Maiaspora panopta D.A.Mamontov, D.McLean, O.A.Orlova et O.A.Gavrilova

Original diagnosis/description

Spores radial, trilete, acavate, azonate. Amb triangular with straight or concave sides, rounded apices. Laesura straight with delicate labra, three-quarters or four-fifths of the spore radius in length. Exospore is relatively thin. Proximal and distal surfaces are covered by biform sculpture with a reticulum decorated by apiculate elements (verrucae, coni, tuberculae) to produce a metareticuloid sculpture. Muri are low, slightly sinuous and clearly tapered at the top, more or less triangular in vertical cross-section. Lumina are polygonal. Distinct, circular or elliptical scrobiculae occur at the bases of the lumina and open as vertical, funnel-like tunnels (Fig. 5).


From Maia, a beautiful mountain nymph of ancient Greek mythology. The genus is dedicated to Professor Maia V. Oshurkova who made major contributions to Soviet and Russian Palaeozoic palynology and palaeobotany.
