Thallus submembranaceus, parvus, punctiformis vel plus minus in 
substrato expansus, e cellulis pluristratosis (initio unistratosis) pseudo- 
parenchymalice cohaerentibus constitutus. Gellulae vegetativae rectangulares 
vel polygonae vel subsphaericae, in cytioplasmate chromatopliorum lami- 
niforme, parietale, luteo-vel aureo-fuscescens et guttas (granula ?) oleose 
nitentes includentes, membrana crassiuscula, achroa, subbomogenea prae- 
ditae. Membrana in mucum gelatinosum mutala, cellulae modo Syngene- 
ticearum in statum palmellaceum transeunt. 
Propagatio fit bipartitione cellularum in statu palmellaceo (zoogonidia 
nondum vidi).

Hab. in fontibus et rivulis, lapidibus, raro submersis plantis aquaticis 
adnatum una cum Ghantransia chalybea etc. Legi mense maio-junio in 
rivulis parvis inter saxa calcarea prope Solopisk et Korno et in saxis
