1. Diphyscium foliosum

This small plant is widespread in eastern North America. Dr. Schofield collected and kindly donated specimens to Biology 321.

Here is a cross-section through a vegetative leaf; it is bistratose.

Here are some antheridial plants.

A closer look.

You can see some antheridia within the perigonial leaves. I am surprised that noone saw these in lab....

This is a close-up of a young female plant. The operculum is still intact.

A perichaetial leaf has a unistratose blade and a long costa that extends from the apex of the leaf as an awn.

The upper margin of the perichaetial leaf is jagged.

Here are some older sporophytes. You can see the white cone-like peristome.

Nose to the dirt... Note the antheridial plants...and a lone sporangium.

2. Buxbaumia piperi

This specimen was found along Tatlow Trail at Stanley Park.

It matured very slowly. About six months after the initial siting it had reached this stage.

A close-up of the sporangium:
