Femoral artery is most common after vascular catheterization. A hodgepodge of organisms.

Mycotic anerysms

A complication of septic emboli in endocarditis, it is rare in the modern era and is due to what ever is causing the endocarditis. It is, of course, not fungal, but Osler thought they grossly they looked like a mushroom. Or maybe Osler was eating mushrooms at the time.
