Fungi terrestres from North-East Greenland. 139 



"Seems to be one of the commonest Agaricaceae occurring in 

 Greenland" (Rostrup: Tillæg til Grønlands Svampe, Medd. om Grøn- 

 land III, p. 597). 



Iiiocytoe Fr. 



Inocybe lacera Fr. — Syst. Mnx. I, p. 257. 



No. 48a: Koldewey Island, 13—8-06. 



A covering of sand, containing protonema threads, small mosses, 

 a very small Juncus plant and withered stumps of older, still sur- 

 rounds the somewhat knob-shaped, swollen basal part of the stalk. 



This fungus thrives well on sandy, naked ground; the author 

 has found it on such a locality on heaths in Jutland. — Noted by 

 Rostrup from Danmarks (Øst-Grønlands Svampe, Medd. om Grøn- 

 land XVIII, p. 7). 



Lactarius Pers. 



Lactarius rufus (Scop.) Fr. — Epicr. p. 247. 



No. 48b: Koldewey Island, 13^8—06; No. 381b: Thermometerfjæld, 17—8-07. 



The anatomicai examination of the trama shows that the fungus 

 is a Lactarius or a Riissula. There is nothing stated regarding the 

 milk contents; but most fortunately Lactarius rufus belongs to the 

 fungi, w'hich resist excellently the influence of the preserving fluid, 

 so that it is easilj^ recognised even in alcohol. 



The fungus is noted by Rostrup from Danmarks (Øst- 

 Grønlands Svampe, Medd. om Grønland XVIII, p. 8); it is of rather 

 common occurrence on Danish heaths. 



Naucoria Fr. 

 Naucoria sp. sc. N. lapponica Fr. — Hym. Eur. p. 263. 



No. 1935: Bog near Danmarks Havn, 16—7—08. 



A small specimen (stalk ca. 2 cm. high, pileus IVa cm. broad), 

 with quartz grains firmly attached to the surface of the pileus. 

 Spores ellipsoidal, 8 — 10 /j. x 5 — 6/^, light-yellow with oil-drops. — 

 Colour of the pileus is now dark-brown, but on drying yellow spots 

 come to view which have been very apparent in the fresh state» 

 this is indicated by a note in the journal: "honej^-fungus". The 

 pileus has thus been covered by bright yellow scales, and the pel- 

 licle has been viscous; add to this, that the lamellae are toothed at 

 the edge and with decurrent teeth, and it becomes very probable that 

 we have N. lapponica Fr. before us. — Unfortunately, no microscopic 

 characters have been included in the diagnosis of this species, which 

 makes the identification very difficult. — Rostrup notes A'^. lapponica 

 Fr. from Cape Stewart (Øst Grønland Svampe p. 7).
