Wright. Apothecia comparable with those of forms 
ofthe group represented by B. auriyera (Fee) from 
which the present is separated by its pale hypotheci- 
um. Considered by themselves, the biatorine types 
of Lecidea, Ach., may well appear too intimately akin 
to the lecideine to admit of generical separation. In 
a larger view however it is snfficiently evident that 
two parallel series are exhibited in the family before 
us; andsuch separation may be accepted as most 
convenient, if not, with Fries ‘Zichenologiam idealiter 
intuenti,’ (I. EB. p. 247) as clearly necessary. In ac- 
cordance with observations already made, 1 regard 
the natural groups Biatora and Lecidea as exhibiting 
the development of the colourless spore-type, and 
Heterothecium Filot., emend., and Buellia, of the 
coloured.(*)
