Description:PHELLINUS FERRUGINOSUS (Fr.) Pat.
Ess. tax. p. 97, 1900. - Polyporus ferruginosus Fr. Syst. mycol. 1:378, 1821.
FRUITBODY annual to perennial, resupinate, adnate, mostly widely effused nodulose along the margin, up to 60-70 cm long, 4-15 cm wide, up to 12 mm thick in old specimens, coriaceous and flexible. PORE SURFACE even to nodulose or slightly undulating, fulvous to umber brown, margin in actively growing specimens floccose, yellowish-brown, narrow to wide, on irregular substrates cottony and filling cavities in the substrate, pores usually 5-6 per mm, round and entire on horizontal parts, split on oblique parts of the fruitbodies, tubes concolorous with the pore surface, weakly stratified in old and thick specimens, 1-3 mm in each layer, totally up to 10 mm deep on oblique parts. CONTEXT cinnamon to rusty brown, rather loose and cottony, distinct and of irregular thickness, filling cavities in the substrate, up to 4-5 mm in places.
HYPHAL SYSTEM dimitic, generative hyphae hyaline, simple septate and 2-4 µm wide, skeletal hyphae thick-walled, rusty brown to yellow in KOH, with a distinct lumen, straight, 35.5 µm wide, more or less parallel in the trama, randomly orientated in the subiculum. SETAL HYPHAE present in the margin and cottony subiculum, straight, dark brown and thick-walled, 5.5-12 µm wide, up to 300 µm long, usually easy to observe. HYMENIAL SETAE numerous, subulate, thick-walled and rusty brown, usually with a somewhat elongated base which often has a lateral swelling, (20)25-55(60) x 68.5 µm, TRAMAL SETAE (or short setal hyphae) scattered to rare, embedded in the trama and parallel with the tubes, 30120 x 5-8 µm, often difficult to observe. SPORES broadly ellipsoid, hyaline, thin-walled and non-amyloid and indextrinoid, 4-6 x 3-3.5 µm.
HABITAT. On deciduous wood. DISTRIBUTION. Mainly a European species, but also found several times in East Africa.
REMARKS. The species is easy to recognize due to the setal skeletal hyphae in the margin, numerous hymenial setae and the spores which are shorter than those of P. contiguus.
