The section of the perithecium has a peculiar square 

 shape, nucleus brown. 



In Mr. Borrer's herbarium is a specimen unnamed ! 

 sent by Mr. Harrimann, from the north of England, in

 shape, uniseptate, bright-brown, half the size of those of 

 V. gemriiifera. (See Plate XX. fig. 4.)

 occurs in the herbarium of the Rev. Churchill Babington, 

 St. John's College, Cambridge, gathered by him at Loch 

 Coriskin, Skye. Notwithstanding the colour of the 

 thallus, the different size and number of the sporidia, 

 there cannot be a doubt but that both are referable to 

 V, gemmifera.

 a green stratum underneath, cracked into rather large 

 smooth areolae, which have their edges raised and 

 minutely crenulated or waved, thus giving the whole 

 plant a singular undulate appearance. Apothecia, one or 

 several on each areola, frequently crowded, small, very
