The minute pale dots on the crust of the thallus are 

 small protuberances, or elevated excrescences.* The large 

 ultimate spores, one in each of the cells of the sporidium, 

 give a very singular appearance to them, peculiar to this 

 species, and unmistakeable. 



/3. DERMATODES. Sporidia in asci 8, precisely similar 

 in shape, colour, division, and appearance to those 

 of F". nitida, though only about half the size. Plate 

 XV. fig. 4.

Specimens described in E. Bot. Suppl., in herb. 

 Borrer ! 



The perithecium is very distinctly figured in E. Bot. 

 Suppl., as being deficient at the base ; but my examina- 

 tion of the specimens used for that work has convinced 

 me that there must be some mistake ; for I find the peri- 

 thecium to be perfectly entire, and to subtend the base 

 of the nucleus, precisely as in 7iitida. The nucleus in 

 both plants is brown in a dry state, whitish and hyaline 

 when moistened. The sporidia prevent this from ever 

 being confounded with any state of V, epidermidis, or 

 V, cinerea. 



Examination of Mr. Borrer's specimens (on Holly, 

 Askew Wood, Ireland ! Br. Taylor) proved that the 

 Verrucaria represented in E. Bot. Suppl. 2607. ^g. 2 b, 



* These, Mr. Borrer (mlit. 1850) says, "I always find present on British 

 specimens, but not on the morsels that I have seen from Acharius." They 

 did not exist on an abundant collection of the species which Mr. Spruce 

 made in the Pyrenees.
