Harzianum Green Mould
A widespread soil and wood fungus, best treated as a species complex (T. harzianum sensu lato, THSC). Strains are used as biocontrol agents in commercial biopesticides, but on mushroom farms it is a green mould competitor, especially on shiitake logs and blocks, and also in button and oyster mushroom substrates. It was first blamed for the 1985 Agaricus green mould epidemic, later shown to be T. aggressivum.
