Abstract: Bryoscyphus hyalotectus (Helotiales, Ascomycota) is presented as a new species based on a single collection from Canada. It infects the moss Polytrichum juniperinum. Apothecia occuby a special microniche on the host plant. They develop between the leaf lamellae where the inflexed leaf margins meet. The parasite is distinguished by intracellular haustoria that arise directly from superficial hyphae without intervention of appressoria.
