Name that lichen species! (There's a special prize for every right answer, and a darn good one at that).

Name as many as you can!

Guess which is the lichen

This one of my favorites

That's why I love you Steve. Weird, but quite enjoybable. Man, I wish I could frame this page and send it to everyone I know. You crack me up.

Well, in the first picture, I’m guessing that the black spots are actually fruiting bodies of lichen fungus. The orange-ish lichen body in the far right of the picture is Porpidia flavocaerulescens.

As for the second picture, the lichen is the mint green-ish body resting in the middle of the picture. I believe that is Xanthoparmelia chlorochroa. This commonly found in desert conditions and doesn’t actually attach to a substrate. I’ve heard that the Navajo use it to cure impetigo.

The chimney like or tubular lichens in the bottom picture are probably apothecia on a foliose lichen. Either that or it is a Thelomma californicum (otherwise known as the “lobed nipple lichen”).

I really hope I win the prize. Is it an all-expense paid trip for six to the sunny climes of Orem, Utah???

Derek I think you just made someone's day!

Holy smokes! Derek is good. I knew the Bar Exam was pretty comprehensive, but I had know idea. Anyway, not to ruin the fun but question number two has been answered by brother Derek. Picture two is Xanthoparmelia chlorochroa or tumbleweed lichen. Not only used to treat najavo impetigo, but also to dye wool. It is in fact an unattached or "vagrant lichen" and one of the key players in my research. Although Porpidia flavocaerulescens is not present in the first photo, the black spot are in fact fruiting bodies (correctly called 'apothecia'. The third picture does in fact represent a foliose lichen with apothecia. However, it is not the lobed nipple lichen. In short, Derek rocks! Plus he has an awesome prize coming his way (perhaps he'll be coming our way). Still two prizes left. Don't give up.

I think the top one is called "Golgatha"(or place of the skull), the second is "flora" because it looks like flowers and the bottom one is called "boogies".

Starkeys win prize number two! Although Gogatha and Flora would be appropriate names, only boogies is the right answer(not named after the 'boogies' that initially come to mind, but Jack Cass Boogie, the first lichenologist in the west. Congratulations!

Wally's has a prize coming his way for at least knowing some terminology associated with lichens.
