Species diversity of pathogenic wood-rotting fungi (Agaricomycetes, Basidiomycota) in China.

Wood-rotting basidiomycetes have been investigated in the Chinese forest ecosystem for the past 30 years. Two hundred and five pathogenic wood-decayers belonging to 9 orders, 30 families, and 74 genera have been found in Chinese native forests, plantations, and gardens. Seventy-two species (accounting for 35% of the total pathogenic species) are reported as pathogenic fungi in China for the first time.

A contribution to Porogramme (Polyporaceae, Agaricomycetes) and related genera.

The polypores with shallow pores from tropical Asia and America are studied. Our molecular phylogeny based on the internal transcribed spacer (ITS), the large subunit nuclear ribosomal RNA gene (nLSU), the translation elongation factor 1-α gene (TEF1), and the largest subunit of RNA polymerase II (RPB1) demonstrates six clades are formed among Porogramme and related genera. Two new genera, Cyanoporus and Pseudogrammothele, are established, and the six clades represent Porogramme, Cyanoporus, Grammothele, Epithele, Theleporus, and Pseudogrammothele, respectively.

Two new species of (Polyporales, Basidiomycota) in western China.

Two new species of , and , are described from western China. Phylogeny based on a six-gene dataset (ITS + nLSU + nSSU + mtSSU + TEF1 + RPB2) demonstrates that samples of the two species form two independent lineages within the clade of and are different in morphology from the existing species of . is characterized by its annual and resupinate basidiocarps with angular to irregular pores of 2-3 mm each and oblong ellipsoid to cylindrical basidiospores measuring 9-12 × 4.

A new contribution to sensu lato: Six new species and three new combinations.

sensu lato has recently been intensively studied in China and South America, and four independent clades representing four genera have been recognized phylogenetically. In this study, more samples, mostly from subtropical and tropical Asia, Oceania, and East Africa, are analyzed. A phylogeny based on a 4-gene dataset of sequences (ITS + nLSU + mtSSU + ) has confirmed the presence of four genera in sensu lato: , and sensu stricto.

Outline, Divergence Times, and Phylogenetic Analyses of Trechisporales (Agaricomycetes, Basidiomycota).

Phylogenetic analyses inferred from the nuc rDNA ITS1-5.8S-ITS2 (ITS) data set and the combined 2-locus data set [5.8S + nuc 28S rDNA (nLSU)] of taxa of Trechisporales around the world show that family forms a monophyletic lineage within Trechisporales.

Two new brown rot polypores from tropical China.

Brown-rot fungi are types of fungi that selectively degrade cellulose and hemicellulose from wood and are perhaps the most important agents involved in the degradation of wood products and dead wood in forest ecosystem. Two new brown-rot species, collected from southern China, are nested within the clades of sensu stricto and sensu stricto, respectively. Their positions are strongly supported in the Maximum Likelihood phylogenetic tree of the concatenated the internal transcribed spacer (ITS) regions, the large subunit of nuclear ribosomal RNA gene (nLSU), the small subunit of nuclear ribosomal RNA gene (nuSSU), the small subunit of mitochondrial rRNA gene (mtSSU), the largest subunit of RNA polymerase II (RPB1), the second largest subunit of RNA polymerase II (RPB2) and the translation elongation factor 1-α gene (TEF1) sequences.

Two new species of Hymenochaetaceae on from tropical China.

Two new wood-rotting fungi in the family Hymenochaetaceae, and , are described and illustrated from tropical China based on morphological characteristics and molecular data. It is worth to mention that both of them grow on which is a kind of angiosperm tree distributed in tropical regions. is characterised by perennial, pileate, triquetrous basidioma with yellowish brown fresh pores which becoming honey yellow with silk sheening upon drying, a dimitic hyphal system in trama and monomitic in context, and subglobose basidiospores measuring 4.
