Notes on Fissidens VII–IX

Abstract

Note VII: Fissidens ah-pengae and F. aristifer spp. nov. are described and figured. The first is known from La Réunion, the second from Madagascar and La Réunion. Both belong to subgenus Aloma.

Note VIII: Fifteen new synonyms are proposed: Fissidens bryoides Hedw. var. glaucus Brid. is subsumed under F. crassipes Wilson ex Bruch & Schimp., F. comorensis Müll.Hal. under F. crispulus Brid., F. sigmocarpoides P.de la Varde under Fissidens erosulus (Müll.Hal.) Paris, F. atroviridis Besch., and F. luridus Renauld & Cardot under F. flaccidus Mitt., Moenkemeyera rarotongae Dixon and Fissidens jonesii Bizot ex Pócs under F. lagenarius Mitt. var. lagenarius, F. onraedtii Bizot nom. nud. under F. madecassus Schimp. ex Müll.Hal., F. bryum var. terrestris P.de la Varde under F. metzgeria (Müll.Hal.) Broth., F. edamensis M. Fleisch. under F. pallidinervis Mitt., F. brunnthaleri var. filipes Dixon & P.de la Varde under F. ramulosus Mitt., F. desertorum (Müll.Hal.) Paris and F. bambariensis Broth. & P.de la Varde under F. reflexus Hampe, F. usambaricus var. acutifolius P.de la Varde under F. usambaricus Broth. and F. glauculus var. circinicaulis (Cardot) P.de la Varde under F. weirii Mitt. Fissidens gedehensis M. Fleisch. is re-instated as a good species.

Note IX: Fifty-five new country and state records including F. anguste-limbatus Mitt. new to Africa. Fissidens pocsii Bizot & Dury ex Pócs is the first record of an epiphyllous species of this genus. The African distributions of F. flaccidus and F. pallidinervis are amended.     

On the identities of some neglected species of Grimmiaceae from Îles Kerguelen

Taxonomic status of five species of Grimmia Hedw. (G. minuta Müll.Hal., G. suborthotrichacea Müll.Hal., G. defoliata Müll.Hal., G. genuflexa Müll.Hal., and G. orthotrichacea Müll.Hal.) is appraised. All these species correctly belong within the genus Bucklandiella Roiv. They are actually inseparable from one another and represent a single species for which B. orthotrichacea (Müll.Hal.) Bednarek-Ochyra & Ochyra is chosen as the final name. The remaining four names are considered its synonyms, all but G. genuflexa being new. All the names are lectotypified and some details of the leaves of G. minuta and G. defoliata are illustrated.     

Vittia salina L.Hedenäs & J.Muñoz,sp. nov., a new moss from Argentina

Abstract

A survey of the species of Campylopus Brid. reported from Sri Lanka (Ceylon) is presented. Of the 34 species that have been reported from this Island 16 are accepted at present. Campylopus nilghiriensis (Mitt.) Jaeg. is identical partly with C. goughii (Mitt.) Jaeg., partly with C. zollingerianus (C. Müll.) Bosch &; Lac., C. pseudogracilis Card. &; Dix. with C. goughii (Mitt.) Jaeg., C. caudatus (C. Müll.) Mont., C. reduncus (Reinw. &; Hornsch.) Bosch &; Lac. and C. trachythecius (C. Müll.) Jaeg. with C. comosus (Reinw. &; Hornsch.) Bosch &; Lac., C. herzogii Broth., C. subtricolor Lor. and probably also C. nodijlorus (C. Müll.) Jaeg. with C. aureus Bosch &; Lac., C nietneri (C. Müll.) Jaeg. with C. involutusz (C. Müll.) Jaeg., C. subgracilis Ren. &; Card. ex Gangulee and C. latinervis (Mitt.) Jaeg. with C. gracilis (Mitt.) Jaeg., and C. laetus (Mitt.) Jaeg. with C. savannarum (C. Müll.) Mitt. C. pterotoneuron (C. Müll.) Jaeg. is reduced to a variety of C. umbellatus (Arn.) Par. The occurrence of C. exasperatus Brid. on Sri Lanka could not be confirmed. Campylopus flagelliferus (C. Müll.) Jaeg. is reported as new to Sri Lanka.     

Notes on the little known moss Fissidens firmus Mitt. (Fissidentaceae)

Abstract

Fissidens firmus is revised, described, illustrated and a distribution is provided. It is compared to Fissidens hollianus, Fissidens pseudofirmus, Fissidens sedgwickii and Fissidens touwii. It is provisionally distinguished from F. firmus sensu auct. Fissidens multiflorus is reduced to F. hollianus. Lectotypes are designated for Fissidens multiflorus and Fissidens giesenhagenii. The collection that was reported from India as F. firmus appears to be F. hollianus. Thus, the present Western Ghats collection is effectively the first Indian record of F. firmus.     

