A New Species

A new species, Chaetopsina aquatica, collected from the River Nile, Sohag, Egypt, is described and illustrated. Phylogenetic analyses of the combined ITS and LSU rDNA placed the new species within Chaetopsina as a phylogenetically distinct species. Chaetopsina aquatica formed a basal clade to a node containing C. aurantisalinicola and C. penicillata. The new species is characterized by its longer conidia (20–35.2 × 5–8.5 μm on natural substrate, 27.5–41.5 × 5–7 μm in culture) than those reported in Chaetopsina species.

A new species, Pleurotheciella nilotica is described and illustrated from the River Nile, Sohag, Egypt. Molecular phylogenetic analyses of the combined SSU and LSU rDNA placed the new species within Pleurotheciella as a phylogenetically distinct species. P. nilotica formed a basal clade to a node containing P. krabiensis and P.tropica. The new species is characterized by its conidial dimensions being smaller than those recorded in the eleven described species of Pleurotheciella.

A New Species

During a soil survey for Mucorales in a semiarid region of the state of Pernambuco, Brazil, a specimen of Absidia (URM 8213) was isolated. Both morphological and phylogenetic analyses (ITS and LSU rDNA regions) of this specimen showed that it is a new species. The new species differs from other species in the genus in its ability to concomitantly produce isolated or whorled sporangiophores of up to 8 with fig-shaped and hemispherical columellae, as well as globose, subglobose, and cylindrical sporangiospores. Thus, in this study, we propose a new species of Absidia.

Gloiosaccion Harvey, with type G. brownii (Rhodymeniaceae, Rhodymeniales), is a red algal genus characterized by the presence of large, hollow and saccate vesicle-shaped thalli arising from small solid axes. Whereas Gloiosaccion has traditionally been viewed as being closely related to Botryocladia (Agardh) Kylin, a multi-marker phylogenetic analysis based on chloroplast-encoded rbcL and UPA and nuclear LSU rDNA sequences instead places Gloiosaccion brownii and G. pumila in the Chrysymenia clade that includes the generitype C. ventricosa (Lamouroux) J. Agardh. Gloiosaccion is reduced to synonymy with Chrysymenia J. Agardh, a taxonomic move first advocated by De Toni in 1900. In addition to C. brownii (Harvey) De Toni, “Gloiosaccion” brownii var. firmum Harvey and “G.” pumilum J. Agardh are recognized as the distinct species Chrysymenia coriacea comb. et stat. nov. and C. pumila (J. Agardh) Weber-van Bosse, respectively. A new species, C. pseudoventricosa sp. nov. is proposed to accommodate specimens going under the name C. ventricosa (J.V. Lamouroux) J. Agardh from the Gulf of Mexico and Caribbean Sea.

AbstractFossil catostomids were very rare prior to the Eocene. After the Eocene, they suddenly decreased in diversity in Asia while becoming common fishes in the North American fauna. Knowledge of the taxonomy, diversity, and distribution of Eocene catostomids is critical to understanding the evolution of this fish group. We herein describe a new catostomid species of the genus †AmyzonCope, 1872 from the Eocene Kishenehn Formation in Montana, USA. The new species, †Amyzon kishenehnicum, differs from known species of †Amyzonin having hypurals 2 and 3 consistently fused to the compound centrum proximally, and differs from other Eocene catostomids in that the pelvic bone is intermediately forked. All our phylogenetic analyses suggest that the new species is the sister group of †A.aggregatumWilson, 1977 and that †Amyzonis the most basal clade of the Catostomidae. We reassessed the osteological characters of the North American species of †Amyzonfrom a large number of well-preserved specimens of the new species, as well as †A.gosiutenseGrande et al., 1982 and †A.aggregatum. Osteological characters newly discovered indicate that †A.gosiutenseis not a junior synonym of †A.aggregatum, but should be retained as a distinct species.

The genus Caliciopsis (Eurotiomycetes, Coryneliales) includes saprobic and plant pathogenic species. Caliciopsis canker is caused by Caliciopsis pinea Peck, a species first reported in the 19th century in North America. In recent years, increasing numbers of outbreaks of Caliciopsis canker have been reported on different Pinus spp. in the eastern USA. In Europe, the disease has only occasionally been reported causing cankers, mostly on Pinus radiata in stressed plantations. The aim of this study was to clarify the taxonomy of Caliciopsis specimens collected from infected Pinus spp. in Europe and North America using an integrative approach, combining morphology and phylogenetic analyses of three loci. The pathogenicity of the fungus was also considered. Two distinct groups were evident, based on morphology and multilocus phylogenetic analyses. These represent the known pathogen Caliciopsis pinea that occurs in North America and a morphologically similar, but phylogenetically distinct, species described here as Caliciopsis moriondisp. nov., found in Europe and at least one location in eastern North America. Caliciopsis moriondi differs from C. pinea in various morphological features including the length of the ascomata, as well as their distribution on the stromata.

