Chlorocephala means green head. However, the entire plant is green.
They grow in clusters, pileus round, depressed, somewhat translucent, more or less waxy, margin incurved, dark-verdigris-green, sometimes rather dark-green.
The stem is rather short, almost equal; green, but often paler than the cap, covered with fine powdery dust, often twisted.
Asci cylindric-clavate, apex rather narrowed, 8-spored, spores smooth, hyaline, ends acute, often slightly curved, 17–20×5µ.
The specimens in Figure 426 were found in Purgatory Swamp, near Boston, by Mrs. Blackford. Both cap and stem were a deep verdigris-green. They were sent to me during the warm weather of August.
Peziza. Linn.
Peziza means stalkless mushroom. This is a large genus of discomycetous fungi in which the hymenium lines the cavity of a fleshy membranous or waxy cup. They are attached to the ground, decaying wood, or other substances, by the center, though sometimes they are distinctly stalked. They are often beautifully colored and are called fairy cups, blood cups, and cup fungi. They are all cup-or saucer-shaped; externally warted, scurvy or smooth; asci cylindrical, 8-spored. The genus is large. Prof. Peck reports 150 species. Found early in spring till early winter.
Peziza acetabulum. Linn.
Reticulated Peziza. Edible.
Acetabulum, a small cup or vinegar cup. The spore-bearing body stipitate, cup-shaped, dingy, ribbed externally with branching veins, which run up from the short, pitted and hollow stem; mouth somewhat contracted; light umber without and darker within. Found on the ground in the spring.
