Three new species of Phylloporia from tropical China are described in this study: P. manglietiae, P. pendula, and P. pseudopectinata. Phylloporia manglietiae is characterized by triquetrous to ungulate basidiomata, with 6-8 pores/mm, a monomitic to dimitic hyphal system, and broadly ellipsoidal basidiospores, 3-3.5 × 2-2.5 μm. Phylloporia pendula has small, imbricate, and pendent basidiomata, with 7-9 pores/mm, a dimitic hyphal system, and broadly ellipsoidal basidiospores, 3.5-4 × 2.5-3 μm. Phylloporia pseudopectinata differs from other species of Phylloporia by its applanate basidiomata, with 8-9 pores/mm, a dimitic hyphal system, and subglobose basidiospores, 3-3.5 × 2-3 μm. Phylogenetic analyses, based on sequences from the D1-D2 domains of the 28S gene and the internal transcribed spacer (ITS) region (ITS1-5.8S-ITS2 = ITS) of the nuc rDNA, support the classification of the three new species in Phylloporia.
木莲层孔菌、垂悬层孔菌和拟梳状层孔菌。木莲层孔菌的特征是担子果三棱形至蹄形，每毫米有6 - 8个孔，菌丝系统单系至二系，担孢子宽椭圆形，3 - 3.5×2 - 2.5μm。垂悬层孔菌有小的、覆瓦状且下垂的担子果，每毫米有7 - 9个孔，菌丝系统二系，担孢子宽椭圆形，3.5 - 4×2.5 - 3μm。拟梳状层孔菌与其他层孔菌属物种的区别在于其扁平的担子果，每毫米有8 - 9个孔，菌丝系统二系，担孢子近球形，3 - 3.5×2 - 3μm。基于28S基因的D1 - D2结构域和核糖体DNA的内转录间隔区（ITS）区域（ITS1 - 5.8S - ITS2 = ITS）序列的系统发育分析支持将这三个新物种归入层孔菌属。
