Apotheciis parcis lecta et earn ob causam defecte cognita. Apo- 

 thecium thallo immersum partibus internis supra descriptum est, 

 at apothecia substrato adnata nigricantia non examinavi. Ad 

 eandem speciem pertinere videntur. Sporae hie descriptae, quidem 

 numerosae a me visae, forsan non omnino maturae sunt et forsan 

 vetustiores magis similes iis Thelenellae muscorum.
