Three new species of Russulasection Ingratae, found in Guizhou and Jiangsu Provinces, southern China, are proposed: R. straminella, R. subpectinatoides and R. succinea. Photographs, line drawings and detailed morphological descriptions for these species are provided with comparisons against closely-related taxa. Phylogenetic analysis of the internal transcribed spacer (ITS) region supported the recognition of these specimens as new species. Additionally, R. indocatillus is reported for the first time from China and morphological and phylogenetic data are provided for the Chinese specimens.

Three new species of Russula collected from southern China are proposed based on morphological characters and phylogenetic analysis of internal transcribed spacer (ITS) sequences. Russula bubalina sp. nov. is characterized by cinnamon buff to pink pileus with striate margin, interveined and forked lamellae, basidiospores with warty ornamentations not forming reticulum, hymenial cystidia becoming brown in sulphovanillin (SV) and slender terminal cells in suprapellis. R. pseudobubalina sp. nov. is closely related to Russula bubalina in macro-morphology, but it can be recognized by its unforked lamellae, shorter cheilocystidia, bigger basidia and basidiospores with lower ornamentations. Russula subatropurpurea sp. nov. can be recognized by the purplish brown pileus, mild-tasted and white context changing to light purplish red with FeSO4, white and forking lamellae without lamellulae, long hymenial cystidia becoming brown in SV. Both morphological and phylogenetic analysis consistently confirmed the distinct positions of three new species in subg. Heterophyllidia subsection Heterophyllinae.

Three new species of Calocybella, C. lohitha, C. babruka and C. swetha are described from Kerala State, India based on morphology and molecular phylogeny. Comprehensive descriptions of these species are provided along with photo-illustrations and comparisons with phenetically similar and phylogenetically related species. Nuclear ribosomal internal transcribed spacer (ITS) region of the three species were sequenced and analyzed. In addition, nuclear ribosomal large subunit (nrLSU) region of Calocybella swetha was sequenced and used in BLASTn search to find similar sequences. ITS-based phylogenetic analysis using Maximum likelihood (ML) method supported both the novelty of these species and their placement within the genus. The discovery of these three species forms the first record of Calocybella outside Europe.

Suillus marginielevatus sp. nov. and S. triacicularis are reported from Himalayan moist temperate forests of Pakistan in association with conifers. Morphologically S. marginielevatus is close to S. sibiricus, S. granulatus and S. intermedius but it can be distinguished by uplifted pileus margin and curved stipe with no ring at all stages. Phylogenetic analysis of internal transcribed spacer (ITS) region showed that this species form separate clade from other closely related Suillus species. Suillus triacicularis represents a new record for Pakistani mycobiota. Field photographs of fresh basidocarps and line drawings of microcharacters are provided along with phylogenetic tree.

Twenty seven species of Psathyrella have been found in Northeast China. Amongst them, P.conica, P.jilinensis, P.mycenoides and P.subsingeri are described as new species, based on studying morphological characteristics and phylogenetic analyses. Detailed morphological descriptions, line drawings and photographs of the new species are presented. Phylogenetic analysis of the nuclear ribosomal internal transcribed spacer (ITS) region and an identification key to the 27 Psathyrella species occuring in Northeast China are provided.

Russula fanjing is proposed here as a new species based on morphological and molecular evidence. The new species is described and illustrated with photographs and line drawings and compared to related species. Morphologically, R. fanjing (subgenus Russula, section Russula, subsection Russula) is characterized by a medium-sized basidioma, with a vivid red to pastel red areolate pileus, white lamellae occasionally forked near the stipe with lamellulae, a smooth white stipe, basidiospores ornamented with strongly amyloid warts and ridges interconnected by fine lines in an incomplete or complete reticulum, and a pileipellis a typical trichoderm with suprapellis cells composed of short-celled, claw-like branched, lotus-root-like inflated hyphae and dispersed clavate, septate pileocystidia. The phylogenetic analysis of the nucleotide sequences of the internal transcribed spacer (ITS) region provided further evidence that the described species belongs to subsection Russula and represents a new taxon.

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.

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.

Infundibulicybe macrospora, a new species, is described and illustrated from the Himalayan moist temperate forests of Pakistan. The new species can be differentiated from close allies by its reddish orange to light orange pileus, whitish lamellae and stipe, and larger and broader basidiospores. The new species is also supported by molecular phylogenetic analysis inferred from internal transcribed spacer (ITS) region.

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.

Russula subrutilans sp. nov., a new species of Russula is described from southern China. It is unique for having buff pink to light congo-pink pileus, distant ventricose to subventricose lamellae with rare lamellulae, globose to broadly ellipsoid spores with bluntly conical warts forming a partial reticulum, and narrowly clavate to clavate cheilocystidia and pleurocysitidia with variable tips. Phylogenetic relationships among the new species and other closely related species in the genus are inferred based on the internal transcribed spacer (ITS) region.
