Trichothecium roseum is a fungus in the division Ascomycota first reported in 1809.[1] It is characterized by its flat and granular colonies which are initially white and develop to be light pink in color.[1] This fungus reproduces asexually through the formation of conidia with no known sexual state.[1] Trichothecium roseum is distinctive from other species of the genus Trichothecium in its characteristic zigzag patterned chained conidia.[2] It is found in various countries worldwide and can grow in a variety of habitats ranging from leaf litter to fruit crops.[2] Trichothecium roseum produces a wide variety of secondary metabolites including mycotoxins, such as roseotoxins and trichothecenes, which can infect and spoil a variety of fruit crops.[1] It can act as both a secondary and opportunistic pathogen by causing pink rot on various fruits and vegetables and thus has an economical impact on the farming industry.[1] Secondary metabolites of T. roseum, specifically Trichothecinol A, are being investigated as potential anti-metastatic drugs. Several agents including harpin, silicon oxide, and sodium silicate are potential inhibitors of T. roseum growth on fruit crops.[3][4][5] Trichothecium roseum is mainly a plant pathogen and has yet to show a significant impact on human health.[1]
