Evidence of fossil Peronosporomycetes has
been slow to accumulate. In this review various fossils
historically assigned to the Peronosporomycetes are
discussed briefly and an explanation is provided as to
why the fossil record of this group has remained
inconsistent. In recent years there have been several
new reports of fossil peronosporomycetes based on
structurally preserved oogonium-antheridium complexes
from Devonian and Carboniferous rocks that
demonstrate the existence of these organisms as
fossils and refute the long-standing assumption that
they are too delicate to be preserved. Among these
are several types characterized by oogonial surface
ornamentation patterns not seen in any modern
members of the group. To date at least three groups
of fossil vascular plants (i.e. lycophytes, ferns and seed
ferns) are known to host peronosporomycetes as
endophytes; however only one form has been
identified as a parasite.
