A positive reaction of Schaeffer's test, which uses the reaction of aniline and nitric acid on the surface of the mushroom, is indicated by an orange to red color; it is characteristic of species in the section Flavescentes. The compounds responsible for the reaction were named schaefferal A and B to honor Schäffer. [3]

A cystidium (pl.: cystidia) is a relatively large cell found on the sporocarp of a basidiomycete (for example, on the surface of a mushroom gill), often between clusters of basidia. Since cystidia have highly varied and distinct shapes that are often unique to a particular species or genus, they are a useful micromorphological characteristic in ...
A 2008 molecular phylogenetic study clarified the relationships among the mushroom-forming species of the family. [15] The authors demonstrated the existence of four distinct lineages of gilled mushrooms, which led to the description of Multifurca as a new genus separated from Russula [15] and the segregation of Lactifluus from Lactarius. [16] [17]
During his teaching process, Stuntz would collect almost every group of fungi he could find and try to identify it. He would write his own keys to his collections and a few of them were eventually published. One of his important publications was a book named How to identify mushrooms to Genus IV: keys to families and Genera, published in 1977.
