Nothotalisia, a new genus of Picramniaceae from tropical America

A new genus of Picramniaceae from tropical America, Nothotalisia, is described. Of the three species in the genus, N. piranii and N. cancellata, are new to science. The third, N. peruviana, was originally described as Talisia peruviana in the Sapindaceae. The genus and all three species are described, illustrated, and distinguished by means of a key.     

Fissidens viridulus Wahlenb. and F. minutulus Sull.

Abstract

A new species of Pseudocrossidium R.S.Williams, P. exiguum M.J.Cano &; J.A.Jiménez, is described from South America (Argentina, Brazil and Peru). The species is distinguished morphologically by its lingulate to oblong-ovate leaves, leaf marginal cells not or scarcely differentiated from inner, costa ending below apex or percurrent, and semicircular to elliptical in cross-section with two guide cells, scarcely differentiated perichaetial leaves and peristome of short and straight teeth. Drawings and light microscope photographs of the new species are provided. The principal distinctive characters that separate it from the nearest species of Pseudocrossidium and related genera are discussed.

On the taxonomic position of Sciaromium lacustre Herz. & Rich. in Rich.

Abstract

Sciaromium lacustre Herz. & Rich. in Rich. from Peru is misplaced in Sciaromium and a new genus, Richardsiopsis, is erected to accommodate it. Richardsiopsis is considered most closely related to Donrichardsia macroneuron (Grout) Crum & Anderson from Texas on the basis of their similar gametophyte characters including the strong costa, oblong-rhomboidal to linear-flexuose, prorate lamina cells which are partly arranged in pluristratose strands and foliose, suborbicular, broadly rounded at the apex pseudoparaphyllia.

Details of their distributions are provided, and differences between the new taxa and other species of Cololejeunea are discussed. This is also the first report of the genus Cololejeunea from St Helena.     

Ptychomitrium subcrispatum Thér. & P.de la Varde,an east southern African species excluded from the Cape Verde bryoflora

Abstract

Pictolejeunea levis, a new species of Lejeuneaceae found in N.E. Cuba, is described and illustrated. The species stands out within Pictolejeunea on account of its smooth leaf cells and the presence of ocelli on dorsal and ventral epidermal cells of the stem. Differences between this and the other four known species in the genus are discussed.     

Macromitrium maolanense Zeyou Zhang,D.D.Li,Jing Yu & S.L.Guo,a new species from China based on molecular and morphological evidence

Introduction. During a field excursion in Guizhou Province, China, we collected some interesting moss specimens with branch leaves subulate in the upper part, partially and variably bistratose laminae, and a Macromitrium-like epiphytic growth habit on tree trunks. We present morphological and phylogenetic arguments for recognising these plants as a new moss species in the genus Macromitrium Brid. (Orthotrichaceae).

Methods. We compared the morphology of the potential new species with closely related species of Macromitrium, and constructed a phylogenetic tree based on ITS2, trnL and trnG including sampling from 14 other morphologically similar species of Macromitrium.

Key results. The proposed new species belongs to the genus Macromitrium (Orthotrichaceae, Musci). It is closely related to M. gymnostomum Sull. & Lesq. in the phylogenetic tree and according to gametophytic morphological features, represents a hitherto undescribed species.

Conclusions. A new moss species, Macromitrium maolanense Zeyou Zhang, D.D.Li, Jing Yu & S.L.Guo, is described and illustrated. The new species can be distinguished from all congeners by the combination of the following features of the branch leaves: (1) oblong-lanceolate, lanceolate to linear-lanceolate, gradually narrowed to an easily broken subula; (2) rather obscure upper and medial cells, often with blackish stains among cells, densely pluripapillose; (3) variably and partially bistratose laminae in the upper 1/3 portion; (4) basal cells clear, hyaline and smooth, those near costae forming a ‘cancellina region’; and (5) with numerous brownish, clavate gemmae on upper portion. We also discuss the principal distinctive characters separating the new species from its nearest congeners.     

Bobgunnia, a new African genus of tribe Swartzieae (Fabaceae, Faboideae)

A new genus, Bobgunnia, is established in tribe Swartzieae for the African species of Swartzia. Two new combinations are made: B. fistuloides and B. madagascariensis. The new genus has seeds, unlike the remainder of tribe Swartzieae but like the other tribes of Faboideae. The systematic position of Swartzieae is reevaluated.     

A monograph of <Emphasis Type="Italic">Ascogrammitis</Emphasis>, a new genus of grammitid ferns (Polypodiaceae)

This paper describes Ascogrammitis, a new genus of grammitid ferns formerly combined under Terpsichore. Seventeen species are recognized, including five new ones: A. clavigera, A. colombiensis, A. loxensis, A. oxapampensis, and A. tungurahuae. New combinations are made for A. alan-smithii, A. anfractuosa, A. angustipes, A. athyrioides, A. clathrata, A. cuencana, A. david-smithii, A. dilatata, A. nana, A. pichinchae, A. pichinchensis, A. stuebelii, and a lectotype is chosen for Polypodium induens. A key is provided to distinguish the species, and illustrations are provided for 12 species. The genus occurs primarily in neotropical cloud forests, with the greatest diversity in the Andes. Ascogrammitis is one of two monophyletic groups of grammitid ferns that are consistently associated with Acrospermum, an epibiotic bitunicate ascomycete that produces black clavate fruiting bodies.     

