290 BERKELEY AND CURTIS, EXOTIC FUNGL 



l-3d of an inch high, white papyraceous, clothed with a matted silky coat. Capilli- 

 tium containing a regular central subglobose cavity, the walls of which are perforated 

 with numerous pores. Threads radiating from the peridium straight, rather irregular. 

 Spores subglobose minute. 



A very curious genus, differing from every thing with which we are acquainted, 

 in its large regular central cavity. It is analogous to Broomeia, bm the mycelium 

 does not form a thick corky crust as in that genus, and it is allied to Lycoperdon 

 rather than Gea^^er. ,., ^, .. 



20. Sphaekopsis Huffeu, B. and C Perithcciis globosis demum liberatis, basi floccis brUriiieis cidctis ; 

 sporis oblongis hyalinis. Strigula ? Huffdi, Schwein. MSS. 



On the living stem of some Lobelia. West Indies. 



Perithecia globose obtuse, surrounded at the base with radiating threads; spores 

 hyaline oblong, often oblique, 1-1 500th of an inch long. 



21. S. SCRIPTA, B. and C, erumpens pulvinata subcarnosa nigra superfieie corrugata; peritheciis globosis; 

 sporis lato-oblongis hyalinis. Siphseria scripta, Schwein. MSS. 



On bark, bursting through the crust of various Lichens ; Surinam, 

 Pulvinate, about half a line across black slightly corrugated, black within ; 

 perithecia globose, with a short neck ; ostiola obsolete ; spores hyaline broadly oblong 

 l-1250th of an inch long, shortly pedicellate. 



Agreeing in general appearance with Hypoxylon corrugatum, but having the fruit 

 of a SphcBropsis. If the principle on which Spliceria has been divided were carried 

 out, this should form a distinct genus; but the real question is whether the genus 

 Spharopsis is truly distinct, or whether it comprises merely secondary forms of 

 Sphceria. 



22. S. SuRiNAMENSis, B. and C, sparsa nigra, peritheciis depresso-globosis ; sporis hyalinis elliptico- 



oblongis majoribus. 



On petioles of the leaves on which is Depazea Caladii ; not noticed by Schweinitz ; 

 Surinam. 



Perithecia depresso-globose, but projecting above the cuticle, opake, black. Spores 

 l-875th of an inch long, elliptico-oblong, broad, beautifully hyaline, 



23. Cytispora Palmicola, B. and C, nigra nitida, epidern.ide tectaj cellulis superfieie stromatis 

 nidulantibus globosis ; sporis- oblongis curvulis minutissimi.?. Sphaeria Palmicola, Schwein. MSS. 



On the outer husk of cocoanuts ; St. Kitts. 



Pustules orbicular about a line broad, covered by the cuticle; cells globose, seated 

 on the surface of the black stroma ; spores very minute, l-9000th of an inch long, 

 linear oblong, slightly curved. 



The specimens were referred by Schweinitz to Sphceria (Pertusae,) but in the 

 individuals before us we find a totally different structure.
