Carroll MELRA, 16 Sep. 2009 (ICMP 18543).* <strong>Colletotrichum</strong> asianum Prihastuti, L. Cai & K.D. Hyde,Fungal Diversity 39: 96. 2009. Fig. 17.Prihastuti et al. (2009) provide a description of this <strong>species</strong>.Geographic distribution and host range: Known on Mangiferaindica from Australia, Colombia, Japan, Panama, Philippines, andThailand; also rep<strong>or</strong>ted on Coffea arabica from Thailand.Genetic identification: <strong>Colletotrichum</strong> asianum is distinguished fromall other taxa using any of the genes tested, including ITS.Notes: Although the type specimen is from coffee, this fungus is isolatedcommonly from mango (Mangifera indica) (e.g. M<strong>or</strong>phological Group1 from Than et al. 2008; IMI 313839 from Australia; MAFF 306627from Japan). Isolates referred to <strong>Colletotrichum</strong> indet. sp. 1 by Rojaset al. (2010), also associated with mango fruit rots, again match C.asianum. Based on ITS sequences, isolates Man-63 and Man-69cited by Afanad<strong>or</strong>-Kafuri et al. (2003) from mango from Colombia, areprobably also C. asianum. Several papers have rep<strong>or</strong>ted geneticallyunif<strong>or</strong>m populations of C. gloeosp<strong>or</strong>ioides associated with M. indicaaround the w<strong>or</strong>ld (e.g. Hodson et al. 1993, Alahakoon et al. 1994,Sanders & K<strong>or</strong>sten 2003) and these perhaps also represent C.asianum, although DNA sequences are not available to confirm this.142
