Leucostoma
Leucostoma is a genus of ascomycete fungi in the family Cytosporaceae (order Diaporthales). Species in this genus are plant pathogens that cause canker diseases, primarily affecting woody hosts. The genus produces both sexual (perithecia) and asexual (pycnidia) fruiting bodies, with the asexual stage formerly classified under the name Leucocytospora. Leucostoma species are distributed across temperate regions of North America, Europe, and Asia.
