Thallus humidus est magis obscuratus, quia pars inferior 

 aut interdum interior obscuratus est. Thallus totus plectenparen- 

 chymaticus, leptodermaticus, gonidiis usque ad superficiem repansis 

 aut partim in superficie strato gonidiis destituto O.012 — O.020 mm 

 crasso, cavitatibus cellularum anguloso-rotundatis, O.004 — O.003 mm 

 latis, seriebus cellularum verticalibus. Gonidia globosa diam. 

 O.ooe — O.005 mm, ellipsoidea long. O.010, lat. O.006 mm, in intersti- 

 tiis hypharum verticalium disposita, ita ut cavitatibus cellularum 

 parenchymaticarum inclusa apparent, tantum simplicia visa, flavo- 

 virescentia, membrana in microscopio a me adhibito haud aut 

 interdum bene conspicua. Thallus in specimine in Simo lecto 

 (f. robiginosa) plus minusve intense robiginoso-rufescens, in alio 

 specimine tantum zona robiginosa in strato medullari albido. 

 Perithecium plectenparenchymaticum, cellulis brevibus, ellipsoideis 

 aut rotundatis, cavitatibus O.003 — O.004 mm latis, membranis leviter 

 vel modice incrassatis, fuscofuligineis, conglutinatis. Periphyses 

 long. circ. O.020, crass. O.0015 mm. Paraphyses in gelatinam 

 diffluxae, tubulis tenuissimis, distinctis. Asci clavati aut 

 oblongi, membrana gelatinosa, modice incrassata. Nucleus 

 jodo dilute violascens. Sporae 8:nae, distichae, simplices, de- 

 colores.
