Thallus interdum hypophleodes, plerumque epiphleodes, albidus, cinereus vel obscure 

 cinerescens, tennis aut parum crassus, nunc parum inœquatus, nunc granulosus verrucosusve, 

 hinc inde hypothallo cœruleo nigricante limitatus et etiam in partibus lœvigatis, inter 

 verrucas, obscure caeruleus atque hydrate kalico non mutatus. Cortex 20-40 [j. crassus ; in eo 

 hyphœ intricatae, 4-5 jx crassœ, articulatœ articulis brevibus, sepimentis crassis et lumine 2 [x 

 lato, ramosœ et aliquando in zona externa horizontales, lumine parvo aut vacuo ; in thallo 

 hypophleode fragmenta corticis arboris inter hyphas et gonidia ac etiam supra priores 

 conspicua. Gonidia viridia, protococcoida, 8-14, imo 20-24 li. lata, in strato sat crasso vel 

 in glomerulis sub cortice vigentia ; inter ea hyphœ 5-6 [x crassœ, pariete tenui, constricte 

 septatœ et sat stricte coadunatœ. Hyphœ medullares nunc horizontales, nunc verticales et 

 ramosœ. Apothecia 0,5-1,5, vel fere 2mill. lata, ab origine e thallo liberata, supra thallum 

 elevata, aut dispersa et rotunda, aut contigua et angulata, interdum lobulata, in basi con- 

 stricta etsi lobulo thallino circumdata, perithecio disco concolore vel pallidiore, interdum rufo,
