bington, who proposes to substitute for the specific name 

 * conferta" that of is mesiota," as there is another species in 

 the f Sy sterna Mycologicum' previously published by Schweinitz 

 with the same name. 



178. S. (Confertce) 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 

 ociopetala, 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 areolae ; 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, how r ever, are 

 with Confertce.

 11, portion of the delicate perithecium ; 12, ditto more highly magnified; 

 13, 14, asci and paraphyses; 15, sporidia. 



*179. S. ceuthosporoides, Berk, in Eng. Fl. vol. v. part 2. 

 p. 258. Mr. C. Babington finds this little-known species at 

 Coleorton, Leic. 



*180. S. aquila, Fr. Syst. Myc. 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. byssiseda, 

 Fr., in the English Flora, which is undoubtedly S. aquila, Fr. 

 (S. byssiseda, Kz.), and that named S. aquila, Fr. is S. thelcena. 

 S. aquila is not very uncommon at the bottom of stakes, and 

 sometimes occurs on sticks and trunks of trees. S. thelcena 

 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. Fl. 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.
