Two new wood-inhabiting fungi sp. nov. and sp. nov. in the Meruliaceae family are described and illustrated from southwestern China based on molecular and morphological evidence. The characteristics of include annual, resupinate basidiomata, the absence of cystidia and cystidioles, oblong ellipsoid basidiospores of 5-6 × 2.4-3 μm, and growth on rotten gymnosperm wood in the east Himalayas. Its basidiomata change drastically upon drying, from being a light-coloured, juicy, papillose-to-wrinkled hymenophore, to a dark-coloured, corky-to-gelatinous, and more or less smooth hymenophore. The characteristics of include annual, resupinate basidiomata, a hydnoid hymenophore, 2-3 spines per mm, the presence of tubular cystidia of 20-25 × 3-3.5 µm, oblong ellipsoid basidiospores of 4.4-5.2 × 2.1-3 μm, and growth on angiosperm wood in tropical forests in the southern Yunnan Province. The phylogenetic analyses based on the combined 2-locus dataset (ITS1-5.8S-ITS2 (ITS) + nuclear large subunit RNA (nLSU)) confirm the placement of two new species, respectively, in and s. lato. Phylogenetically, the closely-related species to these two new species are discussed.
基于分子和形态学证据，在中国西南部描述并图示了多孔菌科的两种新的木生真菌新物种和新物种。的特征包括担子果一年生、平伏，无囊状体和拟囊状体，担子孢子长椭圆形，大小为5-6×2.4-3μm，生长在东喜马拉雅地区的腐烂裸子植物木材上。其担子果干燥后变化极大，从浅色、多汁、具乳头状至皱状的子实层体，变为深色、软木质至凝胶状且或多或少平滑的子实层体。的特征包括担子果一年生、平伏，具齿状子实层体，每毫米有2-3个刺，有20-25×3-3.5μm的管状囊状体，担子孢子长椭圆形，大小为4.4-5.2×2.1-3μm，生长在云南省南部热带森林的被子植物木材上。基于联合的双基因数据集（ITS1-5.8S-ITS2（ITS）+核糖体大亚基RNA（nLSU））的系统发育分析分别证实了这两个新物种在和广义范围内的分类地位。从系统发育角度讨论了与这两个新物种亲缘关系密切的物种。
