Two Laetiporus species, L. ailaoshanensis and L. zonatus spp. nov., are described from southwestern China based on morphological and molecular characters. Laetiporus ailaoshanensis is characterized by orange-yellow to reddish orange pileal surface and cream to buff pores when fresh, azonate to faintly zonate pileus, ovoid to ellipsoid basidiospores (5.0-6.2 × 4.0-5.0 μm), and it has been observed only on Lithocarpus. Laetiporus zonatus is characterized by white to cream pileal surface with buff to clay-buff base when fresh, concentrically zonate basidiocarps, ellipsoid to pyriform or drop-shaped basidiospores (5.8-7.2 × 4.3-5.5 μm), and it has been found only on Quercus. The phylogenetic relationships of all recognized Laetiporus species were inferred from a combined dataset of ITS and nLSU-rDNA sequences, and L. ailaoshanensis and L. zonatus represent two new lineages in this group.
基于形态学和分子特征，在中国西南部描述了两种硫黄多孔菌属物种，即哀牢山硫黄多孔菌和新种环带硫黄多孔菌。哀牢山硫黄多孔菌的特征为新鲜时菌盖表面橙黄色至红橙色，菌孔奶油色至浅黄色，菌盖无环带至有微弱环带，担孢子卵形至椭圆形（5.0 - 6.2 × 4.0 - 5.0μm），且仅在柯属植物上发现。环带硫黄多孔菌的特征为新鲜时菌盖表面白色至奶油色，基部浅黄色至土浅黄色，担子果有同心环带，担孢子椭圆形至梨形或水滴形（5.8 - 7.2 × 4.3 - 5.5μm），且仅在栎属植物上发现。基于ITS和nLSU - rDNA序列的联合数据集推断了所有已确认的硫黄多孔菌属物种的系统发育关系，哀牢山硫黄多孔菌和环带硫黄多孔菌代表了该类群中的两个新谱系。
