... It is possible to identify pleurocarpous mosses (mosses that create carpets) by their widespread branching and lateral sporophyte positioning (Saxena, 2004). As stated by (Ignatov et al., 1997;Ireland & Buck, 2009) this species occur on calcareous rocks and in terrestrial settings. Tropical, subtropical, and temperate regions of the planet all contain it. ...
This study was conducted to document bryophyte species in a forest patch of Pres Roxas, Cotabato, Philippines. A modified belt transect method was employed and 3 transect lines were established along the human-established trail. A total of 18 species of mosses and liverworts were identified. These species were classified under 11 families, and 14 genera. Nine (9) species of bryophytes were identified from both transect 1 and 2 while in transect 3, only 5 species thrived. Of the 18 species identified, Thiudium benguetense is found in the 3 transect lines established. Two (2) were identified endemic to the Philippines Ecthropothecium ferrugineum and Thiudium benguetense. Moreover, similarity index showed that 86% are discordant species and each transect line harbors unique species of bryophytes. It is recommended that intervention in the protection and conservation of the remaining flora community of the mountain ecosystem must be employed given that community is dependent on the water coming from it.
... Thorough review of herbarium specimens allowed us to specify and expand our knowledge on the moss diversity of the Maly Aktru glacier foreland. The check-list now includes 44 species of 28 genera and 17 families (table 1) that is 8.9% of species diversity of the moss flora of the Altai Mountains [19][20][21][22][23][24]. Acrocarpous mosses are represented by 26 species; the rest of studied mosses (18 species) are pleurocarpous. ...
Mosses are an impotent component of developing plant communities of glacier forelands of the Russian Altai Mountains. The check-list of mosses of the Maly Aktru glacier foreland includes 44 species that is 8.9% of species diversity of the moss flora of the Russian Altai Mountains. The moss species diversity of the Maly Aktru glacier foreland is significantly higher than that of other deglaciated areas of the Northern hemisphere mountain systems. Twenty-six species of the Maly Aktru glacier foreland check-list were not previously recorded on other deglaciated areas. The β-diversity values between the Maly Aktru glacier foreland and other deglaciated areas are rather high (0.123–0.276).
... However, these data refer only to features that are observable with the use of a light microscope. Only Ireland (1987Ireland ( , 2001 and Ignatov et al. (1996) have described the species of this genus using a Scanning Electron Microscope (SEM). Even so, their studies are fragmentary, referring only to a few selected species and sporophytic structures of these taxa. ...
... Many species of Plagiothecium have never been the object of SEM research. Although three studies have examined the micromorphology of species of Plagiothecium (Ireland, 1987;Ignatov et al., 1996;Ireland, 2001), the cited articles did not address the sporophytes of P. nemorale. ...
Plagiothecium nemorale sensu lato is described as a variable Eurasian taxon. Recent studies indicate that this variability is reflected in both qualitative and quantitative features of its gametophyte and its genetic variation. This taxon comprises at least two separate species: P. nemorale (Mitt.) A. Jaeger and P. longisetum Lindb. The present paper examines whether the gametophyte variability of these species is reflected in the micromorphological variation of the sporophyte. The analysis revealed that the seta of P. nemorale is shorter than that of P. longisetum. In addition, regarding the exostome teeth, the lower portion of the outer surface is characterised by loosely-arranged, moniliform cristae in P. nemorale, with conical papillae on the upper side; however, in P. longisetum it possesses tightly arranged, epapillose cristae, with clearly flattened papillae on the upper side. In addition, the inner surface is more gently papillose in P. nemorale than in the latter. These findings not only describe hitherto unknown features of the sporophyte of these species, but also justify the resurrection of P. longisetus as separate from P. nemorale.
... It is closely related to Hypnum and it usually grows in coniferous and deciduous forests. The total number of species occurring worldwide are still unclear but according to the available literature, the number ranges from 32 to 37 species (Ando, Persson, & Sherrard, 1957;Brotherus, 1922;Higuchi, 1985;Ignatov, Ando, & Ignatova, 1997;Nishimura, 1984 (Ignatov et al., 1997;Schlesak et al., 2018 have been reported from Asia. So it is obvious that the genus is geographically oriented in Asia specifically in Eastern Asia (Ando, 1965;Higuchi, Nishimura, & Inoue, 1994;Loeske, 1907;Schimper, 1860). ...

The Hypnaceae is one of the largest and diversified family among the pleurocarpous mosses which consists of nearly 60 genera and 1,000 species around the world. In Pakistan, it is represented by 15 species and 8 genera. The current research article provides the detail morphological investigation of four different species (genera) of the family Hypnaceae that is, Gollania clarescens, Hypnum revolutum, Homomallium andoi, and Taxiphyllum taxirameum in the Western Himalayas, Pakistan. The research article reports the first SEM study of the leaf surfaces of the studied taxa, along with comprehensive morphological characters of the four species. The main objective of the research project is to present the comparative light and scanning electron microscopic study to discuss the morphology in detail because previously the family is just reported in different bryophyte checklists of the Western Himalayas. Based on results, morphological characters, micromorphological observations, qualitative and quantitative attributes, taxonomic keys for the studied taxa, distribution, and habitat are described. Stereoscope was used to analyze different qualitative characters, and light microscope was used to observe and measure the laminal and alar cells of the leaf. The SEM study reveals many important surface features like cell shape and cell wall. The laminal cells were mostly linear and elongated with thin cell walls. The specimens used for the SEM were air dried, so the laminal cells were somewhat constricted and concaved. The current study project will help to make the contribution in the taxonomy and morphology of this family.

... (Nyholm, 1965;Corley et al., 1981;Ignatov & Afonina, 1992;Lüth, 2010) but based on the smooth laminal cells and lack of differentiation in stem and branch leaves most authors have placed this taxon in Hypnum. However, its segregation was stated by Ignatov et al. (1997) to justify further splitting of Hypnum. Hypnum procerrimum was described by Molendo (1866) on the basis of material collected in the Austrian Alps. ...
Molecular phylogenetic reconstructions support the monophyly of Pylaisiaceae. The family includes Calliergonella Loeske, Homomallium (Schimp.) Loeske, Pseudohygrohypnum Kanda, Pylaisia Schimp., 2 further genera formerly placed in Hypnaceae, Ectropothecium Mitt. and Vesicularia (Müll.Hal.) Müll.Hal., as well as several species of Hypnum Hedw. recently considered to belong to Stereodon (Brid.) Rchb. Calliergonella, Ectropothecium, Pylaisia, Pseudohygrohypnum and Vesicularia, are monophyletic based on the present data, whereas Homomallium is resolved as a paraphyletic sister group to Pylaisia. Stereodon is excluded from Pylaisiaceae since its type species, S. callichrous (Brid.) Lindb., is resolved outside the Pylaisiaceae clade. Based on morphological and molecular evidence 2 new genera, Roaldia and Buckia, are described to accommodate the former Hypnum (Stereodon) species H. revolutum (Mitt.) Lindb. and H. vaucheri Lesq. respectively. The genus Pseudostereodon (Broth.) M.Fleisch. is re-established to accommodate Hypnum procerrimum Molendo. Morphological descriptions and illustrations of distinctive characters in these 3 taxa are provided and lectotypes for 2 names are designated. New distributional data is also provided for Roaldia new to Guatemala. A key to the genera of Pylaisiaceae is presented.
