英文摘要: The rare sequestrate fungus Amogaster viridiglebus is known from only one collection in California where it was discovered among Populus roots. Based on sporocarp coloration and spore morphology, this sequestrate taxon was putatively considered to be an ectomycorrhizal member of the Boletales. However, no molecular data were previously available to definitively determine the closest relatives of this fungus. Here we revisit the morphology of Amogaster viridiglebus and present a phylogenetic analysis based on ITS and 28S ribosomal DNA. Our phylogeny indicates that Amogaster viridiglebus is nested in the genus Lepiota, suggesting that this rare species has a saprobic trophic mode and does not form ectomycorrhizae with plants. A new combination, L. viridigleba, is made based on these phylogenetic results.
