142 Journal of Mycology [Vol. 13 



correspond very closely to the text printed in Usteri's Annalen, 

 with the publication of which Persoon did not seem to have been 

 acquainted at the time since he made no mention of it. Per- 

 soon's "adnotationes" occupied pages 120-130, while the "Com- 

 mentatio de fungis clavaeformibus" constituted pages 133-236 

 of the text, pages 237-239 being explanations of the four colored 

 plates. 



In the same year (1797) Persoon's Adnotationes and Com- 

 mentatio alone were printed separately by the same publisher 

 (Wolf), and under the title: "C. H. Persoonii commentatio de 

 fungis clavaeformibus sistens specierum bus usque notarum 

 descriptiones cum dififerentiis specificis, nee non auctorum syn- 

 onymis." There were 124 pages of text with 4 colored plates. 

 While I have not collated the texts, pages 1-104 correspond page 

 for page to pages 133-236 of the volume mentioned in the last 

 paragraph, except that on pages 101-104 a slight difference in 

 the spacing of some of the paragraphs makes a slight change 

 in the lines on the pages. The "adnotationes" occupied pages 

 107-116. The explanation of figures on pp. 117-118 is more 

 condensed, while the addenda, pp. 105-106, and the indices, pp. 

 1 19-124, are new matter. The 4 plates are the same. 



This separate publication of the Commentatio, Persoon said, 

 was intended for the convenience of those who already possessed 

 the 17th fascicle of Usteri's Annalen in which Holmskjold's 

 Coryphaei had appeared. 



After the death of Holmskjold, in 1794, his effects were 

 sold at auction, and the whole edition of his 1790 publication 

 together with all his descriptive notes and copper plates were 

 purchased by the agent of the king. From these manuscripts a 

 second volume treating of the other groups of fungi was pre- 

 pared under the editorship of Eric Viborg, so that in 1799 the 

 "Beata ruris" was issued in two volumes. Whether volume one 

 of this work consisted of the remaining undistributed copies of 

 the 1790 publication or was a reprint from the original plates 

 could not be determined. The work does not seem to l)e very 

 rare and is frequently referred to in mycological literature. 



From what has been said it will be noted that Holmskjold's 

 text has appeared in four forms: (i) as a privately distributed 

 folio volume with plates, 1790; (2) as a contribution to Usteri's 

 Annalen without plates, 1795; (3) as a volume edited by Per- 

 soon without plates, 1797; (4) as volume i of "Beata ruris," 

 etc., with plates. 1799. Persoon's Commentatio appeared first 

 in his edition of Holmskjold. 1797. and in the same year as a 

 reprint from the last with a modified title and slightly modified 

 text.
