Iciicoraca. Two small piants from (ijoa i iarbour. Apothecia convex, 

 spores rather broad: 18-21 X 'o n ,". 



This species was recorded from KUesmereland: Goosefjord, Sec. Norw. 

 Arct. Exp. Fram (1909) p. 30. The plant from Eilesmereland has plane 

 disc and albopruinose margin (Calop'.aca stillicidionini) .

papillala (Somrft.) Arn. Wain. Pitlekai p. 83, ubi syn. Herschel 

 Island, very common, with Cetraria nivalis, Thamnolia vermicularis, Physcia 

 umscigena, the two Caloplacae, Lecanora cpibrya and Lecanora verrucosa. 



Thallus albissimus, crassus, verrucosus vel etiam papillatus. Apothecia 

 primo plana, margine tenui circunidata, dein niox convexa, margine 

 evanescente. Hymenium 80 — 100 //, J. e caeruleo sordide vinosum; hN'po- 

 thecium obscurum, paraphyses facile discretae, apice nigro-capitatae, asci 

 octospori, sporae — saepe angustae — ellipsoideae vel subfarinaceae, 

 17 — 26 X 8 — 10 //. 



These specimens agree well with Sommlrfelt's authentic specimens 

 in our herb. The white colour and the thick papillate thallus distinguish 

 it from the (parasema) iiinsconmi.
