_Stereodon (vel Hypnum) crassicostatus Kindb. n. sp. 
Differs from Hypnum Lindbergii (Stereodon arcuatus Lindb.) : 
leaves long-deccurent, not densely crowded, insertion always pale; 
alar cells large, often inflated and suboval; costa thick, often rea- 
ching to the middle, cleft below into two, mostly inequally long 
branches. The leaves are bright green, much curved ; paraphyllia 
large, broad, acuminate and entire. Only male plants seen.
