 Parasola auricoma is a saprobic species, and so obtains nutrients by breaking down organic matter into simpler molecules. The fruit bodies grow either singly or in groups, often in large numbers, at road sides in deciduous forests, or on grassy areas. The mushrooms are short-lived, usually lasting only for a few hours before collapsing. Common in Europe and North America (including Hawaii), it has also been recorded from Japan. In Europe, fruit bodies appear most commonly in spring and summer months, while in North America, fruiting is more common in the late summer and autumn, after rains.
