Leucoloma serrulatum, Brachymenium systylium, Macromitrium cirrosum, M. fragilicuspis, Schlotheimia rugifolia and Zelometeorium allionii are reported new to Nicaragua along with twelve additional Departmental records. In a preliminary survey of the Nicaraguan moss flora, Crum (1952) considered Nicaragua to be bryologically the least known of all Central American countries. Since that time only a single paper (Crosby & Crum 1967) has been published on the mosses of Nicaragua. The mosses reported below were collected by Frank Almeda in May 1972. Included in this list are six species new to Nicaragua and eighteen Department records. These species, however, for the most part represent taxa that are commonly found from Mexico and the West Indies to northern South In the following list, taxa new to Nicaragua are marked by an asterisk, all others are Department records. Voucher specimens are deposited in the herbarium of the University of Cincinnati (cINc). All collections were made in two localities on three days. To simplify the citing of the collections the following abbreviations are used: MATAGALPA: Department of Matagalpa, wooded slopes of cloud forest, partially disturbed and in coffee plantations at the Hacienda Santa Maria de Ostuma, elev. ca. 1200 m, 15 May 1972. This station is, as far as mosses are concerned, one of the most commonly collected in Nicaragua. GRANADA: Department of Granada, road to Hacienda Santa Teresa and Hacienda La Trinidad, cloud forest along ascent to the crater of Volcan Mombacho, elev. ca. 960 m, 16 & 17 May 1972. Campylopus tallulensis Sull. & Lesq. ex Sull. MATAGALPA: Decaying logs, Almeda 1453d. According to Frahm (pers. comm.) this species is relatively common in Mexico but has not been reported very often from countries to the south. *Leucoloma serrulatum Brid. GRANADA: Upper trunks of hardwoods, Almeda 1460c. Trichostomum tenuirostre (Hook. & Tayl.) Lindb. MATAGALPA: Decaying logs, Almeda 1453b. Bryum billardieri Schwaegr. MATAGALPA: Decaying logs, Almeda 1453c. A moss of pan-tropical distribution (Ochi 1980). This species has been reported from Nicaragua as B. truncorum (Crosby & Crum 1967), a moss now considered restricted to Madagascar and Reunion Island (Ochi 197 1). *Brachymenium systylium (C. Miill.) Jaeg. MATAGALPA: Upper trunks of hardwoods, Almeda 1452c. Rhizogonium spiniforme (Hedw.) Bruch. GRANADA: Upper trunks of hardwoods, Almeda 1460a. Cosmopolitan in tropical and subtropical regions. Groutiella apiculata (Hook.) Crum & Steere. MATAGALPA: Upper trunks of hardwoods, Almeda 1452b. *Macromitrium cirrosum (Hedw.) Brid. GRANADA: Twigs of shrubs, grassy windswept meadows at summit of Volcin Mombacho, Almeda 1458. *Macromitriumfragilicuspis Card. MATAGALPA: Decaying logs, Almeda 1453f Previously known only from Mexico and Guatemala (Bartram 1949). *Schlotheimia rugifolia (Hook.) Schwaegr. MATAGALPA: Upper trunk of hardwoods, Almeda 1452a. Distributed from southern United States to northern South America, Bartram (1949) considered this moss to be ... the commonest species in tropical America. Racopilum tomentosum (Hedw.) Brid. MATAGALPA: On exposed roots of hardwood, Almeda 1454a. Orthostichidium pentagonum (Hampe & Lor.) C. Miill.

Fleisch. MATAGALPA: Upper trunk of hardwoods, Almeda 1450a. Found in tropical America from Mexico to Panama. Meteoridium remotifolium (C. Miill) Manuel. GRANADA: Upper branches of hardwoods, Almeda 1459c. According to Manuel (1977a) this species is found from Mexico to South America where it occurs as far south as central Chile. Papillaria nigrescens (Hook.) Broth. MATAGALPA: Decaying logs, Almeda 1453a. Widespread from Louisiana and Florida to Ecuador, Bolivia and Brazil. Pilotrichella rigida (C. Miill.) Besch. GRANADA: Upper branches of hardwoods, Almeda 1459b. Widespread from Mexico to northern South America; Robinson (1967) considered this taxon to be part of a complex centered nomenclaturally on Pilotrichella pentasticha. Squamidium nigrescens (Hook.) Broth. MATAGALPA: Upper trunks of hardwoods, Almeda 1451b; decaying logs, Almeda 1453e. *Zelometeorium allionii Manuel. GRANADA: Upper trunks of hardwoods, Almeda 1460b. Known previously only from Costa Rica and Ecuador (Manuel 1977b), this Nicaraguan station represents a northern range extension for this species.
