Fungicidal 1-aminomethyl-3-(2-fluoro-3-chlorophenyl)-4-cyano-pyrrole derivatives of the formula ##STR1## in which R stands for a ##STR2## wherein R.sup.1 stands for optionally substituted alkyl, for alkenyl, alkinyl or cycloalkyl, or for in each case optionally substituted aralkyl or aryl, R.sup.2 stands for in each case optionally substituted heterocyclylalkyl, heterocyclylalkenyl, heterocyclylalkinyl or heterocyclyl, for dialkylaminoalkyl or for in each case optionally substituted cycloalkylalkyl or phenethyl, R.sup.3 stands for hydrogen or alkyl and R.sup.4 stands for cyano, alkanoyl, alkoxycarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, for alkylsulphinyl, for alkylsulphonyl, for phenylsulphinyl or for phenylsulphonyl. The compound where R is replaced by an election-withdrawing leaving group is a novel intermediate.
