290 BERKELEY AND CURTIS, EXOTIC FUNGI. 



Differing from all lis allies ia its curious sporidia, which resemljle somewliat those 

 of Spharia kerharum. The sporidia of N. polythalmna, Mont., are septate, but 

 shorter and narrower, and scarcely cellulose. 



*Tubercularia Smilacu-, Schwein. MSS. From Surinam. Appears to be a 

 Nectria, but there is no fructification in the specimens before us, which are very 

 imperfect. 



73. SpiIyEria tornata, B. and C, sparsa; peritheeiis magnis basi cpiderniiJe .stcll.ita cinctis raamma;- 

 formihus opacis conccntrice lincatis, ostiolo papillasfoimi, <S. stelluhtta, Schwein. MSS. 



On the leaf, apparently, of some palm ; Surinam. 



Scattered, perithecia as large as a grain of mustard seed, surrounded at the base 

 by the thick stellate cuticle, mammseform opake, marked here and there with 

 concentric rings, as if turned in a lathe, terminated by a minute papilla. There is 

 no crust, and the species, though resembling some Verrucaria, is clearly a SphcBria. 

 Unfortunately the perithecia contain no fruit. 



7-4. S. mapanIjE, Schwein. MSS., cfespitosa, apicibus spicarura congcsta; peritheeiis ovatis suvsum 

 attenuatis, ostiolo papillceformi, sporidiis oblongis subquadriseptatis curvulis. 



On the tips of the spikelets of mapania ; Surinam. 



Black, or, when seen by transmitted light, tinged with purple, caespito.se, collected 

 at the tips of the spikelets. Perithecia ovate, attenuated upwards. Ostiolum 

 papillaeform. Asci clavate. Sporidia lineari-oblong, hyaline, subquadriseptate, l-750th 

 of an inch long, but very variable 



The habit is very much ttiat of Conjnelia. The species is allied to S. pulicaris 

 and 5', Sauhinetii. 



75. S. RUBROOiNOTA, Schwein. MSS., subteota, peritheeiis subglobosis pruino.sis ostiolo hrevissimo pulvcro 

 aurantiaco cincto, pporidiis breviter oblongis curvulis. 



On bark ; Surinam. 

 . Perithecia subcuticular, globose, pruinose, pale, tinged with reddish brown obtuse; 

 ostiolum very short, surrounded by an orange-colored pulverulent halo, consisting of 

 amorphous particles. Sporidia oblong, slightly curved, l-4000th of an inch long, 

 with tw^o or three nuclei. 



76. S. COMEDENS, Schwein. MSS., hypophylla, peritheeiis subcongestis proniinulis epidermide tcctia 

 subastomis ; asois brevibusobtusis; sporidiis elongatis subclavatis. 



On dead leaves; Surinam. 

 ^ Forming little patches consisting of gregarious but not confluent rather prominent 

 perithecia. Asci short, clavate, obtuse; sporidia elongated, subclavateand, apparently, 

 when mature, furnished with a septum at the narrow end. 



On the same leaf is another production, exhibiting crowded minute orbicular 

 brownish specks, crowded with perithecia, but without fruit. It is doubtful, 

 therefore, which of the two was intended by Schweinitz. We have, however, tliought 

 it best to take that which is most perfect.
