| 中文摘要: |
| 在对我国腐生粪壳纲真菌的研究中，发现了1个新记录属和2个中国新记录种。3个种均形成闭囊果，果上生独特的子囊果毛，子囊孢子单细胞、暗色。异果刺囊壳Ascotricha distans的主要特征为产生具膝曲状合轴分枝的子囊果毛，子囊孢子具芽缝，无性阶段为Dicyma型，归属炭角菌目炭角菌科。旋毛米氏壳Emilmuelleria spirotricha和粪闭毛壳Chaetomidium fimeti产生具芽孔、表面光滑的子囊孢子，归属粪壳目毛壳科。其中米氏壳属作为单种属，是我国的一个新记录属。文中对各个种进行了形态描述和讨论。研究菌株保存于中国科学院微生物研究所中国普通微生物菌种保藏管理中心。 |
| 英文摘要: |
| Three cleistothecial fungi including two new to China were isolated in our survey of heterotrophic Sordariomycetes, each possessing distinct ascomatal hairs and single-celled dark ascospores. One of the isolates is characterized by ascomatal hairs with geniculate and sympodial branches, ascospores with germ slits and Dicyma-like asexual stage, and is assigned to Ascotricha distans in the Xylariaceae under Xylariales. Two others share smooth ascospores with germ pores, and are identified as Chaetomidium fimeti and Emilmuelleria spirotricha respectively, both in the Chaetomiaceae under Sordariales. Among them, Emilmuelleria is monotypic and recognized here as a newly recorded genus in China. Descriptions, illustrations and discussion of each species were given. The studied strains were preserved at China General Microbiological Culture Collection Centre (CGMCC) in the Institute of Microbiology, CAS. |
