31. Platysvia glaucuin var. nov. platyphylla Stevenville, on spruce, sterile. 

 This material, with some collected in Newfoundland by Waghorne and now pre- 

 served in the Eckfeldt herbarium, represents a distinct morphological variety, 

 not previously recognized, to which I am giving the name platyphylla on account 

 of its large lobate thallus and peculiar lacunations. The type No. 2483 is in the 

 author's herbarium, a portion of which was also sent to Dr. W. G. Farlow to be de- 

 posited in the herbarium of the Botanic Museum, Cambridge. This variety may be 

 described as follows: Thallus platyphyllus, cum lobis rotundis, non laceratis 

 et cum rugis acutis in superiore latere, non reticulato-cellulosus ut in Platysma 

 lacunosa typica, etiam non laceratus aut lacunosus ut in Platysma lacunosa var. 

 atlantica Tuck. It has the diagnostic nitidens under surface of glaucuin, not dull 

 beneath as in lacunosa. '■"
