Andeimalvaperuviana Dorr & C.Romero, sp. nov., the third Peruvian endemic in a small genus of five species, is described and illustrated from a single collection made at high elevation on the eastern slopes of the Andes. Molecular phylogenetic analyses of nuclear ribosomal ITS sequence data resolve a group of northern species of Andeimalva found in Bolivia and Peru from the morphologically very different southern A.chilensis. The new species bears the largest flowers of any Andeimalva and is compared with Bolivian A.mandonii. A revised key to the genus is presented.

A New Species

The genus Trichoglossum (Geoglossaceae) is characterized by black, clavate, stipitate apothecia with hymenial setae. We collected T. cf. octopartitum from China and a new species of Trichoglossum from Thailand, the latter named as T. septatum. According to morphological examination and molecular phylogenetic analyses of ITS sequence data, T. septatum diverges from other Trichoglossum species. Full descriptions, colour figures, and a phylogenetic tree to show the positions of T. cf. octopartitum and T. septatum are provided, and the two species are compared with allied taxa. The important morphological characteristics of Trichoglossum species are also summarized.

Molecular Phylogenetic Data

Efibula yunnanensis is proposed as a distinct new species based on morphological and molecular phylogenetic data. The species is characterized by an annual growth habit, resupinate basidiomata with smooth, cream to pale brown hymenial surface, a monomitic hyphal system with thin-walled, simple septate generative hyphae and ellipsoid, hyaline, thin-walled, smooth, IKI-, CB-basidiospores. The phylogenetic analyses based on ITS sequence data analyses revealed that E. yunnanensis was sister to a clade comprised E. clarkii and E. gracilis, and then grouped with E. americana and E. tuberculata.

A New Species

A new species, Rhexocercosporidium camporesii was collected from dead branches of Scabiosa maritima (Caprifoliaceae) in Forlì-Cesena, Italy. The new species is characterized by a lack of setae surrounding the apothecia and by fusiform, aseptate ascospores containing multiple guttules. Rhexocercosporidium camporesii has larger asci and ascospores than other species of Rhexocercosporidium. Phylogenetic analyses using a combined gene analysis of LSU and ITS sequence data indicated that the new species belongs to Ploettnerulaceae (Helotiales). A detailed morphological description and illustration of the new species are provided.

Gene Sequence Data

Coloration, gene-sequence data (H3, 12s, 16s), and subtle features in morphology support the description of two new species, both formerly regarded to represent accepted variants of Phimochirus holthuisi s.l. While color in life consistently separates these species from P. holthuisi s.s. and from each other, morphological distinctions are subtle and less than absolute in small specimens, being based on ventral spine counts of walking leg dactyls and relative development of the superior crest on the major chela. Molecular phylogenetic analyses clearly support the separation of sister clades, representing two new species, from P. holthuisi s.s. as well as other congeners available for analysis. Both of the new species are presently known to occur widely throughout the northern Gulf of Mexico, though one occurs more commonly in the northeastern and southeastern Gulf, and may range as far south as Suriname. The other has been taken primarily in the northwestern Gulf, and is not known from outside Gulf waters. While both of the new species appear restricted to relatively deep subtidal waters of the continental shelf, Phimochirus holthuisi s.s. is instead more commonly found in shallow nearshore tropical waters on or near coral reefs. Previous literature reports of P. holthuisi usually represent, at least in part, one or both of these two new species.

The morphology and phylogenetic relationships of a species of Urocystis on Dichelostemma capitatum (Themidaceae, Asparagales) collected in the Tucson Mountains in Arizona, United States, were studied using microscopy and ITS rDNA sequence analyses. This is a first record for smut fungi on hosts from Themidaceae. Molecular phylogenetic analyses based on ITS sequence data revealed its basal position in relation to species on Poaceae. As a result, the smut in leaves of Dichelostemma capitatum is described and illustrated here as a new species, Urocystis cumminsii.

The genus Phillipsia (Sarcoscyphaceae) is characterized by large, bright-coloured, sub-stipitate apothecia, sub-operculate asci and asymmetrical ascospores with longitudinal striations. Morphological and phylogenetic studies were carried out on new collections of Phillipsia from China and Thailand. Phillipsia subpurpurea are recorded from China and Phillipsia gelatinosa from Thailand is introduced as a new species to science. Our new collections are confirmed to be divergent from other species of Phillipsia based on morphological examination and molecular phylogenetic analyses of ITS and LSU sequence data. Descriptions and figures are provided for the taxa which are also compared with allied taxa.

AbstractDespite recent efforts to accelerate exploration and species description, the diversity of high Andean frogs remains highly underestimated. We report high levels of species diversity in direct-developing frogs or terraranas inhabiting the wet puna and adjacent cloud forests of the Amazonian versant of the Andes in Bolivia and Peru. Descriptive evidence of external morphology, distribution patterns and molecular phylogenetic analyses support the existence of nine unnamed species in two clades, which represents a 30% increase in species diversity for those clades. The relationships of these species and their relatives in Holoadeninae are tested using nuclear and mitochondrial genes for 159 terminals representing the 11 genera in this subfamily and 25 species of previously unknown relationships. Our results corroborate species monophyly in all but three cases and support the monophyly of all Holoadeninae genera, albeit the position of some differs between analyses. We propose a new genus (Microkayla gen. nov.) for the clade containing all Bolivian species formerly in Psychrophrynella plus five species from southern Peru. The new genus is monophyletic and supported by anatomical synapomorphies. Psychrophrynella is re-diagnosed and redefined to include three species from the Andes of southern Peru. We discuss the taxonomic instability associated with Noblella and Psychrophrynella due to the fact that the type species of both genera share a number of traits that support a close relationship. We also name and describe three new species of Bryophryne and two of Microkayla from Peru, provide baseline data for the future description of four Bolivian species of Microkayla, and describe the unknown mating calls of two species. Our results support that the grasslands of the Amazonian versant of the Andes harbour a large diversity of species with small altitudinal and horizontal distributions that replace each other along a latitudinal axis. These species belong to different lineages whose closest relatives are forest species, often from distant parts of the continent. These patterns suggest that high Andean environments were colonized several times independently by species with forest ancestors and which radiated into a multitude of species with remarkably similar ecomorphologies. The extent of these radiations remains obscured by a still rudimentary knowledge of species diversity due to insufficient fieldwork and taxonomic research.

A New Species

Colletotrichum has numerous host range and distribution. Its species are important plant pathogens, endophytes and saprobes. Colletotrichum can cause regular or irregular depressions and necrotic lesions in the epidermal tissues of plants. During this research Colletotrichum specimens were collected from Mengyin County, Shandong Province, China. A multi-locus phylogenetic analysis of ITS, GAPDH, CHS-1, ACT, TUB2, CAL and GS sequence data combined with morphology, revealed a new species and two known species, viz. C. mengyinense sp. nov., C. gloeosporioides and C. pandanicola, belonging to the C. gloeosporioides species complex. The new species is described and illustrated in this paper and compared with taxa in the C. gloeosporioides species complex.
