Observation 11194: Agaricomycetes Doweld

When: 2008-09-15

Collection location: Forest near Elgin St., Pembroke, Ontario, Canada [Click for map]

Who: Paul Derbyshire (Twizzler)

No specimen available

These were almost buried. It’s a mystery how the spores were supposed to be dispersed, unless they will push up further as they mature.

I’ve uprooted one here and you can’t really see any gills, suggesting a partial veil and immature mushroom.

In mixed woods.

I did return to the area where I saw these a few days later, but didn’t find either of them, not even the one I hadn’t disturbed.

Need to get cross-section of this one, Paul. It may be something like Macowanites or Brauniella, which never releases its spores to the air. It is fascinating to some of us because these fungi have evolved a close symbiotic relationship with animals and insects. In this instance, the mushroom would need to be eaten by a vole (a kind of mouse) or a slug. The spores would pass through the digestive system unharmed, and be excreted some distance away in an ideal growing medium. In the case of voles, the animal cecum also combines yeast propagules with the spores. Some hypogeous fungi, such as truffles, may not germinate without an exudate of those yeast propagules.

But back to identification: still need to see whether there were gills or pores, and the only way to do that is to slice the specimen in half. That would also allow any color changes of the flesh to be noted, which can also be important to identification, as in the Gastroboletus family.
