Which spores are characteristic of penicillium?

Penicillium species are characterized by their conidia, which are typically produced in a brush-like arrangement on specialized structures called conidiophores. The conidia are usually small, globose to elliptical, and can vary in color, often appearing green, blue, or white. Additionally, the presence of septate hyphae is a key feature of Penicillium. These characteristics help in the identification of various Penicillium species in laboratory settings.
