Tremella taiwanensis C.-J. Chen, Bibliotheca Mycologica 174: 1-225. 1998.

 Description: Basidiocarps pulvinate to cerebriform, whitish yellow, hollow, 0.5-1.7 cm ø, dry light yellow, flat on the substrate. Basidia ±subglobose to ellipsoid, (21-)23-29(-31) × (20-)22-27 μm [Q=0.91-1.20(-1.45)], longitudinally or obliquely cruciate-septate, mostly 4-, occasionally 2-spored; sterigmata up to 120 μm in length, 5-8 μm ø, sometimes apically swollen up to 10 μm ø; infrequently producing conidia directly from basidia or sterigmata. Spores ±globose to subglobose, (12-)14-18 × (12-)14-20 μm [Q=0.86-1.15]; mostly broader than long, hyaline, smooth; germinating by budding. Conidia monokaryotic, mostly subglobose to ellipsoid, 6-9(-11) × 5-7 μm [Q=(1.00-)1.09-1.55(-2.00)], hyaline, smooth, thin-walled; often budding from apex of sterigmata, sometimes from the side of sterigmata or basidia, occasionally directly from basidia instead of sterigmata. Vesicles absent. Swollen cells absent. Hyphidia rare, 2-3(-4) μm ø, thin-walled. Hyphae smooth, hyaline, 2-4(-5) μm ø, sometimes slightly swollen. Haustoria clamped; very rare, growing out from hyphal clamps.

 Note: The whitish yellow basidiocarps are easily to be associated with Mesenterica group, and their basidia in big size are close to T. brasiliensis but distinct from measurements. Tremella taiwanensis has loose hymenial structures, large basidia and big sized of basidiospores. The conidia are produced from the side or the top of sterigmata, or even the side of basidia. Sometimes the basidia produce conidia directly from the position of sterigmata. Those conidial characters can be found also in T. globospora, however T. taiwanensis differs from them in distinct substrate, basidiocarps, size and shape of the basidia and the basidiospores.
