 formantia nigras, nudas, opacas. Perithecium fuscum, glo- 

 bosum, integrum, lat. circ. O.oso — O.090 mm („0.i — O.2 mm" 

 observante Nyl.), basi nutrici immersum, margine ostiolari

Perithecium impellucidum, e stratis nonnullis cellularum 

 formatum, ostiolo rotundato aut irregulari. Nucleus albidus, 

 haud resinoso-guttulosus, jodo dilutissime caerulescens deindeque

 medio haud constrictae. — Sec. Nyl. „huc accedere videtur 

 Thelidium sordidum Th. Fr. (Bot. Notis. 1866 p. 16), sed nomen 

 sordidum vix decens habendum sit" (quod autem scientiae magno-
