Importance and distribution

Metacapnodium species are sooty moulds and form black coating on the surface of leaves. They obtain nutrition from insect honeydew. The black hyphae screen out sunlight and reduce the rate of photosynthesis (Chomnunti et al. 2014). Metacapnodium comprises 14 species known on wide range of plants such as Ackama rosifolia (Cunoniaceae), Coprosma foetidissima (Rubiaceae), Cyathea medullaris (Cyatheaceae), Dacrydium cupressinum (Podocarpaceae), Durio zibethinus (Malvaceae), Hevea brasiliensis (Euphorbiaceae), Phyllocladus trichomanoides (Podocarpaceae), Podocarpus spicatus (Podocarpaceae), Prumnopitys taxifolia (Podocarpaceae), Psidium guajava (Myrtaceae), Taxus baccata (Taxaceae). Metacapnodium is widely distributed including in Asia (Malaysia, South Korea), Europe (Ireland, Sweden, United Kingdom), North America (Canada, West Indies, the United States), Oceania (New Zealand). Fresh collections of Metacapnodium are needed as molecular data is lacking.
