Basidia in irregularly scattered clusters visible as scattered white spots with the naked eye, not forming continuous basidiocarps. Hyphidia and cystidia absent. Hyphae hyaline, thin-walled, smooth, with simple clamps at the septa, 1.5-3 μm diam. Basidia aseptate, with basal clamps, obclavate, thin-walled, 38-65 μm long, 5-6 μm wide at the base, 2 μm wide at the apex, with four 1-2 μm long sterigmata, which in some cases appear refractive as seen by light microscopy. Basidiospores hyaline, thin-walled, smooth, ellipsoidal, inamyloid, 8-11.5 × 4.5-7 μm, inconspicuously apiculate. Anamorph absent. Structures and dimensions of basidia and basidiospores in fresh cultures on conifer twigs embedded in water agar identical to those found in situ. As seen by TEM, septa with dolipores with a channel occluded by plugs and associated with perforated parenthesomes.
Specimens：
Material was collected in Peitou, Taipei, Taiwan, R. Kirschner 535 and 811. Bark samples containing old insect tunnels (probably of bark beetles, Scolytidae, or weevils, Curculionidae) were peeled off from dead, standing trees of Pinus sp., taken to the laboratory, and the inner side of the bark was investigated with a dissecting microscope.

Note：
The morphological details of spores and basidia described above agree with those in the description of Rogersiomyces okefenokeensis by Crane and Schoknecht (1978). The informative illustrations and description by Matsushima and Matsushima (1996) allow adequate comparisons with R. okefenokeensis which appears to be nearly identical to H. malaysiana. Hyphobasidiofera malaysiana differs from R. okefenokeensis only by the larger basidiospores in the former species (11-15 × 8-10 μm, Matsushima and Matsushima, 1996). These two species should not be separated into two monotypic genera.
