Description:ECHINOCHAETE RUFICEPS (Berk & Br.) Ryv.
Norw. J. Bot. 19(3-4):231, 1972 - Favolus ruficeps Berk. & Br., J. Linn. Soc. Bot. 14:57, 1873 (K:).
FRUITBODY annual, pileate, often several fruitbodies from the same point of attachment, 1-5 cm wide, 1-4 cm measured radially and 2-5(7) mm thick, thinning out towards the margin. consistency brittle to hard when dried. PILEUS varying in shape from dimidiate to flabelliform or spathulate with tapering base or with a distinct stipe, upper surface flat to convex, pale to dark reddish-brown, first minutely tomentose, when old smoother to rough with tomentum only near the stipe, sometimes radially striate. Margin deflexed when dry, even or lobed. STIPE reduced, 1 cm long, 0.2-0.5 cm wide, with decurrent pore-layer on the lower side, tomentose on the upper side. PORE SURFACE pinkish ochraceous to dark-brown, pores angular to hexagonal, 1-2 per mm, but often elongated radially towards the stipe, dissepiments thin, entire to weakly-incised, tubes up to 4 mm long, usually paler than the pore surface, but darker than the context. CONTEXT brittle to fibrous, 0.5-3 mm thick, straw to ochraceous, paler than the pore layer.
HYPHAL SYSTEM in the tubes dimitic, generative hyphae hyaline, thin-walled and clamped, 2.5-4 µm wide, binding hyphae golden, thick-walled to solid, 2.5-6 µm in diameter, sometimes looking as skeletal hyphae, but allways branched at the top if not broken, context hyphae dextrinoid especially when lying in clusters, hyaline to pale-yellow, weakly thick-walled, 2-11 µm wide. Pilear tomentum consists of yellowish, weakly thick-walled generative hyphae with great clamps and vegetative hyphae with secondary simple septa, up to 10 µm wide. SETOID ELEMENTS present in the hymenium, thick-walled and dark brown, up to 35-12 µm, ornamented with up to 9 µm long sharp spines. On the edge of the dissepiments the setoid elements are more hyphoid. On the pileus abundant and up to 90 µm long, brown, thick-walled and with occasional sharp lateral spines near the apex, some of them are without spines and some show secondary septation towards the tip. SPORES subcylindrical to ellipsoid, thin-walled, smooth and hyaline, 8.5-12(13.5) x 3.2-4 µm, non-amyloid.
HABITAT. On dead wood. DISTRIBUTION. Tropical parts of Africa (Kenya, Tanzania, Malawi, Uganda) and in Sri Lanka.
REMARKS. Macroscopic the species is close to E. brachyporus, but the former is often smaller and with a darker pilear surface due to the abundant dark setoid elements- in the pilear tomentum and cuticle.
