fact that this is a common species.Spores smooth. Measured dimensions: 7,9 [9 ; 9,3] 10,3 x 2,6 [3,9 ; 4,4] 5,7 microns, Q = 1,8 [2,2 ; 2,3] 2,7; N = 41; C = 95%. Me = 9.1 x 4.2 microns; Qe = 2,2.
