Description
 
 

Hare’s Ear is a medium-sized, lopsided, ear-like, cup fungus. It occurs throughout Europe and in parts of North America. In the United States it occurs from the northeast to the upper Midwest and on the West Coast. It is not common in Minnesota. It appears from spring to early fall, usually clustered, occasionally alone or scattered, in deciduous and mixed woodlands. It grows on the ground under hardwood and coniferous trees. It obtains its nutrients from decaying plant matter (saprobic).

The fruiting body is 2¾ to 4 (5 to 10 cm) long, 1½ to 2 (4 to 6 cm) wide, and spoon-shaped, ear-shaped, or cup-shaped. There are 46 species of Otidea. Some are said to be “ear-like”, erect and elongated with one side open, like a rabbit’s ear, while others are “truncated”, cup-like. However, in practice this character is difficult to determine. Otidea onotica is said to be one of the ear-like species. Like all Otideas, the cup is split down one side. The margins are rolled inward at first but flatten at maturity. The inner (fertile) surface is smooth and brownish-yellow to orange or orangish-buff. It often has a pinkish or rosy tint when fresh. The outer surface is slightly rough to the touch and is colored the same but without the pinkish or rosy shade. There is sometimes a whitish, hairy or downy, up to (1 cm) long stalk at the base. The spore print is white. The flesh is yellowish, thin, and brittle. Some sources say that it is edible, others that it is inedible.

Family Shuffle

As currently circumscribed, the family Pyronemataceae contains about 500 species in 75 genera, about half of all species in the order Pezizales. This large family has long been known to be problematic, and several attempts have been made to restrict it.

In 1968 (Rifai) the family Otideaceae was erected to include five genera of Pezizales, including Otidea.

In 1972 (Korf) Otideaceae and two other families were folded into a single large family Pyronemataceae.

In 1989 (Kimbrough) the family Otideaceae was resurected.

A molecular phylogenetic study published in 1997 (Landvik et al.) suggested the genera in Otideaceae belonged in Pyronemataceae, and in 2006 (Eriksson) genera formerly in Otideaceae were moved to Pyronemataceae.

A phylogenetic study published in 2007 (Perry) showed that Pyronemataceae as then circumscribed was not composed only of a single common ancestor and all of its descendants – it was not monophyletic – and is therefore invalid.

Today (2021) the problem remains unresolved. Many taxonomists place the genus Otidea in the family Otideaceae. Most, including Index Fungorum, continue to place it in Pyronemataceae.
