Type.

China. Yunnan: Hokin Delavay, no 1623 (Lectotype (designated here): G [G00061105/10811!]).

Remarks.

Calypogeia cordistipula   (Steph.) Steph was reported by Piippo (1990) for Chinese Yunnan (based on the type) but later synonymized with C. neesiana   ( Piippo et al. 1997). However, the two species are quite different. The differences from C. neesiana   include acute leaf apex, slightly larger cells, acute sinus in underleaves, absence of distinctly elongated cells along leaf margin, no pale coloration (in the present specimen, we suspect blue oil bodies because plants become somewhat blackish-grayish as is common for blue-oil-bodied taxa). We suggest that C. neesiana   does not occur in the Sino-Himalaya and that all records of that species may actually belong to C. cordistipula   .

The description based on the lectotype is as follows: plants greenish brownish to grayish brown, 1.5-2.1 mm wide, translucent, slightly glistening; stem ~2500 µm wide, branching not seen; rhizoids common, in brownish fascicles erect to upward obliquely spreading; leaves obliquely inserted, subhorizontally oriented, overlapping 1/2 of the next leaf in the base, loosely concave to almost planar, with apex slightly turned to dorsal side, not or for 1/3 of stem width decurrent, 800-1200 × 800-1200 µm, obliquely widely ovate-triangular, apex acute, never divided; underleaves appressed to the stem to obliquely spreading, 1.8-2.5 as wide as stem, decurrent for 1/2-2/3 of stem width, divided by U- to V-shaped sinus into two lobes without additional teeth, lobes obtuse, undivided portion 3-5 cells high; midleaf cells 40-50 × 40-68 µm, thin-walled, trigones small to very small, concave, cuticle virtually smooth.
