 Description: Basidiocarp resupinate and effuse, ceraceous and separable, 160-370 μm thick in section. Hymenial surface white at the initiation of growth, Antimony Yellow to Warm Buff (Ridgway 1912) when mature, smooth, not cracked; margin often determinate and in such condition usually concolorous and rolls off from the substratum, occasionally filamentous and white. Hymenium composed of gelatinized, guttulate, longitudinally arranged basidial elements, ca. 120 μm thick. Subhymenium and medullary layer also with rather compact texture, but the latter looser near substratum. Hyphal system monomitic; subicular hyphae distinct, with clamps, 2-4 μm diam., with ± thickened walls or 0.4-1.2 μm thick. Cystidia lacking. Hyphidia- like elements distributed amongst other hymenium elements but difficult to distinguish clearly from the slender basidioles. Basidia long, clavate, flexuous, with tapering bases, 65-100 × 7.5-9 μm, bearing four stout sterigmata. Basidiospores cylindrical or narrowly ellipsoid, thin-walled, smooth, guttulate, 10-16 × 5-6.2 μm, IKI–, CB–.

 Note: The present specimen was collected from a trunk of a living Bischofia javanica. The basidiocarps grew under the bark and when the bark became shedded it appeared on the surface of the sapwood. The fruitbody observed during 1988 lasted for about one month then decayed after it rained for several days. The next year, a fruitbody of the same fungus appeared on the same location and vanished after one month, also due to continuous rain. The structure usually referred to hyphidia (J?lich & Stalpers 1980), in fact, cannot be clearly distinguished from the slender basidioles. Both are also guttulate. This structure thus differs, from typical concept of hyphidia, which are paraphysoid hyphae, different from basidioles; we consider them as young or aborted basidioles. This character should be regarded as important for classifying a species in the genus Cerocorticium P. Henn. The other important characters of this genus are clavate basidia with elongate bases, as well as large, and guttulate basidiospores.
