Abstract

Caladium ( Caladium × hortulanum ) is an ornamental plant popular for its variable and colorful foliage. In 2020, plants showing leaf spots and blight, typical of anthracnose, were found in a field trial at the University of Florida's Gulf Coast Research and Education Center in Wimauma, Florida, U.S.A. Leaf samples consistently yielded a Colletotrichum- like species with curved conidia and abundant setae production in the acervuli. The internal transcribed spacer (ITS), partial sequences of the glyceraldehyde-3-phosphate dehydrogenase gene ( gapdh ), actin gene ( act ), chitin synthase 1 gene ( chs-1 ), beta-tubulin gene ( tub2 ), and histone3 gene ( his3 ) were amplified and sequenced. BLASTN searches in the NCBI GenBank database revealed similarities to species of the Colletotrichum truncatum species complex. Phylogenetic analyses using multilocus sequence data supports a distinct species within this complex, with the closest related species being C. curcumae . Based on morphological and phylogenetic analyses, a new species of Colletotrichum , named C. caladii , is reported. Pathogenicity assays and subsequent isolation confirmed that this species was the causal agent of the disease., Competing Interests: The author(s) declare no conflict of interest.
