31. Thelotrema lepadinum. 



Adde syn. Thelotrema lepadinum, Schijer. Enuni. 225, 

 tab. viii, f. 5. h. c. (good.) 



Thelotrema exanthematicum, 



Adde syn. Thelotrema clausum, Schaer. Enum. 225. 



35. Segestrella thelostoma. 



Adde syn. Segestria umbonata- Schaer. Enum. 207, excl. 

 the synonymes of Verrucaria irrigua and erysiboda, 

 Tayl., and Ferr. ^55a, Tayl., which are totally different 

 from each other, and from Segestrella thelostoma., as an 

 examination of the authentic specimens in herb. Borrer 

 has shown. Verr. irrigua and erysiboda are, probably, 

 forms of the same plant, and are united as one species 

 in this work, under Ferr. irrigua. Ferr.^s^a, Tayl., 

 is an Endocarpon. Schserer's tab. viii, f. 1 does not 

 represent Segestrella thelostoma (as figured in E. Bot., 

 and the orig. spec, in herb. Borrer), but I suspect is 

 rather taken from a specimen of Verrucaria irrigua, 

 Tayl., gathered by lie v. T. Salwey, at Rhaidyr 

 Mowddach, of which I have a similar one in my own 

 herbarium.
