THE FIRST DISCOVERY. It was always of interest to Rostrup 

 to ascertain who first found a certain fungus in this country as also 

 when it was first found; so I have, for many species, stated the day 

 and the year of the discovery and the place which, according to the 

 present information, may be considered the first place where it was 

 found; for most species it is only of interest as a curiosity, as we are 

 obliged to take it for granted that the species was to be found in this 

 country long before that time; still it gives some useful information 

 for instance as to the progress of knowledge of the fungi in the course 

 of time. "With regard to a number of fungi, especially those causing 

 damage to cultivated plants we have reliable information stating that 

 they were not found in this country before the stated period (Sphaes 

 rotheca mors uvae, Uromyces betae, Puccinia malvacearum, Monilia 

 crataegi, cinerea &. fructigena). The dates and the places given are also 

 of further importance in showing how those species of fungi are 

 continuously to be found in the same; localities. Uromyces phyteu* 

 matum was found by Rostrup at Klokkedalen near Horsens in May 

 1885, and I found it in the same place in 1902; J. Jeppesen (Ranum) 

 found Puccinia littoralis at Horsens Fjord in 1876, and it is still found 

 there; C. Gad found Pseudoplectania nigrella in a spruce plantation 

 near Viborg Norreso in February 1884, and I found it in the same 

 plantation in 1906; numerous similar examples are stated in the text. 



On the other hand it is often noticed that fungi which have, for 

 some years, been very common will completely or almost completely 

 disappear; see for instance Puccinia apii, Puce, chrysanthemi etc.
