This is an abundant species, and very distinct from any of 

 the others. It was found by Mr. Ralfs, Mr. Jenner, and 

 myself, within a few days of each other.

 usually of a green colour. Cells very many times as long 

 as broad. Sporangia cruciform, and about one half the size 

 of those of St. virescens.

 down Forests : Mr. Jenner. 



This species I have myself met with several times, but did 

 not at first recognize its distinctness, of which, however, I 

 now entertain no doubt : and it was only on the receipt of a 

 beautiful sketch from Mr. Jenner, accompanied by remarks, 

 that I examined thoroughly into the matter, and satisfied 

 myself of its entire distinctness.
