Jeu lagde i 1890 ligesom det foregaaende Aar særlig Vægt 

 paa Indsamling af Svampe, og jeg har da ogsaa, som det vil 

 ses af "Conspectus floræ groenlandicæ», forøget Floraen med 

 et anseligt Antal nye Arter; jeg skal blot anføre, at jeg i 1889 

 fandt 46 Svampe-Arter alene paa Birk, hvoraf de 30 vare nye 

 for Grønland og adskillige nye for Videnskaben. I 1889 og 1890 

 har jeg ialt fundet 135 Svampe-Arter, der vare nye for Grønland, 

 hvoraf 22 ere nye for Videnskaben. 



Den grønlandske Svampe-Flora er som bekjendt meget rig. 

 Agaricaceer findes ganske vist ikke i stort Artsantal , men 

 mange af Arterne optræde i kolossale Mængder, særlig i Efter- 

 sommeren. 1 Fjeldmarken erindrer jeg ikke at have trutfet 

 dem, dér er Jordbunden for tør og for fattig paa de for Svam- 

 pene nødvendige Humusstoffer; i Lyngheden træffes de mere 

 almindelig, navnlig naar den ikke er altfor tør; her ser man 

 yderst almindelig Boletus scaber, Russida emetica. Omphalia 

 umbellifera og Lycoperdon aemmatui». .Men vil man træffe den 

 rigeste Agaricacé-V\ori\, maa man søge til Kjærene, til Urte- 



ScoresLy undersoste ogsaa den farvende Substans under Mikro- 

 skopet; af hans Beskrivelse har man Grund til at formode, at han har 

 set 2'JtfihiSf{o!^i)a eller en lignende Diatomé: "The fibrous or hair- 

 like substances, were more easily examined, being of a darker colour 

 They varied in length from a point to one-tenth of an inch; and when 

 highly magnified, Avere found to be beautifully moniliform. In the lon- 

 gest specimens, the number of bead-like articulations was about thirty; 

 hence their diameter appeared to be about the 1—300 th. part of an 

 Inch'. Some of these substances seemed to vary their appearance; but 

 whether they were living animals, and possessed of locomotion, I could 

 not ascertain. From one of the larger specimens I observed some 

 fine collateral fibres. They possessed the property of decomposing light, 

 and, in some cases, showed all the colours of the spectrum very di- 

 stinctly. The size of the articulations seemed equal in all, the dilfe- 

 rence in length being occasioned by a dilference in the number of the 

 articulations. The Avhole substance had an appearance very similar to 

 the horns or antennae of shrimps, fragments of which they might pos- 

 sibly be, as the squillæ are very abundant in the Greenland Sea» (э:
