Colletotrichum gloeosporioides from eighteen Malaysian hosts, namely mandarin orange (Citrus reticulata ), cacao (Theobroma cacao), an orchid (Cattleya sp.), pepper (Piper nigrum ), chilli (Capsicum annum ), grass (Im p e ra ta cylindrica ), mango (Mangifera indica) and legume cover crops (P u e ra ria phaeseoloides, Centrosema pubescens, and Calopogonium mucunoides) and a weed (Mimosa p u d ic a ), vegetables (Psophocarpus tetragonolobus, Phaseolus vulgaris, Vigna ra d ia ta , Vigna sesquipedalis and Arachis hypogaea), a shrub (Leucaena leucocephala) and a herbaceous vine (Clitoria ternatea ) were examined fo r colony growth characteristics, morphology o f conidia, growth on various media and temperatures and pathogenicity on Phaeseolus bean hypocotyls. Conidium size o f Colletotrichum gloeosporioides was 14.25-19.0 x 2.7-5.03 fim. The appressorium size was 6.34-10.08 x 5.28-7.31 fim and the shape was globose/sub-globose/lobed. No correlation between the appressorium size and shape was noticed. The optimum temperature fo r growth was 28 and 30°C. None o f the isolates caused infection symptoms on Phaseolus bean hypocotyls.
