The image showcases a cluster of three white-gilled mushrooms with cream-colored flesh and pale brown markings on their caps. The underside of one mushroom is visible, revealing its gills.
It appears that these mushrooms may belong to the genus Russula, which includes several species known as "brittlegill" mushrooms due to their fragile flesh and tendency to crumble when handled.
These mushrooms were found in Winters Bayou in Sam Houston National Forest, east of Waverly, Texas, on June 11th. – AI vision
