2. S. anglica Nyl. Syn. i. (1860) p. 148, t. v. f. 3—Thallus (if 
proper) effuse, thin, granuloso-unequal, greyish-brown or olive- 
green, or evanescent. Apothecia small, scattered, substipitate, 
globose or globoso-turbinate; spores simple, globose, sometimes 
ellipsoid or oblong, 0,008-13 mm. long, 0,006-9 mm. thick; 
hymenial gelatine bluish with iodine ——Mudd, Man. p. 255; Cromb. 
Lich. Brit. p. 11; Leight. Lich. Fl. p. 38, ed. 3, p. 38.— Calicium 
microcephalum Turn. & Borr. Lich. Br. p. 180; Sm. Eng. Fl. v. 
p. 188. Phacotium (errore Phacotrum) microcephalum Gray, Nat. 
Arr. i. p. 482. Lichen microcephalus Eng. Bot. t. 1865.—In giving 
the specific name of anglica, Nylander (1. ¢.) observes that the older 
name microcephala is not suitable to the apothecia. 
Differs from S. turdinata in the apparently (though very doubtfully) 
proper thallus, in the more stipitate apothecia, and the larger spores. In 
the original specimen figured in E. B., the thallus is partly subtartareo- 
granulose and partly subevanescent; but I have never seen the fertile 
plant z situ, though I have observed a similar sterile thallus in many 
places. The spermogones appear to be rare, and sparingly scattered, 
with spermatia as in S. turdinata, or slightly larger. 
Hab. On old rails, especially oak, in shady situations in maritime and 
upland tracts.—Dvst. Only sparingly in a few localities in S. and Central 
ngland.—B. M.: Caistor, near Yarmouth, Norfolk; Ardingley and 
Albourne, Sussex ; Twycross, Leicestershire. 
3. S. microcephala Nyl. Mém. Soc. Cherb. v. (1857) p. 91.— 
Thallus none. Apothecia minute, sessile or substipitate, globose 
or globoso-turbinate; spores simple, fusiformi-ellipsoid, somewhat 
large, 0,011-16 mm. long, 0,007-8 mm. thick ; hymenial gelatine 
faintly bluish with iodine.—Nyl. Syn. i. p. 144, t. v. f. 2; Cromb. 
Lich. Brit. p. 11; Leight. Lich. Fl. p.39, ed. 3, p.38.—Sphinctrina 
turbinata (3. microcephala Mudd, Man. p. 256. Calicium micro- 
cephalum Tul. Mem. Lich. (1852) p. 78, t. 15. f. 20. 
Also closely allied to 8. turbinata, but may readily be distinguished on 
microscopical examination by the form and size of the spores. In our 
British specimens the apothecia, which are smaller than in the preceding 
species, are usually rather scattered, as are also the spermogones. 
_ Hab. On the thallus of Pertusaria melaleuca in shady woods in mari- 
time tracts.—Distr. Only in the Channel Islands and the S. coast of
