| Trichoglossum walteri |
| This earth tongue is covered with setae; bristle-like cells that provide protection to the spore producing cells. |
| See Mushrooms of Northeastern North America, Alan E. Bessette, et al., 1997, pp. 505-506 |
| The mature spores of Trichoglossum walteri are 60-125 microns long and are mostly 7 septate. |
| An ascus, blue tipped cell, lies below the protection of the large, pointed setae. (Melzer's mount.) |
| Most sources make clear that a microscope is required for accurate identification of Trichoglossum and Geoglossum species. Another critical requirement is fresh fruiting bodies from which to obtain a spore print. Spores obtained from a spore print provide mature spores that are needed for accurate spore measurement and septa count. |
