NiDULARIA. 



JV. striata, Bull, var. pusilla, Berk. Smaller, only ^ an 

 inch high. Furfuraceous above. Striae confined to the mar- 

 gin. Colour dull umber, not bright brown. Very near to 

 N, plicata, Fr., a Brazilian species. That however appears 

 to be even more strongly grooved than N. striata. 



West Indies. 



SPHiERIA. 



1. B. [Cordyceps) digitata, Fr. Negapatam. Dr. Wight. 



2. S. [Cordyceps) allantodia, Berk. Corky; stem ex- 

 tremely short, almost obsolete, smooth ; stroma clavate, ob- 

 tuse, thick, coated with a thick rigid brown-black bark ; pe- 

 rithecia small, globose ; ostiola minute, prominent ; about 4 

 inches high, 1 inch thick, attenuated below, often curved, at 

 first solid throughout, with the inner substance firm and pale 

 brown, at length more or less hollow, resembling closely a 

 small black-pudding. Some specimens are more elongated 

 and thinner. Outer coat black, w^ith a brown bloom like that 

 of some exotic Polypori, very hard and rigid, distinct from the 

 substance, in old plants sometimes contracted. Perithecia 

 small, crowded. Ostiola minute, rather prominent. 



Brazil. 



3. S. {Cordyceps) Telfairii, Berk. Corky, club-shaped, more 

 or less obtuse above, clothed with very brittle fawn-coloured 

 bark dotted with the black orifices of the rather large peri- 

 thecia. About 2 J inches high, J an inch thick ; solid ; bark 

 extremely brittle, black coated with a thin distinct fawn-co- 

 loured coat, apt to become involute. Perithecia rather large, 

 subglobose. Ostiola black, slightly prominent. Asci long, 

 linear, slender, containing eight segmentiform sporidia, which 

 occasionally contain a single central sporidiolum. 



Mauritius. Mr. Telfair. This is marked by Klotzsch S. 

 involuta, spec. nov. I have thought it best not to adopt the 

 manuscript name, as the bark in other allied species is often 

 involute. 



4. S. {Cordyceps) obovata, Berk. Stem short, smooth, gra- 

 dually swelling out into a short obovate club, hollow, lined 

 with a papyraceous coat ; bark black ; perithecia rather large, 

 scattered -, ostiola very minute. Whole plant not | of an inch
