The fruitbodies of Morchella esculentoides are variable in size and shape, commonly 10 - 15 cm high but often larger, comprising a stalk and fertile upper part or cap, hollow. The cap is rounded, subglobose to ovoid, or sometimes more elongated and occasionally conical, ‘honeycomb-like’, comprising irregular fertile pits separated by a network of narrow sterile ridges or ribs, greyish to pale yellow-brown, delimited from the stem by a shallow furrow. The stem is well-developed, stout, whitish to cream, sometimes enlarged towards the base, and the surface is often somewhat furrowed and bearing fine scurfy scales especially towards the apex. The spore deposit is deep cream to yellowish, and spores are broadly ellipsoid, smooth and lacking internal oil drops. Close examination by Dr. Methven (see annotation above) combined with the 2015 DNA analysis confirmed that this specimen is Morchella esculentoides.
