Two New Species

Gyroporus species with cyanescent oxidation reactions were investigated, based on morphology and phylogenetic analysis of DNA sequences from the nuclear ribosomal large subunit (nrLSU), the nuclear ribosomal internal transcribed spacer (ITS) and the mitochondrial adenosine triphosphate ATP synthase subunit 6 (atp6). Three species, including two new species, namely G. alpinus and G. flavocyanescens and one previously-described species, namely G. brunneofloccosus, are revealed from China. Collections formerly reported from China as “G. cyanescens” are either G. alpinus or G. flavocyanescens. The new species are documented and illustrated in detail, while the concept of G. brunneofloccosus is refined with additional recently-collected materials. Additionally, the cyanescent species G. pseudomicrosporus, previously described from China, is shown to be a member of the genus Gyrodon, based on re-examination of the type specimen. A key to the cyanescent Gyroporus species from China is provided.

During survey on rock-inhabiting fungi from karst habitats in Guizhou, China, two new species in Cyphellophora were discovered and identified. Phylogenetic analysis based on combined sequences of the nuclear large subunit (nucLSU) and internal transcribed spacer (ITS) region of ribosomal DNA revealed that the tested isolates, clustered into two clades that well affiliated in the genus of Cyphellophora. Morphological characteristics were also supported the estabolishment of the new species. Herewith Cyphellophora botryose sp. nov. and Cyphellophora guizhouensis sp. nov. were described and their differences from closely related species were discussed.

Two fresh collections of Discosia were made from dead leaves of Fagus sylvatica in Italy. As these collections could not be cultured, the fruiting bodies were directly used for sequencing using a Forensic DNA Extraction Kit. Based on analyses of the concatenated internal transcribed spacer regions of the nrDNA operon (ITS) and large subunit rDNA (LSU) gene sequences, as well as morphological characters, the fresh collections are introduced as two new species, namely D. italica and D. fagi. Phylogenetically, these two species are distinct from all other Discosia species. Morphologically, D. italica is somewhat similar with D. fagi, but can be distinguished using dimension of conidiomata and conidiogenous cells. Descriptions and illustrations of the new taxa are provided herein.

Two new species of Dentipellis are described from China based on morphological characteristics and molecular data. Dentipellis longiuscula is characterized by annual, resupinate hydnoid basidiomata with moderately long spines, rough basidiospores (5–6 × 3–3.6 µm) and absence of gloeoplerous hyphae and gloeocystidia. Dentipellis tropicalis is characterized by hydnoid basidiomata with numerous gloeocystidia presenting in hymenium, and minutely rough basidiospores (5–5.5 × 2.5–3.2 µm). Phylogenetic analysis based on the internal transcribed spacer (ITS) and nuclear large subunit ribosomal (nLSU) RNA gene regions confirmed the affinity of the new species in Dentipellis and indicated their relationships with other species in the genus.

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.

A new polypore, Ceriporia albomellea, collected from tropical China, is described and illustrated based on morphological characteristics and molecular evidence. It is characterized by thin, resupinate basidiome with a white subiculum, cottony margin, white to cinnamon-buff pores, clavate cystidia and oblong-ellipsoid basidiospores measured as 3.1–3.8 × 1.7–2 µm. Phylogenetic analysis based on the internal transcribed spacer (ITS) regions and nuclear large subunit (nLSU) ribosomal RNA gene regions supported C. albomellea as a distinctive species belonging to Ceriporia.

Species of Clavaria (Clavariaceae, Agaricales) collected from China were studied using morphological and molecular methods. Two species, C. griseolilacina and C. sinensis were described as new species; both possess branched and pale purple-tinged fruit bodies. However, the former possess a few branched, while the latter is profusely branched. The phylogenetic analysis based on the internal transcribed spacer (ITS) sequences confirmed the distinctions between these two new species and their close relationships with C. rubicundula and C. fumosa in the genus. An evolutionary tendency in genus Clavaria was discussed. Additionally, morphological features of the two new species were described in detail and were illustrated with line drawings and photographs. Holotypes of the new species are deposited in the Mycological Herbarium of Hunan Normal University (MHHNU). The ITS sequences generated in this study were deposited in GenBank. A key is provided for the known Clavaria species in China.

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.

The nuclear ribosomal internal transcribed spacer region (ITS), a portion of the nuclear ribosomal large subunit (nLSU) and a portion of the nuclear second-largest subunit of RNA polymerase II (rpb2) gene of this species were sequenced and analyzed. Phylogenetic analysis of rpb2 sequences confirmed both the novelty of the species and its placement within the Pseudosperma clade.

The genus Hygrophorus is poorly studied from Asia. From Pakistan, only one species has been reported so far. Two new species in the genus have been collected from Himalayan oak forests of Pakistan. Hygrophorusalboflavescens (section Pudorini, subgenus Colorati) is characterised by its pure white, centrally depressed pileus, occurrence of white stipe with yellow patches at lower half and broader (4.98 μm) basidiospores. Hygrophorusscabrellus (section Hygrophorus, subgenus Hygrophorus) is characterised by its yellowish-green stipe with white apex that has fine scales on the entire stipe, an off-white pileus with dark green and greyish fibrils, ovoid to ellipsoid basidiospores and clavate 4-spored basidia. Macro- and micromorphological descriptions have revealed that both these taxa are not yet described. Phylogenetic estimation based on DNA sequences from the internal transcribed spacer (ITS) region and large subunit (LSU) of the nuclear ribosomal DNA (rDNA) genes, is congruent with the morphological characters that help to delimit these as new species of Hygrophorus. Allied taxa are also compared.
