 In 1963 , Moser published a second work in the Kleine Kryptogamenﬂora von Mitteleuropa series , Ascomyceten ( Schlauchpilze ) . This work was a monograph on the Ascomycetes , focussing on the Discomycetes . Though not as well known as his earlier book , it was well received in the mycological community . The mycologist Richard Korf , reviewing the work in an article published in Mycologia , said that " the book belongs on the shelf of every mycological library in Europe " , praising the " [ e ] xcellent , workable keys to the orders , families , genera , and European species " . Korf wrote that , " [ i ] f a single fault can be found , it is surely the lack of documentation provided " . However , a combination of a lack of time and Moser 's comparative lack of expertise in Ascomycetes prevented subsequent editions of the work .
