BERKELEY AND CURTIS, EXOTIC FUNGI. 2i)l 



77. S. iNA.vis, Scliwcin. J!SS., li}po},li3lla spnrsa tecta, pciitlicciis dcpresso-gUibosis npIcibuB suniinis 

 epida-inide aJnatis, dcraum cuiu epidcrmidis particula cci-.tro circunucissis ; asiis oUongis; sporidiis 

 oblongo-linearibus curvis. 



On the underside of the leaves of some aroid ; Surinam. 



Purithecia scattered, depressed, subglobose, adnate by a small portion of the 

 summit with the cuticle, which consequently exhibits a black dot ; at length splitting 

 in the centre and falling oft', together with a speck of the cuticle. Asci oblon<^ ; 

 sporidia hyaline, linear-oblong, about 1-lOOOth of an inch long, curved. 



*5'. curassavicce, Schwein. MSS. On living stems of Asclepias curassavica from 

 Hiiffel's Indian Mission. The specimens have, unfortunately, not perfected their 

 fruit. 



*S. hromeliue, Schwein. MSS. On bromelia; Surinam. Somewhat resembling 

 such species as S. pardalota. The specimens exhibit no trace of fruit, and we cannot 

 therefore say anything of its affinities. 



*S. wi/rr/a, Schwein. MSS. On twigs; Surinam. Probably a Z)/j9/od/?«, but all 

 fructification has vanished. 



*S. epidendri, Schwein. MSS, On some orchid; Surinam. Doubtful in 

 consequence of the absence of fruit. The perithecia, which look like those of a 

 Leptostroma, are dark blue when seen by transmitted light. 



S. ramulosa, Schwein. MSS. On dead wood ; Surinam. This is some very 

 distinct Xylaria or Thamnomyces, but the specimens are in such a condition that we 

 can come to no decision respecting them. 



T8. Depazea caladii, Schwein. MSS., maculis latis aniiulari-multicoloribus ccntro pallidis; perithcciis 

 congestis ; asois brevibus ; sporidiis hyalinis oblongis medio uniseptatjs.. 



On the leaves of some caladium ; Surinam. 



Spots one-third of an inch or more across, consisting of three orfour rings, varying 

 from pale olive to pale umber; perithecia minute, crowded. Asci short; sporidia 

 hyaline, oblong, l-2500th of an inch long, very slightly curved, with a single septum 

 in the centre. 



It is almost certain that the phyllostictous Septoiice are mere states of true Depazere, 

 of which the asciferous form is rarely produced. 



*D. argentea, Schwein. MSS., has no perithecia, and therefore cannot be admitted 

 as a species. 



79. AsTERiNA AsrjRATA, n. sp., maculis orbicularibus tenuissimis ; perithcciis minutisbiinis punctiformilus 

 aspcratis. Dothidea asjierata, Schwein. MSS. 



On living leaves; Surinam. 



Spots 2—3 lines broad, orbicular, at first distinct then confluent ; subiculum very 

 thin, densely intcrvvoven, sprinkled with very minute punctiform perithecia. 



Unfortunately we can find no fruit in the specimens before us. The specie-s has 

 very much the appearance of Singula Babtngto?ni, Berk. It has, however, much 

 fimaller perithecia and a less lichenoid habit-
