Breutelia

Abstract: Parsimony analyses of 21 to 29 representatives of the family Bartramiaceae and of six outgroup taxa of Aulacomniaceae, Bryaceae, Plagiomniaceae, Meesiaceae, Rhizogoniaceae, and Timmiaceae were performed. Combined and separate analyses based on morphological data and three chloroplast loci (the genes rbcL and the rps4, and the trnL-trnF gene region) were carried out. Based on the combined analysis, the Bartramiaceae appear to be a monophyletic group including Anacolia, Bartramia, Breutelia, Conostomum, Fleischerobryum, Flowersia, Leiomela, Neosharpiella, Philonotis, and Plagiopus. The same result was also obtained from the analyses of rbcL and morphological data. Catoscopium is excluded from the family.

Abstract: A checklist is given of the mosses of Bhutan based on published reports. Totals of 156 genera and 282 species are recorded. The main past collectors of mosses in Bhutan are listed, together with sources of erroneous reports; 44 erroneous and doubtful taxa are excluded. The name Breutelia setschwanica is applied to the only Himalayan member of the genus. The name Barbula flavicans is proposed as an avowed substitute for the illegitimate Tortula flavescens Hook. & Grev. (Barbula fuscescens C. Mull. nom. inval.)

Abstract: The mosses (Bryophyta) of Polylepis sericea (Rosaceae) forests from Merida state (Venezuela). Herein, we publish a list of 90 species of mosses associated with Polylepis sericea forests in Merida, Venezuela. The Leucobryaceae family is the most diverse with 14 species followed by Bryaceae, Bartramiaceae and Pottiaceae. The most diverse genera are Campylopus (14 species), Leptodontium (5), Breutelia (4), Bryum (4), Zygodon (4) and Racomitrium (3). In these forests the acrocarpic mosses are dominant: represented by 68 species, of which tall turfs are the most frequent (41.11%), followed by short turfs (24.44%) and extensive mats (8.89%). The phytogeographic analysis shows a predominance of neotropical elements (36%), over worldwide distributed elements (27%). Thirty-nine species are exclusive to Sierra Nevada of Merida and 34 to Sierra de la Culata. Only 19% of the species is shared by both Sierras, indicating that there is high beta diversity in the studied forests. In Venezuela the bryoflora of Polylepis forests is more similar to the Bolivian forests. The species Drepanocladus sordidus (Amblystegiaceae), Myurella sibirica (Plagiotheciaceae) and Pleurochaete luteola (Pottiaceae) are added to Venezuelan moss flora, as well as nine new records for the bryoflora of the Merida state.
