Saepe in var. Weberi (Ach.) transit, praesertim quum tan- 

 turn partim pruinosus est, sed saepe etiam a D. miniato var. 

 complicata vix certe distingui potest. Humectatus thallus flacci- 

 dior est, quam in posteriore, sed minus flaccidus, quam in priore. 

 Haec nota e textura strati medullaris et crassitudine thalli depen-

 mm crassis, sat leptodermaticis, haud conglutinatis, profunde lo- 

 batus, lobis circ. 7—2 mm latis, complicatis, explanatis concavisve

 sat tenuiter pruinosus, inferne nigricans, haud pruinosus, sporae
