B. plumbed (Lead-coloured Bo vista). 



Lycoperdon giganteum (Giant Puff-Ball). In the autumn 

 of 1873, we found a specimen of this species measur- 

 ing 387 inches in horizontal circumference, by 31 in 

 vertical circumference, and weighing 6 Ibs. 



L. ccelatum (Collapsing Puff-Ball). 



L. pyriforme (Pear-shaped Puff- Ball). 



Cyathus striatus (Striate Cyathus). 



MorcJiella esculenta (Common Morel). 



M. semilibera (Half-free Morel). 



Peziza onohea (Orange-ear Peziza). 



P. aurantia (Orange Ground Peziza). 



P. ccerulea (Blue Peziza). 



P. elegans (White and red Peziza). 



P. aruginosa (Green Peziza). This species has the 

 singular property of conferring considerable con- 

 ventional value on fragments of decaying wood. 

 It attacks small broken branches of oak and beech, 

 which, when thoroughly permeated by the mycelium 

 or spawn of the fungus, assume a beautiful mala- 

 chite-green, and, in this state, are manufactured into 

 a variety of very pretty ornaments. When properly 

 prepared, the wood admits of being easily turned 

 in a lathe, or sawn out into very thin slips with 

 which the covers of blotting-cases and ladies' work- 

 boxes are veneered. 



Tuber cestivum (Common Truffle). 



T. rufum (Red Truffle). 



Ustulina vulgaris (Common Ustulina). 



SpJieria Fraxinea (Ash Spheria).
