摘要

在云南对藓类进行调查时,在活橡树的腐烂木材和树皮上发现了三种厌食性的藓属。这些种的特征是黑色的闭膜孢子,有6-8个齿状裂片,可以是有柄的,也可以是无柄的,有灰白色到橙色的膜层,一个发育良好的覆盖层和基间质,由碳化到透明的角细胞或透明的菌丝组成,有一个由透明的角细胞组成的膜层,棒状的,J型子囊,有椭圆形或圆形的先端,长针状和椭圆形的子囊孢子,有多个间隔。在LSU-ITS-mtSSU数据集的形态特征和系统发育分析的支持下,将长孢子三角虫、刺状三角虫和大叶三角虫描述为三角虫属的新种。详细的描述,插图和多基因分析充分支持每个物种。

Updating the diversity: three novel species of Triblidium (Triblidiaceae, Rhytismatales) in west Yunnan, China.

During a survey of discomycetes in Yunnan, China, three saprobic species of Triblidium were discovered on decayed wood and the bark of living oak trees. These species are characterised by black cleistohymenial apothecia with 6-8 teeth-like lobes, which can be either stipitate or sessile, with greyish-white to orange hymenium, a well-developed covering and basal stroma, consisting of carbonised to hyaline angular cells or hyaline hyphae, with a subhymenium composed of hyaline angular cells, clavate, J- asci, with an elliptical or rounded apex and long acicular and ellipsoidal ascospores with multiple septa. Triblidium longisporum, T. stipitatum and T. daliense are described as new species within Triblidium, supported by both morphological features and phylogenetic analyses of the LSU-ITS-mtSSU dataset. Detailed descriptions, illustrations and multi-gene analyses fully support each species.
