For example, the gasteroid genus "Hymenogaster" has been shown to be closely related to agaric genera such as "Hebeloma", which were formerly placed in family Cortinariaceae or Strophariaceae. This is found by DNA analysis and also indicated on a microscopic scale by the resemblance of the spores and basidia. According to a current classification system, "Hebeloma" now belongs to family Hymenogastraceae, and is considered more narrowly related to the closed "Hymenogaster" fungi than, for instance, to the ordinary mushrooms in genus "Cortinarius".
