 caule ramoso, ramis pyxidatis, in extremitates minores, pyxidatos 

 cristatos desinentibus, punctis fuscis undique terminatus. In 

 trunco putrescente fagi. Rarior haecce varietas apud nos est, 

 quae externo habitu similis Licheni pyxidato prolifero nostro, dif- 

 fert caule ramosiore, terminato superne in pyxides proliferas, 

 quarum minores difformes, in minores protenduntur pyxides, in- 

 star ramusculorum, margines priorum obsidentes. Minorum ista- 

 rum pyxidum laciniatarum extremitates terminantur in exigua 

 fusca tubercula, quae ob magnam copiam totum lichenem crista-
