Callistosporium purpureomarginatum is a species of fungus in the family Tricholomataceae. It is characterized by its small to medium-sized fruiting bodies with purple-brown caps and white to pale yellow stems. In East and Central Texas, this fungus has been found growing on the ground in wooded areas, often associated with oak and pine trees. The cap typically ranges from 1-4 cm in diameter and has a distinctive purple or reddish-purple margin. The gills are crowded and attached to the stem, and the spore print is white. This species is considered rare to uncommon in the region, but can be found during the fall season, particularly after rainfall.
