autem cellule corticales cerulescunt. Apothecia minwta rotundata—varie difformia (num- 
quam tamen stellato-divisa). Hymenium epithecio carens, cum hypothecio similare, sor- 
dide fuscum, cellulis corticalibus frequentibus sepe immixtis. Asci late pyriformes, 
membrana superne haud multum incrassata. Spore parvule, 13—15 u long, circa 6 
u crasse, elongate oviformi-oblongee, cellulis vulgo 4, suprema omnium longe mazima. 
J hymenium cerulescit (quod tamen ob colorem primarium sepe minus clare elucet).

maturas frustra quesiverimus; species est hujus sectionis pene optime evoluta, thallo 
distineto albo, gonidis chroolepeis predito, apotheciis rotundatis — subdifformibus, 
fere mediocribus, in verrucas thallinas immersis ideoque quasi marginatis, hymenio su- 
perne epithecio fuligineo tecto, ascis late pyriformibus, sporis (sec. NYL.) oblongo- 
oviformibus, plerumque 6-cellularibus, 14—19 wu longis, 3—8 wu crassis. J intense
