Abstract

Genetic relationships for several species of the fungusOmphalotus were estimated by comparing the presence or absence of restriction sites in the ITS1-5.8S-ITS2 region of nuclear ribosomal DNA. Results placeO. olearius, O. subilludens andO. olivascens in a single clade.Omphalotus illudens, usually thought to be related toO. subilludens, was placed in a second clade, more closely related toO. nidiformis. Omphalotus mexicana is distinct from all other examinedOmphalotus species.
