<jats:title>Abstract</jats:title><jats:p>Two new <jats:italic>N</jats:italic>‐glucosylated indole alkaloids were isolated from fruiting bodies of the basidiomycete <jats:italic>Cortinarius brunneus</jats:italic> (<jats:sc>Pers</jats:sc>.) <jats:sc>Fr</jats:sc>. The structures were elucidated by means of the spectroscopic data. Additionally, the very recently reported compounds <jats:italic>N‐</jats:italic>1<jats:italic>‐β‐</jats:italic>glucopyranosyl‐3‐(carboxymethyl)‐1<jats:italic>H</jats:italic>‐indole (<jats:bold>3</jats:bold>) and <jats:italic>N‐</jats:italic>1<jats:italic>‐β‐</jats:italic>glucopyranosyl‐3‐(2‐methoxy‐2‐oxoethyl)‐1<jats:italic>H</jats:italic>‐indole (<jats:bold>4</jats:bold>) could be detected. Compound <jats:bold>3</jats:bold> is the <jats:italic>N</jats:italic>‐glucoside of the plant‐growth regulator 1<jats:italic>H</jats:italic>‐indole‐3‐acetic acid (IAA), but, in contrast, it does not exhibit auxin‐like activity in an <jats:italic>Arabidopsis thaliana</jats:italic> tap root elongation assay.
