Description:TRAMETES PUBESCENS (Fr.) Pil.
Atlas Champ. Europ. 3:268, 1939. - Polyporus pubescens Fr. Syst. Mycol. 1:368, 1821 (UPS:).
FRUITBODY annual, pileate, solitary or in groups, applanate to dimidiate up to 7 cm wide, 10 cm long and 3-15 mm thick at the base, rather soft and sappy when fresh, light in weight and fairly brittle when dry. PILEUS creamish, pale straw-coloured to yellowish tan, in African specimens usually of even colour, but a few darker zones may develop with age, azonate or weakly zonate, first finely pubescent then becoming more glabrous and in older specimens there is a thin distinct adpressed layer of agglutinated hyphae, in Africa it is fairly unusual to see brown radial fibers which are more common in European specimens. PORE SURFACE cream to pale straw-coloured, pore thin-walled and angular somewhat dentate in older specimens with lower crosswalls inside larger and more sinuous pores, most pores 2-4 per mm, but some larger may also occur, tubes concolorous, up to 5 mm deep. CONTEXT white, dense in the lower part, slightly looser towards the pileus but no borderline visible between the finely adpressed tomentum and context and the latter is strictly homogeneous.
HYPHAL SYSTEM trimitic, generative hyphae thin-walled, hyaline and with clamps, 2-4.5 µm wide, skeletal hyphae thick-walled, hyaline, in the pileus tomentum with a wide lumen, 3-8(10) µm wide, in the lower context distinctly more thick-walled, binding hyphae common in the lower context and trama, strongly tortuous and intertwined and difficult to spread in preparations, partly occurring as balls of coarse yarn, branching difficult to elucidate, mostly 2-4 µm wide. SPORES cylindrical to allantoid, smooth, thin-walled, hyaline and non-amyloid, 5-7 x 1.5-2.5 µm (measured from spore print), they are seemingly somewhat wider (mostly 22.5 µm) in thick-fleshed specimens and thinner in the thin flabelliform specimens (1.7-2.2 µm).
HABITAT. On deciduous wood of all kinds. DISTRIBUTION. Cosmopolitan species, widespread in East Africa and we have seen specimens from Ethiopia, Kenya and Tanzania.
REMARKS. The species is recognized by its cream to straw-coloured colours, its lightweight fruitbodies and the thin-walled, angular pores. The African specimens seem to become more glabrous and smooth than those in Northern Europe. Otherwise there is no difference either with regard to macromorphology or to microscopical characteristics.
