Remarks (internal):Gloiothele Bres. was introduced by Hjortstam (1987) to accommodate those species without clamp-connexions and with smooth, slightly amyloid spores which were formerly placed in Gloeocystidiellum Donk. All species have gloeocystidia which exhibit a more or less strong sulphovanillin reaction. Among them, G. lactescens (Berk.) Hjortst. and G. lamellosa (P. Henn.) Bres. (generic type) are well known. The former is a rather common north temperate species, whereas the latter is a tropical species, known only from Africa.
Gloiothele granulosa is microscopically similar to the generic type and differs mainly in having smaller spores and a denser hyphal texture. The hymenium of G. lamellosa is distinctly odontioid to irpicoid whilst that of all other species is more or less smooth.

Description:Gloiothele granulosa Hjortst. & Spooner, sp. nov. (Fig. 1 A-E).
Basidiome resupinate, cfosely adnate, c. 0.25-0.40 mm thick. Hymenium at first ± smooth, becoming granulose but not distinctly tuberculate or odontioid, in colour pale brown with a reddish tint (Munsell ± 8.5YR 5.5/2.8). Hyphal system monomitic; basal hyphae moderately thick-walled, hyaline to more commonly pale yellowish brown, slightly dextrinoid (usually after 1-2 minutes), 3.0-3.5(-4.0) µm, some hyphae narrower, 1.5-2.0 µm, while most of the subhymenial hyphae are thin-walled, measuring 2.5-3.5 µm diam.; all hyphae without clamp-connexions. Sulphocystidia numerous, tubular, thin-walled, rather straight, subulate, 100-160 µm long x 8-9 µm wide in the middle part. Basidia clavate, when fully developed slender, sinuous and/or constricted, 25-30 x 4.0-4.5 µm, with four sterigmata and without a basal clamp-connexion. Spores subglobose, thin-walled, smooth, hyaline, 4.0-4.5(-5.0) x 3.5-4.0(-4.5) µm, amyloid, although this reaction is often rather weak.
Typus: Malaysia, Sabah, Danum Valley, on standing dead tree, 28 Nov. 1985, B. M. Spooner 248 (holotypus K).
