[1] Besides, his textbook on fungi called “Die pilze in morphologischer, physiologischer, biologischer und systematischer beziehung (Translation: The mushrooms in morphological, physiological, biological and systematic relationship)” in 1890 was also an outstanding work on the subject for many decades.

[4] In 1874, Wilhelm Zopf decided to leave his teaching position and turned into studying natural sciences at the University of Berlin.

[4] As Wilhelm Zopf obtained his degree, simultaneously, he also went back to Berlin as an adjunct professor teaching at the Agricultural College for a few years.

Likewise, he also published an authoritative fungal textbook in which he followed a classification similar in part to that of Julius Oscar Brefeld but placed Ascomycetes last in 1890.

In addition, he recognized the formation of ascogonia in many ascomycetes and even the union of these in Pyronema, with club-shaped “pollinodia”, but expressed doubt as to their real sexual function.

[8] In 1907, his book “Die Flechtenstoffe in chemischer, botanischer, pharmakologischer und technischer Beziehung (Translation: The lichen substances in chemical, botanical, pharmacological and technical relationship)” was published.
