Marine ascomycetes from algae and animal hosts

Although the number of algicolous fungi is small, they are of particular interest because of their parasitic or symbiotic properties. Only 79 species of filamentous fungi - out of a total of 465 marine species - are associated with marine algae, and 18 with animals; many of them have not been illustrated in detail. The present paper provides illustrations and full descriptions of 8 marine ascomycetes, 6 of them from algae and 2 from animal hosts. The algicolous species belong to the genera Didymella, Haloguignardia, Spathulospora and Turgidosculum; those from animals are members of Abyssomyces and Laboulbenia. The illustrations are line drawings made with the aid of a camera lucida, and are almost all based on type material.