Initially described in 1882, Chromis enchrysurus, the Yellowtail Reeffish, was redescribed in 1982 to account for an observed color morph that possesses a white tail instead of a yellow one, but morphological and geographic boundaries between the two color morphs were not well understood. Taking advantage of newly collected material from submersible studies of deep reefs and photographs from rebreather dives, this study sought to determine whether the white-tailed Chromis is actually a color morph of Chromis enchrysurus or a distinct species. Phylogenetic analyses of mitochondrial genes cytochrome b and cytochrome c oxidase subunit I separated Chromis enchrysurus and the white-tailed Chromis into two reciprocally monophyletic clades. A principal component analysis based on 27 morphological characters separated the two groups into clusters that correspond with caudal-fin coloration, which was either known or presumed based on the specimen’s collection site according to biogeographic data on species boundaries in the Greater Caribbean. Genetic, morphological, and biogeographic data all indicate that the white-tailed Chromis is a distinct species, herein described as Chromis vanbebberaesp. nov. The discovery of a new species within a conspicuous group such as damselfishes in a well-studied region of the world highlights the importance of deep-reef exploration in documenting undiscovered biodiversity.

Amanita rufobrunnescens is described as a new species in the subgenus Lepidella section Amidella from Guangdong Province, China. It is characterized by whitish basidiomes that bruise reddish brown, brownish sub-membranous to fibrillose volval remnants on the pileus, a striate pileus margin, white lamellae with truncate lamellulae, grayish orange to light brown volva, amyloid basidiospores that are ellipsoid to elongate (9.5–)10–12(–13) × (5–)5.5–6.5(–7) µm, and 5–10 μm wide pileipellis hyphae with yellowish vacuolar pigments. There are no clamp connections. Molecular phylogenetic analyses based on the nuclear ribosomal large subunit of nuclear ribosomal DNA (LSU) and internal transcribed spacer (ITS) sequences reveal that A. rufobrunnescens is a distinct species.

Based on molecular evidence and morphological analyses, a new species in the genus Trametopsis is revealed. Trametopsis aborigena sp. nov. is proposed and described from South America. Molecular phylogenetic analyses of ITS and LSU rDNA sequences suggest that Trametopsis cervina seems to encompass more than one species and confirm previous results showing that Antrodiella brasiliensis groups with Trametopsis. The morphological analyses of type specimens of A. brasiliensis and A. luteocontexta revealed a shared morphological pattern with Trametopsis and their combinations in Trametopsis are proposed. The circumscription of Trametopsis is discussed since all the studied specimens revealed a previously overlooked arrangement of characters, i.e., cylindrical and slightly curved to allantoid basidiospores and a metachromatic hyphal system monomitic in the context and dimitic in the tubes.

Abstract Based on molecular phylogenetic analyses of a multigene matrix of partial nuSSU-ITS-LSU rDNA, RPB1, RPB2 and TEF1 sequences and by morphological evidence, the genus Mycosphaerangium is shown to be the closest relative of Neomelanconium, and confirmed to be a member of the Cenangiaceae (Leotiomycetes). While Mycosphaerangium and Neomelanconium share many traits like similar conidia, conidiogenesis, asci and ascospores, their apothecia differ particularly in excipular features and are therefore recognized as distinct genera. Mycosphaerangium tiliae, described from North America, is excluded from the genus but shown to represent the sexual morph of the European Neomelanconium gelatosporum, and it is therefore synonymized with the latter. Based on morphology, Neomelanconium deightonii is assumed to be congeneric with Neomelanconium gelatosporum, and it is lectotypified. Dermatea tetraspora and Phaeangium magnisporum, the basionyms of Mycosphaerangium tetrasporum and M. magnisporum, respectively, are lectotypified as well, and for M. tetrasporum, the asexual morph is recorded for the first time. Mycosphaerangium quercinum sp. nov. is described as a new species from various Quercus hosts in Europe, where it is shown to be widely distributed. It morphologically and ecologically closely resembles the North American M. tetrasporum, but differs in paraphysis and ascospore morphology and by croziers at its ascus base. The three accepted species of Mycosphaerangium and the two of Neomelanconium are described and illustrated. Mycosphaerangium magnisporum, M. quercinum and M. tetrasporum are recorded to be constantly associated with species of Coryneum, indicating a fungicolous habit, but no evidence for fungal associations has been found in Neomelanconium deightonii and N. gelatosporum.

A New Species

The fern flora of the Seychelles archipelago remains relatively poorly known. Recent projects involving the development of the Seychelles National Herbarium and study of key biodiversity areas have resulted in extensive explorations of the ferns on the granitic islands. Historical literature, newly collected specimens and older collections have been revised for the fern family Hymenophyllaceae as a prelude for a fern checklist, resulting in several discoveries. In Didymoglossum, specimens were found with a very unusual character: exsert sori. Revision of the specimens, including phylogenetic analyses, revealed that these belong to two distinct species: Didymoglossum beccarianum comb. nov. (until now only known from Southeast Asia) and a new species endemic to Seychelles, which is described as D. beaverianum below. The exact identity of the Southeast Asian species required to review a complex of species previously considered synonymous to D. motleyi. As a result, we propose a taxonomic hypothesis where Didymoglossum motleyi is in fact known from the type only (from Borneo); D. beccarianum includes the synonyms Trichomanes cognatum, T. sayeri and T. minutissimum and is widely distributed from Seychelles to the western Pacific Ocean and finally Didymoglossum (Trichomanes) cultratum comb. nov., which is maintained as a separate species (endemic to Fiji and known from the type only). We conclude by emphasizing the main diagnostic characters in this complex of species, including characters that have been neglected in the past.
