Abstract

Russula rubrosquamosa (Russulaceae, Russlales) is described as a novel species from Yunnan Province, southwestern China. It is morphologically recognised by a small basidiocarp with orange-yellow to orange-red scales on the pileus and stipe, white lamellae, orange-red to bright red basal mycelia, subglobose to broadly ellipsoid basidiospores with dense warts and short or long ridges. Phylogenetically analyses of DNA sequences from part of the 28S gene combined with the nuclear rDNA internal transcribed spacer (ITS) region also confirm that R. rubrosquamosa forms an independent lineage within Russula subgenus Heterophyllidia section Ingratae. A comprehensive description, color photographs of fresh basidiomata, line-drawings of microstructures and comparisons with morphologically similar species are provided in this paper.

Russula rubrosquamosa (Russulaceae, Russulales),中国西南部的一个新种
Russula rubrosquamosa(Russulaceae,Russlales)是中国西南部云南省的一个新物种。从形态上看,它的基生果实较小,绒毛和柄上有橙黄色至橙红色的鳞片,有白色的薄片,基部菌丝橙红色至鲜红色,基部孢子近球形至宽椭圆形,有密集的疣和短或长的脊。通过对 28S 基因的部分 DNA 序列与核 rDNA 内部转录间隔区(ITS)的系统发育分析,也证实了 R. rubrosquamosa 在 Russula 亚属 Heterophyllidia 部分 Ingratae 中形成了一个独立的品系。本文提供了全面的描述、新鲜基生体的彩色照片、微观结构的线描图以及与形态上相似物种的比较。

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.
