bington, who proposes to substitute for the specific name 
“conferta” that of “ mesiota,” as there is another species in 
the‘ Systema Mycologicum’ previously published by Schweinitz 
with the same name. 
178. S. (Conferte) Rhytismoides, Bab. in Abstr. Linn. 
Trans. p. 32. Peritheciis tenuissimis globosis, sparsis 1. con- 
fertis, epidermide nigrefacta polita tectis ; gelatina salmoneo- 
rubra farctis, ostiolo minimo obsoleto. On leaves of Dryas 
octopetala, Inchnadamff, Assint, Sutherlandshire. Mr. 
Churchill Babington, Sept. 1838. 
Epiphyllous, occupying the whole surface or detached por- 
tions of the leaf. Perithecia generally scattered, sometimes 
confluent ; in the former case the epidermis between them is 
cinereous, but that part immediately lying above them, where 
it is raised into a little hemispherical dot, jet-black and shining, 
from a thin carbonaceous layer situated immediately beneath 
the cuticle. Perithecia extremely thin, transparent, membra- 
nous, dotted with raised salmon-coloured areole; ostiolum 
simple, very minute. Contents of perithecia salmon-coloured, 
containing clavate asci with linear paraphyses. Sporidia bi- 
seriate, oblong, obtuse, sometimes containing two sporidiola. 
The species does not appear to be very nearly allied to any 
hitherto described ; its most obvious affinities, however, are 
with Conferte. ‘

*179. S. ceuthosporoides, Berk. in Eng. FI. vol. v. part 2. 
p- 258. Mr. C. Babington finds this little-known species at 
Coleorton, Leic. 
*180. S. aquila, Fr. Syst. Mye. vol. ii. p. 442. In conse- 
quence of the inspection of some incorrectly named specimens, 
I have been led into error about the plant named S. dbyssiseda, 
Fr., in the English Flora, which is undoubtedly S. aquila, Fr. 
(S. byssiseda, Kz.), and that named S. agquila, Fr. is S. thelena. 
S. aquila is not very uncommon at the bottom of stakes, and 
sometimes occurs on sticks and trunks of trees. S. thelena 
is far more uncommon, and has hitherto been found only by 
Capt. Carmichael. 
*181. S. tristis, Tode. Fr. Syst. Myc. vol. ii. p. 444. Since 
the publication of Eng. FI. I have met with the collapsed form 
of this species. 
182. S. fulva, Fr. El. 2. p. 90. On box leaves, Milton, 
Norths., Mr. J. Henderson. Two forms occur, one of a dull 
straw colour, the other of a brick red.
