MYXOTRICHUM Kunze - Sacc. Syll. IV, p. 317. — Genus ex ele- 

 mentis variis compositura, ad interim hic servatuin. Primus monui 

 (1881) species quasdam hujus generis vesiculis suboctosporis pol- 

 lere, hinc principio ad Mucoraceas, demum vero et rectius ad Gy- 

 mnoascaceas referendas esse putavi (Gfr. Syll. IV, p. 317 et VIII, 

 p. 812 et 823). Nonnullae vero species ascis destitutse sunt et ad 

 Hyphomyceteas spectant. Qua de causa necessarium videtur pri- 

 stinum genus in duo divellere; nempe: I. Myxotrichum Kunze 

 ascis prasditum e Gymnoascaceis (M. coprogenum, M. chartarum, 

 M. ceruginosum etc); II. Myxotrichella Sacc. ascis destituta et 

 ad Hyphomyceteas partinens {M. spelcea, M. murorum, M. ra- 

 ra etc).
