Which images are lichens? Numbers 2 and 5.
- #2 is a “jelly lichen,” or cyanolichen. The presence of cyanobacteria (blue-green algae) and lack of stratified structure (usually) gives them a gelatinous texture compared to most foliose lichens.
- #5 is a foliose lichen, probably a species of Peltigera or Sticta.
Which images are fungi? Numbers 1 and 4.
- #1: Dead man’s fingers, the fungus Clavaria (Alloclavaria) purpurea, a great Halloween fungus.
- #4: This is a species of Helvella, possible H. lacunosa.
Which images are mosses? Number 7.
Which images are “algae”? Numbers 6 and 8.
- #6: One growth form of the free-living cyanobacteria Nostoc. This genus is a very common photobiont in cyanolichens.
- #8: These colorful marine algae, aka seaweeds, are from the U.S. Pacific Coast.
Which images are none of the above? (and what could they be?)
Number 3 is a liverwort! This is the thalloid form of these bryophytes, probably Marchantia or a similar genus.
Extra credit: Which one does not grow in Colorado?
Number 8 shows California seaweeds, and Colorado currently lacks coastal environments.
