 Moser published Cortinarius Fr. und nahe verwandte Gattungen in Südamerika in 1975 , which was coauthored by Egon Horak . The work , along with his earlier monograph on " Phlegmacium " , proved to be some of Moser 's most important , serving to encourage others to engage with Cortinarius in a meaningful way . Cortinarius Fr. und nahe verwandte Gattungen in Südamerika was a study of Cortinarius , Dermocybe and Stephanopus , a new genus first described in that work , in South America , and was dedicated to Singer . The work contained descriptions of 276 new species . Alexander H. Smith stressed the significance of the work , saying " Anyone who has not worked in the systematics of Cortinarius cannot fully appreciate the magnitude and importance of this work to the general subject of the distribution and speciation of the higher fungi .
