REMARKS The most commonly found species of genus in the studied areas ( Fig. 9 A-D). The abundance of setae is highly variable among specimens, and often it is necessary to observe more than one microscopical preparation to detect their presence. The small pores (7-10/mm) and basidiospores (3-3.5 × 2-2.5 Μm), and the presence of setae in the dissepiments or immersed in the trama distinguish this species from other resupinate poroid Hymenochaetaceae in the region.
