Abstract:
Before the application of molecular techniques, evolutionary relationships between sequestrate genera and their epigeous counterparts in the Russulaceae were unclear. Based on overwhelming evidence now available, personal observations, and consideration of the International Code for Nomenclature of Algae, Fungi and Plants, we combine the overlapping sequestrate generic names Bucholtzia, Cystangium, Elasmomyces, Gymnomyces, Macowanites, and Martellia with the agaricoid genus Russula. This nomenclatural action follows precedents set by earlier mycologists and continues an effort to create clarity in our understanding of the evolutionary affiliations among sequestrate fungi - particularly the Russulaceae. We also provide the first comprehensive list of described sequestrate species of Russula.

For disubstituted benzene derivatives, with two groups attached to the benzene ring, three constitutional isomers are possible. For example, consider dimethyl benzene, often called xylene, where the second methyl group can be substituted at the second, third, or fourth carbon. The relative position of the substituents is represented by prefixes ortho, meta, or...
