Penicillium are saprophytic fungi. They are commonly known as blue-green mould. They belong to Ascomycota. The mycelium consists of highly branched, multinucleated and septate hyphae. Chains of conidia are present terminally, which gives it a brush like appearance. Asexual spores are produced exogenously and sexual spores, i.e.. ascospores are formed endogenously. They are an important source for the production of antibiotics and organic acids.
