Habitat: South inclined mountain slope, mostly broadleaf forest, calcareous ground, quite humid but warm place, mostly in shade, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C,
elevation 505 m (1.650 feet), alpine phytogeographical region.
Substratum: dead trunk of a cut off broadleaf tree, lying on ground, quite rotten but still mostly in bark. On the same log also Fomitopsis pinicola.
Place: Bovec basin, at the foot of Mt. Čukla, below Ravni laz place, East Julian Alps, Posočje, Slovenia EC
Comments: According to Ref.:(2) S. subtomentostum has no acanthohyphydia in the hymenium while similar S. ostrea has them (Ref.:(2), p335 and key on p.356). I was unable to find them in spite of the fact that they should be quite large (>100 x 5-10 micr. Ref.:(1)). There was no bleeding observed probably because of fairly dry state of the fruitbodies and weather. Average day temperatures about 0 deg C with -5 degC during the night.
Pileus dimensions up to 9 × 5 cm (3.5 × 2 inch), 1 mm or less thick. Smell indistinctive. Cup upper surface rusty-red-brown (oac700), hymenium dull brown-red (oac700), trama of wood color, with thin (~ 0,1 mm) brown upper layer and about 0.4 mm thick hymenial layer.
Spore dimensions: 6.6 (SD = 0.6) x 2.6 (SD = 0.2) micr., Q = 2.58 (SD = 0.2), n = 30. Motic B2-211A, magnification 1.000 x, oil, in water. Congo red.
