Drawings of spores found in air.
Some are common targets of research on asthma (Alternaria alternata), while many are not (Laccaria laccata, Epicoccum nigrum). A drawing of a very small “dust” seed (Orchis masculata) is provided for comparison. A = ascospore, B = basidiospore, M = mitospore. Figure adapted from [30].
