篮状菌属分类概述及三个中国新记录种

篮状菌属真菌在空气、土壤中分布广泛,有些种类是重要的工业酶及色素生产菌,有些则可以引起食品的污染变质,还有些种是引起浅层或散播性感染的条件致病菌,如马尔尼菲篮状菌。篮状菌属在传统分类学上是一个有性型属,随着多相分类以及“一种真菌一个名称”概念的广泛普及,该属的概念已经发生了较大的变化,目前全世界已报道177个种。本文基于国内外最新研究结果,对篮状菌属的分类现状、种的范围和形态学区分等进行了概述,同时基于多基因系统发育树以及形态学观察描述了3个中国新记录种Talaromyces amazonensis N. Yilmaz, López-Quint., Vasco-Pal.、T. chloroloma Visagie & K. Jacobs和T. minnesotensis Guevara-Suarez, Cano & Dania García,并详细比较了它们与模式菌株的形态学差别。

Current taxonomy and three new Chinese records of Talaromyces

Species in the genus Talaromyces are widely distributed in air and soil, some species are important producers of industrial enzymes and pigment, and certain species, e.g. Talaromyces marneffei, were reported to cause superficial or disseminated infections to humanity. Talaromyces traditionally is a teleomorphic genus, but according to polyphasic taxonomy and “one fungus, one name” rules, nowaday concept of this genus has changed greatly. This genus now contains about 177 species. In this paper, the taxonomic status, species concepts and morphological differences of Talaromyces species are reviewed. In addition, three new Chinese records, Talaromyces amazonensis, T. chloroloma and T. minnesotensis are described based on multigene phylogenetic analysis and morphological observations, and their differences with ex-type cultures were compared in detail.
