Abstract
The new species Bojamyces transfuga is described. It was found growing in the hindgut of mayfly nymphs and in their shed abdominal exoskeleton lumen. Bojamyces transfuga shows single appendaged trichospores and zygospores of type I, unlike Bojamyces repens, where appendages and zygospores are unknown. The generic description of Bojamyces is emended to accommodate this new taxon. Bojamyces repens, known only from the United States, has been found for the first time in the Iberian Peninsula on mayfly molts. We also note the presence of Legeriomyces rarus in Europe, on the Iberian Peninsula and Balearic Islands. Previously it was known only in Western Australia.
