usually rather small, about 3-5 cm. in diameter to 10 cm. or 
more, submonophyllous, often several lobes from one centre, 
somewhat rigid, smoothish or somewhat wrinkled, light or dark- 
brown, the lobes broadening outwards, rounded, usually thickly 
sprinkled with dark-brown coralloid isidia, beneath pale-brown, 
tomentose, with whitish or pale cyphelle. Apothecia small,

with a crenate thalline margin; spores fusiform, colourless, 
1—3-septate, 27-40 » long, 7-8 p» thick.—S. F. Gray Nat. Arr. i.

An easily distinguished species from the dull-brown colour and 
the sprinkling of still darker isidia. These evidently function as the 
principal organs of propagation, apothecia being very rare.
