Field Guide to the Lichens of Great Smoky Mountains National Park (Tripp & Lendemer 2020) took 12 years to write, but is finally in print and available on amazon.com (https://www.amazon.com/Field-Guide-Lichens-Mountains-National/dp/1621905144/ref=sr_1_1?crid=3AKEHEJFN8SKM&dchild=1&keywords=field+guide+to+the+lichens+of+great+smoky+mountains+national+park&qid=1586900589&sprefix=field+guide+to+the+lichens+of+great+%2Caps%2C200&sr=8-1) as well from the University of Tennessee Press!

The Lichen Biome (EBIO 4560 / 5560) is being offered fully online this Maymester (2020)… check it out in the course catalogue!

Professor Tripp & PhD Candidate Sharples are teaching Colorado Field Botany this summer, 2019… check it out here!

A successful field trip to Grape Creek (upper Arkansas River Watershed, Colorado) with our Fall Plant Systematics course, just in time to beat the snow! We spent an entire day keying 30+ species of plants and had a blast! Our favorite? It MIGHT have been Pectis angustifolia… complete with glands bearing lemon-scented ethereal oils!

We welcome a new member to the Tripp lab, Jeff Rose, who is joining us as a postdoc from the University of Wisconsin-Madison!

Check out the Lichen Biome class this Maymester!

Lichens are biologically diverse hubs of interactions, and The Lichen Biome course will cover numerous dimensions of diversity within this symbiosis (algae, bacteria, fungi, and ecological and evolutionary relationships therein) and beyond it (diversity of lichen symbioses in nature, their ecological functions, and conservation). Through student-led experiments to be initiated and finished during the course, students will develop and apply core skills relating to understanding of the biology and development of lichen symbioses and their roles in the environment.

We wished the hustler of Ruellia bioinformatics, Yongbin Zhuang, good-bye as he returned to China to continue his research at a local university.

Here we all are out at the Rayback Collective to show our appreciation and thanks to YB as he begins this new phase of his career:




Students & Others: The Tripp Lab is a SAFE SPACE for everyone of all races, genders, sexual orientations, cultures, ages, nationalities, religions, abilities, and political viewpoints. HELP FIGHT DISCRIMINATION – lend an ear and learn to respect what you don’t understand!

I am proud to work with colleagues who similarly advocate for human rights for all! See the following:





Welcome to a research lab at the University of Colorado, Boulder, with broad interests in the evolution of biodiversity on Earth. We specialize in macroevolutionary patterns and underlying processes describing plant and lichen biodiversity, but celebrate all research in biology… the science of life! …And endless forms most beautiful…

  1. I’m a Buff from the seventies who studied under Drs Marr, Shushan, and Ives among others. Spent a lot of time tracking lichens in the mountains. If you find new lichen species in CO, please consider naming one after Sam Shushan. He was a CU lichen pioneer. You should have seen his offices in the towers of Hale. Specimens to the ceiling.

    Good luck. Go Buffs!


    • Hi Jeff – tonight I was getting together some lichen specimens to donate to the U of Oregon’s museum when Sam Shushan’s name popped into my mind. He gave me a couple of specimens back in 1952 or 1953 that are going to a good home here along with a few I collected. It was a pleasant surprise to find his name on google so quickly, although disappointing he is no longer alive. It was fun to see Dr. Marr’s name, too. I worked for his Institute of Arctic and Alpine Ecology in its formative days.
