Notes: Code: Bot_587/2012_DSC2154
Habitat: At the side of a group of Pinus nigra trees, south oriented mountain slope, fairly sunny and relatively warm place, calcareous ground, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 8-10 deg C, elevation 600 m (1.950 feet), alpine phytogeographical region.
Substratum: Dead stump of a cut down deciduous tree (possibly Ostrya carpinifolia) mostly still in bark and partly covered with mosses, also heavily infected with Trametes versicolor (as effuse-reflexed to pileate form), however fungus spread also to pieces of fallen off bark, herbaceous plant roots and old leaf petioles (as a resupinated form).
Place: Bovec basin, at the foot of Mt. Čukla, Ravni Laz place, above the dirt road to Plajerjeva skala, East Julian Alps, Posočje, Slovenia EC
Comments: Subglobose to ovate and significantly larger spores (see spore measurement chart), smaller diameter pseudocystidia, conical and longer than 1 mm aculei (see Ref.:(2)) distinguish this observation from more frequent Steccherinum ochraceum well. All forms from pure resupinated to distinctly pileate were present. Caps of pileate form zonate, up to 14 mm wide and 12 mm off the substrate, often confluent and up to 2 mm thick, context thin; upper side beige-pink with some brown strips and green (algae?), with thin whitish margin. Aculei up to 1.5 mm long, mostly conical, ocher-pink (oac764); hymenium in resupinated form with white edge. SP whitish.
