Flecht. u. Myxom. p. 2G0), gonidia Verrucariaceorum forinas onmiiio diver- 

 sas pra?bere. Cui notaei — sive lichenes integral plantae sint, sivc (tit vult 

 theoria Schwendeneriana) consortium algarum fungorumque — magnam vim 

 tribuere debemus. Ex ilia veteris Verrucar'm generis altera pars ad Ar- 

 chilichenes nostros pertinet, familiam Verrucariaceorum (sens, strict.) consti- 

 tuens; altera ad Sderolklieues referatur sitque familia Pyrenulaceorum. 



Genus Pohjblastiaruiu, cujus species scandinavicas succincte exponere 

 hac vice suscepimus, ad ArcMlichenum classein pertinet. Quo modo a 

 ceteris ejusdeni classis generibus distinguatur, ex hac dispositione synoptica
