Readily identified by the neat white pustules and by the habitat 
on trees, very rarely on rocks, and then to be distinguished from 
P. lactea by the absence of reaction with calcium hypochlorite. 
There is a faint yellow reaction with potash which passes at once to 
reddish-brown or sometimes red, especially the medulla. 
Hab. On trunks and branches of trees, rarely on schistose rocks, 
in maritime and inland districts.— Distr. Fairly common in England 
and Wales, less so in Scotland and Iveland.—B. M. Boconnoc, Corn-

Form levigata Cromb. Monogr. i. p. 495 (1894).—Thallus 
thin, almost continuous and scarcely wrinkled.—Variolaria 
multipuncta var. levigata Turn. & Borr. ex Hook. in Sm. Engl. 
Fl. v. p. 170 (1833) & Lich. Brit. p. 73 (1839). V. constellata 
Tayl. in Mackay Fl. Hib. ii. p. 113 (1836). 
A thinner less developed thallus and apothecia than in the species, 
possibly due to the habitat on smooth bark. 
Hab. On smooth bark of young trees.—Dvistr. Found only in a 
few localities in S. England and 8.W. Ireland.—B. M. Falmouth, 
Cornwall; New Forest, Hants; St. Leonard’s Forest, Hants; Askew 
Wood, Kerry. 
Form fastigiata Cromb. ]. c.—Thallus of crowded coralloid 
fertile verruce, fastigiate and sorediate at the apices.—P. fas-

var. 8 Hook. in Sm. Engl. Fl. v. p. 232. Variolaria polythecia 
Tayl. in Mackay Fl. Hib. ii. p. 113 (1836). 
A well marked form. Dr. Taylor (1. c.) describes it as conspicuous 
by the crowded and stalked apothecia placed in contact, like certain 
basaltic columns.

regions.— Dist, Recorded only from §. and W. Ireland (Bantry, Cork ; 
Connemara, Galway).—B. M, Dunkerron, Kerry.
