Importance and distribution

Species of Rhabdospora are associated with leaf spot. There are 122 Rhabdospora epithets in Index Fungorum (2022), but several species have been transferred to other genera such as Ascochyta, Coleoseptoria, Cylindrosporium, Diplodina, Foveostroma, Groveolopsis, Harpostroma, Kellermania, Mazzantia, Mycosphaerella, Neofabraea, Nodulosphaeria, Peroneutypa, Phacidiella, Phlyctema, Phomopsis, Pseudodiplodia, Scolecosporiella, Selenophoma, Septocyta, Septoria, Septoriella, Stagonospora, Stamnaria, Titaeospora and Valsa. Rhabdospora comprises 30 species known on wide range of host such as Annona squamosa (Annonaceae), Banisteria laurifolia (Malpighiaceae), Chrysanthemum maximum (Asteraceae), Cinnamomum camphora (Lauraceae), Convolvulus arvensis (Convolvulaceae), Cycas revoluta (Cycadaceae), Ephedra intermedia (Ephedraceae), Erigeron annuus (Asteraceae), Euphorbia pulcherrima (Euphorbiaceae), Fraxinus pennsylvanica var. subintegerrima (Oleaceae), Heteropterys laurifolia (Malpighiaceae), Hevea brasiliensis (Euphorbiaceae), Juncus balticus (Juncaceae), Nephelium lappaceum (Sapindaceae), Vernonia menthaefolia (Asteraceae) and Xerophyllum tenax (Melanthiaceae). Rhabdospora seems to be host specific as each species occurs on a particular host plant or plant genus. Rhabdospora has been reported from several countries including Asia (India, Malaysia, Thailand), North America (Caribbean (Cuba), Canada, the United States), South Africa and South America (Venezuela) Rhabdospora comprise many species but with taxonomic pitfalls as several species lack molecular data and require revision. An attempt to recollect and sequence the type species is needed to understand the diversity and taxonomy of Rhabdospora.
