Two new corticioid fungi in the family Phanerochaetaceae, and , are described and illustrated from Southwest China based on morphological characteristics and molecular data. is characterized by annual, effused, inseparable basidiocarps from substrate, ivory white to cream hymenial surface when juvenile, buff to yellowish brown with age, buff in KOH, a monomitic hyphal system, smooth cystidia, and ellipsoid basidiospores measuring 4.8-6 × 2.5-3.8 µm. is characterized by annual, effused, easily separable basidiocarps from substrate, buff-yellow to clay-pink fresh hymenial surface becoming cream to buff upon drying, violet in KOH, a monomitic hyphal system, encrusted cystidia, and ellipsoid basidiospores measuring 3-4 × 2.2-3 µm. The phylogenetic analyses based on ITS + nLSU rDNA sequences confirm the placement of the two new species, respectively, in the clade and the clade of Phanerochaetaceae. Phylogenetically related and morphologically similar species to these two new species are discussed.
本文描述并图示了来自中国西南地区的两个隶属于栓菌科的新皮壳菌属真菌, 和 。 具有一年生、平展、无分隔的从基质长出的担子果,幼年时为乳白色至奶油色的菌盖表面,成熟后为浅黄色至黄褐色,在 KOH 中呈浅黄色,单型的菌丝系统,光滑的囊状体,以及 4.8-6×2.5-3.8µm 的椭圆形担孢子。 具有一年生、平展、易从基质上分离的担子果,新鲜时的菌盖表面为浅黄色至土黄色,干燥后呈奶油色至浅黄色,在 KOH 中呈紫罗兰色,单型的菌丝系统,被覆的囊状体,以及 3-4×2.2-3µm 的椭圆形担孢子。基于 ITS+nLSU rDNA 序列的系统发育分析证实了这两个新种分别位于皮壳菌属和栓菌科的 分支中。讨论了与这两个新种亲缘关系较近且形态相似的相关物种。
