countries f. inst. Central Asia (07) and Siam (02 d) ; these works are, 

 however, outside the hmits of the present work. 



As a phytopatologist Rostrup occupied himself not alone with the 

 useful plants of agriculture but in an equal degree with those pertais 

 ning forestry and horticulture. The noxious animals were by no means 

 unknown to him, he took a great interest in entomology and zoos 

 cecidia, but he never pubhshed anything on these subjects, those parts 

 of pathology he left completely to his friend and colleague I. E. V. 

 Boas Ph. D. and his daughter-in-law Mrs. Sofie Rostrup M. S. Ros 

 STRUP limited himself to the parasitic fungi, and in his great and fine 

 work. The Pathology of Plants, published in 1902, he has given a 

 splendid account of the influence of the Danish (and some foreign) 

 parasitic fungi on cultivated plants. The parasitic fungi of wild plants 

 was of equally great interest to Rostrup (see the numerous reports of 

 his excursions in the "Botanisk Tidsskrift" and his mycological reports). 



He also took a great interest in Merulius lacrymans and other fungi 

 on timber (see R 76 a 6^ 98 a). On the whole Rostrup was consulted 

 every time the use or injury of fungi to man was discussed; when 

 useful domestic animals had fallen ill by eating food infected by 

 fungi, as also when parasitic fungi were to be used for the control* 

 ling of insect pests in hothouses or of caterpillars in the fields etc. 



Rostrup has also dealt with the taxonomy of the fungi f. inst. by 

 the preparation of the relevant part of Warmings Systematical Botany. 

 The biology of the fungi, the knowledge of their development, their 

 relation to their host^plants and — as far as concern the rusts — their 

 heteroecism is so closely connected with the phytopathology that 

 Rostrup was always much occupied with it; among his works on the 

 biology of fungi I must mention in particular those which, in the list 

 of literature at the end of the book, are called R 66, 74 a, 85 a, % b 6^ 

 96 o. 



Nobody was so familiar with the history of the research of fungi 

 as E. Rostrup; in Bricka's Biographic Dictionary he has written de* 

 tailed biographies of all the late Danish mycologists, and the greater 

 part of the information which I have collected below originates from 

 him. In the "Botanisk Tidsskrift", and other periodicals are numerous 

 obituaries of late mycologists written by Rostrup. Rostrup's studies 

 in Schumacher's herbarium is of particularly great value (R 85 g, see 

 also R 93 b, 98 q). It was a matter of course that he interested him= 

 self in the history of that branch of science in which he was so totally 

 absorbed. He has also collected all the legends and noted down all 

 the superstition referring to cryptogames (R 1875). Up to the very 

 last days of his life he continued to collect curious notices from news= 

 papers on the fungi which he kept in his scrapbook.
