Deer Fern Spore Under the Microscope

Deer Fern Spore

This plane of focus is about midway through the spore. The perine is optically active as can be seen by the light color of the perine film layer outside the endospore. In Deer fern the perine is thicker at the base of the spore and forms a skirt.

Transmitted Oblique Off Circular Polarized Light Illumination


Deer Fern, Blechnum spicant, is found in moist, maritime Northwest forests of North America and occasionally inland.
