Althoughcommon from single ascospores, the bright, conidial cultural typeis rarely formed by isolates from nature (unpubl. data). Similardimorphic cultural types have been observed also from singleascospore isolates from a member of the C. boninense complex,C. constrictum (unpubl. data, P.R. Johnston).Other specimens examined: Brazil, on leaves of Miconia sp., coll. R. BarretoRWB1054, 2009 (ICMP 18728).

Shear, Apr. 1922 (authentic culture ofG. rufomaculans var. vaccinii – CBS 124.22 = ICMP 19122).Colletotrichum manihotis Henn., Hedwigia 43: 94. 1904.Notes: Anthracnose is an important disease of cassava (e.g.Chevaugeon 1956, Makambila 1994, Fokunang et al. 2000,Owolade et al. 2008), variously referred to Colletotrichum manihotis,Gloeosporium manihotis Henn., Glomerella manihotis (Sacc.)Petr., Glomerella cingulata “f. sp. manihotis”, or C. gloeosporioides“f. sp. manihotis”. The original descriptions of both C. manihotisand Gloeosporium manihotis are of species with short, broadconidia (8–15 × 4–6 µm), and Chevaugeon (1956) regarded all ofthese cassava-associated fungi as con-specific. However, basedon Fokunang et al. (2000), a morphologically highly diverse set ofColletotrichum isolates are associated with diseased plants. Thereare three GenBank accessions of Colletotrichum from cassava,all from China, and although only ITS sequences are available forthese isolates, they appear to represent a single, distinct specieswithin the C. gloeosporioides complex. How these Chinese isolatesrelate to cassava-associated isolates from other parts of the worldis not known.* Colletotrichum musae (Berk. & M.A. Curtis) Arx, Verh.Kon. Ned. Akad. Wetensch., Afd. Natuurk., Sect. 2 51(3):107. 1957. Fig. 28.Basionym: Myxosporium musae Berk. & M.A. Curtis, Grevillea 3:13. 1874.Su et al. (2011) provide a description.Geographic distribution and host range: Found in association withfruit lesions of Musa spp. in many regions.Genetic identification: ITS sequences separate C. musae from allother species.Notes: Colletotrichum musae was originally described from NorthCarolina (Berkeley 1874), and the name was recently epitypifiedby Su et al. (2011) on the basis of a specimen collected in Floridawww.studiesinmycology.org161
