ok thanks for clearing that up, I realized they looked like em but for some reason thought they were an ingredient as well.

Alternaria is responsible for many allergies in the summer and fall because of some specific antigenic proteins found on the spore surface. The “mold count” you hear about consists largely of Alternaria spores.

My medical mycology students are doing mushroomobserver pages for importation into the encyyclopedia of life. see eol.org for some examples. The pages are all drafts now, but will go “live” in a few weeks.

Oh, and the cookies were made by a student to be Alternaria-shaped for a poster on this fungus. :)

Oh yeah, and what hideous disease do these beauties produce?

I suspect the cookies are not flavored by, so much as mimicing the shape of, this wonderfully distinctive microscopic form; Alternaria alternata shaped cookie-cutters, as it were.

interesting, you can make cookies from brown spot on leafs?
how does that work? is any particular plant better for making cookies?
does it have a recognized medical or culinary/taste value?
