Remarks (internal):Vesiculomyces globosporus is similar to V. citrinus (Pers.) Hagström (Hag­ström, 1977), V. lactescens (Berk.) Boidin & Lanquetin (Eriksson and Ryvarden, 1975) and G. tropicalis Burdsall, Nakasone & Freeman (Burdsall et al., 1981). However, V. globosporus is distinguished from the related species by the following combination of characteristics: basidiomata with pruinose margin, narrowly clavate basidia measuring 33-45 x 7.5-9.5 µm, and larger subglobose to globose basidiospores, 7.5-10.5x 7-9.5 µm. This species is associated with a white rot of its wood substrates.

Description:Vesiculomyces globosporus Maekawa, sp. nov. (Fig. 21)
Holotype: TMI-12769 (TMI) on decaying wood of a broad-leaved tree, Saroma-cho, Tokoro-gun, Hokkaido, 27 Sept. 1984.
Basidiomata resupinate, adnate, effused, 100-200 µm thick; hymenial surface "Buff" to "Pale Luteous", smooth, ceraceous; margin white to "Buff", thinning out, pruinose under the lens (x 20). In vertical section, subhyaline, membranous. Hyphal system monomitic; hyphae 1.5-3 µm in diam, smooth, thin-walled, clampless-septate; cystidia (gloeocystidia) numerous, cylindrical, sinuous, without a basal clamp, 70-120 x 7-9.5 µm, smooth, thin-walled, sometimes slightly projecting beyond the hymenial surface, positive to sulphoben­zaldehyde; basidia narrowly clavate, without a basal clamp, 33-45 x 7.5-9.5 µm, producing 4 sterigmata; basidiospores subglobose to globose, with a distinct apiculus, 7.5-10.5 x 7-9.5 µm, smooth, thin-walled, amyloid.
