Extract from Wikipedia article: Helvella macropus is a species of fungus in the Helvellaceae family, Pezizales order. Ascocarps can be found in summer and autumn in woodland, usually (though not exclusively) associated with broad-leaved trees. The slender stem, up to 5 centimeters high, supports a cup shaped cap, the whole fruiting body being pale grey or brown, the inner (hymenial) surface of the cup usually being darker.
Helvella macropus is a species of fungus in the family Helvellaceae, characterized by its large, pale brown to tan cap with a wavy or lobed margin, and a long, slender white stem. In East and Central Texas, it typically fruits in late winter to early spring, often in association with oak trees, particularly Quercus stellata and Quercus buckleyi. It can be found in a variety of habitats, including wooded areas, woodland edges, and along streams, where rich soil and moist conditions prevail. The fungus produces ascospores that are elliptical in shape and measure 18-22 x 10-12 μm.
