Figure 432.—Peziza vesiculosa.
Often in thick clusters. Those in the center are frequently distorted by mutual pressure; large, entire, sessile, at first globose; closed at first, then expanding; the margin of the cup more or less incurved, sometimes slightly notched; disk pallid-brown, externally; surface is covered with a coarsely granular or warty substance which plainly shows in the photograph. The hymenium is generally separable from the substance of the cap. The spores are smooth, transparent, continuous, elliptical, ends obtuse.
They are found on dung-hills, hot-beds or wherever the ground has been strongly fertilized and contains the necessary moisture. This is an interesting plant and often found in large numbers. Vesicolosa means full of bladders, as the picture will suggest.
I found a very nice cluster on the 25th of April, 1904, in my stable.
