with ''P. phyllogena''. The former species had been described by Richard Korf in 1954; in that publication, Korf noted "It is perhaps our commonest large cup-fungus, and it seems to me that it must have been described before 1897 by some European or American author, but I have seen no types which match it." It is commonly known as the common brown cup, or the pig-ear cup.

of ''Peziza phyllogena'' are cup-shaped, measuring in diameter. The flesh is thin and fragile, and the sides of the cup are often compressed or lobed. The cups do not have a stem, and instead are attached to the substrate at a narrow central point on the bottom. The inner surface of the cup is dark purplish brown to dark reddish gray, while the outer surface is similar to the inner surface, or may have more purplish tones. The cup margin is thin, with a sharp edge, and it turns black as it dries. The edibility of the fungus was unknown, but Roger Phillips considers it edible. The

Habitat and distribution

''Peziza phyllogena'' grows solitarily or in dense clusters on soil or on well-decayed logs. Fruit bodies usually appear in early spring. The fungus has a widespread distribution in North America, especially the upper
