The name Colletotrichum gloeosporioides was first proposed in Penzig (1882), based on Vermicularia gloeosporioides, the type specimen of which was collected from Citrusin Italy. Much of the early literature used this name to refer to fungi associated with various diseases of Citrus, with other species established for morphologically similar fungi from other hosts. However, several early papers discussed the morphological similarity between many of the Colletotrichumspp. that had been described on the basis of host preference, and used inoculation tests to question whether or not the species were distinct. Some of these papers investigated in culture the link between the various Colletotrichumspecies and their sexual Glomerellastate (e.g.Shear & Wood 1907, Ocfemia & Agati 1925). Authors such as Shear & Wood (1907, 1913) and Small (1926) concluded that many of the species described on the basis of host preference were in fact the same, rejecting apparent differences in host preference as a basis for taxonomic segregation. Small (1926) concluded that the names Glomerella cingulataand Colletotrichum gloeosporioidesshould be used for the sexual and asexual morphs, respectively, of the many Colletotrichumspp. they regarded as conspecific. Colletotrichum gloeosporioideswas stated to be the earliest name with a proven link to what they regarded as a biologically diverse G. cingulata. The studies of von Arx & Müller (1954) and von Arx (1957, 1970) taxonomically formalised this concept.
