 nfh-trees, in a flood-foil, by waters, frequent, in April and May, 

 after warm fhowers. In C/^w-wood, on the banks of South-Tyne, 

 near Allerivajh. On the banks of North Tyne, near Chipchace ; alfo 

 on the banks of the brook at Simonburn. The pedicle is fhort, 

 thick, wrinkled, tubulous, and white. The head is of a diffe- 

 rent form, according to its different ftages of growth, fituation, 

 and flate of the feafon ; fometimes like a tall pyramid, fwelling 

 at the bafe ; fometimes like a fhort, ventricofe obtufe cone, and 

 fometimes like a long acute one ; always with numerous cells, 

 larger or fmaller, according to its fize, forming a beautiful re- 

 ticular work *. Under the fhade of afli and beach trees, on the 

 edge of the brook oppolite to the upper end of the rectory-dea 

 at Simonburn^ in a rich fandy loam thrown up by torrents or 

 floods, I have gathered it fo large, as to weigh a quarter of a 

 pound, in the middle of a mild May, warm, with gentle mowers. 

 It is of a yellowifh-white, and changes by age to a pale reddifli- 

 yellow, and in drying to a ftraw-colour. Snails are very fond of 

 it, and there are commonly fome within the large ones, which 

 eat them up by degrees, if not gathered.
