Extract from Wikipedia article: Albatrellus subrubescens is a species of polypore fungus in the family Albatrellaceae. The fruit bodies (mushrooms) of the fungus have whitish to pale buff-colored caps that can reach up to 14.5 cm (5.7 in) in diameter, and stems up to 7 cm (2.8 in) long and 2 cm (0.8 in) thick. On the underside of the caps are tiny light yellow to pale greenish-yellow pores, the site of spore production. When the fruit bodies are fresh, the cap and pores stain yellow where exposed, handled, or bruised.
Albatrellus subrubescens is a species of fungus that belongs to the family Albatrellaceae. It is a small to medium-sized polypore with a reddish-brown to tan cap, often with a velvety texture, and white to yellowish pores. In East and Central Texas, it typically grows on the ground in association with oak and pine trees, particularly in sandy or clay soils. Fruitings are usually solitary or scattered, and can be found from summer to fall. The fungus is edible, but not widely sought after due to its small size and variable flavor.

AI-generated summary of observations
Observations of Albatrellus subrubescens in East and Central Texas show that the fungus grows on steep sides of small ravines, typically on exposed sand and clay soil partially covered by pine needles. It has been found on Sand Branch Loop Trail in Sam Houston National Forest near Montgomery, Texas, on multiple occasions between 2021 and 2023. The mushrooms often co-occur with Cladonia lichen and are characterized by a terrestrial polypore morphology with a pore surface. Cross-sections of the mushrooms reveal a pore layer 1-3 mm thick, and microscopic examination shows hyphae, spores, and basidia. The fungus appears to be persistent in the area, with observations made at the same location over a period of several years, including January 1, 2021, December 5, 2021, and December 22-24, 2023.
