Abstract

Erysiphe actinidiicola on Actinidia polygama is described based on morphological and molecular data. Erysiphe actinidiicola is distinguished from E. actinidiae var. actinidiae by having irregularly to dichotomously branched chasmothecial appendages, larger chasmothecia sizes and numbers of asci per chasmothecium. Molecular analyses indicated that this species forms a clade separated from E. actinidiae var. actinidiae. An epitype is proposed for E. actinidiae var. actinidiae with ex-epitype sequences. A powdery mildew found on Limonium tetragonum is tentatively described as Erysiphe sp. This species is distinguished from E. limonii, a powdery mildew on Limonium spp., based on the DNA sequence differences in the 28S rDNA and internal transcribed spacer region as well as the morphological differences in the length of the conidiophores. This is the first record of powdery mildew on L. tetragonum in the world.

日本白粉病(丹毒科)二新记录:丹毒(Erysiphe actinidiicola sp. 11 .)和丹毒(Erysiphe sp. on Limonium tetragonum)。

根据形态和分子资料描述了猕猴桃上的猕猴桃。actitindiicola与actitindiae变种actitindiae的区别在于具有不规则至二分叉的裂口附属物，较大的裂口大小和每个裂口的囊数。分子分析表明，该物种是由猕猴桃变种猕猴桃分离出来的一个分支。提出了具有前表型序列的actinidiae变种actinidiae表型。在Limonium tetragonum上发现的一种白粉病暂定为Erysiphe sp.，根据其28S rDNA和内部转录间隔区的DNA序列差异以及分生孢子长度的形态差异，将其与limonii E. limonii白粉病区分。这是世界上首次记录到白粉病。

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.
