SPH^ERIA CLAVIFORMIS. 



1 HIS is fomething like Bulliard's Hypoxylon clava- 

 tum, tab. 444. Jig. 5. differing chiefly in being rough 

 on the outfide. It grows from the inner bark of 

 rotten flicks, lacerating the outer bark, and feldom 

 holding more than one ovate capfule, which is fup- 

 ported in the middle of the head or clavated part 

 on an irregular Ifem. I have alwajs found it black, 

 except the middle coat of the capfule, which is white.

1 HAVE found this Spharia in great abundance in 

 fome parts of Keniington Gardens, where it grows 

 annually, beginning to fliow young plants about 

 January, at the fame time that the old ones are in 

 their lail decaying ftate. They feem to be truly 

 moncecious, firft producing a whitifli farinaceous 

 duif on the whole furface. It feems in perfedlion 

 about midfummer, when the fphccrula or capfules 

 are forming, and copioufly producing black feeds, 

 which they eje6t in autumn. In the younger ftate 

 the texture is fomewhat leathery, in the old very 

 fragile. Sometimes it fpreads into large patches 

 on old rotten trees.
