Hypomyces is a large genus of fungicolous fungi, parasitising the fruiting bodies of Agaricales, Boletales, Helotiales, Pezizales and Polyporales. Hypomyces currently comprises of 147 species widely distributed in Australia, China, France, Germany, Italy, Japan, North America, Sri Lanka, Thailand and UK. Amongst them, 28 species have been recorded in China. Hypomyces pseudolactifluorum sp. nov., growing on the fruiting bodies of Russula sp. in subsect. Lactarioideae and collected from Yunnan, China, is described with illustrations and molecular phylogenetic data (combined ITS, LSU, TEF1-α and RPB2 sequence dataset). The new species is characterised by semi-immersed to immersed perithecia and fusiform, apiculate and verrucose ascospores. We also review the species diversity of the genus Hypomyces in China.

A New Species

Conocybe punjabensis sp. nov., a species belonging to the saprobic family Bolbitaceae, is illustrated and described from Pakistan based on morphology and molecular evidence. The species can be distinguished on the basis of medium-sized fruiting bodies, a pileus with a dark brown central disc, a fibrillose stipe, forked lamellae near pileus margin, ellipsoid angular basidiospores with an apical germ pore, cheilocystidia and pleurocystidia varying from catenulate, lecythiform to clavate, and lecythiform caulocystidia. Molecular phylogenetic analysis of the nuclear ribosomal ITS region also supports the recognition of this new species in Conocybe. Detailed descriptions, photographs, illustrations and comparison with allied taxa are given.

The Australasian spiny trapdoor spiders of the family Idiopidae (subfamily Arbanitinae) are revised at the generic level, using a multi-locus molecular phylogenetic foundation and comprehensive sampling of all known lineages. We propose a new family- and genus-group classification for the monophyletic Australasian fauna, and recognise 10 genera in four tribes. The Arbanitini Simon includes Arbanitis L. Koch, 1874 (61 species), Blakistonia Hogg, 1902 (one species) and Cantuaria Hogg, 1902 (43 species). The Aganippini Simon includes Bungulla Rix, Main, Raven & Harvey, gen. nov. (two species), Eucanippe Rix, Main, Raven & Harvey, gen. nov. (one species), Eucyrtops Pocock, 1897 (two species), Gaius Rainbow, 1914 (one species) and Idiosoma Ausserer, 1871 (14 species). The Cataxiini Rainbow and Euoplini Rainbow include just Cataxia Rainbow, 1914 (11 species) and Euoplos Rainbow, 1914 (12 species), respectively. Two distinctive new genera of Aganippini are described from Western Australia, and several previously valid genera are recognised as junior synonyms of existing genus-group names, including Misgolas Karsch, 1878 (= Arbanitis; new synonymy), Aganippe O. P.-Cambridge, 1877 (= Idiosoma; new synonymy) and Anidiops Pocock, 1897 (= Idiosoma; new synonymy). Gaius stat. rev. is further removed from synonymy of Anidiops. Other previously hypothesised generic synonyms are supported by both morphology and molecular phylogenetic data from 12 genes, including the synonymy of Neohomogona Main, 1985 and Homogona Rainbow, 1914 with Cataxia, and the synonymy of Albaniana Rainbow & Pulleine, 1918, Armadalia Rainbow & Pulleine, 1918, Bancroftiana Rainbow & Pulleine, 1918 and Tambouriniana Rainbow & Pulleine, 1918 with Euoplos. At the species level, the identifications of Eucy. latior (O. P.-Cambridge, 1877) and I. manstridgei (Pocock, 1897) are clarified, and three new species are described: Bungulla bertmaini Rix, Main, Raven & Harvey, sp. nov., Eucanippe bifida Rix, Main, Raven & Harvey, sp. nov. and Idiosoma galeosomoides Rix, Main, Raven & Harvey, sp. nov., the latter remarkable for its phragmotic abdominal morphology. The Tasmanian species Mygale annulipes C. L. Koch, 1842 is here transferred to the genus Stanwellia Rainbow & Pulleine, 1918 (family Nemesiidae), comb. nov., Arbanitis mestoni Hickman, 1928 is transferred to Cantuaria, comb. nov. and Idiosoma hirsutum Main, 1952 is synonymised with I. sigillatum (O. P.-Cambridge, 1870), new synonymy. In addition to the morphological synopses and an illustrated key to genera, molecular diagnoses are presented for all nominal taxa, along with live habitus and burrow images to assist in field identification. The Australasian idiopid fauna is highly diverse, with numerous new species known from all genera. As a result, this study provides a taxonomic and nomenclatural foundation for future species-level analyses, and a single reference point for the monographic documentation of a remarkable fauna. http://zoobank.org/?lsid=urn:lsid:zoobank.org:pub:BACE065D-1EF9-40C6-9134-AADC9235FAD8

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.

Molecular Phylogenetic Data

A new species, Amanita glarea, is described and illustrated from Pakistan. Molecular phylogenetic data derived from internal transcribed spacer (ITS) and nuclear ribosomal large subunit (LSU) regions along with morphological characters make it distinct from other currently known Amanita species. Amanita glarea is characterized by a grayish brown, slightly umbonate, pileus having universal veil remnants and striate margins, a long ringless stipe with a saccate volva bearing yellowish brown patches on the verrucose surface, inamyloid globose to subglobose basidiospores, and a filamentous pileipellis with some inflated round to elongated cells. Phylogenetic analysis of nuclear ribosomal ITS and LSU nucleotide sequences resolve A. glarea with other taxa in Amanita section Vaginatae.

Three New Species

Species diversity of Micropsalliota in China remains poorly known, especially in southwestern China, a hotspot of biodiversity. Based on morphological characteristics and molecular phylogenetic analyses using ITS and nrLSU sequences, three new species named Micropsalliota delicatula, M. dentatomarginata and M. digitatocystis are introduced from China. Phylogenetc analyses results indicated the unique phylogenetic positions of three new species in Micropsalliota. Full descriptions, photo plates, illustrations and a phylogenetic tree to show the placement of three new species are presented.

Molecular Phylogenetic Data

The Cape Floristic Region is exceptionally species-rich both for its area and latitude, and this diversity is highly unevenly distributed among genera. The modern flora is hypothesized to result largely from recent (post-Oligocene) speciation, and it has long been speculated that particular species-poor lineages pre-date this burst of speciation. Here, we employ molecular phylogenetic data in combination with fossil calibrations to estimate the minimum duration of Cape occupation by 14 unrelated putative relicts. Estimates vary widely between lineages (7–101 Myr ago), and when compared with the estimated timing of onset of the modern flora's radiation, it is clear that many, but possibly not all, of these lineages pre-date its establishment. Statistical comparisons of diversities with lineage age show that low species diversity of many of the putative relicts results from a lower rate of diversification than in dated Cape radiations. In other putative relicts, however, we cannot reject the possibility that they diversify at the same underlying rate as the radiations, but have been present in the Cape for insufficient time to accumulate higher diversity. Although the extremes in diversity of currently dated Cape lineages fall outside expectations under a constant underlying diversification rate, sampling of all Cape lineages would be required to reject this null hypothesis.
