BERKELEY AND CURTIS, EXOTIC FUNGI. 289 



quantity of short clavate articulate threads. There are no perithecia or cells, there- 

 fore it is impossible to say to what genus it belongs; possibly to an Asterina. 



*D. indistincta, Schwein. MSS. On leaves; Surinam. This, also, has somewhat 

 the appearance of an Asterina, but is probably a true Dothidea. The spots scarcely 

 exceed a line in breadth, and are of a dull black, superficial, of a friable substance, 

 studded with minute projecting cells. We have not been able to detect any fruit, 

 and therefore leave the species doubtful. 



*D. e>«e.i7j/«crt^a, Schwein. MSS. On leaves; Surinam. We find only diseased 

 cellular tissue. 



*D. hypophylla, Schwein. MSS. On the upper surface of the leaves of some 

 melastomad, not on the under as the name implies. It is evidently an Asterina, but 

 the specimens are incomplete. 



*D. Horsfieldii, Schwein. MSS. On leaves ; Java. Dr. Horsfield. 



It is very doubtful whether this is a fungus. The spots are, we believe, due only 

 to a diseased state of the parenchyma. 



*D. aroidarum, Schwein. MSS. On the upper surface of the same leaves which 

 produce Sphceria inanis- If a true species, of which there is some doubt, the 

 specimens are immature. 



CORALLOMYCES, B. and C. 



Stroma ramosum filiforme palmatumque laste coloratum; perithecia nuda ramis insita concoloria; sporidia 

 hyalina. Genus Cenocarpi, Fr. analogon. 



71. C. ELEGANS, B. and C. SpTiaeria pseudovillosa,^(i\i'viein. MSS. 

 On bark ; Surinam. 



Forming little pulvinate tufts, consisting of variously branched cylindrical and 

 palmate processes of a dark cinnabar red, towards the apices of which are seated, 

 singly or in whorls, naked sublagenseform, perithecia of the same color; asci filiform, 

 containing a single row of elliptic uniseptate hyaline sporidia, l-1750th of an inch, or 

 more, long. 



This very curious production is to Ncctria what Cenocarpus (C. hippotrichoides) is 

 to Sphceria. The individual perithecia are an exaggerated form of iVec/na sa/zj/wmea. 



72. Nectria pseudotriciiia, n. sp., subcespitosa ; peritheciis globosis rubris, ostiolo minuto papillajformi, 



demum collapsis ; sporidiis majoribus latis elliptico-oblongis cellulosis. Sphaeria pseudotrichia, 

 SchweiD. MbS. 

 On bark ; Surinam. 



Subcespitose; red, inclining to vermilion, globose, smooth, with a minute 

 papillseform ostiolum, at length collapsed and pezizaeform. Asci at first sublanceolate, 

 then irregular. Sporidia large, variable, elliptic-oblong, l-664th of an inch long, 

 one-third or one-fourth as much broad, cellular.
