| 摘要: |
| 该文通过形态特征研究和基于ITS序列的分子系统学分析,对采自甘肃省连城国家级自然保护区的1份形态特殊的胶瘤菌属标本进行分类学研究。结果表明:该标本是孔生胶瘤菌(新拟)(Carcinomyces polyporina),隶属于担子菌门(Basidiomycota)、银耳纲(Tremellomycetes)、银耳目(Tremellales)、胶瘤菌科(新拟)(Carcinomycetaceae)。该物种代表了中国的1个新记录属、种,是该属在东亚地区的首次报道。孔生胶瘤菌寄生于多孔菌类真菌的子实体上,形成胶质状菌瘿,担子纵裂,担孢子可萌发后形成分生孢子。研究标本保存于中国科学院昆明植物研究所标本馆隐花植物标本室,馆藏号为HKAS 115765。 |

| Abstract: |
| This study reported a macrofungus specimen with special morphology collected from Liancheng National Nature Reserve in Gansu Province. Morphological characteristics observation and molecular phylogenetic analysis based on ITS sequences were performed. The results show that the specimen is Carcinomyces polyporina, belonging to Basidiomycota, Tremellomycetes, Tremellales, Carcinomycetaceae, which represents a newly recorded genus and species in China, and is the first report of this genus in East Asia. Carcinomyces polyporina is characterized by parasitism on polypores fruitbody, forming gelatinous mycocecidium, basidia with longitudinally septate, and conidia commonly gemmated from basidiospores germination. The specimen is deposited in the Herbarium of Cryptoflora, Kunming Institute of Botany, Chinese Academy of Sciences(HKAS 115765). |
