440 CoKER: NortH AMERICAN SPECIES OF ENCALYPTA 
According to Limpricht (39, p. 115. f. 245, 246) there is great 
variation in the peristomes of this species. However, we have not 
found any peristome to correspond with his f. 246 in American 
specimens. 
TYPE LOCALITY: European. 
DistrIBUTION: Arctic America, Greenland, Labrador to 
Quebec and northern New York, Rocky Mountains from Mon- 
tana to New Mexico, Pacific Coast ranges from Washington to 
California. Also Europe and Asia.

E. leiomitra differs from E. rhabdocarpa only in that the apex 
of the calyptra is nearly smooth. 
E. subspathulata is undoubtedly E. rhabdocarpa, but all of the 
older capsules are badly infected by fungi and filled with hyphae.
