Tremelloscypha Gelatinosa, A Species of a New Family Sebacinaceae

ABSTRACT

Eichleriella gelatinosa Murrill, known only from the type locality in Jamaica and from Florida, is transferred to Tremelloscypha on the basis of its coriaceous, flabellate to infundibuliform basidiocarps, the relatively thick-walled, brownish hyphae lacking clamps in the trama, and the ovate to pyriform basidia lacking basal clamps. A new family, Sebacinaceae, is proposed to include Tremelloscypha, Sebacina s. str., and Tremellodendron. It is suggested that Efibulobasidium be tentatively assigned to the Sebacinaceae. This arrangement brings together several taxa that possess similar basidial and hyphal characters but whose basidiocarps vary from pustulate or incrusting to erect and branching or flabellate through infundibuliform.
