On the Lichen-Flora of Epping Forest, 
Formerly on trees at High Beach (J. M. C.). Not observed 
by me recently. 
L. orosthea, var. sublivens, Nyl. — On the trunks of old 
trees, near the roots, beyond the “King’s Oak,” High Beach 
(J. M. C.). This unusual variety, distinguished from Biatora 
straminea, Stenh., by the livid colour of the apothecia, was 
for the first time gathered in the above locality, whence it is 
now extinct in consequence of the trees being felled. 
L. comziEA, Ach. — On old pales at The Warren and Copt- 
hall. Not uncommon, but rarely fertile (J. M. C.). The 
sterile thallus is also frequent on pales elsewhere. 
L. coniz^eoides, Nyl. — On exposed roots of old beeches in 
Great Monk’s Wood and at High Beach. Plentiful, but often 
sterile (J. M. C.). This species was for the first time collected 
in the above localities, but has since been found elsewhere in 
S. and W. England. 
L. parella, f. turnida, Pers. — On Epping Forest ( Hb. 
E. F.). Near High Beach (J. M. C.). I have not recently 
observed this species. 
Yar. turneri, Sm. — On the Forest, near King’s Oak (Hb. 
E. F.). On an old tree at High Beach (J. M. 0.). This 
seems to be now extinct. 
L. cinerea, L. — On a tombstone in Walthamstow Church¬ 
yard (E. F.), vide Forster’s notes, s. n. Urceolaria cinerea. Of 
this there is no specimen preserved in his herbarium, and 
it is scarcely likely to be the true plant. 
Tribe— Pertusariei. 
Pertusaria communis, DC. — On the Forest (Hb. E. F.). 
Frequent about High Beach, and here and there elsewhere 
(J. M. C.). 
P. globulifera, T. & B. — On the Forest, near King’s Oak 
(Hb. E. F.). At High Beach (J. M. C.). This species does 
not occur in its typical state, but only in the form discoidea of 
authors. 
P. amara, Ach.—On Hainault Forest. Sterile (Hb. E. F.). 
Fairmead Woods, and sparingly in other parts of the Forest 
(J. M. C.).
