The [[thallus]] ([[mycelium]]) consists of highly branched networks of [[multinucleated]], usually colourless [[hyphae]], with each pair of cells separated by a [[septum]]. [[Conidiophores]] are at the end of each branch accompanied by green spherical constricted units called [[conidia]]. These propagules play a significant role in reproduction; conidia are the main dispersal strategy of these fungi.<ref>{{Cite journal | vauthors = Pitt J |date=1985 |title=A laboratory guide to common Penicillium species |journal=Mycologia |volume=79 |page=491 |doi=10.2307/3807483 |jstor=3807483 |s2cid=84610634}}</ref>

Sexual reproduction involves the production of [[ascospore]]s, commencing with the fusion of an [[archegonium]] and an [[antheridium]], with sharing of nuclei. The irregularly distributed [[ascus|asci]] contain eight unicellular ascospores each.
