Remarks (internal):This species is very easy to distinguish by the presence of a black inner context layer of the sporophores. Only Phellodon niger (Fr.) P. Karst., not found in Florida, can be confused with P. alboniger. They both have the black hard inner context layer; however, P. alboniger can be distinguished from P. niger by the presence of the white tomentum at the active growing margins of the pilei which become grayish brown at the discs. The tomentum of P. niger is white at the margin becoming olive gray to darker gray at the disc (Baird, 1984).
