130 CRYPTOGAMIA FUNGI. 



52. S. Hedera, scattered, black, minute, semi-immersed, promi- 

 nent, smooth, the centre depressed or concave and lighter colour- 

 ed. SPREN&. Syst. Veg. iv. 403. S. punctiformis y var. Hederce, 

 PERS. Syn. 90. HOOK. Scot. ii. 8. 



Hab. On dead ivy and oak leaves scattered over the whole 

 surface, rare. 



Though minute, this species is still considerably larger than 

 S. maculiformis or punctiformis, and readily distinguished 

 from both by its depressed and light centre. My speci- 

 mens are placed on the under surface of the ivy, and on 

 the upper surface of the oak leaves. 



53. S. empetri, capsules immersed, minute, black, distant, few 

 on a leaf, hemispherical, with an obscure papillary orifice. SPRENG. 

 Syst. iv. 403. 



Hab. On dead but still attached leaves of the crowberry. 



54. S. phaecomes, capsules immersed, minute, black, white with- 

 in, bearded with a pencil-like tuft of black rigid hairs. SPRENG. 

 Syst. iv. 404. Cryptosphceria capillata, GREV. Crypt. Fl. t. 69 ; Fl. 

 Edin. 362. 



Hab. Parasite on the dead leaves of grasses in woods, fre- 

 quent in this neighbourhood, and readily distinguished 

 by the minute little tufts which it forms on the leaves. 



55. S. trichella, capsules subimmersed, minute, scattered, black, 

 ovate, depressed, the summit covered with diverging rigid hairs 

 or bristles. Vermicularia trichella, GREV. Crypt. Fl. t. 345. 



Hab. On dead ivy leaves, occasionally. 



SPRENGEL makes this a variety of the preceding. I have 

 seen the same or a nearly allied species on decayed leaves 

 of Vaccinium Myrtittus. 



56. S. punctiformis, capsules scattered, punctiform, black, smooth, 

 globular, without a perceptible orifice. PERS. Syn. 90. HOOK. 

 Scot. ii. 8. 



Hab. On dead oak and sycamore leaves, in whiter, abun- 

 dant. 



The capsules are just visible with the naked eye. They are 

 very numerous, immersed in the cellular texture of the
