Agaricus rhoadsii

AI-generated description

Agaricus rhoadsii is a species of mushroom that typically grows solitary or in small groups in fields, meadows, and along roadsides. In East and Central Texas, it has been found to fruit from May to October, often in association with oak, elm, and ash trees. The cap is 3-6 cm in diameter, convex to flat, and tan to brown in color, while the gills are free and pinkish-brown. The stem is 3-6 cm long and 0.5-1.5 cm thick, with a ring that is often absent or faint. The flesh is white and has a mild, sweet odor. It is considered an edible species, but caution should be exercised due to potential confusion with poisonous lookalikes.

AI-generated summary of observations

Observations of the fungus Agaricus rhoadsii in East and Central Texas reveal its presence in Lick Creek Park and Hensel Park, both in College Station, Texas. On June 10, 2018, mushrooms were found in Lick Creek Park, with photographs taken from various angles, including a dissected specimen. Similarly, on May 8, 2023, mushrooms resembling Agaricus rhoadsii or possibly A. placomyces were discovered in Hensel Park, growing under oak bushes. Photographs of these specimens, including side views and cross-sections, were taken to aid identification. Spores collected from the Hensel Park specimen were also examined, potentially helping to confirm the species as either Agaricus rhoadsii or A. placomyces. The observations suggest that Agaricus rhoadsii may be present in the region, although further confirmation is needed to rule out other similar species.
