which lasted during Mr. Ellis's life. Mr. Stevenson did a con- 

 siderable amount of work on the fungi of the Schweinitz herbar- 

 ium, his paper on the Valsei of the United States (44) being 

 based on Schweinitz specimens. 



In the course of his work on the fungi he to some extent re- 

 arranged the specimens and relabeled the portfolios. Steven- 

 son's labels give the numbers of the specimens included in each 

 portfolio, whereas the original labels as prepared by Michener 

 simply give the names of the genera included in the cover but not 

 the numbers. This is evident from four empty covers bearing 

 Michener's labels still preserved in the herbarium. In relabeling 

 the volumes Stevenson evidently placed more sheets in a cover 

 than Michener had done, which accounts for the four empty 

 covers left over. 



Certain specimens which were indicated as missing by Steven- 

 son on the folio labels, i. e., Nos. 1493 to ^63 and Nos. 1664 to 

 1809, were found some years ago in two packages labeled "This 

 package as it came from the Smithsonian Institution." The 

 sheets containing these specimens were placed in (their proper 

 places in the portfolios by Prof. J. C. Arthur and the senior writer 

 during a visit to the herbarium in February, 191 7, and a note to 

 that effect placed on the labels of the portfolios. This the writers 

 take to indicate that these specimens were loaned to the Smith- 

 sonian Institution before Stevenson relabeled the portfolios. 

 Duplicates of many of these missing specimens are in the Curtis 

 collection at Harvard. Dr. Farlow writes that there are 32 of 

 the 42 species of Puccinia mentioned in North American Fungi 

 (40) and 28 of these species are checked in Berkeley's personal 

 copy. The Michener collection contains specimens of 37 of 

 Schweinitz species of Puccinia. 



In the last volume of the fungi as now arranged Nos. 2905 to 

 2972 (containing Puccinia, etc.) also 2973 to 2997 inclusive are 

 missing. The original packets of Schweinitz are in the collection, 

 as are the portfolios, bearing Michener's labels, which originally 

 contained Puccinia and related genera. This indicates that 

 Michener mounted these specimens as well as the others and that 

 they disappeared subsequent to this work. In many cases where 

 specimens are missing in the mounted collection there are pin holes
