Abstract

In this work, we characterize naturally occurring mycorrhizae formed by Amanita viscidolutea on Guapira opposita in the Atlantic Forest in Brazil. We sequenced the rDNA ITS region from the mycorrhizae and basidiomata to identify both symbionts. Amanita viscidolutea mycorrhizae were up to 43 mm long, mostly simple, and unbranched to irregularly pinnate. The fungal mantle surface was velvety to slightly cottony and white to yellowish with silver patches. Hyphal strands were infrequently present. Although the fungal mantle consisted of clampless hyphae, emanating hyphae and hyphal strands had sparsely distributed clamp connections. A unique character of the mycorrhizae was the absence of a Hartig net.

巴西大西洋森林中一种原生菌根毒伞属植物的形态解剖和分子特征。
在这项工作中,我们在巴西大西洋森林的瓜皮拉上表征了天然发生的菌根。我们对菌根和担子菌的rDNA ITS区域进行了测序,以鉴定这两种共生体。毒金刚伞菌根长可达43毫米,多为单根,不分枝至不规则羽状。真菌的地幔表面丝绒状至微棉状,白色至淡黄色,有银色斑块。菌丝很少出现。虽然真菌的衣壳由无夹丝菌丝组成,但萌发菌丝和菌丝链具有稀疏分布的夹丝连接。菌根的一个独特特征是没有Hartig网。

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.
