2337. Pyrenula, A diminutive of irug»}», a kernel ; in allusion to the manner in which the receptacle is 
enclosed in the thalamium, as a kernel within its shell. Crustaceous plants, found chiefly upon the bark of 
trees. 
2338. Variolaria. The shields of these plants resemble the eruptive spots of the variolae or measles. The 
whole genus was referred by Linnceus to his Lichen fagineus and lacteus. The species are of a crustaceous 
nature, found upon the trunks of trees, rocks, wails, or the ground.
