VERRUCARIE^. 48 



This is the plant spoken of in E. Bot. Suppl. under 

 Ve7'r. rhyponta, 2597, fig. 2, as found on beech bark, in 

 the New Forest, by Mr. Lyell. It is very distinct in 

 general appearance from either of the two preceding 

 species. Pcrithecium dimidiate, carbonaceous, black, 

 inner tunic pale, nucleus white. Except that the nucleus 

 is not black, this plant assimilates to the description of 

 V.pulla, Ach., L. Univ., 281. I could not detect the 

 asci, but from the pulpy mass remaining after the dis- 

 charge of the sporidia, I have no doubt of their existence.

Asci linear, rounded at the apex ; sporidia in a single 

 series ; apothecia very large, few, scattered, not crowded 

 as in V. biformis; perithecium dimidiate, inner tunic pale 

 brown. Thallus of a duller white, or rather cream-colour, 

 than in V, biformis. 



Specimens labelled V. alba, by Rev. Churchill Babing- 

 ton, from Sussex, and Hartshill Hays, Warwickshire, 

 (Plate XVIII. fig. 5,) have proved, on examination, to 

 possess characters identical with this. I have never seen 

 any plant with entire perithecia described by Fries as
