Hyphoderma pinicola sp. nov. of H. setigerum complex (Basidiomycota) from Yunnan, China

Abstract

BackgroudHyphoderma setigerum (Fr.) Donk is a white-rot wood-decaying corticoid fungal species. It occurs worldwide from tropical to temperate regions. However, taxonomic studies in recent decades showed that H. setigerum is a species complex with four separate species, before this study.ResultsHyphoderma pinicola sp. nov. was collected on dead wood of Pinus yunnanensis Franch. in the temperate montane belt at 2200–2400 m altitudes, in Yunnan Province of China. Within the H. setigerum complex this new taxon is distinguished by having 2-sterigmate basidia, long basidiospores, and nearly naked septocystidia. A description and illustrations of this new species are provided, along with a key to five species of the H. setigerum complex. Phylogenetic reconstruction based on 5.8S-ITS2 sequences indicated that H. pinicola belongs to the H. setigerum complex and has a separate position within the clade including H. subsetigerum and H. setigerum s.s. Bayesian inference of phylogeny based on two datasets, ITS and 28S nuclear ribosomal DNA sequences, confirmed the independent status of H. pinicola.ConclusionMorphological and phylogenetic studies showed that H. pinicola represents a fifth species of H. setigerum complex.Electronic supplementary materialThe online version of this article (doi:10.1186/s40529-014-0071-5) contains supplementary material, which is available to authorized users.

“…As well as with two sequences from GenBank under H. setigerum from the USA, and clade 5 (Nilsson et al 2003 ) from China and Japan under H. nudicephalum . On the other hand, H. setigerum s.str and H. subsetigerum (clades 7A and 7B) from Nilsson et al ( 2003 ) grouped close to H. pinicola described from China by Yurchenko and Wu ( 2014 ).

“…Based on molecular, morphological and crossing test analyses, Nilsson et al ( 2003 ) concluded that H. setigerum is a species complex and nine taxa exist inside it. Moreover, a succession of studies (Gilbertson and Blackwell 1988 ; Wu 1997 ; Boidin and Gilles 2003 ; Yurchenko and Wu 2014 ) described four more species with this type of cystidia: Hyphoderma nudicephalum from Louisiana, USA, Hyphoderma subsetigerum from Taiwan, Hyphoderma bisetigerum from Madagascar, and Hyphoderma pinicola from China.…”

Further studies should focus on the relationships between the host and Hyphoderma species, as well as trying to better understand the evolutionary directions between plant and Hyphoderma species.…”

“…Alternaria alternata , which is a common dominant species in M, Q, and Y, has the ability to degrade cellulose and lignin (Guillen et al 1987 ; Sharma et al 2016 ). Fusarium solani in M, Mortierella elongata and Hyphoderma setigerum in Q, Nigrospora oryzae and Epicoccum nigrum in Y have been reported to have the ability to degrade lignocellulose (Lozovaya et al 2006 ; Olajuyigbe et al 2016 ; Yao et al 2012 ; Yurchenko and Wu 2014 ).…”
