Colletotrichum fructicola

Colletotrichum fructicola Prihastuti, L. Cai & K.D. Hyde, Fungal Diversity 39: 98 (2009)

Index Fungorum number: 515409            Facesoffungi number: FoF0767            

 

Sexual morph: Undetermined. Asexual morph: Conidiomata absent on culture. Setae numerous, base pale to dark grey, with scattered, dark brown setae about 50–80 μm long. Conidiophores branched at the base, elongate, hyaline, smooth. Conidiogenous cells enteroblastic, phialidic, integrated, smooth, with minute collarette at the tip. Conidia 11–14 × 3–5 μm (x̅ = 12 × 4 μm, n = 40) hyaline, smooth or verruculose, aseptate, guttulate, fusiform, cylindrical with obtuse to slightly rounded ends. Appressoria not observed.

 

Culture characteristics: Colonies on PDA reaching a maximum of 80 mm diameter in 7 days at 25 ºC, at first white and becoming pale brownish to pinkish, reverse pale yellowish to pinkish, aerial mycelium greyish white, dense, cottony. Vegetative hyphae 2.1 μm hyaline, smooth walled, septate, branched.

 

 

Known distribution: Brazil, China, Japan, Korea, Puerto Rico, Thailand (Bhunjun et al. 2019, Cao et al. 2019, Costa et al. 2019, Hirayama et al. 2018, Veloso et al. 2018, Jayawardena et al. 2016.

 

Material examined: Thailand, Chiang Rai, on dead leaves of Rosa hybrida (Rosaceae), 15 May 2018, Ruvishika S. Jayawardena RKB5 (MFLU 18–1837, new host record), living culture MFLUCC 18–1160.

 

GenBank Accession No: ITS: MN788675, GAPDH: MN995327, CHS: MN995335, ACT: MN995333

 

Notes: Colletotrichum fructicola has a wide host and geographical range as well as a wide distribution and is a well-known pathogen on many crops (Jayawardena et al. 2016). A strain in this study clustered with the type species of C. fructicola. This is the first record of C. fructicola as a saprotroph on Rosa hybrida in Thailand.
