摘要

毛菌是一组生活在未成熟水生昆虫和其他节肢动物内脏中的真菌和原生生物。这种关系的本质尚不清楚，但它大多被描述为专性共生，微生物利用一个独特的微栖息地。在不列颠哥伦比亚省东南部落基山脉的一部分哥伦比亚山脉卡斯尔加附近的水生栖息地，从淡水昆虫中收集了毛菌。采集地点位于海拔435至935米之间，于2006年7月采集。共记录到32种，其中新种4种，分别是filispora Harpella、columbiensis orphiella、Smitium nodiradicatum、Smitium basiangustatum。这是加拿大西部的第一个记录，另外两个，Austrosmittium patagonicum和Glotzia distorta是新的大陆记录。这些发现与来自爱达荷州博伊西山脉附近的落基山脉西部边缘和科罗拉多州南落基山脉的报告进行了比较。

Trichomycetes from the Columbia Mountains, British Columbia, Canada

Trichomycetes are a group of fungi and protists living in the guts of immature aquatic insects and other arthropods. The nature of this relationship is poorly understood but it is mostly described as obligately commensalistic, with the microbes exploiting a unique microhabitat. Collections of trichomycetes were made from freshwater insects in aquatic habitats near Castlegar in the Columbia Mountains, part of the Rocky Mountain Range in southeastern British Columbia. The collection sites were at altitudes ranging from 435 to 935 m and were made in July 2006. A total of 32 species were recorded including four new species, Harpella filispora sp. nov., Orphella columbiensis sp. nov., Smittium nodiradicatum sp. nov., and Smitium basiangustatum sp. nov. described here. These are the first records from Western Canada and two, Austrosmittium patagonicum and Glotzia distorta are new continental records. These findings are compared to reports from the western edge of the Rocky Mountain range near the Boise Mountains in Idaho and the Southern Rockies in Colorado.
