 In thalli divisionibus rimse (fissurae) frequenter obveniunt transversa 

 vel obliquse. Variat thallus cinerascens et centro leviter fuliginosus 

 (subfurfurellus), — f. cinerascens. 



This species belongs to the section of P. adhcerens. It presents 

 somewhat the appearance of Squamaria saxicola, f. Garovaglii

(Krb.) ; but the colour is different, as also the analytical characters. 

 The sperniogones show that it is a Parrnelia, having arthro- 

 sterigmata with somewhat long thin articulations as in the Par- 

 nieliei. "With reference to the specific name, Nylander observes,

On rocks ; very sparingly gathered. 



Parmelia molliuscula, Ach. 



On rocks ; fertile. A state with more elongated and narrower laciniae 



also occurs, but with the apothecia not rightly developed. In the 



fertile specimens the spores are about 0*008 millim. long, 0*005 millim.

This species approaches P. Dregeana, Hmp., Nyl. Syn. p. 398, 

 from which, however, it at once differs (as also from P. stygiodes, 

 Nyl.) in the oblong form of the spores.

P. fuliginosa (Fr.). 



On rocks ; very sparingly gathered, there being only slight though suffi- 

 ciently distinct traces visible in a single specimen, associated with other 

 lichens. 



P. lichinoidea, Nyl., sp. Thallus subsimilis ut in P. lanata, sed de- 

 planatulus, laciniis depressis (latit. circiter 0'3 millim.); medulla K 

 non tincta. Apothecia et spermogonia non visa. 



On the summit ; amongst mosses on the ground.
