140 Mr. Turner's Descriptions of Eight New British Lichens, 



powdery, or rather granulated warts, which soon become con- 

 fluent, and not unfrequently cover the whole surface. The 

 true fructification, which is very sparingly produced, is widely 

 different from these, or indeed from the fruit of any other Va- 

 riolaria at present described ; so that the plant might, before it 

 is accurately examined, be regarded as constituting a new ge- 

 nus. It consists of smooth white globules, bearing considerable 

 resemblance to some of the smaller Lycoperdons, nearly equal in 

 size to a common pea, at first perfectly spherical and closed, 

 but soon discovering an impression in the centre covered with a 

 thin membrane, which gradually enlarges, till at length it 

 bursts, and the propagula falling out, leave the appearance of a 

 large concave scutella, not unlike that of Lichen spongiosus 9 

 Eng. Bot. with a thin lacerated margin, and deep green, waxy disk. 

 Mr. Borrer observes respecting this plant that it has been supposed 

 to be the perfect state of V.faginea, and is scarcely distinguish- 

 able from that species, except by its wholly panting the bitter 

 taste, and by its remarkable receptacles, which are by no means 

 generally produced. He adds that he has reason to believe that 

 V.faginea, when perfect, produces something similar to these, 

 which are perhaps the proper fructification of the genus, Variolaria, 

 the contents of the powdery warts being, probably, analogous 

 to gemmae.
