Probably a stunted state; in size and general aspect like small condi- 
tions of R. fastigiata, but separated by the soredia. It is apparently 
always sterile.

no doubt to be detected elsewhere.—B. M.: Stowe Park, Buckingham-

Distinguished by the generally smaller size and especially by the smooth 
thallus. From 2. subfarinacea, which it closely resembles, it at once 
differs in the absence of any reaction with K on the medulla or the 
soredia. The apothecia are very rare, and in our specimens the spermo- 
gones are absent. 
Hab. On the branches of shrubs in maritime districts —Distr. Local 
and scarce in the Channel Islands, S.W. England, the W. Highlands of 
Scotland, and N.W. Iveland.—B. M.: Near Moulin Bay, Island of Sark. 
Near Penzance, Cornwall; Annet Island, Scilly (frt.). Black Island,

4, R. fraxinea Ach. Lich. Univ. (1810) p. 602.—Thallus sub- 
rigid, compressed, sublineari-laciniate, greenish-grey ; lacinize longi- 
tudinally rugose or nerved, or partly also transversely rugulose, 
somewhat attenuate towards the extremities (medulla K—). Apo- 
thecia pedicellate, moderate or large, carneo-testaceous or glaucous, 
concave or plane, marginal and superficial, the receptacle unequally 
rugose; spores oblong or oblongo-ellipsoid, curved, 0,011-16 mm. 
long, 0,005-7 mm. thick.—Hook. Fl. Scot. ii. p. 68; Sm. Eng. Fl.

The varied length and breadth of the laciniw give rise to several 
varieties and forms. The common and typical condition is that described 
(var. tenieformis Ach. Lich. Univ. p. 603). From R. calicaris it may be 
recognized by the always broader rugose lacinia, by the rugose receptacle
