Nina Zidak is a student at MSU-Bozeman. She is studying houndstongue (see pictures above). When we went on our field trip to Bozeman, she took us to the Plant Growth Center and showed us her green house room where she grows her project plants. Her project plants were houndstongue. She would spray the plants with a fungus and she would see which plants would grow best or die first after they'd been sprayed. After they were sprayed, they would turn to a whitish color. She then took us to her lab room and showed us some more of her expiremements. She is studying a bacteria in a petri dish. It looked weird under the microscope. She also showed us some cottonwood leaves that she had to identify the fungis that was on them. It is killing the leaves and the tree. The fungis was a redish color, almost like rust colors. She didn't say where the tree was located or what she thought the type of fungis was. Houndstongues scientific name is Cynoglossum officinale. Houndstongue grows in ranges, pastures, and along roads. Houndstongue was introduced from Europe. The leaves are reddish-purple in color.
