Link incluyó en su trabajo tres especies: Penicillium candidum, P. expansum y P. glaucum.John I. Pitt dividió el género en cuatro subgéneros en una monografía de 1979: Aspergilloides, Biverticillium, Furcatum y Penicillium. Penicillium chrysogenum is a widely studied species of Penicillium and is sometimes known as P. notatum, P. meleagrinum,or P. cyaneofulvum (3) though occasionally they are not synonymous. It also refers as “Doctor Fungi” as few members of the genus (Penicillium) can produce antibiotic to inhibit the growth of certain bacteria. Order: Eurotiales Those species for which the sexual phase is known are placed in the Eurotiales. Penicillium is a genus consisting of a group of fungi having around 354 accepted species. Penicillium colonies range in colour from blue-green to white, yellow and pink with a velvety or powdery texture. Phialides are usually flask-shaped, consisting of a cylindrical basal part and a distinct neck, or lanceolate (with a narrow basal part tapering to a somewhat pointed apex). Morphology in the past has been central to the taxonomy of Penicillium and along with multigene phylogenetics and extrolite profiling comprises the polyphasic species concept adopted for Penicillium. Those species for which the sexual phase is known are placed in the Eurotiales. (1981), Ramirez (1982), Samson et al. It was used to create the first antibiotic.

The hyphae run in all directions on the substratum and become intertwined with one […] These are having a heterotrophic or saprophytic mode of nutrition. Penicillium chrysogenum reproduces by forming dry chains of spores known as conidia, from a thread-like, brush shaped structure known as conidiophore. One of the things Penicillium is most famous for is the drug penicillin. Penicillium chrysogenum. The conidiophores give rise to the secondary branches (Metullae) that further give rise to the tertiary branches (Phialides or Sterigmata), which makes it distinct from the other groups of fungi. This is not only because new species were described since the late 1990’s, but was also a reflection that many species previously considered synonyms based on morphology were shown to be phylogenetically distinct.
