ARCANGELIA Sacc. (Etym. a cl. botanico ilalico J. Arcangeli, in 
Universitate Pisana Botanices professore)— Perithecia frondibus vi- 
vis (Hepaticarum),immersa, subglobosa, membranacea, hyphis præ- 
longis remotis conspersa, nigricantia, ostiolo rotundo vix papillato 
pertusa. Asci cylindracei, octospori. Sporidia didyma, hyalina. 
Paraphyses distinctæ, ramulosæ. ; 
Obs. — À gen. Lizonia differt peritheciis immersis, membrana- 
ceis, sporidiis achrois ; a gen. Didymella perithecüs biogenis, longe 
piligeris ; a gen. Stigmatea demum perithectis longe piligeris, para- 
physibus copiosis, ramulosis. Gen. Lizonia, olim uti aparaphysatum 
descriptum, teste cl. Pirotta in N. G. bot. ital. 1889, p. 317, para- 
physes genuinas gerit.
