 Add this item to the list  PHELLINUS RIMOSUS (Berk.) Pil.
Page number:207 
Remarks (internal):As shown by Kotlaba and Pouzar (op.cit.) this species has had a variable interpretation and often the name P. badius has been used for it. We are still not convinced that the type of P. badius represents another taxon even if the tubes are more fragile than normal for P. rimosus. Its hyphal system, pores, and spores are identical with those of P. rimosus (see fig. 71 a).
Young specimens of P. rimosus may be confused with P. nilgheriensis, but this species usually has a tomentum when it is young even if it may wear away rapidly and leave a more or less evenly thick crust which does not become indurated and thickened to any considerable degree. Microscopically the two species may be separated by the smaller spores of P. nilgheriensis. Further, the pores of the latter are also smaller.

FRUITBODY pileate, perennial, solitary, mostly ungulate to triquetrous with a sloping pileus, semicircular and dimidiate with a contracted base, up to 12 cm wide and long 3-8 cm thick at the base, some specimens may even be larger, margin sharp to rounded, woody hard. PILEUS first more or less glabrous, except for a narrow marginal zone, fulvous to dark brown, smooth or with a few quite wide sulcate zones, somewhat warted or with irregular protuberances around the basal part, then the upper hyphae become indurated and black and the surface cracks up, both radially and along the sulcate zones and often in a tile-like way so very coarse black polygons of the surface become partly deflexed or bent upwards, finally the whole surface becomes cracked or creviced in black irregular polygons often with a greyish bloom on the top, along the margin there will often in such old specimens be a narrow more smooth and light-coloured zone reflecting new growth. PORE SURFACE yellow-brown in actively growing specimens and then pores thin-walled, in older specimens the pores become more occluded and more round and with thicker walls, (3)4-5 per mm, tubes fulvous brown, mostly distinctly stratified, up to 7 cm deep, rather easily setioned. CONTEXT rusty to snuff brown, radially fibrillose, but fairly dense and with a fine lustry shine when broken, 0.5-3 cm thick.
HYPHAL SYSTEM dimitic, generative hyphae variable, in the tubes 2.5-4.0 µm wide, yellow to pale rusty brown, simple septate and moderately-branched, in the context there are also some hyphae with distinctly thickened septa and with moderate branching, rusty brown and up to 7 µm wide and with a wide lumen, they must be classified as generative hyphae and are very similar to many hyphae in the context without any trace of septation. Skeletal hyphae 3-5 µm wide and almost solid in the trama, in the context somewhat wider but mixed with septate hyphae of the same kind, and it is difficult to be sure whether only one type of hyphae is present in the context i.e. variably skelerified generative hyphae with very scattered septa. In the material examined by us, it has been easier to differentiate the two types of hyphae in the trama than in the context. SETAE none. SPORES abundantly present, thick-walled, rusty brown, broadly ellipsoid to subglobose, 5.5-7 x 4.5-6 µm.
HABITAT. On deciduous wood, many collections have been made on trees from Fabaceae (in a wide sense), but also recorded from many other hosts, often in rather arid areas. DISTRIBUTION. Widespread in the old world from Southern Europe and throughout Africa, Asia and Australia.
