factory picture of the fungal flora of a region will on the лл^о1е 

 only be obtained, when a specialist visits the country and himself 

 collects his material. 



For friendly assistance in the examination of the Gasteromy- 

 ceteae collected I am much indebted to Dr. Ladilaus Hollös of 

 Kecskemet in Hungary and my friend cand. Winge of Copenhagen. 



Agaricineae. 



Cortinariiis Fr. 

 Cortinarius (Myxacium) coUinitus (Pers.) Fr. — Epier, p. 274. 



No. 270a (coloured drawing) : bog north of Thermometerfjæld, 4—6 — 07; No. 355: 

 near the large lake, 9-8—07; No. 1911: Danmarks Havn, 16—7-08; No. 1916: Basis- 

 kæret, 16—7—08. 



On the largest and best preserved specimens (No. 355) the belted 

 structure of the stalk is still to be seen; the other specimens are 

 less typical, but undoubtedly belong within the range of this species, 

 which is very variable. In microscopical regards they are quite 

 the same. 



This species, which seems comparatively common, has probably 

 been brought home from Greenland on earlier occasions, without 

 its being possible to determine the specimens; cfr. Rostrup: Fungi 

 Groenlandiae orientalis etc., Medd. om Grønland XXX, p. 15: "In 

 coUectionibus .... Agaricaceae .... indeterminabiles e generibus Rus- 

 sulae .... et Cortinarii inventae sunt".

No. 33a (coloured drawing): near the large lake, 1—8 — 07; No. 1766: in damp 

 moss, 18-7—08. 



Cystidia bottle-shaped, usually with a small knob or bud on 



the neck. In the material from Julianehaab I have found conical 



cystides, which however showed a tendency to swell out above into 



knobs; on the whole this species seems to contain several types in 



regard to the form of the cystidia.
