New and interesting records of South African fungi. XV. Two new Laboulbeniales records from South Africa

The Laboulbeniales are predominantly parasites of true insects (Hexapoda), infesting mostly Coleoptera. Two members of the Laboulbeniales are reported from South Africa for the first time; Polyandromyces coptosomalis Thaxter and Laboulbenia monoleptae Balazuc. Both fungi are illustrated and their distribution, morphology, host specificity and nutrition are discussed.
