Figure 444.—Crucibulum vulgare.
The peridium is tan-colored, thick externally nearly even, internally quite even, smooth, shining; mouths of young plants are covered with a thin yellowish membrane called the epiphragm. When old the cups bleach out and lose their yellow color. The peridioles or eggs are white, that is they are covered with a white membrane. Their yellowish color and white eggs will readily distinguish this species.
They are found on decayed weeds, sticks, and pieces of wood. The specimens in the halftone grew on an old mat and were photographed by Mr. C. G. Lloyd.
Nidularia. Tul.
The peridium is uniform, consisting of a single membrane; globose, at first closed, finally ruptured or opening with a circular mouth.
The sporangia are quite small and numerous, not attached by a funiculus to the peridium, enveloped in mucus.
Nidularia pisiformis. Tul.
