Colletotrichum siamense, C. theobromicola and C. queenslandicum from several plant species and the identification of C. asianum in the Northern Territory, Australia

Four species, Colletotrichum asianum, C. queenslandicum, C. siamense and C. theobromicola, were isolated and identified from several plants species in the Northern Territory, Australia. Some of these fungal associations represent first reports, namely, C. queenslandicum on Passiflora edulis; C. siamense on Artocarpus heterophyllus, Eriobotrya japonica, Ficus carica, Mentha sp., Piper nigrum, Rosmarinus officinalis and Theobroma cacao; and C. theobromicola on Coffea canephora and C. arabica. Colletotrichum asianum was isolated from mango for the first time in the NT. These collections help provide evidence for the absence of Colletotrichum spp. of biosecurity importance in the Northern Territory.
