Uromyces ari-triphylliAs you can see from the list below, Schweinitz published on plants as well as fungi, and when he died, his herbarium contained 23,000 species of phanerogamic plants. And they weren't his main interest! Schweinitz is sort of a transitional figure in mycology, as his first major publication is before Fries, while his second is after. It would be interesting to see what proportion of his new names come from each work. In any case, he is the first major American mycologist, by a long shot - - both in time and in quality. Many of our "basic" American fungi were named by him.
