Genidentity coupled with material continuity is proposed as a minimum conception of biological individuality, and then theoretical individuation is employed to identify multiple kinds of biological individuals in a single example from mycology, a patch of chanterelle mushrooms. Of the many candidate materially continuous genidenticals found in a mushroom patch, only those with functional roles in biological theory are notable as biological individuals. Evolutionary and physiological theories pick out multiple kinds of functional individuals in mushrooms, so a pluralistic account of mushroom individuality is warranted.
