The appearance of colonies of three Aspergillus species and Penicillium sp. and scanning electron microscopic observations of spore production. (A–C) Colonies of A. ochraceus, A. niger and A. flavus, respectively, after 5 days of growth on PDA + S. (D) Aspergillus ochraceus emerging from a cannabis inflorescence incubated under high humidity conditions for 3 days. (E,F) The spore-bearing structures (conidiophores) of Aspergillus consist of stalks upon which are produced a mass of spores formed in chains, as seen in (G–I). (J) Growth of Penicillium species on the surface of a cannabis inflorescence kept under high humidity for 5 days appears as a whitish-blue mycelial growth. (K,L) Spores of Penicillium sp. are produced in chains at the tips of conidiophores and are produced from structures called phialides (arrow).
