Affinis C. niwvali Ach. et C. cucullatæ Ach., a quibus thallo non lacunoso et denticulato, 
colore minus stramineo et spermatiis aliis jam recedit. 
TRIBUS IV. — ALECTORIEZÆ. 
Thallus fruticulosus, erectus pendulusve aut raro decumbens, cylindricus, raro 
compressus, undique concolor aut interdum in facie postica pallidior, semper similiter 
corticatus et intus symmetricus. Cortex varie coloratus, angustus cum zona medullari 
subjacente ex hyphis axi parallelis constitutus et ab hac non differens nisi hyphis stric- 
tius coalitis. Gonidia protococcoidea; hyphæ medullares plus minusve evolutæ ; axis cen- 
tralis lacunosus. Si thallus castaneus, nigricans, albidus vel stramineus, cylindricus aut 
filiformis, erectus, pendulus aut subdecumbens, fibrillosus, genus A lectoria. Si thallus 
nigricans, cylindricus et prostatus, genus Cornicularia. Si thallus aut flavicans, cylin- 
dricus et fibrillosus, aut cinerascens, cylindricus aut compressus, aliquando villosus aut 
spinulosus, 'genus Zheloschistes. Si thallus subtus canaliculatus, villosus aut margine 
ciliatus, genus Anaptychia.