Revision of the genus Adorodocia Brenske 1893 (Coleoptera: Scarabaeoidea: Rutelinae: Adoretini) endemic to Madagascar

Summary. The Adoretini of the Malagasy endemic genus Adorodocia Brenske 1893 is revised. Fourteen new species and one new subspecies are described and compared with their most closely related species: A. constricta n. sp., A. cuccodoroi n. sp., A. flava n. sp., A. liliae n. sp., A. marginata n. sp., A. peyrierasi n. sp., A. pseudoconstricta n. sp., A. pseudoflava n. sp., A. pseudostrigata n. sp., A. recta n. sp., A. robusta n. sp., A. sogai n. sp., A. vadoni n. sp., A. viettei n. sp. and A. vittaticollis flavipes n. ssp. The synonymy between Adoretus strigatus Waterhouse 1878, and Pseudadorodocia aenigma Arrow 1901, is confirmed. Thus, based on the results of this study, the genus Adorodocia includes 16 species, and one of them is represented by two subspecies. Diagnostic characters to separate the species in the genus deal mostly with the shape of parameres, color of body and legs, shape of pronotum and female eighth tergite, setation of pronotum and elytra. Key to species, diagnoses and distribution for each species are provided. Endophallus and female genitalia are illustrated for the first time for this genus.     

New species of black corals (Cnidaria: Anthozoa: Antipatharia) from the New Zealand region,part 2

ABSTRACT

One new genus and ten new species of antipatharian corals are described from the New Zealand region. Differential diagnoses are given and comparisons are made to related nominal species. Described as new is the genus Acanthosaropathes and the following species: Antipathes coronata, A. dicrocrada, A. polyhedra, Acanthosaropathes uniseriata, Phanopathes ctenocrada, Cupressopathes simplex, Stylopathes stenotes, Stauropathes stellata, Telopathes tasmaniensis, and Heteropathes intricata.

New lichenicolous, muscicolous, corticolous and lignicolous taxa of Burgoa s. l. and Marchandiomyces s. l. (anamorphic Basidiomycota), a new genus for Omphalinafoliacea, and a catalogue and a key to the non-lichenized, bulbilliferous basidiomycetes

A catalogue and a key to the non-lichenized, bulbilliferous basidiomycetes are given. The new genus Burgella is described for the lichenicolous B. flavoparmeliae, phylogenetically close to Sistotrema oblongisporum and Multiclavula. The genera Pneumatospora and Tricellulortus are placed in synonymy of Minimedusa, the new combination M. obcoronata is proposed, and the new facultative lichenicolous M. pubescens is described. The new facultative lichenicolous Burgoa angulosa is phylogenetically close to the generic type B. verzuoliana, whilst the new B. moriformis and B. splendens are provisionally included in the genus Burgoa. A Burgoa-like species in the Ceratobasidiaceae is left unnamed. Two new species of Marchandiomyces, M. buckii and M. nothofagicola, are described. As Marchandiomyces aurantiacus is phylogenetically more close to Erythricium than to Marchandiomyces, it is proposed to exclude it from that genus and to use the holomorphic generic name Marchandiobasidium for both anamorph and teleomorph of this species. The new genus Marchandiomphalina is introduced for the lichenized Omphalina foliacea, a taxon phylogenetically close to Marchandiobasidium. Taxonomic novelties Burgella Diederich & Lawrey; B. flavoparmeliae Diederich & Lawrey; Burgoa angulosa Diederich, Lawrey & Etayo; B. moriformis Diederich, Ertz & Coppins; B. splendens Diederich & Coppins; Marchandiomphalina Diederich, Lawrey & Binder; Marchandiomphalina foliacea (P. M. J?rg.) Diederich, Lawrey & Binder; Marchandiomyces buckii Diederich & Lawrey; M. nothofagicola Diederich & Lawrey; Minimedusa pubescens Diederich, Lawrey & Heylen; M. obcoronata (B.

Distichophyllum chenii B.C.Ho sp. nov. (Daltoniaceae) from Southeast China

Abstract

Despite the genus Distichophyllum having been revised recently for the Moss Flora of China, upon examination of a wide range of both Chinese and non-Chinese material a distinct new species was found among existing specimens collected from China. The new species, Distichophyllum chenii, is described based on specimens previously misidentified and reported as Distichophyllum cirratum var. cirratum. Published illustrations of D. cirratum var. cirratum based on a misidentified collection of D. collenchymatosum are highlighted to avoid further future taxonomic confusion.
