Studies of the Schweinitz Collections of Fungi 199 



nitz's Flora of Salem, North Carolina, which also contains mar- 

 ginal notes of plants that he collected in the vicinity of Bethle- 

 hem. The date of this manuscript is 182 1 — it is a book 8 by 13 

 inches with 165 pages, of which 120 pages are devoted to Pha- 

 nerogams, 4 pages to Filices, 11 pages to Musci and Hepaticae, 

 3 pages to Fresh Water Algae, 22 pages to Lichens. 10 This is 

 evidently the unpublished portion of a flora of the vicinity of 

 Salem, N. C, of which The Synopsis fungorum Carolinae Su- 

 perioris formed a part. 



Mr. Rau also has " an index to his herbarium 1822," a book 

 which " contains a list of his correspondents with their addresses/' 

 an " Index Herbar, Europ." and a " list of Amer. Fungi in his 

 collection." 10 



In the Library of the Academy of Natural Sciences, Philadel- 

 phia, are the following manuscripts dealing mostly with Fungi : 



Schweinitz's Index to his herbarium marked : " Index Herbarii Ludovici 

 Davidis de Schweinitze 1824. Adjectis plantis ' omnibus Zonae temperatae 

 Graminaceis autem ac Cryptogamis totius orbis." 



This is a large folio volume of several hundred pages, not 

 numbered, containing a MS. list in Schweinitz's handwriting of 

 the species contained in his herbarium. There is a final sum- 

 mary on the last page dated July, 1828, giving a list of the various 

 orders of plants and the number of each. The grand total is 

 16,266 specimens, 2,800 of which are fungi." 



Also a manuscript on octavo sheets with the following title: 



" Description of some new American Species of the Genus Sphaeria being 

 the first Genus of the Second Order Pyrenomycetes of the Second Class of 

 Fungi Gasteromycetes according to the system of Mycology of Dr. Elias Fries 

 supplementary to the Synopsis of Carolinian Fungi by L. De Schweinitz pub- 

 lished in the Comentaries of the Society of Naturalists of Leipzig by Dr. 

 Schwagerichen." 



There are also three folio volumes of unpublished plates en- 

 titled " Fungorum Nieskiensis Incones " in the library. Mr. Rau 

 states that at one time six or seven volumes of colored plates 

 were loaned him by Schweinitz's son, Bishop Edmund de Schwei- 

 nitz. Where these are is now unknown. There is now in the 

 possession of Mrs. Lemly, a granddaughter of Schweinitz, of 



10 Extracts from letter written by Mr. Rau, February 8, 19 17.
