Perhaps more of a variety or form than a subspecies. It is 
frequently much branched above, but distinguished chiefly by the 
deeply and elegantly divided squamules, which tend to become hooded 
at the apices. Wainio has associated with the above C. Lamarkw 
f. Istgnyz Nyl., included here under C. pityrea f. hololepis. 
Hab. On mossy boulders and decaying trunks of trees in wooded 
districts.— Distr. Rare in W. and N. England, N. Wales, S. and W. 
Scotland and N.W. Ireland.—B. M. Withiel, Cornwall; Balcombe, 
Sussex; Aberdovey and Dolgelly, Merioneth; Ingleby and near 
Battersby, Cleveland, Yorkshire; Tongland, Kirkcudbrightshire; Appin 
and Barcaldine, Argyll; Loch Linnhe, Invernessshire; Leenane, near 
Kylemore, Galway. 
30. C. subsquamosa Nyl. ex Cromb. in Journ. Linn. Soc. 
xvii. p. 560 (1880) & Monogr. i. p. 158.—Primary thallus of 
small crenate squamules, pale or greyish-green above, white below ; 
podetia usually rather short, branched, with or without scyphi, 
with axils and scyphi pervious, squamulose below, almost decor- 
ticate, granular upwards, furcate or radiate-cristate, the branches 
subcorymbose at the apices (K + yellow, then crimson, CaCl —). 
Apothecia small, solitary or aggregate, reddish-brown ; spores 
oblong or fusiform-oblong, 8—12 » long, 2° 5-3 pw thick.—C. delicata 
var. subsquamosa Nyl. ex Leight. in Ann. Mag. Nat. Hist. ser. 3, 
xviil. p. 407 (1866) ; Cromb. Lich. Brit. p. 20; Leight. Lich. FI. 
p. 59; ed. 3, p. 55.

Differs from the preceding chiefly in the reaction with potash, a 
swift vivid yellow changing after an interval to a dullish crimson. It 
is like C. sqwamosa, a very variable plant, no two specimens being 
exactly alike. A number of forms characterized by some peculiarity 
of growth have been published by J. Stirton (Scott. Nat. ix. p. 119 
(1885) ). These are ff. delatata, swblactea, defleca and compressula. 
which I have not seen, and ff. furfurosa, phyclina, cristata and 
sptlota, specimens of which have been loaned by J. M‘Andrew. 
Hab. On decaying stumps of trees and on mossy soil in maritime 
ard inland districts. —Distr. Widely distributed, though not common, 
throughout the British Isles.—B. M. Noirmont Bay, Jersey; near 
Penzance, Cornwall; Bolt Head, Devon; Shanklin, I. of Wight; 
Eridge rocks, Sussex ; Ightham Common, Kent; Hay Coppice, Here- 
fordshire; Barmouth, Merioneth; Kildale and Ingleby, Cleveland, 
Yorkshire ; Alston, Cumberland; Bellingham Woods, Northumber-
