Protist both microbial eukaryotes and macroscopic organisms that do not fit into the other traditional kingdoms. In cladistic systems (classifications based on common ancestry), there are no equivalents to the taxa Protista or Protoctista, both terms referring to a paraphyletic group that spans the entire eukaryotic tree of life. In cladistic classification, the contents of Protista are distributed among various "supergroups" (SAR, such as protozoa and some algae, Archaeplastida, such as land plants and some algae, Excavata, which are a group of unicellular organisms, and Opisthokonta, such as animals and fungi, etc.). "Protista", <nowiki>"Protoctista"</nowiki> and "Protozoa" are considered obsolete. However, the

Only nine genera of fungi are recognised in the book: "Agaricus", "Boletus", "Hydnum", "Phallus", "Helvella", "Peziza", "Clavaria", "Lycoperdon", and "Mucor" (listed on page 645); a tenth fungal genus, "Tremella" is covered, but included among his algae. "Scottish Fungi" note that "While his classification might be a bit wonky by today's understanding, most of the species he recorded can be traced to modern taxa", and that he provided the first British records for the chanterelle and the summer truffle. The book has an "English and Scotch Index of the Names of
