From p. 89: "Die jetzige Ansicht des Dozenten geht also dahin, dass die Flechten nicht selbstständige Pflanzen, sondern Pilze in Verbindung mit Algen seien, welch' letztere der erstern Nährpflanze bilden." (The present view of the docent [viz, Schwendener] is thus that lichens are not independent plants, but are fungi [which live] in a relationship with algae, which latter constitute food plants for the former.)
