 apphcatinii ol' K intinsiTKd the i-eaetion. The test was made with fresh C, 

 it was never donhtliil, hut in some plants it was necessary to rub the 

 denudatcd medulla to obtain the reaction. The colour is most intense near 

 the stratum gonidialt. 



The i-est of the material ( 1 20 - 130 plants) was C -i-. A great part 

 of it gave a distinct red colour by K + C, another equally great part was 

 K + C negative, in some specimens the medulla took an impure brownish 

 or bi-ownish-red colour at the stratum gonidiale, or the reaction was 

 faint and doubtful. It seems to me that we cannot use a reaction of this 

 nature for the further subdivision. 



AcHARius describes the y. ccrntrn with wonted master}-; laciniis angu- 

 statis subei-ectis convexo-subcylintlricis coi-niculato-ramosis acuminatis cinereis 

 laevigatis nudis' (Lieh. Univ. p. 501, Meth. p. 255). 



There are 45 specimens in our Norwegian herb, which I have referred 

 to the ccratca according to the Acharian morphological description (se also 

 Krypt. Exsic. Vind. No. 768). 26 of them ga\-e a more or less distinct 

 positive reaction with K + C, 19 no reaction. No less than 20 specimens 

 were fertile. Some of them habitualh- agree entirely with narrow olivcto- 

 riiia, but they are C -^. 



I cannot grasp the eventual morphological difference between Zopf's 

 furfuracca and isidiopJwra, and I have refeiTed the rest of m}' material (ca. 

 80 specimens) to the Acharian var. scohiciiia : 'laciniis extrorsum latioribus 

 subdigitatis obscure cinereis floccoso-furfuraceis squamulosisque' (Lieh. Univ. 

 p. 501). — I have tested some of them and found a greenish colour in 

 the ether extract, indicating the isidiophora. Ca. 45 scohiciiia-'Çi\?LnX.s were 

 K + C rubescens, 30 negative, and some doubttul. 



Apothecia are not common in the var. scobiciua.
