Nineteen county records are reported from collections made in Waubonsie State Park, Fremont County, Iowa, including two species new to the state, Fissidens osmundoides Hedw. and Frullania brittoniae Evans. A series of collections from Waubonsie State Park (Washington twp., T67N,R42W) were made by the junior author in June of 1976 as part of a Fremont County foray cosponsored by the Iowa Ornithological Union and The Iowa State Preserves Board. The park features xeric, loess bluffs with sheltered ravines supporting oak-hickory forest. Identifications of these collections were made by the senior author, and the results were compared with the county flora reported by Conard (1956). The 35 species collected in the park included 19 species not previously reported from the county, of which two species are new to Iowa, as well as the second report of Tortella tortuosa and the third report of Leskeella nervosa in Iowa. Eight records reflect a significant westward extension of the Iowa distribution of that species. In the county records listed below significant extensions are noted with an asterisk (*) and state records with a dagger (t). Specimens are deposited at Conard Bryophyte Herbarium, University of Iowa, Iowa City (IA). The records are as follows: Atrichum angustatum (Brid.) B.S.G., *Barbula fallax Hedw., Bryum lisae DeNot var. cuspidatum (B.S.G.) Marg., *Bryum pseudotriquetrum (Hedw.) Gaertn., Meyer & Scherb., *Callicladium haldanianum (Grev.) Crum, *Desmatodon obtusifolius (Schwaegr.) Schimp., Dicranella varia (Hedw.) Schimp., Entodon cladorrhizans (Hedw.) C.Muell., Entodon seductrix (Hedw.) C.Muell., tFissidens osmundoides Hedw., tFrullania brittoniae Evans, Frullania eboracensis Gott., Leskea obscura Hedw., *Leskeella nervosa (Brid.) Loeske, Phaeoceros laevis (L.) Prosk., *Pohlia nutans (Hedw.) Lindb., Pylaisiella selwynii (Kindb.) Crum, Steere & Anderson, *Rhynchostegiella compacta (C.Muell.) Loeske and *Tortella tortuosa (Hedw.) Limpr.
