“…Owing to its sac-like appearance, the sporogenous cell was originally interpreted as an ascus and therefore M. osmundae was first described in the Ascomycota as Taphrina osmundae Nishida (Nishida, 1911). More than 80 yr later, detailed morphological and molecular studies showed that M. osmundae holds a rather isolated position within the Basidiomycota, with the simple-septate species now placed together within Pucciniomycotina Sugiyama, 1998;Sjamsuridzal et al, 2002;Aime et al, 2006).…”

SummaryMixia osmundae (Basidiomycota, Pucciniomycotina) represents a monotypic class containing an unusual fern pathogen with incompletely understood biology. We sequenced and analyzed the genome of M. osmundae, focusing on genes that may provide some insight into its mode of pathogenicity and reproductive biology.Mixia osmundae has the smallest plant pathogenic basidiomycete genome sequenced to date, at 13.6 Mb, with very few repeats, high gene density, and relatively few significant gene family gains.The genome shows that the yeast state of M. osmundae is haploid and the lack of segregation of mating genes suggests that the spores produced on Osmunda spp. fronds are probably asexual. However, our finding of a complete complement of mating and meiosis genes suggests the capacity to undergo sexual reproduction. Analyses of carbohydrate active enzymes suggest that this fungus is a biotroph with the ability to break down several plant cell wall components.Analyses of publicly available sequence data show that other Mixia members may exist on other plant hosts and with a broader distribution than previously known.
