title: Russula parvovirescens sp. nov., a common but ignored species in the eastern United States.
abstract: Russula parvovirescens sp. nov. is described from the eastern United States. It is a rather common species that previously was mistaken for a small R. virescens or a green form of R. crustosa. The large and characteristic extremities that compose the pileipellis allow easy identification with the microscope or even with a good hand lens. The new species is described here, illustrated in detail and compared with R. virescens and R. crustosa.
