Three fungicolous hyphomycetes are described and illustrated. Anastomyces gen. nov., with the type species A. microsporus sp. nov., is described on ascomata of Apiospora sp. on dead culms of a grass from China. It differs from comparable genera by its fungicolous habitat, sporodochial conidiomata and polylocal conidiogenous cells mostly with 2 loci. Each locus produces one conidium but two conidia formed from the same conidiogenous cells join together to form H-shaped conidia in the earliest stages of their development. Idriella rhododendri sp. nov. grows over other microfungi and is described from leaf litter of Rhododendron ponticum from England. Infundibura adhaerens was found to be commonly associated with ascomata and conidiomata on dead leaves of R. ponticum in England.
