FRUITBODY annual to perennial, sessile or with a short stipelike base, attached laterally or centrally, pileus 1-35 cm wide and long and 0.2-3 cm thick, corky and flexible when fresh, more rigid when dry. PILEUS flabelliform or circular, upper surface white to grey or almost buff ochraceous in older specimens, surface very finely tomentose, soon glabrous, smooth or concentrically sulcate, often warted or with slightly uneven elevated areas. Margin thin and often deflexed, even or lobed. STIPE absent or up to 3 cm long, 1.5 cm in diameter, glabrous, solid, attached to the substrate with a disc up to 3 cm wide, concolorous with pileus surface, mostly white to pale cream. PORE SURFACE very variable, partly poroid, round to angular, 1-2 per mm, partly sinuous-daedaloid and radially split, up to 2 mm wide, partly purely lamellate with straight to sinuous lameleae, 4-7 per cm measured tangentially. This variation may occur in a single specimen. Even in poroid specimens some parts the hymenophore will usually have a few lamellae or sinuous pores. Pores or lamellae up to 6 mm deep. CONTEXT white to pale cream, up to 15 mm thick near the base, woody hard when dry.
HYPHAL SYSTEM trimitic, generative hyphae hyaline, thinwalled and clamped, 2-4 µm wide, not always easy to find in dried specimens. Skeletal hyphae dominating, yellow to golden and thick-walled to solid, 3-7 µm in diameter, binding hyphae hyaline to pale yellow thick-walled, up to 5 µm wide, irregular branched. CYSTIDIA as such not present but binding hyphae project into the hymenium and may easily be interpreted as acute cystidia until a section is squeezed and their true nature is revealed. SPORES cylindric to oblong ellipsoid, hyaline, smooth and thin-walled, 5-7 × 2-3 µm, non-amyloid.
HABITAT. On dead deciduous wood of all kinds.
DISTRIBUTION. Pantropical and very common in areas with seasonal drought where the fruitbodies survive from one season to another. In East Africa known from Ethiopia to Malawi.
REMARKS. The species is easy to recognize because of the narrow lamellae or sinuous pores and the frequenty variable hymenophore on the same specimens. From L. vespacea it is separated by small pores and a smooth pileus which is finely asperulate in L. vespacea. It may be confused with old specimens of Cerrena meyenii which, however, is harder, more yellowish on the pore surface and has a dark line between the upper tomentum and the lower context. However, the dark line may be weakly developed and it is necessary to take a section close to the base to verify its presence.
