Phacotrum (Phacotium) cantherellum 8. F. Gray Nat. Arr. i. 
p. 484 (1821).

in the apothecia, which are very pale yellow, often with a tinge of 
cinnamon on the upper side of the capitulum.

—Distr. Very rare in Central and N. England, probably over- 
looked elsewhere.—B. M. Mundon, Essex; Teesdale, Durham ; near 
Hexham, Northumberland. 
4. C. hyalinella Nyl. in Act. Soc. Linn. Bord. sér. 3, i. 
p. 279 (1856-8).—Thallus obsolete. Apothecia small; stalk 
slender, whitish, brownish above ; capitulum globose, the sporal 
mass white or pale-reddish ; spores minute, 2° 5—4 in diameter.— 
Cromb. Lich. Brit. p. 14; Leight. Lich. Fl. p. 47; ed. 3, p. 46. 
Closely allied to C. pallida, but differing in the smaller apothecia 
and spores. Occasionally there are doubtful traces of a thin whitish 
thallus. 
Hab. On decayed trunks of trees—B. M. Brantsdale, Yorkshire.

Thallus thin, granular or pulverulent, rarely squamulose, 
sometimes obsolete or none proper. Apothecia stalked, the 
capitulum top-shaped or subglobose, blackish-brown, often finely 
powdered with a white, yellow or reddish pruina; paraphyses 
slender; spores elongate or ovate, l-septate, dark-coloured. 
Spermogones similar to those of Cheenotheca. 
Similar in outward appearance to Chenotheca, differing chiefly in 
the spore characters. Some of the species have been classified by 
Continental botanists as fungi. 
Capitulum yellow-pruinose. 
1. C. arenarium Nyl. ex Lamy in Bull. Soc. Bot. Fr. xxv. 
p. 345 (1878).—Thallus none proper. Apothecia congregate or 
scattered, rather small, the stalk stoutish, elongate, rusty-brown, 
sometimes with a yellowish pruina ; capitulum globose-lentiform ; 
spores oblong, becoming 1-septate, rarely with a slight constric- 
tion in the middle, pale-brown, 6-11 pw long, 2°5-3°5 yp thick, 
paraphyses slender, scanty.—Cromb. in Grevillea xv. p. 14 (1886).
