After the publication of his "Enumeratio", Schumacher proceeded 

 to other studies, especially that of shells. However, in the great work 

 on medical plants which he published in connection with Professor 

 Herholdt he did not forget the fungi, but he mentions their medical 

 use and their distribution. Among the various species of fungi named 

 after Schumacher is also — strange to say — Lachnellula Schumanni 

 Rehm (III '*^); it appears from the text that Rehm has wanted to 

 name it after the author of the similar Peziza calycina Schum. 



After the death of Vahl, the publication of the "Flora Danica" 

 was intrusted to his pupil Jens Wilken Hornemann (born at Marstal 

 March 6., 1770). In 1808 he was made extraordinary and in 1817 

 ordinary professor of botany at the University of Copenhagen, an 

 office which he held with great honour till he died in 1841. In many 

 respects Hornemann was a skilful botanist, but he wanted interest in 

 the fungi, and for this reason the long period in which he ruled 

 botany uncontrolled was a dull time for mycology in Denmark. The 

 number of figures of fungi published by him in the "Flora Danica" 

 have almost all been borrowed from the posthumous sketches of Vahl 

 or Schumacher. It appears from the text that El. Fries has assisted 

 him with their nomenclature. If Hornemann had had a little more 

 interest in the fungi than was then the case, he might have been more 

 attentive to the events during the so-called "barberry r^war" which was 

 raging like a second "Thirty Years' War" in this country during the 

 greater part of his professorial reigm. If he had followed Sch0ler's 

 remarkable experiments of infection of Aecidium berberidis with the 

 understanding they deserved, he might easily have repeated them 

 under other and safer conditions, thus making the discovery concern 

 ning the heteroecism of this species of rust which was made by de 

 Bary in 1866. 



A whole series of Danish botanists partly contemporaries of Horne* 

 MANN, partly his successors occupied themselves not at all with myco« 

 logy, and will not be mentioned here. From Schumacher to Rostrup 

 there is only one famous Danish mycologist, viz. 0rsted. This is all 

 the more strange as, during the same period, the interest in mycology 

 of our neighbouring country Sweden under the direction of El. Fries 

 wa\very great. 



Anders Sand0E 0rsted was born at Rudkjebing on lune 21. 1816. 

 His uncles on his fathers side were the famous statesman A. S. 0rsted 

 and the well-known physicist and natural philosopher H. C. 0rsted. 

 In 1854 he was made Ph. D.; on April 21. 1858, lecturer of botany, 

 1860 professor. He died Septbr. 3. 1872. He made a journey in Cens 

 tral America where, like Liebmann, he found a number of new fungi, 

 which were sent to Fries and described by him (Novae symbolae
