_ on the coast; Mr. Bolander. With a thallus not ill- 
comparable with that of Z. conglomerata, Ach., this 
species offers acicular spores (Zbninia, Auct.) Para-

Lecipea massata (sp. nova) thallo glebuloso-verrucoso 
viridi-glaucesccnte ; apotheciis mediocribus, centro affixis

; iores, incolores. Loose gravelly soil on hillsides, 
‘ near the sea; Mr. Bolander. Spores best comparable 
with those of Z. granosa, (Obs. Lich.) but scarcely 
other than bilocular. Those of my English speci- 
mens of L. aromatica (Borr. Herb.) as well figured by 
Mudd (Man. Brit. Lich. t. 3, f. 64) are obtuse and 
Father finger-shaped, quadrilocular, and of twice the
