Omnia ut in planta typica, sed hypotheciura aequaliter obscure 

 fuscum et crassura, sporae magnitudine ed septatione cougruentes, prae- 

 sertim autem reactione J provocata diversa, hae reagente nee hymenium 

 nee ascis distinete coloratis, dum in planta typica paraphyses semper 

 persistenter eoerulescunt et asci plus minus rosee colorantur. Apothecia 

 in toto irregulariter rotundata, explanata et variantia ut in planta typica. 

 Varietates e forma apotheciorum sumptae pauci sunt momenti.
