 In 1956 , while still a researcher at the Federal Institute , Moser began lecturing on microbiology at the University of Innsbruck , with the title of " Privatdozent " . During this time , he continued to publish . His monograph on the genus <unk> , a taxon now considered to be part of Cortinarius , was published in 1960 as part of Die <unk> <unk> series . Unlike the previous three books in the series , which were all written by German authors , the work addressed mushrooms that were of less interest to amateur mycologists ; for instance , the genus was not considered to contain any significant edible species . The book drew upon Moser 's expertise concerning mycorrhizal relationships . It listed 166 species , including some " exotic " taxa . Some of the listed species were described for the first time in that volume . The illustrations , which came in the form of a number of coloured plates , were mostly Moser 's own work ; Singer described these in a review of the book as " both in original execution and reproduction among the best that have been published " . Discussing the book as a whole , Singer said that the volume , " outstanding for its good print , attractive appearance , and interesting contents , should be present in every mycological library " .
