Bionectria truncata has smooth perithecia of a flattened to shallow discoid apex, clavate asci with an apical ring, and ellipsoid, smooth to spinulose ascospores. Calonectria dicephalospora is characterized by pyriform perithecia with a warted surface, clavate asci with a simple apex and long, narrow stalk, and fusoid ascospores with a cap-like appendage at each end. Haematonectria lushanensis possesses warted perithecia which are laterally collapsing when dry, cylindrical asci with a simple apex, and ellipsoid, spinulose ascospores. Neonectria dinghushanica is distinguishable by subglobose perithecia with a warted surface, clavate asci, and striate ascospores. Morphological features of these new species are described comprehensively and compared with their related fungi. Neonectria castaneicola is recorded as new to China.展开更多

文摘报道了来自黑龙江和广东的肉座菌目3个中国新记录种:异梗枝穗霉Clonostachys impariphialis、罗斯曼枝穗霉C.rossmaniae和原肉座菌Protocrea farinosa。对其宏观和微观特征进行了描述和图示,对我国材料与上述种的原始描述进行了比较,并利用ITS和28S r DNA的序列比对为准确鉴定提供了依据。此外,首次在大陆地区报道密集枝穗霉C.compactiuscula和大孔光壳Stilbocrea macrostoma并发现黄壳Ochronectria calami在广东分布。[中文摘要附注:Clonostachys属的汉名首次在综述性文章"真菌杀线虫代谢物的研究进展"中引证国外文献时提及,被译为"螺旋聚孢属"(董锦艳等2001)。随后,在作为中国新记录属发表时,文章题目将其译为"枝穗霉属"(Gao et al.2008)。考虑到后者是第一次根据我国材料对该类群进行分类学研究时提供的汉名,其译法体现了属的形态学特征,因此本文采用后一种译名作为该属的名称,并建议永久使用。]
