Immersed in sand on the sea-coast, at the roots of Psamma. Autumn.

Cups 1 inch high and broad; rooting stem 2 to 3 inches long. The sand adheres so closely to the floccose exterior that it forms a complete coating. The whole plant is extremely brittle, and so much immersed in the sand as hardly to be recognized,

Name-aupos, sand, píλos, loving; from its preference for sandy soil.

The cup is rather shallow, an inch or more broad; margin entire except when old, when it becomes reflexed and split; the exterior near the base is longitudinally wrinkled; the stem is 1 to 2 inches long, immersed in the ground, ordinarily furnished with fibrils.

This species was for many years included as British on the authority of Dickson, but a specimen now exists in the herbarium of the Rev. M. J. Berkeley, figured by Dr. Cooke in "Mycogr."

Name-Rapulum, a little turnip; from the shape, especially of the stem.

Cup subsessile, externally pruinose, dimidiately elongated, or obliquely contorted, becoming incised on the one side. (Plate III. fig. 13.)

Name-wriov, a little ear; shaped like an ear.

ARRANGEMENT OF THE SPECIES.

Cup sessile, expanded, nearly cochleate, umber-brown paler externally, elongated on one side; asci cylindrical; sporidia 8, elliptic, asperate, 15 × 8μ; paraphyses linear septate, apices clavate, brown. (Plate III., fig. 13.)

Cup 1 inch wide, elongated on one side, divided nearly to the base on the shorter side; sporidia rough, with a central nucleus.

Name-Tλεuρóv, a side, ovç, an ear.

On the ground amongst leaves, in woods. Summer and autumn.

Cup 1 to 3 inches high and 1 to 2 inches broad, most variable in form, sometimes nearly equal-sided and entire, but generally elongated on one side; exterior pale fulvous; disc pale orange.

The species with which it is most easily confounded is Peziza leporina, from which it is always to be distinguished by the colour of the disc and the straight paraphyses.

Name-ovos, an ass; like the ear of an ass.
