dimidia parte emersa, deplanate globosa, sepe radiatim striatula, 
fusca v. subnigricantia usque ad 0,7”—8 m.m. lata. Paraphyses 
hymenii disciformis urceolati c. 0,06 m.m. alti capillares, laxe 
cohzerentes, hyaline. Spore 8:ne, oblong&, qvadriloculares, pal- 
hide, 0,010—12 m.m. lone&, 0,005—6 m.m. late. Gelatina 
strati qvam maxime supremi hymenii jodo levissime (zgre di- 
stingvendum) primum czerulescens, hymenii ceteri unacum ma- 
turis sporis rufescens v. juvenilis flavescens. 
Hab. in Alten Finmarki@ ad thallum sterilem praeique so- 
redia Parmeli® hyperopte v. ad qvisqvilias thallinas alias. Qvam- 
vis hec & pracedens species parasite sunt, tamen qvoad fa- 
bricam apothecii graviorem cum Limboris tam congruunt, ut 
quum ex hac ratione tum propter reactionem jodicam hymenii 
ad lichenes nec ad fungillos numerand& sint. In specie utraqve 
adest jam ante dehiscentiam vacuum spatium lenticulare inter 
superficiem hymenii & verticem perithecii. Constructio apothecii 
ut hymenium discocarpeum in perithecio pyrenocarpeo apparet. 
Stratum superficiale hymenii jodo a catero differentes reagens 
indolem peculiarem sc. epithecialem prodere videtur. In Z. 
corrosa hymenium totum jodo cerulescit, in L. actinostoma & 
Eugeana flavescit, thallo ex adverso passim intense czerulescente. 
Medium inter has tenet reactio jodica specierum parasiticarum.
