【 摘 要 】

The genusInocybe(including subgenusMallocybe ) is a significant component of the ectomycorrhizal community in arctic and alpine habitats in terms of both diversity and distribution. Species are associated primarily with low woody shrubs ofSalix ,BetulaandDryas . There is evidence that shrubs are expanding in arctic-alpine habitats making the ectomycorrhizal fungi that support them ofhigh interest. Here we provide the first detailed report for sixMallocybetaxa with willows from the Rocky Mountain alpine zone (WY, MT, CO) including:Inocybe arthrocystis ,I. dulcamara ,I. leucoloma ,I. leucoblemaand in theI. fulvipesgroup,I. substraminipesand other taxa. Phylogenetic analysis matched Rocky Mountain specimens to arctic-alpine specimens from Scandinavia. ITS sequences of Kühner and Favre type specimens were used as references for several clades. Data suggest that these species have a broad intercontinental range in arctic-alpine habitats and a few are known from the subalpine. A key toMallocybespecies in the Rocky Mountains is provided along with type information.
