 cluded from Cooke's " Handbook." It is placed here on 

 the chance of some plant being discovered answering to 

 the description. 



Genus VI. — Mitrula. Fries. 



Receptacle globose or oval, even, immarginate, concrete 

 with the stem ; substance fleshy ; asci cylindrical, or 

 somewhat clavate ; sporidia 8, fusiform, hyaline. (Plate II.

Small slender plants, of which there are but six 

 species (now that Dr. Cooke has created the genus 

 Leploglossum), four of which are British, and are dis- 

 tinguished from Leotia by having no decided margin to 

 the receptacle, from Leptoglossum by the broader and 

 shorter capitulum, and from Spathulaiia by the capitu- 

 lum not being compressed.
