K.'ii-f ;iii(l <iiil\' f)ii the iiK.iiiii.iins in ICastern Norway, rather common 

 at alpine and subalpine stations in Western Norway. At the inland end 

 of the western fjords it descends to ca. 500 m. s. m., on the west coast 

 it is quite coinindn down to the level of the sea. Looked after^ in vain in 

 Troms and I'inniai'k fylke. 



iXpothecia and pycnides are common. 



Apothecia subtcrminalia, diam. 2 — 3.5 nun., lihiillosa vel crenulata, 

 discus piceus usque nigricans, epruinosus, nitidulus, plana et margine tenui 

 circumdata deniiini con\'e.\a margine excluso. Cortex exterior receptaculi 

 hyphis + cornels formatus, cortex interior crassitudine irregulari, usque 130 |x 

 altus, hyphis subplectenchymaticis formatus. Medulla receptaculi laxe contexta, 

 gonidiis lere carente. Hypothecium achrouiii, 20 — 25 — 50 [j. altum. Hyme- 

 nium angustum, 60 — 75 [v-, non inspersum, superne obscure flavo-fuscescens, 

 Strato amorpho crasso tectum. Paraphyses conglutinatae, apice capitatae, 

 + ramosae. Asci pyriformes. Sporae octonae, ellipsoideae, tenuiter lim- 

 batae, 8 — 9.5-4.5 — 5 [J. (Tu. Fruvs Scand. p. 29: 8 — 11 -;4 — 6 [j.). 



Pycnoconidia recta, bacillaria, utnimque versus apicem incrassata, 



5-8 K I [7.. 



React. Hymenium J persistenter intense caerulescens. 



The best known name h'islis dates from Weber Spicil. (1778) p. 209. 

 A. L. Smith refers this species to Paruiclia and introduces an older name 

 coriiiciilafa Lightf. Fl. Scot. II 1 1777) p. 885. But Gun.xercs' name is the 

 oldest, his Flora norvegica has 1772 on its title-page, in reality it was 

 printed in 1776,^ one year earlier than Lightfellow's Fl. Scot. 



I am indebted to H. Printz, curator of the botanical collection of the 

 kgl. Videnskabers selskab in Trondhjem for permission to studying Guxne- 

 Rus' lichen herbarium. As duly observed by several authors (Acharius 

 Lieh. Univ. p. 610 and Th. Fries Lieh. Scand. p. 28 Paniiclia piibcscctis is 

 admixted the '//orniöric/is'. But Gunxerus was fully aware that they were 

 two different species. This is evident from his herb, label: No. 973(8:974. 

 'Lic/icii normöricus & parasiticus'. The 'parasite' is Panuelia piibcscens. His 

 fig. is not good, he has also depicted the parasite. 



5. Cetraria odontella Ach. 



Akcrsh. Bærum: Kolsaas (Kiær). 

 Opl. Vaage: Visted (Th. F^r.). 



Evidently an eastern plant which only rarely passes our frontier. 



Only seen sterile in Norway. — The tips are sometimes sorediate. 

 1 have been unable to see the blue J colour of the medulla ('intus jodo 

 dilutius caerulescit' Th. Fr. Lieh. Scand. p. 100).
