Plants gregarious, scattered or cespitose, sessile or stipitate, 
fleshy, bright-colored, smooth or clothed externally with delicate 
white mycelium ; asci cylindric, 8-spored ; spores ellipsoid, at first 
smooth, at maturity reticulate. 
Type species, Peziza anrantia Pers. 
Spores not marked with ring at either end. 
Plants sessile, at maturity large, reaching a diameter of several cm. 
A. auranlia. 
Plants stipitate, medium-sized, seldom exceeding 1 or 2 cm. in diameter. 
Plants occurring in coniferous woods, stems usually long and spring- 
ing from a dense mass of white mycelium A. rhenana. 
Plants occurring among mosses in deciduous woods, stems short and 
not springing from a dense mass of white mycelium....^, rutilans.

? Aleuria wisconsinensis Rehm, Ann. Myc. 2 : 34. 1904. 
Plants gregarious or cespitose, at first globose, opening with a 
circular aperture and gradually expanding, at maturity varying 
in size from a few mm. to 5 or 6 cm. (rarely even larger), shal- 
low cup-shaped and usually regular in form when young becom- 
ing irregular and often variously contorted with age, often from 
mutual pressure, rarely one sided and Otidea-\ike, occasionally 
discoid with the hymenium almost plane, bright-orange within, 
color fading in dried specimens, externally whitish-pruinose ; asci 
cylindric or subcylindric, 12-15^ in diameter and 175-250 /z long; 
spores 1 -seriate, usually obliquely arranged in the ascus with the 
ends often overlapping, at first smooth and usually containing two 
(rarely more) large oil-drops, at maturity rough, roughenings 
taking the form of reticulations which are shallow and usually 
with one, rarely two, prominent projections at either end, 18-22 
X9-10/4 when mature, a little smaller when young; paraphyses 
strongly and rather abruptly enlarged above, often with the ends 
subglobose, reaching a diameter of 7 or 8ft, filled with orange 
granules. 
On naked soil in woods or open places, often on clayey soil.
