SPECIES, AUTHORITY P. keralensis Ramanujam & Srisailam 1980, p. 129, pl. 2, fig. 26.
LOCATION Cannanore beach area, Palayangadi and Cheruvattur (southern side of Karingottu River), Kerala State, India; locality: Palayangadi.
ORIG DESCRIPTION* Spores dark brown, aseptate, elliptical to somewhat rhomboidal, 25.5-30.6 x 8.5-15.3 µm, multiporate, 3-6 equatorial pores, not always equidistant, often showing zig-zag alignment, rounded to slightly ovoid or even transversely elongated, 3 µm in diameter, pore margin prominently thickened (2.2 µm), spore wall 1.7 µm thick, surface scabrate, locally coarsely so.
COMMENTS* The spore wall of this species is scabrate, unlike the psilate wall of the type species. Common in the Palayangadi samples. P. keralensis shows significant resemblance to the ascospores of Amphisphaerella dispersella (Eriksson, 1966).
