Calostoma Lutescens: A Rare Mushroom Find

While hiking in the Ouachita National Forest, I noticed a bright yellow spot on the forest floor. It was a pair of Calostoma lutescens, a species occasionally found in the southern Appalachians. There they were, side by side, resting on a bed of damp leaves with sunlight filtering through the trees.

I photographed them, focusing on their unique texture and color. The tall yellow stalks had a fibrous, textured appearance, and their rounded spore sacs contrasted with the green and brown of the forest floor.

Identifying them was straightforward. The online foraging community quickly pointed me to Calostoma lutescens. Though not toxic, this species is rarely eaten, and caution is always recommended with any wild fungus.
