Anthracnose of Centipedegrass Turf

Abstract

Taxonomy Eukaryota; Fungi; Dikarya; Ascomycota; Pezizomycotina; Sordariomycetes; Hypocreomycetidae; Glomerellales; Glomerellaceae; Mitosporic Glomerellaceae; Colletotrichum; Colletotrichum eremochloae J.A. Crouch & Tomaso-Peterson. C. eremochloae was recently described based on DNA sequence data of modern cultures and archival fungarium specimens. The identification of C. eremochloae sp. nov., a pathogen of centipedegrass, was made based on phylogenetic evidence from four sequence markers, Apn2, Apn2/Mat1, Sod2, and ITS (1). C. eremochloae is closely related to C. sublineola, the pathogen of sorghum [Sorghum halapense (L.) Pers] and johnsongrass (S. vulgaris Pers.), but genealogical concordance supported their distinction as phylogenetic species (1). Currently, centipedegrass is the only host from which C. eremochloae has been isolated and confirmed as a pathogen. No teleomorph of C. eremochloae has been identified.
