本文报道了Orbilia属一新种：Orbilia，O. yuanensis（Orbiliales，Orbiliomycetes），采自中国云南和台湾。该真菌与以前已知的Orbiliaspecies不同，因为它具有杆状的子囊孢子和泪状的孢子体。从子囊孢子分离物获得的无性型的特征在于产生长的、弯曲的大分生孢子和小得多的、部分螺旋状的小分生孢子。形态学上，这种无性型符合多系属Anguillospora。通过对两个分离物的ITS区序列分析，发现O.在Orbilia lurestructions ubella聚集体中，近缘种间的距离较远，而远缘种间的距离较远。到目前为止，有两个关于Orbiliaspecies和他们的Anguillosporaanamorph之间的联系的报告。O.本文是第三篇报道。在本文中，无论是有性和无性型的说明和描述。
A new species of the genusOrbilia,O. yuanensis(Orbiliales, Orbiliomycetes), was collected from Yunnan Province (China) and Taiwan. The fungus differs from previously knownOrbiliaspecies in that it has rod-shaped ascospores with a tear-shaped spore body. An anamorph that was obtained from ascospore isolates is characterized as producing long, curved macroconidia and much smaller, partly helicoid microconidia. Morphologically, this anamorph fits the polyphyletic genusAnguillospora. Based on a sequence analysis of the internal transcribed spacer region (ITS) gained from two isolates,O. yuanensisnested near species of theOrbilia luteorubellaaggregate, although at a rather high distance. To date, there have been two reports regarding a connection betweenOrbiliaspecies and theirAnguillosporaanamorph. The connection betweenO. yuanensisand itsAnguillosporaanamorph discussed here is the third published report. In this paper, both teleomorph and anamorph are illustrated and described.
