Plejobolus arenarius.
Abstract A description is provided for Plejobolus arenarius, found on dead leaves of Ammophila, a grass of coastal sand ecosystems. Nothing is known about when it colonizes the substratum, but it is saprobic by the time ascomata are produced. Some information on its habitats, dispersal and transmission and conservation status is given, along with details of its geographical distribution (Europe (Belgium, Sweden, UK)).
