Kaulfuss s.n. OU32768; counterpart (OU32768a) SEM stub (OU32768b), spores microscope slide (OU32768c)
Diagnosis
The new fossil is placed in the genus Davallia, due to the presence of at least 3–pinnate fronds with free veins; sub-terminal sori on veinlets with an abaxial extension of the ultimate veinlet along the indusium; elongate indusia attached by the base and sides; stalked sporangia; and annuli straight to curved, interrupted. The spores are ±oblong-reniform, bilateral, with a perispore and numerous, low, rounded verrucae, spreading ±radially from the laesura.
