Fungal Examples of Convergent Evolution: Lichen Evolved on Two Tracks, Like Marsupials and Mammals (click through for article)
_____
"A Duke research team has found that lichen that seem identical in all  outward appearances and produce the same internal chemicals are in fact  two different species, one living in North America and one in  Australia. They’re an example of "convergent evolution," in which two  species evolve separately but end up looking very similar, like the  Tasmanian wolf and the American wolf.
The lichens developed the same adaptations to survive and thrive in  vastly different regions of the world. Since they show the same  evolutionary patterns as marsupials and mammals, but are easier to  study, they could become model organisms to further probe how mammals  and other groups of organisms evolve, said Duke biologist Brendan  Hodkinson…”
