286 BERKELEY AND CURTIS, EXOTIC FUNGI. 



About an inch long, half as much across, black pulvinate, with a thin margin, 

 brown within ; perithecia elongated ; ostiola short, elevating the surface into little 

 papillseform strongly umbilicate dots. 



Distino-uished from H. microstictum by its smooth not granulated surface ; from H. 

 nummularia, some forms of which it greatly resembles, by its oblong closely packed 

 perithecia. 



55. H. SCLEROTIOIDEUM, n. sp., pulvinatum Igeve Yinosum; intus concolor; peritheciis oblongis stipatis, 

 ostiolis obsoletis. Spliseria sderotioidca, Schwein. MSS. 



On stringy bark ; Surinam. 



Pulvinate even, two lines broad, nearly a line thick, rubigino-vinous externally ; 

 stroma of the same color. Perithecia oblong, crowded, reaching nearly to the base 

 of the stroma ; ostiola obsolete. 



A very distinct species, remarkable for its even surface, which gives it the 

 appearance of a Sclerotium. 



56. H. SOLIDUM, B. and C, orbiculare, lobatum, irregulare rubiginosum ex ostiolis minute punctato- 

 papillatmm; intus subconcolor; margine libero; perithcciis oblongis minutis, gelatin a rubida farctis. 

 Rhi/tisma solidum, Schwein. MSS. 



On mossy bark ; Surinam. 



About an inch broad, orbicular lobed, rather irregular, red-brown, here and there 

 rubiginous, minutely punctato-papillate from the ostiole, margin free, rather obtuse ; 

 substance nearly of the same color, firm, spongy below. Perithecia minute, oblono-, 

 filled with a reddish jelly. Fructification immature. 



57. H. scLEROPHL.ffiUM, B. and C, irregulare suborbiculare intus atrum, extus atro-purpureum, papillatum 

 papillis pertusis; peritheciis oblongis brevibus. Sphaeria durissima, Schwein. MSS. 



On bark ; Surinam. 



About three-quarters of an inch across, one line thick, suborbicular, irregular, 

 uneven, black within, externally purple brown or vinous, covered with minute 

 papillae, which are strongly perforated in the centre. Perithecia oblong, rather 

 crowded, short, occupying only a portion of the stroma. 



Resembling somewhat H. hamatostroma, Mont., but far less strongly papillate, with 

 shorter perithecia and a black stroma. H. vinosum has a yellowish stroma. The 

 open mouths of the perithecia are very remarkable. 



58. H. BiPAPiLLATUM, B. and C, effasum connatum nitidum ; peritheciis globosis sursum proniinulis • 

 ostiolo papillffiformi. Sphaeria colliculosa, Schwein. Herb, quoad specimina Surinamensia, sed non 

 Syn. Fung. 



On dead wood ; Surinam. 



Effused, black, shining, thin ; whitish within; perithecia globose, raising the stroma 

 above into large papillae, with a little raised ostiolum in the centre of each minutely 

 truncate elevation. 



Allied to E. lucidum, Mont., but not so shining, nor are the elevations of the stroma 

 so large.
