Bracket Fungi

Slo.: mehka skutovka - Habitat: Mixed wood, east inclined fairly steep mountain slope, calcareous ground, humid place, in shade, partly protected from direct rain by tree canopies, average precipitations ~ 3.000 mm/year, average temperature 6-8 deg C, elevation 640 m (2.100 feet), alpine phytogeographical region. - Substratum: large, approximately 70 cm (2.3 feet) in diameter, debarked fallen trunk of Picea abies in its late stage of disintegration. - Comments: This is an interesting fungus from several reasons. First it is quite rare. Second it is the only known species in the genus Leptoporus. Third it is a real surprise when you touch it - surprisingly spongy and so soft, that it is hard to handle it without damaging it. Indeed in strong contrast to what one expects from similar bracket fungi on wood. - Growing in groups, many fruit bodies present on the log; sessile brackets up to 5 cm wide, up to 2.5 cm off the substrate and about 2 cm thick, trama layer up to 12 mm thick, pore layer 5-7 mm thick, brackets partly fused; thickly effuse-reflexed form up to 5 x 3.5 cm, totally resupinated patches up to 20 x 6 cm; bruising reddish-brown when touched; taste distinctly aromatic-bitter; smell mushroomy, pleasant, lightly acid; flesh very soft like watery white cheese; no SP obtained, spores collected directly from pore surface using a soft brush; no hypha clamps observed; 5% KOH reaction on pore surface deep brown with red tint; the same on pileus, yet slower reaction and less intensive. Spores' width fits expectations; however, their length is somewhat too small. Probably they were not yet mature. - Spores smooth. Dimensions (only larger spores have been measured): 4.7 (SD= 0.2) x 1.8 (SD = 0.1) μ, Q = 2.62 (SD = 0.23), n = 21. Olympus CH20, NEA 100x/1.25, magnification 1.000 x, oil, in water.

Slo.: pisana ploskocevka - Habitat: Young, mixed forest and bushes, Fagus sylvatica, Picea abies, Ailanthus altissima, Fraxinus ornus, Ostrya carpinifolia, Corylus avellana dominant; overgrown former pasture; slightly inclined mountain slope, south aspect; shallow, skeletal, calcareous ground; relatively warm place; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 610 m (2.000 feet), alpine phytogeographical region.Substratum: dead, still standing Fagus sylvatica trunkComments: Trametes versicolor is a very common species. Several authors consider it as the most frequent decomposer of wood of deciduous trees. It almost always appears in large, sometimes very beautifully colored, colonies. But it is also a very variable species, particularly in colors of distinctly zonate pilei. Because of that confusion with other species of genus Trametes is quite possible. The best distinguishing traits of Trametes versicolor for me are very small pores (up to 5/mm) and a distinctive, but very thin dark brown line between context and tomentum in cross-section. But one should cut pilei with a very sharp knife, or better with a razor blade. In this way the line remains undamaged and clearly visible. Growing in a group of several hundreds of pilei; pilei dimensions up to 4.6 x 2.9 cm and up to 6(8) mm thick, pore layer 1.5(2.5) mm thick; taste distinct, unpleasant, on rotten something?; smell mild, mushroomy; pore density 43/cm (SD=5.3, n=8), SP whitish-beige, oac 851.Spores smooth.

Substratum: dead, still standing Fagus sylvatica trunk Comments: Trametes versicolor is a very common species. Several authors consider it as the most frequent decomposer of wood of deciduous trees. It almost always appears in large, sometimes very beautifully colored, colonies. But it is also a very variable species, particularly in colors of distinctly zonate pilei. Because of that confusion with other species of genus Trametes is quite possible. The best distinguishing traits of Trametes versicolor for me are very small pores (up to 5/mm) and a distinctive, but very thin dark brown line between context and tomentum in cross-section.

Slo.: pisana ploskocevka - Habitat: Young, mixed forest and bushes, Fagus sylvatica, Picea abies, Ailanthus altissima, Fraxinus ornus, Ostrya carpinifolia, Corylus avellana dominant; overgrown former pasture; slightly inclined mountain slope, south aspect; shallow, skeletal, calcareous ground; relatively warm place; partly protected from direct rain by tree canopies; average precipitations ~ 3.000 mm/year, average temperature 7-9 deg C, elevation 610 m (2.000 feet), alpine phytogeographical region. Substratum: dead, still standing Fagus sylvatica trunk Comments: Trametes versicolor is a very common species. Several authors consider it as the most frequent decomposer of wood of deciduous trees. It almost always appears in large, sometimes very beautifully colored, colonies. But it is also a very variable species, particularly in colors of distinctly zonate pilei. Because of that confusion with other species of genus Trametes is quite possible. The best distinguishing traits of Trametes versicolor for me are very small pores (up to 5/mm) and a distinctive, but very thin dark brown line between context and tomentum in cross-section.
