Otidea concinna

Spores: The spores are smooth, ellipsoid, 10--12 x 5--6.5 µm, and contain two large oil drops.

Conservation Status: Not of concern

Identification Notes:

The name Otidea is derived from the Greek word for ear and refers to the shape of the fruitbodies which, in some species, is much like that of a rabbit ear. Other species look as though the top part of the ear had been chopped off. Otidea concinna (= O. cantharella (Fries) Quélet and Flavoscypha cantharella (Fries) Harmaja) belongs to the latter group. It has bright yellowish fruiting bodies that occur singly or close-together in groups. The paraphyses are slender, bent at the tips, and encrusted with yellow material. Similar dull yellow or yellowish brown species include O. microspora (Kanouse) Harmaja (= O. alutacea var. microspora), dull yellow, with spores 9--10 x 5--6.5 µm, and O. alutacea (Persoon: Fries) Massee, pale yellowish brown, with spores 14--16 x 7--9 µm. Differentiating among these species is not a simple task and reliable distribution information will not be obtainable until the species concepts are better defined, including consideration of molecular data.
