Thallus K — superficie mox aeruginoso-sorediosa insignitus; 

 gonidia thallina 6 — 8 ii diametro aequantia, ilia autem quae in 

 margine thallino apotheciorum occurrunt 10—12 \u lata sunt; 

 aliadein thallinis conformiasub hypothecio quasi gregatim nidulant^ 

 quae omnia ubi copiosius adsunt, sectiones nonnihil aeruginosas red- 

 dunt, sed nihilomiuus vere chlorophyllosa sunt, sc. nee K nee SOs colo- 

 re mutantur. Spermogonialeviterprominula, nigro-punctiformia. 



Juxta Lecanoram epanor am And. inserenda est, a qua colore 

 thalli et sorediorum, apotheciis neutiquara vitellinis et sporarum 

 ibrma ntrinque acuta v. hinc inde acutissima valde distincta est. 

 Apotheciis quodammodo Lecanoram Trevisani Heppii refert, sed 

 Thallus et sporae omnino alia. Sporae ad illas Leeanorae 

 iadiae accedunt, sed reliqua longe differunt. — Acharius pri-
