Notes: Coccomyces dentatus (Rhytismataceae) is a minute fungus growing on Oregon-grape (Mahonia nervosa) leaves. Individual colonies start from a single spore that germinates, and the fungal filaments spread until they reach another colony. When this happens, both colonies stop their growth on a contact zone and the boundary between them appears as a black line. With several individual colonies, the infestation on the leaves looks like an irregular network of discolored patches. The black dots that look like little stars are fruiting bodies that open, showing several fine rays. On southern Vancouver Island, naturalists noticed this fungus a long time ago, and the first collection was made by John Macoun in 1915.
