A new species of Xylaria is described based on morphological characters of both sexual and asexual morphs, and molecular data based on nuclear rDNA internal transcribed spacer, α-actin, β-tubulin and RNA polymerase subunit II sequences. Xylaria aurantiorubroguttata is characterized by the presence of both upright, cylindrical, long-stipitate and globose to subglobose, short-stipitate stromata, immature stromatal stages producing at first orange and then red drops, and ascospores with a slightly oblique, straight half spore-length germ slit. We provide also new morphological descriptions for X. haemorrhoidalis (holotype) and X. anisopleura (isosyntype), two Xylaria species belonging to X. polymorpha complex together with X. aurantiorubroguttata.
基于有性和无性形态的形态特征以及基于核糖体DNA内部转录间隔区、α-肌动蛋白、β-微管蛋白和RNA聚合酶亚基II序列的分子数据，描述了炭角菌属的一个新物种。橘红滴斑炭角菌的特征是既有直立、圆柱形、具长柄的子座，也有球形至近球形、具短柄的子座，未成熟的子座阶段最初产生橙色然后是红色液滴，以及具稍倾斜、直的半孢子长度萌发缝的子囊孢子。我们还提供了痔状炭角菌（主模式）和异形炭角菌（等模式）的新形态描述，这两种炭角菌与橘红滴斑炭角菌一起属于多形炭角菌复合体。
