New species and notes of Colletotrichum on daylilies (Hemerocallis spp.)

Abstract

Nine Colletotrichum strains were isolated from diseased and dead stalks of Hemerocallis species (daylilies) from Guizhou, Guangxi, and Liaoning provinces in China. Morphological characteristics and multilocus phylogenetic analysis of ACT, CHS I, GPDH, ITS, and TUB 2 indicate that these strains represent four taxa. Colletotrichum hemerocallidis is a new species that is described, illustrated, and compared with similar species. Colletotrichum gloeosporioides, C. liriopes, and C. spaethianum are also recorded on Hemerocallis species.
