Spores (fig. 1) broadly ellipsoid, 1-septate, sometimes polari-bilocular (4), the loculi 
connected by a median canal, olive or brown, :0009" long, 0003” broad. Thecw 
8-spored, 
blue with iodine, 0036” long, 00075" broad. Paraphyses discrete, filiform, united by 
brown tubereulated heads. Apothecia marginal; in character, those of 
S. pulmonacea, Ach. Spermogones also identical with those of S. pulmonace 
site, external aspect, and internal constitution. Thallus most variable in size, 
eolour, smoothness, and other characters. 
6 to 12 inches and upwards in diameter, just as S. pulmonacea does. Occasio 
so smooth on the upper surface as to approach S. damecornis in this character ; 
deeply fossulate, without distinct intervening rugæ. Between these conditions t
