Dead wood and mycoflora in Nature Reserve Polom, Protected Landscape Area ?elezné hory

摘要

Activity of fungi participating in the dead wood decomposition was studied in the Velky Polom Nature Reserve, Protected Landscape Area ?elezné hory. Two game-proof fences of an area of 0.30 ha (570 m alt.) and 0.19 ha (620 m alt.) were used as permanent sample plots. In both the plots, activities were monitored of wood-destroying fungi in 126.82 m³ dead wood, 104.05 m³ of which were in beech. After conversion to an area, the volume amounts to 258.82 m³ per ha. In the whole reserve, almost 220 species of macromycetes were recorded in the course of a mycological survey. Wood-destroying fungi are the dominant component of mycoflora representing more than 50% identified taxa of in the period under study. The proportion of mycorrhizal fungi amounted to 14%. A series of macromycetes considered to be saprophytes is bound to products of wood decomposition. Fomes fomentarius (L.) Fr., Fomitopsis pinicola (Sowerby) P. Karst., Ustulina deusta (Fr.) Petrak, Hypoxylon fragiforme (Pers.) Kickx, Ganoderma lipsiense (Batsch) Atk. and the genus Armillaria were the predominant species of wood-decaying fungi. As for rare macro-fungi, it is possible to mention Ascotremella faginea (Peck) Seaver, Stropharia albocrenulata (Peck) Kreisel and Tricholomopsis decora (Fr.) Singer.
