 1883, [). oG5, t. XVIII. — Fornia cndophytica sub plantx' niatricis 

 stroniatibus nidulante, e cellulis viridibus, globosis, singulis vol 

 gregariis (tuuc e mutua pressione polyhedricis), composita; cellulis 

 niaturis ad 27 a. diam., membrana crassa, lequali cinctis, con- 

 tentu Ia3to viridi, granulis minutis, guttulis ha3matochromaticis et 

 nucleo amylaceo instructo; nucleo cellulari in ceUulis adultis fa- 

 cile conspicuo; tbrnia epiphytica in planta) matricis superricie ubi- 

 que extante, stigeoclonioidea; tilamentis hinc inde in discos coalitis, 

 marginibus filiformibus erectis; cellulis vegetativis 5,4 s; 4, reclangu- 

 laribus, rotundatis vel (in partem interiorem disci parenchymatici) 

 polyhedricis; membrana tenuissima, haud gelatinosa, plasmate ho- 

 mogeneo, dilute viridi, nucleo amylaceo distincto, dein guttulis, 

 ha3matochromaticis immixto.
