467–470.
R e m a r k s. Only one spore of this taxon was
found in the studied material in the Lusatian
seam. Morphologically, it is similar to spores
of the recent Dennstaedtiaceae, especially to
genus Paesia. This taxon represents cosmopolitan
(P/A) climatic element, and occurs
in Europe in the Middle Eocene to Miocene
fossil palynofl oras. It was also reported from
the Lower and Middle Miocene of central and
western Poland.
Dennstaedtiaceae (16 genera) occur worldwide
in tropical to temperate areas. Paesia
is distributed in tropical South and Middle
America, Malaysia and Pacifi c Islands (Stuchlik
et al. 2001).

1967 Perinomonoletes pliocaenicus n. sp., Krutzsch,

Spores monolete, bilateral, 45–50 × 25–30
μm in size. Laesura poorly visible. Exine 1.0–
1.5 μm thick. Perine smooth, waved, protruding
up to 3.5 μm from exine surface.

R e m a r k s. Several spores resembling in
structure Perinomonoletes pliocaenicus, but
more than 55 μm long, nearest the fossil taxon
P. goersbachensis were found.

Spores similar in structure to Perinomonoletes
pliocaenicus, 32–55 μm long. Perine with
delicate “spines”.

Spores similar to the above-mentioned ones,
but perine thin, very delicate, protruding up to
a dozen or so μm from exine surface.
R e m a r k s. Spores of the morphological genus
Perinomonoletes approach those of recent
members of Polypodiaceae s.l.; particularly
Aspleniaceae, Blechnaceae and Aspidiaceae
(Nayar & Devi 1964a–c, Kremp & Kawasaki
1972), and the genera Asplenium L., Athyrium
Roth, Bolbitis Schott, Byrsopteris Morton,
Cornopteris Nakai, Ctenitis C. Chr., Cyclosorum
Link, Diplazium Sw., Dryopteris Adans.,
Egenolfi a Schott, Lastrea Bory, Lithostegia
Ching, Peranema Don., and Polystichum Roth
( Krutzsch 1967, Thiele-Pfeiffer 1980). They
were reported from the Eocene and Pliocene
(Krutzsch 1967), as well the Miocene deposits
of Germany (Thiele-Pfeiffer 1980) and Hungary
(Nagy 1985). In the analysed material
they occurred only in two samples from the
Komorniki profi le.

R e m a r k s. Spores of this taxon are slightly
similar to those of the recent families Cyatheaceae,
Dipteridaceae, Pteridaceae and Lygodiaceae.
They represent palaeotropical/warmtemperate
element (P/A1), and occur in Europe
in the Lower – Middle Miocene. They were also
found in the Upper Oligocene to Lower Pliocene
deposits in south-western Poland (Stuchlik
et al. 2001). In the studied material only
one spore was found in the Mużaków series.
