Studies of the Schweinitz Collections of Fungi 197 



abandoned the abbreviation, L v S in his manuscripts. This 

 change may have been due to his habitually writing his scientific 

 papers in Latin or, as suggested by Dr. George de Schweinitz in 

 a recent conversation, it may very probably have been done out 

 of consideration for his wife, who, as mentioned above, was of 

 French ancestry. His sons all retained the later form. 



Mycological Publications 



Following the joint paper with Albertini mentioned above, 

 Schweinitz's next mycological publication was the Synopsis fun- 

 gorum Carolinae superioris (10). The circumstances of its pub- 

 lication are given in a letter to Torrey. 8 



" I would have deferred writing longer had not the present good oppor- 

 tunity afforded for transmitting to you a copy of a small work bearing my 

 name on its title page, which was sent to me from Germany — to my no small 

 surprize, as I was utterly unaware that it would be published — although I 

 must confess myself the author. I left it with a friend some years ago, with- 

 out any such idea, but have no objection that he disposed of it that way. 

 Possibly it will be not uninteresting to you, as it contains a list of all the 

 fungi I had observed in N. C. previous to 1817, with definitions of the new 

 ones, and I therefore beg of you to accept it as a token of my friendship." 



The date of publication of this paper is given by Johnson as 

 1818 with the remark: "The date of this paper is only men- 

 tioned on personal information." The source of this " personal 

 information " is unknown and there is no definite indication as to 

 its authenticity. The volume, of which this paper forms a part, 

 was published in 1822 and bears that date. Schweinitz's paper 

 is, however, in the early part of this volume (pp. 20-132) and 

 there is a copy of a separate in the Library of the Philadelphia 

 Academy paged 1-105 but hearing no date. This separate was 

 received for the Academy by Z. Collins in December, 1822. 9 

 That Schweinitz himself did not receive copies of this paper until 

 late in 1822 is shown by the letter just quoted and as he was 

 in Europe during 1818 it is improbable that the paper could have 

 been issued then without his knowledge. 



In 1825 Schweinitz published a short paper entitled Descrip- 

 tion of a number of new American species of Sphaeriae (12).
