Mycologia 



of Wilmington, the paper on which the fungi were mounted being 

 furnished by the Academy. 



The manner in which Michener mounted the herbarium has 

 been described and illustrated by the writers in another connec- 

 tion (41). It should be noted, however, that in transcribing the 

 labels Michener sometimes did not include all the data given by 

 Schweinitz. For example, the autograph label on the empty 

 packet of Sphaeria intermedia L. v. S. says " Bethl in Crataego." 

 The host is not given on the label in the mounted collection. 



From the data which the writers have been able to gather it 

 now seems certain that Berkeley never saw the whole of 

 Schweinitz's collection. His work was based on material from 

 three sources, the specimens sent by Schweinitz himself to Dr. 

 Hooker, referred to above, specimens which Schweinitz gave 

 Torrey who sent them to Curtis, and the specimens which Curtis 

 obtained from the herbarium of the Academy of Natural Sciences 

 in the fall of 185 1. The greater portion of the specimens which 

 Curtis had he divided with Berkeley and these are now deposited 

 at Kew. 



In the published work of Berkeley and Curtis (4), there is no 

 indication as to the source of the particular specimen examined. 

 But in Berkeley's personal copy of the " Synopsis Fungorum in 

 America Boreali " (40), now in the library of the U. S. Depart- 

 ment of Agriculture, many of the species are checked in pencil 

 with a small mark V, " C," " H," or with two of these symbols. 

 This the writers take to indicate the source of the specimen, 

 whether from the Hooker collection, loaned by Curtis, or a part 

 of Berkeley's own herbarium. For example, Sphaeria radicalis 

 is marked " C " and " H " and there are specimens of this species 

 in Hooker's herbarium and in the Curtis herbarium at Harvard; 

 while 5. gyrosa is marked " H " and a specimen has been found 

 in Hooker's herbarium. In the early part of the book the species 

 checked are chiefly those on which comment is made in the 

 " Commentary on the Synopsis Fungorum in America Boreali 

 media degentium, by L. D. de Schweinitz " but the marks occur 

 throughout the book. 



In the light of the fact that Curtis (see p. 336) sent Berkeley 

 " about 300 specimens " to be returned later, it is of interest to
