Abstract: Allen C. Risk'Collecting efforts in Kentucky, mainly the eastern part of the state, over the past several years have resulted in twenty-one new mosses for the state and the discovery of additional localities for many taxa uncommon in the region.All collections listed below are those of the author, unless otherwise indicated, and are housed in MDKY (Herbarium of Morehead State University).Species marked with an asterisk are new reports for Kentucky.Abietinella abietina (Hedw.)Fleisch.Estill Co.: knob 0.5 mile north of Ravenna, very narrow ridge with little tree cover, on limestone, 4704; Preacher Estes Mt. narrow north-facing limestone point, on small ledges, 6077.Rowan Co.: Cave Run Lake area, between Long Br. and Ham Br., on limestone in semi-open forest, 55/6.The three new localities are xeric and calcareous, which accords well with the habitat assessment provided for A. abietina by Crum and Anderson (1981).Smith (1927) provided the first report of this species from Kentucky.Catling et al. (1993), in a description of a new sedge species, Carex juniperorum, also indicated A. abietina was present at the sites in Kentucky and Ohio with the sedge, but did not provide specific locality data for the moss.Amphidium mougeotii (Bruch & Schimp. in B.S.G.)
