Abstract

Three cleistothecial marine Ascomycotina collected on driftwood along the Danish coasts are compared. The three species are described as new and each accommodated in its own new genus: Biflua physasca, Marisolaris ansata, and Dryosphaera navigans. Dryosphaera navigans is a new name for what earlier was understood as Crinigera maritima Schmidt, a cleistothecial fungus with treelike appendages covering the surface of the peridium and ascospores with slime threads spirally uncoiling from the spore wall. All three species have cleistothecia with sterile appendages, occur on driftwood associated with sand, are loosely attached to the substratum at maturity, and have appendaged ascospores. The morphological characters of the three species are compared and all are considered to have affinities to the bitunicate ascomycetes. Tentatively D. navigans is assigned to the Coronophorales, but no order or family was found to accommodate the remaining new species. An amended diagnosis is provided for Crinigera maritima Schmidt, and it is concluded that material does not show whether the fungus is an ascomycete or a fungus imperfectus.