A contribution to the knowledge of epiphyllous bryophytes of Bioko Island (Equatorial Guinea), including additional remarks on non-epiphyllous species

Abstract

A collection of epiphyllous bryophytes from Bioko Island was investigated. It contained 57 epiphyllous bryophytes, comprising 55 hepatics and two mosses. Three taxa, Cololejeunea eustacei Pócs, Colura calderae Pócs and Lejeunea halei Robinson subsp. africana Pócs, are new to science. Cololejeunea papilliloba Steph. is new to Africa, five species of hepatics are new to West Africa, and an additional 31 species of hepatics are newly reported from Bioko Island. The second part of the paper deals with records of non-epiphyllous collections. Fourteen species are reported for the first time for Bioko Island. Actinodontium dusenii Broth. is made a synonym of Actinodontium streptopogoneum Broth. The following new combination is proposed: Wijkia rigidicaule (Müll.Hal. ex Broth.) Frank Müll., comb. nov. (Basionym: Acanthocladium rigidicaule Müll.Hal. ex Broth.).     

Tetraphis browniana var. repanda (Funck) Hampe—New to the British Isles

Abstract

Syrrhopodon spiculosus Hook. &; Grev. and some associated taxa are revised. Syrrhopodon elimbatus Dixon and Syrrhopodon patens Dixon are confirmed as synonymous with S. spiculosus; Syrrhopodon hispidissimus Dixon and Syrrhopodon scalariformis Dixon are recognized as distinct species; S. spiculosus ssp. bokorenis Tixier is recognized as a synonym of S. mammillosus Müll.Hal. and Syrrhopodon perarmatus Broth. in Broth &; Watts is placed in synonymy with Syrrhopodon subciliatus Müll. Hal. Two new species are described from Borneo: Syrrhopodon teniolatus L.T.Ellis, sp. nov., which resembles S. hispidissimus but has a differentiated rib (teniola) within the margin of the distal hyaline leaf base, and Syrrhopodon multipapillosus L.T.Ellis, sp. nov. This resembles a miniature version of Syrrhopodon kilauae Müll.Hal. but has cells in the chlorophyllose lamina exserted dorsally and/or ventrally as tall, papillose projections.     

Typification,taxonomy, and worldwide distribution of Braunia secunda (Hook.) Bruch & Schimp. (Hedwigiaceae)

Diagnosis and illustrations are given for Braunia secunda (Hook.) Bruch & Schimp., and a Humboldt and Bonpland specimen (BM) is selected as the lectotype. Also a collection by Arséne (BM) is designated as the lectotype for B. secunda var. crassiretis Thér. This variety is retained as synonym of B. secunda. The species concept of B. secunda is revised and a provisional key is provided to help in the identification of 23 species of Braunia, based on examination of herbarium specimens worldwide. About half of specimens from Mexico actually represent another species, B. andrieuxii Lorentz. All material examined from India, previously identified as B. secunda belongs to B. macropelma (Müll.Hal.) A.Jaeger, whereas collections from Africa are actually B. rupestris (Mitt.) A.Jaeger, B. entodonticarpa Müll.Hal., or B. diaphana (Müll.Hal.) A.Jaeger. These and other species should no longer be considered synonyms of B. secunda. The worldwide distribution of the species is documented for the United States, Mexico, Guatemala, Dominican Republic, Haiti, Venezuela, and Bolivia.     

Taxonomic notes on Calymperes erosum Müll.Hal. (Calymperaceae), C. palisotii Schwägr. and related West African taxa

The lectotype for Calymperes erosum Müll.Hal. is re-established, and lectotypes are designated for three West African taxa: Calymperes asterigerum Müll.Hal. ex Besch., C. leucomitrium Müll.Hal. and C. proligerum Dusén. Calymperes asterigerum and C. leucomitrium are placed in synonymy with C. erosum, and C. proligerum with C. palisotii Schwägr. A revised key to the seven species of Calymperes occurring in West Africa is provided.     

A new combination in Pseudosymblepharis (Pottiaceae) from South and Central America

Abstract

Trichostomum schlimii Müll.Hal., a neglected Colombian taxon, is transferred to the genus Pseudosymblepharis Broth. as Pseudosymblepharis schlimii (Müll.Hal.) comb. nov. The species, known only from the type locality in Santa Marta, Colombia, is newly reported for the moss floras of Bolivia, Brazil, Dominican Republic, Ecuador, Guiana, Peru, and Venezuela. It is described, lectotypified, illustrated, and mapped. Diagnostic characters, and distinction from one closely related American species within the genus are discussed. Trichostomum mollissimum (Broth. ex E.B.Bartram) H.A.Crum and Pseudosymblepharis guatemalensis (E.B.Bartram) B.H.Allen are reduced to the synonymy of Pseudosymblepharis schlimii.     

