A New Species

A new species of agaricomycetes, Clitopilus lampangensis, is described based on collections from northern Thailand. This species was distinguished from previously described Clitopilus species by its pale yellow to grayish yellow pileus with the presence of wider caulocystidia. Molecular phylogenetic analyses, based on the data of the internal transcribed spacers (ITS) and the large subunit (LSU) of the nuclear ribosomal DNA, and the second largest subunit of RNA polymerase II (rbp2) genes, also support the finding that C. lampangensis is distinct from other species within the genus Clitopilus. A full description, color photographs, illustrations and a phylogenetic tree showing the position of C. lampangensis are provided.

A New Species

A new species of agaricomycetes, Xanthagaricus thailandensis, is described based on collections from northern Thailand. This species is characterized by its medium-sized basidiomata, pale orange pileus, a pseudoparenchymatous structure of the squamules on the pileal surface, subcylindrical to clavate caulocystidia and brownish yellow basidiospores. It is clearly distinguished from the previously described Xanthagaricus species by narrow caulocystidia. Molecular phylogenetic analyses, based on a combination of the internal transcribed spacers (ITS) and the large subunit (LSU) of the nuclear ribosomal DNA, also support the finding that X. thailandensis is distinct from other known species within the genus Xanthagaricus. A full description, color photographs, illustrations and a phylogenetic tree showing the position of X. thailandensis are provided.

A new saprophytic fungus, Pleurotus sirindhorniae, is described based on collections from northern Thailand. This species is characterized by greyish yellow to olive brown pileus, ellipsoid to elongate basidiospores and clavate to mucronate cheilocystidia. It is distinguished from the previously described Pleuotus species by its distinct morphological characteristics. Molecular phylogenetic analyses of the large subunit (LSU) and internal transcribed spacers (ITS) of the nuclear ribosomal DNA (rDNA), the translation elongation factor 1-alpha (tef1) and the RNA polymerase II largest subunit (rpb1) genes also support P. sirindhorniae as a distinct new species within the genus Pleurotus. A full description, color photographs, illustrations and a phylogenetic tree to show the position of P. sirindhorniae are provided.

Taxonomic and phylogenetic studies of Chlorophyllum were carried out on the basis of morphological differences and molecular phylogenetic analyses. Based on the phylogeny inferred from the internal transcribed spacer (ITS), the partial large subunit nuclear ribosomal DNA (nrLSU), the second largest subunit of RNA polymerase II (rpb2) and translation elongation factor 1-α (tef1) sequences, six well-supported clades and 17 phylogenetic species are recognised. Within this phylogenetic framework and considering the diagnostic morphological characters, two new species, C.africanum and C.palaeotropicum, are described. In addition, a new infrageneric classification of Chlorophyllum is proposed, in which the genus is divided into six sections. One new combination is also made. This study provides a robust basis for a more detailed investigation of diversity and biogeography of Chlorophyllum.

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.

A new species, namely Chlorociboria herbicola, is discovered on herbaceous stems in central China. Morphologically, the new fungus is distinctive by the combination of light blue-green apothecia, rectangular cells in ectal excipulum, and elongate-ellipsoidal ascospores with rounded ends. Phylogenetic analyses of the internal transcribed spacer and large subunit of nuclear ribosomal DNA sequences confirm its ascription in Chlorociboria and distinction from the known species of the genus.

This species is characterized by basauxic conidiophores and dark brown to blackish brown α and β conidia. It can be distinguished from previously described Spegazzinia species by the spine length of the α conidia and the size of the β conidia. Multi-gene phylogenetic analyses of the small subunit (SSU), large subunit (LSU) and internal transcribed spacers (ITS) of the nuclear ribosomal DNA (rDNA) and the translation elongation factor 1-alpha (tef1) genes also support S. camelliae is a distinct new species within Spegazzinia.

Gerhardtia sinensis, as a new species discovered from southern China, is described, illustrated and compared with morphologically similar and phylogenetically related species. Morphologically, it is characterized by its white to yellowish or partially pale yellow pileus with faint striae, subdistant to fairly distant lamellae with intervenose veins, and slightly verruculose basidiospores (4.7–)5.2–6.2(–6.6) × (2.5–)3.0–3.4(–3.8) μm in size. Molecular phylogenetic analyses of the new species and related taxa are performed based on the sequences of nuclear ribosomal large subunit (nrLSU) and nuclear ribosomal internal transcribed spacer (ITS).

A New Species

Abstract A new species of the genus Plagiorhynchus Lühe, 1911 from the intestine of the long-billed curlew (Numenius americanus) from northern Mexico is described. Plagiorhynchus (Plagiorhynchus) aznari n. sp. is morphologically distinguished from other congeneric species from the Americas by having a trunk expanded anteriorly and a cylindrical proboscis, armed with 19 longitudinal rows of hooks, with 14–15 hooks each row. Nearly complete sequences of the small subunit and large subunit of the nuclear ribosomal DNA of the new species were determined and compared with available sequences from GenBank. Phylogenetic analyses inferred from the two molecular markers consistently showed that P. (Plagiorhynchus) aznari n. sp. is closely related to P. (Plagiorhynchus) allisonae, and this clade is sister to a clade formed by P. (Prosthorhynchus) transversus and P. (Prosthorhynchus) cylindraceus from Plagiorhynchidae. The new species represents the second record of the genus in Mexico and the fourth species in the Americas. The phylogenetic relationships among the members of the order Polymorphida in this study provide significant insights into the evolution of ecological associations between parasites and their definitive hosts. Our analyses suggest that the colonization of marine mammals, fish-eating birds and waterfowl in Polymorphidae might have occurred independently, from a common ancestor of Centrorhynchidae and Plagiorhynchidae that colonized terrestrial birds and mammals.
