194. S. (Depazea) concava, n. s. Maculis subrotundis, ex- 

 cavatis, cervinis, margine fusco ; peritheciis subcentralibus, 

 tenerrimis, fuscellis, ostiolo brevissimo, ore rotundo ; gelatina 

 subcirrhosa; sporis oblongis, uniseptatis, medio contractis. 

 On pods of the garden pea, and occasionally on the leaves 

 and petals. King's Cliffe. It was also pointed out to me by 

 Captain Carmichael at Appin in 1824. 



Very destructive in damp seasons to peas, in the pods of 

 which it forms little round fawn-coloured pits studded in the 

 centre with the short subcirrhiform masses of the spores. The 

 plant is just the same on the leaves, except that in conse- 

 quence of their less succulent nature the depression is not so 

 evident. On the petals there are no spots, but merely scat- 

 tered perithecia, especially upon the veins. Perithecia very 

 delicate, but certainly present. Spores oblong, contracted in 

 the middle, uniseptate, with occasionally a single nucleus in 

 each cell. Other forms, arising from the total or partial sup- 

 pression or elongation of one of the cells, will be seen in the 

 figure.

 nified. 



195. S. (Depazea) Convolvulicola, Dec, Fl. Fr. 6. p. 148. 

 On Convolvulus arvensis. King's Cliffe. This species has 

 been communicated to correspondents under the name of S. 

 fuscella, n. s. 



*196. Sphceronema blepharistoma, Berk, in Mag. of Zool. 

 and Bot. vol. i. p. 512. Sphceronema vitreum, Corda, 1c. Fasc. 

 l.f. 297. 



There is no doubt that my plant and that of Corda are 

 the same, though their habitats are so very different. I find 

 it, however, not only on decayed Ag. adustus, but also on 

 nettle roots. I do not know which name has the priority, mine 

 or Corda's. But as the preface of M. Corda's Fasciculus is 

 dated Aug. 1836, although not published till 1837, in which 

 year also my paper appeared, it will be better at once to adopt 

 Corda's name, especially as it is very descriptive. 



197. Phoma concentricum, Desm. ! ined. Depazea Agaves, 

 Mont. Ann. des Sc. Nat. n. s. 1. p. 344. Common on leaves 

 of Yucca, This plant has been communicated to correspond- 

 ents under the name of P. circinans. I have, however, spe- 

 cimens from M. Desmazieres under the name adopted above, 

 and under which it is possibly already published*. It is a true
