HYPOCRELLA AND ASCHERSONIA. 227 



collected by Spruce, and compared it with the Indian species, 

 stating that its spores differed in length, but the difference was 

 not enough to constitute a distinct species ; he had changed the 

 name to A. oxyspora. In Jour. Linn. Soc, X. (1869), Berkeley 

 gave a list of Cuban fungi, and on page 351 of his paper he 

 described Aschersonia cuhensis B. & C, adding " River Amazon." 

 This addition indicates an extra-Cuban locality for the same 

 species, and as Berkeley stated in liis introduction that he had a 

 complete set of Spruce's specimens from the Amazon available for 

 comparison, it is probable that the Amazon record refers to the 

 same specimen as that previously recorded under the name of 

 A. oxyspora. In Jour, Linn. Soc, XV., however, Berkeley and 

 Cooke compiled a full account of the fungi of Brazil then known, 

 and there they hsted " No. 373. A. cuhensis B. & C. Cuban 

 Fungi, No. 557, Brazil (M. J. B.)," and "No. 374. A. oxyspora 

 Berk ; in Hook. Jom\ (1856), p. 278. On dead leaves, S. Carlos, 

 Spruce." It would ap^jear that, as far as Brazil is concerned, 

 these records refer to the same gathering, i.e., that by Spruce, on 

 dead leaves, S. Carlos ; tliis specimen is in Herb. Kew., sub 

 Hypocrella oxyspora, and consists, as stated, of small specimens 

 of A. turhinata. 



In Bull. No. 13, U. S. Dept. of Agriculture, Division of Vege- 

 table Physiology and Pathology, H. F. Webber has recorded 

 Aschersonia turhinata from Florida on Ceroplastes floridensis on 

 Orange, Mandarin orange, and Hackberry {Celtis occidentalis). 

 Webber describes the stromata as wliite, and states that the 

 conidia when extruded are orange rufous to cinnamon in mass. 

 His figures leave no doubt as to the accuracy of the identification. 

 There are specimens on Ceroplastes on Citrus from Florida, 

 collected by E. W. Berger, in Herb. British Museum. 



Mr. F. W. South has furnished me with specimens from St. Lucia 

 on Java plum, from Dominica on mango, and from Trinidad on 

 Lecanium {? mangiferse) on Guava. Some of these specimens are 

 sub-hemispherical, i.e., their sides are convex, not vertical ; most 

 of them are truncate and concave above, but one bears two 

 concave surfaces (not stalked), placed obliquely and meeting in a 

 ridge at the apex. The fungus has been recorded from the West 

 Indies as Hypocrella oxyspora Mass. Specimens have been sent 

 me from Trinidad and Grenada by Professor Thaxter. 



In perithecial specimens from Professor Thaxter, the stromatf'' 

 are hemispherical or subglobose, tuberculate, minutely tomentose. 

 The pycnidial disc is usually situated on one side, sometimes 

 towards the base, and embedded in the stroma, and presents the 

 appearance of having been displaced from its usual apical 

 position by the continued growth of the basal part of the pycnidial 

 stroma.
