general taxon notes:

Bryonoguchia contains 2 species in the world, commonly on rock surfaces, humus, decaying logs or tree trunks in high altitude forests. Bryonoguchia molkenboeri (Sande Lac.) Iwats. & Inoue was first reported from northeastern China as Tetracladium molkenboeri (Sande Lac.) Fleisch. (C. Gao et al. 1977). C. Gao and G.-C. Zhang (1982) published the genus, Bryochenea with B. ciliata as its type species and included another species, B. sachalinensis. Most recently, P.-C. Wu and Y. Jia (2000) reduced Bryochenea ciliata to synonymy of Bryonoguchia molkenboeri and transferred Bryochenea sachalinensis to Helodium. The genus Bryochenea, therefore, is treated as a synonym of Bryonoguchia. In this study, we recognize two species, Bryonoguchia molkenboeri and a recently published new species B. brevifolia S.-Y. Zeng (S.-Y. Zeng 1991).

Setae reddish brown to yellowish brown, 3–5 cm long, smooth; capsules cylindrical, horizontal, reddish brown to yellowish brown, 3–4 mm long; opercula conic; exostome teeth lanceolate 0.5–0.6 mm long, yellowish brown to reddish brown, trabeculate at base, finely papillose above; endostome segments yellowish brown, as long as the teeth; membrane 1/2 the segment height, minutely papillose; cilia hyaline, 2–3.
