摘要

木栖真菌存在于活树、死树枝干的脱皮木材以及人造木制品中,作为重要的分解者群体在森林生态系统中发挥着重要作用。本研究结合形态特征和分子证据,提出了两个新的木栖真菌类群,即云南烛菌(Candelabrochaete yunnanensis)和中华烛菌(Hyphodermella sinensis)。Candelabrochaete yunnanensis 的特征是基部具粉红色至褐色的醋状菌膜表面,单生菌丝系统具单隔生菌丝,存在圆柱形的隔囊和椭圆形的基生孢子(4-5 × 2.5-3 µm)。Hyphodermella sinensis 的特征是膜质基生菌体,菌膜表面为白色或略带灰色,单生菌系带有夹生菌丝,存在棍棒状囊胞体和椭圆形基生孢子(4-6 × 3-4 µm)。根据 ITS+nLSU 序列推断出的系统发生树显示,云南串珠草属(Candelabrochaete yunnanensis)被归入多孔菌目中的 Irpicaceae 科,与非洲串珠草属(C. africana)有密切的亲缘关系;中国串珠草属(Hyphodermella sinensis)被归入串珠草属(Hyphodermella genus),并被归入 Phanerochaetaceae 科,与 H. aurantiaca 和 H. zixishanensis 有亲缘关系。

Molecular phylogeny and morphology reveal two new wood-inhabiting fungal species (Basidiomycota) from China
Wood-inhabiting fungi are found in living trees, decorticated wood of dead tree branches and trunks as well as manufactured wood products, and play an important role in forest ecosystems as an important group of decomposers. In this present study, two new wood-inhabiting fungal taxa, Candelabrochaete yunnanensis and Hyphodermella sinensis are proposed based on a combination of the morphological features and molecular evidence. Candelabrochaete yunnanensis is characterized by the farinaceous basidiomata with the flesh-pinkish to brownish vinaceous hymenial surface, a monomitic hyphal system with simple-septate generative hyphae, presence of the cylindrical septocystidia and ellipsoid basidiospores (4–5 × 2.5–3 µm). Hyphodermella sinensis is characterized by the membranaceous basidiomata having the white to slightly greyish hymenial surface, a monomitic hyphal system with clamp generative hyphae, presence of the clavate cystidia and ellipsoid basidiospores (4–6 × 3–4 µm). The phylogenetic tree inferred from ITS+nLSU sequences revealed that Candelabrochaete yunnanensis was nested into the family Irpicaceae within the order Polyporales, in which it was closely related to the species C. africana; Hyphodermella sinensis grouped into the genus Hyphodermella and clustered into the family Phanerochaetaceae, in which it grouped with H. aurantiaca and H. zixishanensis.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
