A rachis of the fossil filicalean fern Botryopteris antiqua containing abundant septate hyphae with
clamp connections is preserved in a late Visean (Mississippian; *330 Ma) chert from Esnost (Autun Basin) in
central France. Largely unbranched tubular hyphae pass
from cell to cell, but may sometimes produce a branch
from a clamp connection. Other clamp-bearing hyphae
occur clustered in individual cells or small groups of
adjacent host cells. These hyphae may be tubular, catenulate
with numerous hyphal swellings, or they may display a
combination of both. The Visean hyphae with clamp connections
predate Palaeancistrus martinii, the heretofore
oldest direct fossil evidence of Basidiomycota, by some 25 Ma.
