Earth tongues
Most sources make clear that a microscope is required for
accurate identification of Trichoglossum and Geoglossum
species, commonly known as earth tongues.  
Another critical requirement is mature fruiting bodies
from which to obtain a spore print.  Spores obtained from these
collections will provide fully developed spores that are needed for
accurate spore measurement and septa count.  Found in late summer
and fall growing from soil. Although sometimes found in semi-open
woods, grassy and mossy
areas are usual haunts.
