letters now kept in the Vet. and Agricult. College witness how people 

 of all classes came to consult him, not only in questions concerning 

 fungi, but also concerning all forms of botany, the culture of plants, 

 prevention of weeds and the legislation against parasitic fungi etc. 



Already while a teacher of science at the Training School of Skaas 

 rup (1858—1883) Rostrup occupied himself with all branches of myco* 

 logy, no group of fungi was unknown to him, indeed the substras 

 turn — be it living plants or animals, dead or foul remnants, earth 

 or water — will scarcely be found where he has not sought and found 

 fungi. He always made a note of what he found including it in his 

 herbarium so that his discoveries might be of use when an account 

 of all the fungi of Denmark should once be written. The explora? 

 tion of Denmark was of particular importance to him, and he most 

 frequently spent his summervacations in different, remote parts of the 

 country ardently collecting fungi; he several times stayed at Horn? 

 baek and Tisvilde in the north of Seeland, once in the Isle of Faene 

 in Lillebaelt, at Sseby in Jutland, in his native farm Stensgaard in Lois 

 land, in the Isles of Bornholm and Langeland. On these summer* 

 excursions Rostrup was always accompanied by his family : Mrs. Ro* 

 STRUP, their daughter Asta and sometimes also their son Owe; they 

 too contributed to the great treasures of fungi which were brought 

 back for the herbarium. Rostrup also frequently took part in the 

 excursions of the Botanical Society, and it is evident from the reports 

 of these that many fungi were always found when he was present. 

 As a teacher of the students in forestry at the Vet. &. Agricult. College 

 each year he was one of the leaders of one or more excursions to the 

 forests. Rostrup also liked to make little trips, most frequently to the 

 beautiful parts of the north of Seeland, together with a few friends 

 interested in botany ; his son, Ove Rostrup, F. Kolpin Ravn, S. Rut* 

 zow, C. Raunki^r, E. Warming and a great many others have joined 

 in those little, private excursions. 



Among the more remote parts of Denmark Rostrup once visited 

 The FiER0EsJI}le has also — though seldom — been abroad: he once 

 went to the Ditmarshes, paid three visits to Norway (Hamar 87, 

 Dovre 91, Valdres 1900) and two to Sweden (Sundsvall 82 and Bastad 

 02). These journeys often resulted in accounts of the fungi found 

 during the same (The Fasrees R 70 a, Norway 91 1, Sweden 83 b), 

 but Rostrup also spent much time and much strength in revising and 

 describing the fungi collected by others particularly in the Far North 

 (Ellesmere Land 06 bb, Greenland 88 b, 92 a, 94 d, 04 g, Iceland 

 85 b, 87 i, 03 b, Spitzbergen, Wulff 02, The Faroes R 96 r, 01 n and 

 Norway 86 m, 04 f, 05 a, 06 c) occasionally also fungi of quite exotic
