292 BERKELEY AND CURTIS, EXOTIC FUNGI. 



80. LembosIA ruytisjioides, n. sp., t-rumpcns ; peiitheciis flexucsis curvatis maculae inustae oibkulari 



insidentibus. Dothidea rhi/tismoides, Scbwcin., MSS. 



On the leaves of some palm ; probably from Surinam. 



Spots 2 — 3 lines or more broad, orbicular, pitch brown, with frequently a paler 

 border ; perithecia crowded, flexuous, intricate, depressed erumpent. 



We have not seen the fruit of this distinct species, which has, at first sight, the 

 appearance of a Rhytisma. 



*Strigula Banhsia, Schwein. MSS., is merely a diseased state of the tissue. 



*Excipula concentrica, Schwein. MSS., is certainly the work of some insect; Iho 

 black bodies contain scarlet sacs, such as occur in the eggs of Rhipignathus. 



*E. leguminum, Schwein. MSS., is apparently a Phonia, but we have not .seen 

 enough of the fructification to be quite certain. 



*E. arundinacea, Schwein. MSS., is clearly some Sphceria with immersed 

 perithecia and large ostiola. The specimens, however, are quite exoleto.

81. Capnodium fibrosum. Berk, in Hook. FI. Nov. Zell. Meliola palmae, Schwein. MSS. 



On leaves of some palm ; Surinam. 



*Erysiphe Surinamensis, Schwein. MSS. The specimens are too imperfect for 

 determination. On leaves of some shrub or tree ; Surinam. 



*Chatomiumbromeliae, Schwein. MSS. On leaves of bromelia ; Surinam. 



This is no ChcBtomium, but we are not prepared to say what it is. It has some 

 resemblance to an Epicoccum, but the structure is obscure. 



82. Meliola amphitricha, Fr. El. ii. p. 109. Melivla aterrima, M.piperum,M. tenuis, 31. Surinamensis 

 and M. diadelphas, Schwein. MSS. 



On various leaves ; Surinam. 



After a very careful investigation we find but one species, which is the more 

 surprising, as at least four species have been described, from Surinam. 



83. M. MUSiE, Mont. Ann. dc Sc. Nat. 2 ser. vol. xx. p. 375. Cladosporium orbiculana, Schwein. MSS. 



On leaves of pandanus ; Surinam. 



84. Hysterium rufulum, Fr. in Linn. vol. v. p. 552. H. patellariaemorphum, Sohwein. MSS. 

 On dead twigs; Surinam. 



The sporidia of the Surinam plant are oblong, obtuse, slightly curved or subcym- 

 biform, 1 -750th of an inch long. The specimens referred by Schweinitz in his 

 Synopsis to Patellaria nigrocinnaharma are the same thing. In the Pennsylvania 

 species, which also occurs in N. Zealand, we find them generally constricted at the 

 central septum and rather shorter, (l-830th,) though individual sporidia resemble 

 those of the Surinam plant. 



Diatrype stellulata, Fr., is on the same twigs with the present species. 



*iZ. sparsum, Schwein. MSS. On dead wood ; Surinam. The specimens are in 

 extremely bad condition, and without fruit. They resemble H. pulicare, to which 

 species we are at present inclined to refer them.
