Helicogloea musaispora C. J. Chen & Oberwinkler, Mycotaxon 76: 279-285. 1998.
Description：
Basidiocarps corticioid, mucous-gelatinous, very thin, ca. 30-50 µm in thickness, hyaline, whitish, dry becoming hyaline, inconspicuous film. Basidia with short stalks, probasidia thin-walled, mostly 13-16 × 4.5-6 µm; metabasidia 55-70 × 4.5-6.5 µm, 4-spored; sterig-mata short, 1-2 µm in length; sacks 17-26 × 8-10 µm, thin-walled; frequently branched mycelia bear many sacs and probasidia. Basidiospores navicular, typically banana-like bend towards the apiculus (bananiform), 18-22 × 4-5 µm, germinating by repetition, the secondary spores have the same shape, hyaline, thin-walled. Hyphae without clamp connections. Usually generative hyphae close to bark are thin-walled apically to slightly thick-walled when mature, swollen irregularly, 7-12 µm in diameter. Haustoria not detected.

Note：
The cylindrical basidiospores in the genus Helicogloea are rarely investigated. The new species separates from all previously described members of Helicogloea in its banani-form basidiospores and measurements. Two known species, H. longispora Baker (Baker, 1946) and H. augustispora Olive (Olive, 1951), are considered to be closely related. Nevertheless, H. musaispora differs from H. augustispora in distinctive measurements of hyphae and basidia. Furthermore, it is separated from H. longispora according to the basidiospores considerably larger than those of H. longispora. The bananiform basidiospores in Helicogloea are investigated only appearing in H. musaispora. However, such bananiform basdiospores had also been examined in Botryobasidium bananisporum Boidin (Boidin, 1970) and B. musaisporum G. Langer (Langer et al., 2000).
