Has. On rock, at Acho in Astore; above Burzil; and at ipee

Fertile in all the localities. Two specimens from Acho are mono-

the apothecia cover almost every particle of the upper surface, being 
rather darker than the normal form when they are dry; when 
moistened they become very livid, of various hues, flesh-coloured and 
purplish. The other specimens are fine and normal ; the apothecia are 
unchangeable by moisture, of a pale, but somewhat bright orange-red.
