FRUITBODY annual, pileate, sessile, single or laterally fused or connate and elongated, frequently with decurrent pore layer, up to 4 cm wide and 15 cm long in fused fruitbodies, the resupinate pore layer widely effused for several dm in some cases, up to 1 cm thick at the base, margin entire, crenulate, lobed or dentate, undulating and sharp. PILEUS ochraceous to deep hazel brown frequently greyish brown, hirsute to tomentose, even hispid at the base as the tomentum may become agglutinated to erect protuberances, but in some specimens also more or less flattened to an adpressed tomentum, but usually somewhat scrupose in old specimens, distinctly to indistinctly zonate, often in rather broad zones, 1-5 mm wide, also somewhat radially striate. PORE SURFACE greyish-brown with a distinct bluish ashy grey tint which is typical for this species, in old specimens more tobacco to greyish-brown, pores round to angular, entire 2-4(5) per mm in old specimens and on the decurrent pore layer frequently larger and elongated radially, up to 1-2 mm long, but these pores only occur scattered, old fruitbodies may become dentate and split in the pore surface, tubes concolourous with the pore surface in the tube walls, in the trama dark brown, thus the trama and the tube walls are contrasting, up to 6 mm deep in thick specimens. CONTEXT distinctly duplex, lower part dense, tobacco-brown and shiny fibrous when sectioned, up to 4 mm thick, upper part looser and floccose, more greyish-brown, in some specimens the two parts are separated by a thin black line, which however is rather irregular and frequently absent, trama and context black with KOH.
HYPHAL SYSTEM trimitic, generative hyphae hyaline, thinwalled and with clamps 1.5-4 µm in diameter, often collapsed and distorted in preparations, skeletal hyphae abundant, yellow to almost golden, thick-walled, 3-8 µm wide, in the context lighter and more thin-walled. Binding hyphae thinwalled to slightly thick-walled 1.5-4 µm, hyaline to yellowish, irregular in outline, with numerous relatively short tapering branches. SPORES cylindrical, hyaline, smooth and thin-walled, non-amyloid, 8-11(14) x 2,5-4(5) µm, usually varying within the same collection. CHLAYMODOSPORES observed in the context of one specimen from Ghana, Kumasi, March 1972 leg. A. Ofosu-Asiedu (0), globose, thick-walled yellowish-brown, 5-7 µm in diameter. Not seen in other specimens.
HABITAT. On angiosperms of all kinds. DISTRIBUTION. Pantropical and rather common in East Africa in savanna-land and dry forests.
REMARKS. This is a variable species, and as indicated above, described many times due to this variability. The pileus surface may be soft tomentose to hispid without zones, to distinctly zoned with a variable type of tomentum from zone to zone. However, usually the pileus is greyish brown, but also more pure umber to hazel. The pore surface is in most cases very typical with its greyish to bluish ashy tints also coloring the inner tubes. It is the only species of the Coriolopsis species described here, that has these characteristics.
C. floccosa is undoubtedly closely related to C. gallic of Europe which has the same type of pileus variability and frequently the same ashy-bluish colour pore surface. However, in C. gallic the pores are larger and the fruitbody thicker. However, we have seen specimens from Iran that are quite intermediate.
