et alphabetico, Hafnia 1827, Hornemann 57 h and R 85 g). El. Fries 

 has contributed much to the explanation of the figures of the »Flora 

 Danica« bv quoting them in S. M., the same is the case with Severin 

 Petersen (1907) and Raunki.^r (88); I have, in most cases, followed 

 the explanation of Rostrup. In only a few cases have I considered it 

 just to make some alterations. 



Oeder is the author of Chlorosplenium aeruginosum and of Hels 

 vella atra both brought to him by Koenig from Iceland. Oeder has 

 greatly promoted Danish mycology not only by giving the impetus to 

 the pubhcation of the "Flora D,\nic.\" but also by working enthusiasm 

 tically on the emancipation of the Danish peasants from villenage, this 

 being a necessary condition of the revival of interest in plant culture 

 and plant diseases among the farmers. 



The welbknown zoologist and botanist, 

 Otto Frederik Muller, succeeded Oeder 

 as editor of the "Flora Danica". He was 

 born in Copenhagen 1750. At first he studied 

 theology, but later on, especially after his 

 appointment as tutor to count Schulin of 

 Frederiksdal, he became a very enthusiastic 

 naturalist who made many discoveries of 

 microscopic animals and plants. He wrote 

 several dissertations on them, while travels 

 ling abroad, and his papers were so scattered 

 in different foreign periodicals that I have 

 been unable to make myself acquainted with 

 many of them. He did not content himself 

 merely with the portrayal and description of 



the discovered fungi, but was also deeply interested in their biology. He 

 describes (1775) how he has been watching Cordyceps miJitaris for hours 

 in order to observe how change of wind and moisture made the fungus 

 expel spontaneous clouds of spores. The same "dustingout", he has also 

 studied with other Ascomycetes f. inst. Bulgaria inquinans, Helvella 

 spp., Spathularia etc. He writes about Carpobolus that he has seen the 

 fungus fling out all its contents so that it described a parabola through 

 the air; if this shell meets some obstacle a crack like that of an Flater 

 is heard. In another place he describes the colourless, ovate spores of 

 the Agaricaceae and the spores of the Geoglossaceae, which under the 

 microscope are like "black, stiff sticks". Pilobolus crystallinus has led 

 him to write two dissertations (1768 &. 82, see also Hansen 1878). He 

 was a friend of "Konferenzraad Holm" (Holmskjold). They kept 

 each other informed concerning the observations they made of the 

 fungi. MCller was a diligent man who has made not a few con: 



O. F. Muller.
