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). 



Inocybe Fr. 

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



No. 48a: Koldewey Island, 13-8-06. 



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

 a very small Jiinciis 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 Russula. There is nothing stated regarding the 

 milk contents; but most fortunately Lactarius rufus belongs to the 

 fungi, which resist excellently the influence of the preserving fluid, 

 so that it is easily 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 I'i cm. broad), 

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

 Spores ellipsoidal, 8 — 10^ 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 stated 

 this is indicated by a note in the journal: "honey-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 N. lapponica 

 Fr. from Cape Stew-art (Øst Grønland Svampe p. 7).
