PART II. 



This paper is a continuation of tlie one published in these Reports^ 

 Vol. XIII. (1912), p. 254. 



Thirty-six species and varieties are enumerated, which belong to 

 the Xantho-Pseudocyphellatse group of the Stictacese. This group is 

 characterized by the presence of Pseudocyphellse on the under surface 

 of the thallus with soredia of various shades of colour, from citrine or 

 golden yellow, to cream or sometimes dingy-yellow. 



In several species, the medullary layer of the thallus is also of a 

 bright golden-yellow colour, which, together with the bright-green or 

 blue-green algal associates, give the plants an attractive appearance. 

 The individual specimens are fairly numerous in the various collections 

 examined, owing no doubt to the striking tints of colour attracting 

 the notice of the collectors.
