AI-generated summary of observations

Lactarius subserifluus was observed in deep shade under various tree species, including black cherry, Maclura, and oaks, near a pond in Washington-on-the-Brazos State Historic Site. The fungus was also found on trails in Sam Houston National Forest, specifically on Winters Bayou Trail and Stubblefield section of Lone Star hiking trail. In Lick Creek Park, it was observed under large trees. The observations were made over several years, from 2019 to 2021, during the summer months (June to September). The fungus was found in various stages of growth, including young mushrooms and mature ones with visible gills on the underside. The observations suggest that Lactarius subserifluus prefers shaded areas with rich soil and abundant tree cover in East and Central Texas.
