Prominent among the names of the many bryologists who have collected in Colorado are those of Leo Lesquereux, T. S. Brandegee, T. C. Porter, and A. J. Grout. Their findings are discussed by Dr. Geneva Sayre in an unpublished dissertation on the mosses of Colorado, a work completed in 1938 (2). She points out that, with the exception of Brandegee\u27s collections in southwest Colorado, collections of southern Colorado mosses are either meagre or lacking. The largest reported collection of recent date from southern Colorado is that of Dr. Belle K. Stewart who collected fourteen species in the Creede Valley incident to an ecological study of its vascular flora. It is known that H. S. Conard, Frederick McAllister and others have collected specimens in southern Colorado but the present writers have been unable so far to find published reports of their findings
