Was unable to get measurements before mushrooms began to deliquesce. Substrate was a well rotted hardwood log. Likely Oak. Temperatures were mid-to-upper 80s, high humidity, with rainfall the day prior. What was NOT collected, had completely deliquesced within 24 hours or less. Habitat is a low-lying drainage area, adjacent to a rock quarry. Lots of flooding debris on the ground, and heavy tree cover. Trees present are mostly Oak, Hickory, Elm, and Cottonwood.
