When: 2009-10-18

Collection location: Toronto, Ontario, Canada [Click for map]

Who: Toby Janssen (Toby Janssen)

No specimen available

I’d love to figure out exactly what these are. There were four different species of armillaria this fall and I can’t distinguish which is which. I managed to see them when they were young and some till almost grown . It seemed like some animal ate these mushrooms because they would get to a certain amount of growth then they would be destroyed. Most of the mushrooms would be gone and what was left was in shreds all over the place. I’ll post all four in separate entries. Three look like Armillaria Mellea but the species were distinctly different from each other.
