A lot of great research has come out of Lutzoni’s lab. Congrats on the poster.

Thanks Jason! I thought it was that, but wasn’t sure.

By the way, I got an summer undergraduate research assistantship working in Dr. Lutzoni’s lab at Duke University!

I also got 4th place out of 30 at the SE regional poster convention for my lichen research, and am in the process of finishing my paper. (PS – you’re mentioned in the acknowledgements)

Three choices in North America I think

P. perforatum – norstictic acid alone (UV- K+)
P. preferforatum – norstictic + alectoronic acid (UV+ K+)
P. subrigidum – norstictic + stictic acid (UV- K+)
P. rigidum – alectoronic acid alone (UV+ K-) – but not in N. Amer.?

It’s a joke, isn’t it?
