Original Description

Outer cortical shell smooth, very different from the inner; in the outer the two principal cupolas are larger than the two lateral; in the inner inversely smaller. Pores subregular, circular, in the outer shell four times, in the inner shell twice as broad as the bars; ten to twelve pores in the basal semicircle of one cupola.

Major axis (length) of the outer cortical shell 150µm, minor (breadth) 130µ; pores 12µm, bars 3µm; major axis (length) of the inner cortical shell 110µm, minor axis (breadth) 90µm; pores 6µm, bars 3µm.

Etymology:
Latin alternatus -a -um = alternate
