Microfungi associated with non-infected and infected leaves of Colocasia.
Healthy C. antiquorum leaves and those infected by Phytophthora colocasiae harboured distinct phylloplane microflora. Actinomucor repens, Aspergillus terreus, Curvularia tuberculata, Mucor racemosus and white sterile hyphae were restricted to non-infected leaves, Colletotrichum sp., Humicola brevis, Memnoniella echinata and Nigrospora sphaerica to blighted ones. Alternaria alternata, Aspergillus humicola, A. niger, Curvularia lunata [Cochliobolus lunatus], Curvularia pallescens, Fusarium sp. and Sclerotium sp. occurred occasionally on healthy leaves but were frequent on blighted ones.
