Type.
Japan. Mt. Yokogura, May 1901, T. Yoshinaga no. 38 (LECTOTYPE (designated here): G [G00067733!], another, poor specimen [G00282608!] is lectotype duplicate. This species was founded on the gatherings by T. Yoshinaga and U. Faurie, however only
Yoshinaga's
collections are now present in G. Both reviewed specimens contain plants fully corresponding to the original description).
Remarks.
Hattori (1966)
synonymized this species with
Calypogeia tosana
, regarding
C. yoshinagana
as only an environmentally induced modification. We, however, believe these are separate species.
Calypogeia yoshinagana
differs from
C. tosana
in acute leaves (very rarely bidentate and, if bidentate, the
'lobes'
are distinctly unequal), more or less rigid texture, dull coloration (plants are not glistening). Attention to this species is needed in the eastern Meta-Himalayan flora where it may be revealed.
The description based on the lectotype is as follows: plants greenish brownish to dirty greenish, 1.8-2.2 mm wide, 2-3 cm long, relatively rigid; stem 200-250
µm
wide, branching not seen; rhizoids sparse to common, in brownish, erect spreading fascicles; leaves obliquely inserted and oriented, slightly concave-canaliculate, leaves not decurrent ventrally, triangular-ovate, with acute or rarely obtuse or bidentate apices, 900-1100

; underleaves 1.5-2.5 as wide as stem, decurrent for 1/3-2/3 of stem width, clearly bisbifid, undivided area 2(-3) cells high; midleaf cells subisodiametric 30-50
