摘要

根据在日本西部鸟取县常绿栎(Quercus myrsinifolia)为主的栎林中发现的样品,描述和说明了口蘑科的一个新物种,即T. olivaceonigrum。它的特征是圆锥伞形,深绿色橄榄状的毛具黑色的固有原纤维;一种带白色丝状纤维的柄,通常淡黄和具一狭窄的近尖的基部;近球形到宽椭圆形孢子;在初冬结实。针对核糖体RNA基因内部转录间隔区进行的系统发育分析表明,T. olivaceonigrum与T. portentosum形成了一个良好的分支姐妹。讨论了其他形态和系统发育密切相关的口蘑科物种。

Tricholoma olivaceonigrum, a new species of the section Tricholoma (Agaricales) from Japan.

A novel species of Tricholoma section Tricholoma, namely, T. olivaceonigrum, is described and illustrated based on samples found in an oak woods dominated by Quercus myrsinifolia, an evergreen oak, in Tottori Prefecture, western Japan. It is characterized by a conic-umbonate, dark-greenish olivaceous pileus with blackish innate fibrils; a whitish silky-fibrillose stipe, often faintly tinted pale yellow and with a narrowed subpointed base; subglobose to broadly elliptic spores; and fruiting in early winter. Phylogenetic analysis targeting the internal transcribed spacer region of the ribosomal RNA gene revealed that T. olivaceonigrum forms a well-supported clade sister to T. portentosum. Other morphologically and phylogenetically closely related species of the section Tricholoma are discussed.

期刊介绍: Mycoscience is the official English-language journal of the Mycological Society of Japan and is issued bimonthly. Mycoscience publishes original research articles and reviews on various topics related to fungi including yeasts and other organisms that have traditionally been studied by mycologists. The research areas covered by Mycoscience extend from such purely scientific fields as systematics, evolution, phylogeny, morphology, ecology, physiology, biochemistry, genetics, and molecular biology, to agricultural, medical, and industrial applications. New and improved applications of well-established mycological techniques and methods are also covered.
