羊肚菌烂柄病发生对土壤真菌群落结构的影响

为了解羊肚菌(Morel)烂柄病的发生对土壤真菌群落结构的影响,采用Illumina MiSeq高通量测序技术,对健康羊肚菌根际土、烂柄病发病子实体根际土及相同环境下未栽培羊肚菌土壤的真菌群落结构进行研究。结果表明,测序样品共获得344 163条序列,归为7个真菌门。各样品真菌多样性分析结果表明,未栽培土壤真菌群落多样性较高,栽培羊肚菌根际土壤真菌多样性显著降低,烂柄病发生后土壤真菌多样性增加。群落结构分析表明,烂柄病根际优势真菌类群为拟青霉属(Paecilomyces)、木霉属(Trichoderma)、葡萄穗霉属(Stachybotrys)、枝顶孢属(Acremonium)、Paratritirachium、Zopfiella、被孢霉属(Mortierella)和柄孢壳属(Podospora)。烂柄病的发生改变了土壤真菌群落结构,促进了根际真菌的繁殖。为了解羊肚菌烂柄病的发生、传播机理及防治提供了参考。

The mushroom family Psathyrellaceae: evidence for large-scale polyphyly of the genus Psathyrella

Psathyrella is the archetypal little brown mushroom genus with few easily discernable characters causing it to be considered a "clean-up" genus for other small brown-spored saprotrophic species found worldwide. While molecular studies have demonstrated that mushroom genera based on homoplastic morphological characters are artificial, the degree of phylogenetic heterogeneity contained within Psathyrella and Psathyrellaceae has never been appropriately addressed. For this study, 132 ribosomal sequences from approximately one-tenth of the known Psathyrella species worldwide, including representatives of most subgeneric subdivisions, and three closely related coprinoid genera (Parasola, Coprinopsis, Coprinellus) were evaluated using multiple phylogenetic methods, including likelihood, with Agaricaceae as the outgroup. Our results indicated that Psathyrella was polyphyletic. Conservatively, the genus can be separated into 11 clades of which five can be raised to generic status. Most species of Psathyrella, including its type species P. gracilis, formed a large clade with Coprinellus, which appeared to be derived from within Psathyrella. Generic limits of Parasola, Lacrymaria, and Coprinopsis should be reevaluated. Several taxa previously synonymized based on morphological features were phylogenetically distinct. Morphological features traditionally used to subdivide Psathyrella appeared to be mostly convergent (homoplasious) when traced upon the resulting phylogenies, although several had high RI values. These results were interpreted in light of the two major taxonomic treatments of Psathyrella and revealed substantial inconsistencies between the molecular- and morphology-derived inferences of relationships.

中国鹅膏菌属(担子菌)的物种多样性

鹅膏菌属（Ａｍａｎｉｔａ）是一个近世界性广布的大属,全球已被描述而又被承认的有近５００种。在文献中,我国此属已记载约２００种。然而,许多种都是原初描述于欧洲或北美的种类。近来的研究表明,东亚的鹅膏菌独特且有其自身的分布范围。东亚的有些种虽与产于欧洲或北美的某些种相似,但仔细的野外观察,详尽的形态解剖学和分子进化生物学研究结果表明,东亚的鹅膏菌是独立的分类群。在欧洲,人们有采集著名食菌恺撒鹅膏菌的习     

中国暗金钱菌属分类研究概况
