41. L. subintricata Th. Fr. Lich. Scand. p. 265 (1871).— 
Thallus very thin, finely granulose, pale-yellow or dull-greyish, 
or obsolete (K —). Apothecia small, plane then convex, variable 
in colour, yellowish, reddish-brown or dark-olive-brown, the 
thalline margin thin, entire, soon excluded ; paraphyses crowded 
and coherent, slender, branched, septate and scarcely wider 
upwards; spores ellipsoid, small, 5-10 » long, 3-4 w thick.—

Resembling L. intricata in the varying colour of the apothecia. 
Nylander considered this species to be very near to L. symmicta vay. 
sepincola, but with much smaller spores. Crombie gives as thalline 
reaction Kf + yellowish. I have been unable to verify this, but the 
thallus in the British specimens is very scanty. Crombie also gives 
*‘ spermatia thinly acicular, slightly arcuate, 6-7 » long, °5 pw thick.” 
Hab. On old palings in an upland district—B. M. Glen Fender,

42. L. sarcopisioides A. L. Sm.—Thallus effuse, thin, 
minutely granular, whitish-grey, often disappearing (K + yellow). 
Apothecia minute, numerous, sometimes aggregate, at first plane, 
becoming convex, reddish then dull-brown or blackish, sometimes 
slightly pruinose, the margin thin, quickly excluded ; paraphyses 
conglutinate, septate, capitate or scarcely widened upwards, often, 
dark over the apex, the epithecium and hymenium coloured dark- 
brown or blackish, often with a blue tinge ; spores oblong, 7-14 yu 
long, 3-4 p thick.—Z. metaboloides Nyl. in Flora lv. p. 250

A well-marked species, but easily mistaken for a Lecidea, as the 
thalline margin is only visible at an early stage. It differs from 
L. piniperda in the character of the thallus and in the colour of the 
hymenium. The spores vary considerably, but are usually elongate in 
our specimens as well as in those from Italy in our herbarium, though 
os the spore length as only 6 » x 24 (FI. Ital. Crypt. iii. 
if Nylander quoted as synonymous with his species (L. metaboloides) 
the one published earlier by Massalongo as Biatora sarcopisioides, 
and cites as typical Anzi Exs. Lich. rar. Venet. n. 61, a specimen 
with a more evident thallus, probably due to the weathered wood on 
which it grows. Another specimen, Anzi Exs. Minus rar. Ital. n. 175,
