Importance and distribution
Species of Phaeophleospora are associated with leaf spot. There are 30 Phaeophleospora epithets in Index Fungorum (2022), but some have been transferred to other genera such as Septoria, Kirramyces, Teratosphaeria, Brunswickiella and Readeriella. Phaeophleospora comprises 19 species known on six plant families, Arecaceae, Myrtaceae, Plantaginaceae, Polypodiaceae, Proteaceae and Sapotaceae. Phaeophleospora is reported mainly from Africa (Réunion), Asia (Thailand), Europe (Switzerland), New Zealand and South America (Brazil).
Biochemical importance of the genus, chemical diversity or applications
Phaeophleospora vochysiae produces bioactive secondary metabolites such as cercoscosporin, isocercosporin, and 3-(sec-butyl)-6-ethyl-4,5-dihydroxy-2-methoxy-6-methylcyclohex-2-enone. The latter shows antimicrobial activity and low cytotoxicity (Savi et al. 2018). Phaeophleospora may produce a wide array of chemicals. More studies are needed.
