BERKELEY AND CURTIS, EXOTIC FUNGI. 281 



24. ExciruLA APPLANATA, B. and C, applanata strigosaj disco palli Jo; sporis niiuutis oblongis brevibus 

 curvatis. Vermicularia applanata, Schwein. MSS. 



On bark ; Surinam. 



Cups small, flat, clothed with black rigid bristles ; disc pale, flat ; spores minute, 

 l-4000th of an inch long, oblong curved. 



Remarkable for its minute spores, which resemble those of a Cytispora, but in no 

 respect those of a Vermicularia. 



25. PucciNiA SOLANI, Schwein. MSS., hjpo-epiphyllum ; maculis nuUis; soris minutis distinctis compactis; 

 sporis pallidis parvis obovatis longe pedunculatis raro constrictis, nuclco conformi. 



On leaves of some species of Solanum ; Surinam. 



Sori minute distinct compact, occupying the whole of the under surface, and the 

 midrib only of the upper surface. Spores, with the long pellucid peduncle, l-830th 

 of an inch long, but very variable, obovate rarely constricted ; epispore thick ; 

 nucleus of the same shape as the endochrome. 



A very distinct and pretty species. 



26. P. cYNANCHi, Scbwein. MSS., hypophylla; maculis orbicularibus pallidis; soris minutis congestis; 

 sporis obliquis obtusis pallidis longe pedunculatis. 



On some species of Cynanchum ; Surinam. 



Hypophyllous ; spots pale, orbicular; sori minute, collected in the centre of the 

 spots ; spores oblique obtuse, short, pale, with a peduncle at least as long as 

 themselves. Very close to the next species, P. lateritia, but the spores are mostly 

 oblique, 



27. P. LATERITIA, B. and C., maculis pallidis orbicularibus ; soris depressis compactis parvis sub-confluenti- 

 bus; sporis obtu.sis brevibus medio leviter constrictis longe pedunculatis pallidis. Uredo lateritia, 

 Schwein. MSS. 



On the leaves, apparently, of some Spermacoce ; Surinam. This species has been 

 received from Alabama on Spermacoce glabra. 



Spots orbicular, pale ; sori numerous, flat, dark red brown, somewhat confluent 

 minute; spores obtuse, short, very slightly constricted, pale, with no remarkable 

 nucleus. 



DASYSPORA, B. & C. 



Sporae lato-oblongae medio constrictae uniseptatsc utrinque floccis brevibus exaspcratae vcl subpenicillatae. 

 Fungus liypophyllus sori/ormis ; peridio vero destitutus, inter Pucciniani Uredinemquc intermedins. 



28. Dasyspora FOVEOLATA, B. and C. Aecidium/oveolatum, Schyvem. 'MSS. 

 On living leaves; Surinam. 



Hypophyllous ; sori irregular, collected in little round patches, at first sight looking 

 like those of some Erineum, surrounded by the cuticle, but, as far as we have seen, 

 destitute of a proper peridium. Spores bright umber brown, l-500th of an inch long,
