摘要

根据有性和无性形态的形态特征，以及基于核 rDNA 内部转录间隔、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 Xylaria 的一个新种。Xylaria aurantiorubroguttata 的特征是具有直立、圆柱形、长柄和球形至近球形、短柄的基质，未成熟基质阶段先产生橙色、后产生红色的液滴，升华孢子具有略微倾斜、直的半孢子长度胚芽裂缝。我们还对 X. haemorrhoidalis（主模式）和 X. anisopleura（等合成模式）进行了新的形态学描述，这两个 Xylaria 物种与 X. aurantiorubroguttata 一起属于 X. polymorpha 复合体。

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.

期刊介绍： The flagship journal of the International Mycological Association. IMA Fungus is an international, peer-reviewed, open-access, full colour, fast-track journal. Papers on any aspect of mycology are considered, and published on-line with final pagination after proofs have been corrected; they are then effectively published under the International Code of Nomenclature for algae, fungi, and plants. The journal strongly supports good practice policies, and requires voucher specimens or cultures to be deposited in a public collection with an online database, DNA sequences in GenBank, alignments in TreeBASE, and validating information on new scientific names, including typifications, to be lodged in MycoBank. News, meeting reports, personalia, research news, correspondence, book news, and information on forthcoming international meetings are included in each issue
