Importance and distribution

Tripospermum species are often associated with sooty moulds. The mycelium forms black, effuse, epiphyllous crust like colonies on the surface of leaves (Hughes 1951). There are 33 Tripospermum epithets in Index Fungorum (2022), one species has been transferred to Clasterosporium and other species such as Tripospermum aurantii, T. cupaniae, T. lagerstroemiae, T. pannosum, T. pes-gallinae var. jambosae, T. roupalae, T. stelligerum are synonyms of Triposporium. Tripospermum is known on a wide range of hosts such as Abies firma (Pinaceae), Acacia auriculaeformis (Fabaceae), Acer sp. (Sapindaceae), Bromelia (Bromeliaceae), Eurya japonica (Pentaphylacaceae), Ficus (Moraceae), Malus domestica (Rosaceae), Metasequoia glyptostroboides (Cupressaceae), Phyllostachys (Poaceae), Pinus densiflora (Pinaceae), Pometia pinnata (Sapindaceae), Quercus serrata (Fagaceae), Rorippa amphibian (Brassicaceae) and others. Tripospermum has a wide distribution occurring in Asia (China, India, Japan, Malay Peninsula, Myanmar), Caribbean (Cuba), Europe (Poland), Oceania (Solomon Islands) and South America (Brazil, Venezuela).



Quarantine significance

Tripospermum is of quarantine concern as it causes disease of several economically important fruits and vegetables such as sooty mold of Dimocarpus longan L. (caused by T. porosporiferum) (Serrato-Diaz et al. 2010), sooty molds on Psidium guajava (Kwee 1988), sooty blotch disease of Malus (Wrona and Grabowski 2004) amongst others.
