the black ostiola of the pycnidcs). Acharius is inclinea insider the 



stciiophylla a proper species: 'difficile est dictu utrum varietas cujuspiam 

 harum sit \'el propria species'. 



In Lieh. Univ. (18 10) p. 487 xXcharius reduces the value of steiio- 

 pJiylla: 'Prioris (z) — i. e. the type — mera varietas'. 



The Swedish lichenologist G. Einar Dr Rietz called my attention to 

 the specific \alue of the stciiophylla, and I agree with him on this point. 



Paniirlia stciiophylla is larger than Paniiclia coiispcrsa, it is more loosely 

 affixed to the substratum, and it has narrower, longer, and more imbricate 

 laciniae. There are no isidia, but small marginal secondary laciniae are 

 not rare. 



There is a certain correlation between the morphological and the che- 

 mical difference. Pannclia stciiophylla (I have tested our whole material) 

 nearly alwa3's gave a distinct red colour with KOH, Pannclia coiispcrsa a 

 more irregular reaction: a few specimens a purely yellow colour, the greater 

 part an intermediate, orange colour, and some specimens an intensely red 

 colour. Our specimen of Anzi Lieh, it no: Iiiihricaria coiispcrsa f. isidiata 

 Anzi gave a yellow colour with KOH ; no crystals were seen. — This 

 should be investigated by a chemist. 



I have seen no Norwegian specimens agreeing with the short and in- 

 sui'ficient descriptions of Parni. loxodcs Nyl. 



Harmand writes (Lichens de France p. 513) that P. loxodcs is the onl}' 

 species of this section which has the reaction 'medulla K Ca Cl + rose.' 

 According to Nyl.ander Pyr. Orient, p. 5, Pannclia litsitana is also 'medulla 

 K lutescens, K (Ca CI) suberythrinosa'. Harmand's specimen of P. lusitaiia 

 (Lieh. Gall. rar. 113) gives no red colour with KOH + Ca CI., 0.,, the yellow 

 KOH-colour is docolorated, at least not intensified, by Ca Cl._, O.,. 



Steixer has arranged the formae of P. coiispcrsa (incl. of the liisitaiiica 

 Nyl.), Oesterr. Bot. Zeitschr. 19 16 p. 377. He says: 'Medulla KHO varie, 

 saltem maculatim rufescens: planta typica' and 'Medulla KHO ut in pi. typica 

 colorata: var. isidiata Axzi.' —
