Penicillium is almost everywhere, (soils) -The conidiophores are simple or branched and are terminated by clusters of flask-shaped sterigmata. The spores (conidia) are produced in chains from the tips of the sterigmata - Penicillium is almost everywhere, (soils) -The conidiophores are simple or branched and are terminated by clusters of flask-shaped sterigmata.
