 nkotiann* crifpato nudo aureo, fubtus venojus palUde-ferrugcnius. 



TOBACCO HELVELLA. 



TAB. CLXXIV. 



THIS Helvella fometimes adheres by its whole underfide, to 

 dry wood and branches of trees, in a {bate of decay; fome- 

 times it is detached round the fides, and the margin much elevated, 

 fo that it feems*to adhere by a central bafe only. 



The upper furface is foft, and fmooth to the touch, but made 

 uneven by riling bunches, particularly in the larger fpecimens. 



The plant, both in colour and fubftance, very aptly refembles 

 the bell cured Spanifh tobacco, by which character, and its golden 

 margin, it is at once diftinguilhed. The figure is in general round, 

 the margin elegantly lobed ; the lobes crenated or dented, and 

 edged with a fine golden-coloured lace, 



The underfide is veined and wrinkled, naked and of a colour 

 fomewhat paler than the upper. The plant fometimes fpreads to 

 a confiderable diftance ; I have feen it run upon the decayed fhoots 

 of common woodbine or honeyfuckle, to the length of two or 

 three feet, in the manner exprefTed in the upper figure on the 

 plate. It is in perfection in February, and foon penfhes. It re- 

 fembles the Auricularia ferrugenia, of Bulliarl> ; but I think 

 it a diitinft fpecies.
