Fungi zyraogeni, unicellulares, hyphis genuinis destituti, gerami- 

 pari. Geraraula? (conidia?) ssepius catenulato-ramosae, continuae; asci 

 (raediis peculiaribus generati) subglobosi vel ellipsoidei, plerumque 

 1-4-spori; sporidia globulosa, rarissime subreniformia, continua, hya- 

 lina. — Generatio sexualis nulla. 



Obs. Fungilli praecipue in liquidis sacchariferis vigentes et fer- 

 mentationem alcoholicara efficientes. Status raetagenetici, praeeuntibus 

 cl. Loew, De Bary et Cuboni, species Cladosporii sistunt. Saccha- 

 romyces Mycoderma, observantibus de Seynes, Saccardo et Hansen, 

 sistit gradura vel statura e raediis peculiaribus ortura variarura Sac- 

 charomycetum specierum. Teste ipso Hansen sub eadera temperie 

 asci variarura specierura diverso teraporis spatio generantur; hinc 

 novum discriraen in speciebus determinandis.
