Thallus sat tenuis aut partim mediocris, subcontinuus 

 aut areolato-diffractus, albidus aut jjartim sordide ochraceo- 

 pallidus, quae partes KHO distinctius ochraceae, ceterum 

 neque KHO, nee CaClgOo reagens, sorediis destitutus, hypo- 

 thallo nigricante ad ambitum evoluto. Medulla jodo caeru- 

 lescens. Apotheeia 1,4 — 0,8 millim. lata, vulgo elevata ba- 

 sique leviter constricta, disco demum convexo, vulgo cae- 

 sio- aut caesiooehraceo-pruinoso aut pr. p. denudato, opaco, 

 margine mediocri aut demum attenuato, concolore cum disco.
