Mushrooms in the basidiomycete family Boletaceae are ecologically and economically very important.However,due to the morphological complexity and the limited phylogenetic information on the various species and genera of this fungal family,our understanding of its systematics and evolution remains rudimentary.In this study,DNA sequences of four genes(nrLSU,tef1-α,rpb1,and rpb2)were newly obtained from ca.200 representative specimens of Boletaceae.Our phylogenetic analyses revealed seven major clades at the subfamily level,namely Austroboletoideae,Boletoideae,Chalciporoideae,Leccinoideae,Xerocomoideae,Zangioideae,and the Pulveroboletus Group.In addition,59 genus-level clades were identified,of which 22 were uncovered for the first time.These 22 clades were mainly placed in Boletoideae and the Pulveroboletus Group.The results further indicated that the characters frequently used in the morphology-based taxonomy of Boletaceae,such as basidiospore ornamentation,the form of the basidioma,and the stuffed pores each had multiple origins within the family,suggesting that the use of such features for high-level classification of Boletaceae should be de-emphasized and combined with other characters.

t Coelomycetous fungi are an artificial taxonomic group which produce conidia inside a cavity i.***.conidiomata.Coelomycetes comprise about,1000 genera and 7000 species,which can be endophytic,pathogenic or saprobic.Traditional classification of coelomycetes was previously based on morphology,such as the shape of conidiomata and mode of conidiogenesis,while it was treated as a distinct group i.e.Deuteromycotina.Sequence based taxonomic studies has been used to accommodate asexual fungi in a natural classification system,resolve generic boundaries of polyphyletic genera and species complexes,as well as establish asexual-sexual links.Nevertheless,most of genera lack sequence data,thus,morphology based identification is still important when introducing new genera or species.In this paper we illustrate,describe,and provide taxonomic notes for 235 dematiaceous coelomycetous genera,including five new genera viz.Apiculospora,Didymellocamarosporium,Melanocamarosporium,Melnikia and Paulkirkia.Phylogenetic analyses of combined sequence data are provided to show placements of dematiaceous coelomycetes in Dothideomycetes,Leotiomycetes and Sordariomycetes.One-hundred and fifty-two(65%)of genera have sequence data,thus,their taxonomic placement in a natural classification system,is listed as an outline.However,83 genera still lack sequence data,hence,they are treated as Ascomycota,genera incertae sedis.In addition,separate analyses are provided where better taxonomic resolution is needed.
