Thallus vulgo flavescens, KHO non reagens, soredioso-leprosus, 

 continuus aut dispersus, granulis sorediorum tenuissimis aut grossis 

 et verruculaeformibus, hypothallo indistincto aut inter acervulos sore- 

 diorum plus minus distincto et ex algis immixtis nigricante, acidum 

 rhizocarpicum continens (sec. Zopf in Ann. Chem. 284, 1895, p. 117, 

 Flechtenst., 1907, p. 402). Apothecia parce evoluta, lat. O.s — O.25 mm, 

 crass, usque ad 0.4 mm, saepe in hypothallo nascentia, vulgo sat late 

 adnata, basi bene aut leviter constricta, baud pruinosa, opaca, ceterum 

 etiam intus sicut in v. orenicola, disco piano, demum depresse convexo, 

 margine sat tenui aut modice incrassato, haud raro primum prominen- 

 te, vulgo persistente. Hymenium circ. O.200 mm crassum. Epithecium 

 fuscescens aut fusconigrum, HNO3 aut H2SO4 mox aeruginosum, KHO 

 rubricoso-rufescens. Hypothecium superne (usque ad O.oso mm lat. 

 albidum, inferne non differens a perithccio et fusconigrum aut rubri- 

 coso-fuscescens, at HNO3 non reagens, KHO rubricoso-rufescens, H2SO4
