THE SPORE-SAC FUNGI 



509 



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. 



Peziza scutellata. Linn. 



The Shield-Like Peziza. 



Becoming plane, vermillion-red, externally paler, hispid towards the margin 

 with straight black hairs. Spores ellipsoid. Found on damp rotten logs from 

 July to October. Very plentiful and very pretty under the magnifying glass. 



Figure 433. Peziza scutellata. Very small but will show form under the glass.
