Tricholomas of North AmericaMore than 100 mushrooms in the genus Tricholoma have been reported in North America. Most are relatively large, showy mushrooms that grow on the ground near many species of temperate forest trees, both hardwoods and conifers. They typically fruit from late summer through early winter or even into spring in warmer areas. Some are fine edibles, including the matsutake. Others are inedible or even poisonous.
