location
Lower Trenta valley, between villages Soča and Trenta, right bank of river Soča, near 'Na melu' place, East Julian Alps (Posočje, Slovenia)notes Slo.: žametna podvihanka - syn.: Paxillus atrotomentosus (Batsch.) Fries - Habitat: mixed wood, Picea abies and Fagus sylvatica dominant; moderately southeast inclined foot of a mountain; rather dry place, in shade; shallow, skeletal, calcareous ground, old overgrown scree slope; partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 630 m (2.070 feet), alpine phytogeographical region. - Substratum: Picea abies stump in its final stage of disintegration. - Comments: Tapinella atrotomentosa is a cosmopolitan, relatively common species. Yet it is not frequently seen in my region. It is a striking, interesting mushroom with its large, mostly dark brown, velvety pileus and primarily by its thick, almost black and coarsely velvety stipe. Latin word 'atrotomentosus' translates to 'black-haired'. Nothing similar exists in our woods, therefore determination isn't difficult. - In this observation it was growing solitary; pileus dimensions 16 x 12 cm, stipe 5 cm long and 3 cm thick; taste mildly mushroomy; smell mild, mushroomy, slightly on a perfume; flesh thick, brittle; SP light-ocher, oac814. - Spores smooth. Dimensions: 4,4 [5,6 ; 6] 7,2 x 3,3 [3,7 ; 3,8] 4,2 microns, Q = 1,3 [1,5 ; 1,6] 1,7; N = 42; C = 95%, Me = 5,8 x 3,8 microns; Qe = 1,5.
