Description:POLYPORUS DIABOLICUS Berk.
Hook. Lond. J. Bot. 8:174, 1856 (K!). - Polyporus_ vernicosus Berk. ibid. 175, 1856 (K:).
FRUITBODY more or less as for P. dictyopus or P. blanchettianus, but the stipe is almost 9 cm long in the type, thus longer than normally found in the mentioned species, it is black and smooth. PORE SURFACE dark brown today in the type, pores are tiny, 7-8 per mm, tubes dark brown, up to 4 mm deep. CONTEXT pale cinnamon, woody to corky, up to 4 mm thick.
HYPHAL SYSTEM dimitic, generative hyphae with clamps, 1- i 3 µm wide, binding hyphae of the Bovista-type present, strongly branched, up to 8 µm wide in the main trunk, also present are very widened segments of binding hyphae, 15-80 µm long, up to 15 µm wide and with short and narrow branches or short tuberances at the apex, partly projecting into the collapsed hymenium, present are also some less widened segments with thickened walls and distinct lumen reminding of those found in P. blanchettianus. SPORES not seen.
HABITAT and DISTRIBUTION. On deciduous wood, known only from Guyana, but will probably be found throughout the Amazonian basin.
REMARKS. The species is close to P. infernalis and P. blanchettianus and it is a question whether the different types of widened segments seen in these species actually are only variations of the same characteristic.
