Magnified at 970x, this 1971 photomicrograph depicted a number of Penicillium glabrum
conidiophores of a Penicillium glabrum
fungus. The fungal conidiophore is a stalked structure, the distal end of which produces the asexual spores, known as conidia, through a process of budding. Conidia are apparent as very small round structures clustered like grapes at the end of these conidiophores.