Additions to the bryoflora of Réunion Island 3: new and interesting records from the Tropical Bryology Group (British Bryological Society)

Abstract

This contribution is a result of collaborative work based on the fieldwork organized during a workshop of the Tropical Bryology Group on Mascarene bryophytes in September 2008, and also from previous unpublished records of the authors. We add 35 new taxon records (17 mosses and 18 liverworts) as well as five other interesting records for Réunion Island (Mascarene Archipelago). Grimmia austrofunalis Müll. Hal., Sphagnum magellanicum Brid. subsp. magellanicum, Didymodon tectorum (Müll. Hal.) K. Saito, Anastrophyllum revolutum Steph. and Lejeunea exilis (Reinw. et al.) Grolle are reported for the first time for Africa. Syrrhopodon vardei L. T. Ellis, Ceratolejeunea papuliflora Steph. and Xylolejeunea grolleana (Pócs) X.-L. He & Grolle, previously known as endemic from Madagascar, are here recorded for Réunion. The latter species is also illustrated with SEM pictures.     

New and noteworthy records of mosses from Italian national and regional Parks

Some remarkable mosses, as a result of the study of both recent collections and a review of herbarium specimens, are reported in this paper. They are: Anomodon rugelii (Müll.Hal.) Keissl., new record from southern Italy, a moss very rare in the Mediterranean region and considered threatened in many European countries; Blindia acuta (Hedw.) Bruch & Schimp. and Dichodontium palustre (Dicks.) M. Stech, both new records from Sicily, are very rare mosses in Italy. Moreover, a new locality in Sicily for the little-known species Tortula bolanderi (Lesq. & James) M. Howe is reported.     

On Barbula munyensis R.S.Williams (Pottiaceae), an overlooked species from the tropical montane forest of South America

Abstract

Barbula munyensis R.S.Williams, a neglected moss species known only from the type material collected in central Peru in 1923, is newly reported for the moss floras of Argentina and Bolivia. The species is described, illustrated, mapped, and its habitat preferences are provided. Diagnostic characters and differentiation from some closely related South American taxa, with which it may be confused, are discussed. Barbula orizabensis Müll.Hal., a similar taxon, is excluded from the South American moss flora.     

Mosses of southwest Ethiopian montane forests – notes on their occurrence pattern and many new country records

One hundred and thirty-nine taxa of mosses are reported from the montane forest zone of southwest Ethiopia. Of these, 53 taxa are new country records and Meteoriopsis reclinata (Müll.Hal.) M.Fleisch. ex Broth. is, in addition, new to Africa. Most of the new records are of species also found in Uganda, Kenya or Tanzania, but there are some surprises, such as Fabronia perciliata Müll.Hal. with the closest location in South Africa and Namibia, Entodontella cameruniae Broth. previously known only from West Africa and Bryomaltaea obtusifolia (Hook.) Goffinet, otherwise reported only from the Democratic Republic of the Congo. We list all taxa and give a short account of their frequency and in which habitat and on which substrate they grow. That such a large proportion of the species are new to the country suggests that Ethiopia is bryologically very under-explored, and that further exploration will reveal many additional species. In particular, the remnant forests of southwest Ethiopia are likely to be of great importance as bryophyte hotspots.     

Three new synonyms of Macromitrium microstomum (Hook. & Grev.) Schwägr. (Bryophyta,Orthotrichaceae), with comments on its morphological variations

Macromitrium filicaule Müll.Hal., M. pacificum var. brevisetum Thér. and M. subnitidum Müll.Hal are placed in synonymy with Macromitrium microstomum (Hook. & Grev.) Schwägr. The morphological variations of M. microstomum branch leaves, perichaetial leaves and capsules are illustrated by digital images.     

Four new hepatics from Australia

Abstract

A new species, Racomitrium patagonicum Bednarek-Ochyra &; Ochyra, is described from southern South America. A herbarium name, R. senile Schimp. in A. Jaeger, is considered synonymous with R. patagonicum and confusion associated with its interpretation is explained. The new species belongs to the type subgenus of Racomitrium and is closely alied to R. lanuginosum (Hedw.) Brid. from which it differs by the very long and broadly decurrent, ruffled or wavy margins of the hyaline hair-point, broadly canaliculate leaves and dull green, strongly papillose laminal cells. Grimmia glacialis Müll. Hal., hom. illeg. (=Racomitrium glaciale Kindb.) from South Georgia is typified and this name is considered synonymous with Racomitrium lanuginosum subsp. lanuginosum. Distribution of the new species is mapped. A key to species of Racomitrium subg. Racomitrium is provided.
