20 S. ALMQUIST, MONOGRAPHIA ARTHONIARUM SCANDINAVLAZ. 
A sequenti his precipue notis differt: apothecia ochraceo-pruinata, spor maju- 
sculce 4-cellulares, grana hymenii KOH non solvuntur, sed vinose rubent. Preterea hyphee 
et gonidia KOH et J violascunt; asci circa 45 u longi, 22 uw crassi, spore 15—18 u 
longae, 7—8 mu crasse. — Hab. in Europa saltem media, varios cortices (presertim 
fagi) incolens. 
Obs. 1. .Sp.elegans AcH., ex Helvetia a ScHLrICHER missum, certe hec est species. 
Tria a nobis visa spec. Achariana, ex quibus uni »ex Helvetia» inscripsit ipse auctor, ad 
unguem quadrant in descriptionem sat extensam in L. U., excepto, quod mirabile dictu 
apothecia dicuntur coccinea. MouG. NEsTtL. exs. 470, determinatum secundum spec. a 
SCHLEICHER missum, idem testificat. 
Obs. 2. Hane a sequenti non specie differre nonnulli contenderunt, graves tamen 
note suadent; discernat, cui in natura eas observandi facultas erit.]

Thallus limtitatus, tenuisstmus, sepe hypophleodes, gonidus chroolepeis; apothecia 
forma et magmitudine varia, plus minus pruinosa, trita rufofusca; asci solito angu- 
stiores, obovati; spore Magne, vulgo I-cellulares, cellula suprema ceteris multo majore; 
hymenium J ccerulescens, KOH plus minus intense violascens. 
Thallus hypophleodes vel epiphleodes farinaceus, e cinnabarino albidus vel 
rufescens vel cinerascens. Hyphe sat tenues, maxime intricate monilia gonidiorum 
mox disrumpunt, frustula eorum vel singula gonidia arctissime cingentes; KOH et J 
leviter vel interdum vix conspicue cerulescunt vel violascunt. Gonidia sat parva, KOH 
et J non vel levissime roseole tinceta. Nonnumquam vidimus immixtas cellulas corti- 
cales destructas, totas vel partim KOH et J intense violascentes (incorrupte lutescentes). 
Apothecia valde varia: in f. Scanica fere minuta (circa 0,> m.m. diametro), ap- 
pressa, orbicularia, disco albido-, margine cinnabarmo-pruinosa, trita et intus obscure 
fusca; in f. Norvegica submagna (usque ad 1,5 m.m. diam.), innata, eleganter stellato- 
divisa, fere epruinosa fusca; inter has extremas omnes fere intermedize forme adsunt. 
Hypothecium confluens cum hymenio subincolori, in cinnabarinum vergenti, sursum
