Abstract

The genus Pholiota (Strophariaceae, Basidiomycota) is made up of wood-rotting saprotrophic mushrooms characterized by a yellow or brown pileus with scales and/or slimy, and by a brownish smooth spore with a germ pore. However, these features are not enough to distinguish its species, or separate the genus Pholiota from other brown-spored wood-rotting genera such as Hypholoma and Stropharia. Although internal transcribed spacer (ITS) sequence-based identification has improved identification accuracy for species of Pholiota, most Pholiota species in Korea are reported based on morphological features. To evaluate the taxonomy of Pholiota species, we investigated 62 specimens collected from 1999 to 2019 in Korea using ITS sequence analysis and morphological observation. Twelve of the 16 recorded Pholiota species in Korea were identified. While eight species were clearly separated, the ITS analysis did not distinguish three in the Pholiota adiposa complex. Therefore, further investigation is required to distinguish these three species. ITS sequences deposited in GenBank confirm that P. highlandensis exists in Korea. The presence of the other four Pholiota species could not be confirmed through specimens or sequence information in GenBank. A taxonomic key and the ITS sequence data for Korean Pholiota species are included and can be good baselines for further research on Pholiota taxonomy and diversity.

 抽象的

伞菌属（球盖菇科、担子菌门）由腐木腐生蘑菇组成，其特征是具有鳞片和/或粘液的黄色或棕色菌盖，以及具有芽孔的棕色光滑孢子。然而，这些特征不足以区分其物种，或将黄伞属与其他棕色孢子腐木属（如丝菌属和大球盖菇属）区分开来。虽然基于内部转录间隔区（ITS）序列的鉴定提高了黄伞属物种的鉴定准确性，但韩国大多数黄伞属物种的报道都是基于形态特征。为了评估黄伞属的分类学，我们利用 ITS 序列分析和形态观察对 1999 年至 2019 年在韩国收集的 62 个标本进行了调查。韩国记录的 16 种黄伞物种中，有 12 种已被鉴定。虽然清楚地区分了八个物种，但 ITS 分析并未区分黄伞复合体中的三个物种。因此，需要进一步研究来区分这三个物种。 GenBank 中存放的 ITS 序列证实韩国存在P. highlandensis 。无法通过标本或 GenBank 中的序列信息确认其他四种黄伞属物种的存在。其中包括韩国黄伞物种的分类学索引和 ITS 序列数据，可以为进一步研究黄伞分类和多样性提供良好的基线。
