Distributional Records of Rare or Infrequently Collected Species of Mosses in Pennsylvania

Abstract

Drummondia pursellii Vitt & Crum is reported new to the state of Nuevo Le6n, Mexico. This moss was previously known only from the type locality. Vitt and Crum (1968) described Drummondia pursellii from a collection made by R. A. Pursell in Tamaulipas, Mexico. At the time of Vitt's (1972) monograph of Drummondia, this species was still known only from the original collection. During a foray to northern Mexico in January 1972, I collected D. pursellii in the state of Nuevo Le6n, near the town of Galeana in a mountainous area covered with Arbutus sp., Pinus spp., Pseudotsuga menziesii, and Quercus spp. at an elevation of 2,040 m. In contrast, the type locality was an oak covered mountain top with an elevation of 1,067 m near the city of Victoria. The new locality is about 152 km north of the type locality. It is probable that this endemic will be found elsewhere in the Sierra Madre Oriental. MEXICO. NUEVO LE6N: 43.3 km from Galeana on the road to the microwave station, W-facing ravine, on tree trunk, 2,040 m, Manuel 1289 (ALTA, PAC, HERB. MANUEL). I thank Dr. Dale H. Vitt for his identification of the specimen. Partial financial aid from the Lafayette Natural History Museum and Planetarium, Lafayette, Louisiana 70501 is acknowledged. LITERATURE CITED VITT, D.

Distributional Records of Rare or Infrequently Collected Species of Mosses in Pennsylvania Abstract. Distributional data are presented for 23 species of mosses that are either of rare or infrequent occurrence in Pennsylvania. Fissidens bushii, F. exilis, and Orthotrichum sordidum are reported for the first time from the state. Distributional data are presented for 23 species of mosses that are either of rare or infrequent occurrence in Pennsylvania. Fissidens bushii, F. exilis, and Orthotrichum sordidum are reported for the first time from the state. Taxonomic treatments of the moss flora of Pennsylvania have been published by Jennings (1951) and Moul (1952). Since then, only two additional short papers have appeared (Pursell, 1956; Ainley, 1968). The present list of species is based primarily on collections that I have made over the past few years. The majority of these collections are from the central region of the state (Cameron, Centre, Clearfield, Clinton, Huntingdon, and Mifflin counties), while a few are from the northeastern section (Luzerne and Pike counties), the southThis content downloaded from 157.55.39.104 on Sun, 19 Jun 2016 06:43:34 UTC All use subject to http://about.jstor.org/terms
