Extract from Wikipedia article: Tylopilus griseocarneus is a fungus of the family Boletaceae. Described as new to science in 1989, it is found in the coastal plains of southern New Jersey and southern Louisiana in the United States, where it grows in sandy soil under oak and pine trees. Its fruit bodies have a convex, pale charcoal-colored cap measuring 4.3–11 cm (1.7–4.3 in) and 1.5–3 cm (0.6–1.2 in) thick.
Tylopilus griseocarneus is a species of bolete fungus that grows in association with oak trees. In East and Central Texas, it typically fruits from June to October, producing medium-sized caps that range in color from grayish-brown to reddish-brown, often with a metallic sheen. The pores are small and angular, and the stems are slender and colored similarly to the cap. It is commonly found in wooded areas with abundant oak trees, particularly in the Post Oak Savannah and Blackland Prairie ecoregions of East and Central Texas.

Texas, September 14, 2022Observations of Tylopilus griseocarneus in East and Central Texas reveal the fungus grows in various locations, including Sam Houston National Forest and Hensel Park. The dark grey bolete mushrooms were found on Caney Creek Trail and other areas, with sightings recorded from June to September between 2018 and 2022. The mushrooms' pores, cross sections, and undersides were observed, noting the characteristic blackening of the cross section after a short period. Some specimens showed signs of infection by Hypomyces. The fungus was consistently found in the same general area, suggesting a specific habitat preference. The observations provide valuable information on the growth patterns and characteristics of Tylopilus griseocarneus in East and Central Texas. Overall, the data suggest a relatively consistent presence of the species in the region during the summer months.
