HYPOCRELLA AND ASCHERSONIA. 205 



The type specimen in, Herb. Kew is labelled " Hypocrea 

 palmse. Ttcbercularia palmce Schwein. Surinam. Herb. Schwein."; 

 it contains two specimens, 2 and 4 mm. in diameter respectively 

 now detached from the leaf ; they are now black, about two-thirds 

 globose, and ridged obliquely ; Berkeley gave the colour as red- 

 brown ; the surface is irregularly wrinkled or convoluted ; inter- 

 nally the colour is purplish (after repeated preserving) ; the 

 perithecia are arranged regularly round the periphery and the 

 part-spores measure 8-9 x 2 ^. The type specimen of Hypocrella 

 Spegazzinii Sacc. is Spegazzini, Fungi Argentini Pugillus IV., 

 No. 209, on Coutarea mollis, Brazil ; a specimen furnished by 

 Spegazzini is labelled "In foliis coriaceis, Apiahy, May '81. 

 Puiggar " ; this is the species listed by Spegazzini (foe. cit.) as 

 Hypocrella phyllogena (Mont.) Speg., and the herbarium specimen 

 bears that name. The stroinata are up to 5 mm. diameter, 

 broadly convex, up to 2 mm. thick in the centre, generally ridged 

 a short distance from the lower margin ; they are rough with 

 projecting ostiola, red-brown towards the base, black or blackish- 

 brown above ; the perithecia are arranged either regularly round 

 the periphery or at varying depths ; in general the stromata are 

 immature, but some contain part-spores 5-8 x 2 ^. The type of 

 Hypocrella guaranitica Speg. is Spegazzini, Fungi Guaranitici, 

 Pugillus I., No. 256, on living leaves of Euphorbiacess, near Villa 

 Rica, Brazil ; I have examined the type specimen from Herb. 

 Spegazzini : it is represented in Herb. Kew, Herb. Paris, and 

 Herb. Berlin by " B. Balansa. PI. du Paraguay, 1878-1884, 

 No. 3546. Feuilles d' Euphorbiacese. Santa Barbara, pres de 

 Villa-Rica, Fevrier 1882," which are apparently co-types ; the 

 specimens are associated with a Lecanium ; the Berlin specimens 

 are smoother than those at Kew ; they agree with Spegazzini's 

 description, but are Hypocrella palmce. The type specimen of 

 Hypocrella orbicularis Syd. (= Hypocrella globosa Syd., name 

 antedated) in Herb. Berlin, " Brazil. Prov. S. Paulo. Leg. F. 

 Noack. Comm. P. Sydow " has part-spores 6-10 x l'5-2 ^ ; old 

 specimens are purplish internally near the periphery ; the 

 stromata vary in roughness, some being almost smooth ; they 

 are associated with a Lecanium, : Hypocrella Sydowii Sacc. & 

 Trott. is merely another re-naming of the same gatliering. Hypo- 

 crella filicina Rehm, type specimen " E. Ule. Herbarium Brasili- 

 ense. No. 857, on Blechnum sp. Estado de Sta. Catharina, 

 Blumenau, July, 1888," in Herb. Berlin, is immature, but is 

 evidently H. palmss : the co-type in Herb. British Museum does 

 not contain any fungus, except a slight covering on one Lecanium,. 

 Hypocrella phyllophila Theissen, type ex Herb. Theissen, on leaves 

 of Myrtacese, Sao Leopoldo, Rio Grande do Sul, contains only 

 small specimens which do not differ from Hypocrella guaranitica. 

 Hypocrella aynbiensTheiss, " G. Rick, 1906, SaoLeopolda, Brazil," 

 ex Herb. Theissen, contains large black specimens, up to 10 mm. 

 diameter, minutely roughened, the ostiola scarcely projecting ; 

 the perithecia are more crowded than visual in a well-defined 

 cortical zone ; the specimens have been hollowed out by some
