New zealand fungi 17. Pleomorphism in euantennariaceae and metacapnodiaceae, two new families of sooty moulds

Abstract

Investigations of sooty moulds from New Zealand reveal two main groups of species, both of which display distinctive and regular pleomorphism. In one group the hyphae are more or less cylindrical with thc cells generally longer than broad: ascostromata have a Dothidea type centrum and the phialidic and phragmoconidial states are distinctive and diagnostic. This group is included in a new family Euantennariaceae Hughes and Corlett (Dothideales sensu lato). In the second group the hyphae are more or less tapering with the cells generally broader than long: ascostromata have a Pleospora type centrum and the phialidic state is distinctive as are the sympodial, poroconidial, and arthroconidial states if produced. This second group is included in a new family Metacapnodiaceae Hughes and Corlett (Pleosporales). The type species of the type genera of the new families are illustrated and redescribed. © 1972 Taylor & Francis Group, LLC.
