【摘要】 报道密格孢属及相似属真菌13种,包括1新种和6个中国新记录种。新种隔孔密格孢的主要特征是分生孢子梗非绝顶式,具有连续的末端产孢增生,增生烧瓶状,分生孢子砖格状,通常具3-4个平行的横膈膜,多个纵、斜隔膜,具有明显的隔膜孔。新记录种为黑顶密格孢、畸形密格孢、马拉密格孢、含笑密格孢、戴氏假密格孢和黑褐梗裂密格孢。对这些分类单位提供了描述和图,并且比较了它们的形态异同性。更多还原

【Abstract】 Taxonomic studies on Acrodictys and related genera in China have yielded 13 taxa including a new species,Acrodictys septi-porosa sp.nov.,characterized by indeterminate conidiophore with successive terminal lageniform proliferations and muriform conidia usually with 3-4 parallel transverse septa,several perpendicular longitudinal or oblique septa,and the presence of conspicuous septal pores.Acrodictys atroapicula,A.irregularis,A.malabarica,A. micheliae,Pseudoacrodictys deightonii,and Rhexoacrodictys fuliginosa are newly recorded for China.Descriptions and illustrations of all taxa are provided,and similarities or differences with morphologically close taxa are discussed.更多还原
