IX. On some New Zealcmd Verrucariae. By Charles KxreHT, Esq., F.L.S. 
Read February 16th, 1860. 
THE following paper contains a description of certain corticolous Lichens of New 
Zealand, accompanied by figures of the spores. 
The size of the spores of the same Lichen is found to vary within certain limits. 
Those contained in the ascus are frequently much smaller than some of the loose spores 
found solitary on the field of the microscope. Spores of a brown colour when mature, are 
of a lighter colour, or even diaphanous, when young. The septa are not always visible 
until after the spores are perfectly mature ; frequently the number of the septa is fewer in 
the young spore.
