Extract from Wikipedia article: Boletinellus merulioides, commonly known as the ash-tree bolete, is a species of bolete fungus in the family Boletinellaceae . Described as new to science in 1832, it is found in Asia and eastern North America, where it grows on the ground near ash trees.
Boletinellus merulioides is a species of fungus that belongs to the family Boletinellaceae. It is characterized by its small to medium-sized fruiting bodies, typically 2-6 cm in diameter, with a wavy or lobed cap and a short, stout stem. The cap surface is often wrinkled or veined, and the flesh is white or pale yellow. In East and Central Texas, B. merulioides has been found growing on the ground in association with oak trees, particularly in areas with rich soil and abundant leaf litter. It typically fruits from spring to fall, with peak activity during the summer months. The fungus is considered rare in the region, but can be locally common in suitable habitats.
