EARED PEZIZA. 



TAB. CVII. 



HpHIS adheres to the bark of old elder and willow trees, by 

 ■*■ a fmall central root or umbilical cord. The whole plant 

 is of a dark olive colour, and afTumes great variety of fhapes, 

 depending on its age, or the drynefs or moiftnefs of the air. 

 When young, and in a moift ftate, it is frequently turbin- 

 fhaped, as at a. when further advanced in growth, in rainy 

 weather, it is greatly extended in magnitude, becomes lobed 

 and undulated; the lobes lying over one another. The fub- 

 ftance quaking and gelatinous, of a dufky kind of olive 

 colour, and two or three, fometimes four inches in diameter j 

 it appears in this ftate, as at b. In dry fealbns it flirinks up, 

 and becomes of a coal black colour, as at c. The upper fide 

 is conftantly fmooth ; the under lide has a kind of hairinefs or 

 granule upon it, which gives a gentle afperity to the touch. 



Hudson makes it a Tramella, as did Linn^us in fome 

 of his works. Do not the Tremellce and the Pezizce touch 

 one another in this plant ? 



Grows about Halifax, but is rare. The fpecimen here 

 figured and defcribed, I gathered on the bark of an old willow 

 tree, by Red-Beck, near Shibden-Hall, in February, 1789.
