2. S. ang-lica Kyi- Syn. i. (1860) p. 143, 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.

 Arr. i. p. 482. Lichen microceplialus Eng. Bot. t. 1865. In giving 

 the specific name of anglica, Nylander (I. c.) observes that the older 

 name microcepliala is not suitable to the apothecia. 



Differs from S. turbinata in the apparently (though very doubtfully) 

 proper thallus, hi 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 in situ, though I have observed a similar sterile thallus in many 

 places. The spermogones appear to be rare, and sparingly scattered, 

 with sperrnatia as in S. turbinata, or slightly larger. 



Hob. On old rails, especially oak, in shady situations in maritime and 

 upland tracts. Distr. Only sparingly in a few localities in S. and Central 

 England. B. M. : Caistor, near Yarmouth, Norfolk ; Ardingley and 

 Albourne, Sussex ; Twycross, Leicestershire. 



^ 3. S. microcephala Nyl. Mem. 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.

 cephnlum Tul. Mem. Lich. (1852) p. 78, t. 15. f. 20. 



Also closely allied to S. 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. 



Ilab. On the thallus of Fertusaria melaleuca in shady woods in mari- 

 time tracts. Distr. Onlv in the Channel Islands and the S. coast of
