Observation 211719: Ganoderma sessile Murrill
When: 2015-07-30
No herbarium specimen

Notes: Ganoderma on a healthy dogwood? I almost went for it. But a closer look at the soil beneath the tree indicates that the dogwood is planted in the buried stump of an old (probably) maple! Oh well..,

Three fruitings surrounding the tree…hmmm, the soil is bare in the same circle.

This agrees with my own observations on Ganoderma in North America.

I do

There are several possible species within the resinaceum complex in North America, and if I am not convinced it is G.sessile I will mark it as G.resinaceum group.

They are all closely related and share the traits of being typically sessile in nature, having a “smooth” type spore, and bleeding a yellow liquid when the white edge is cut or damaged.

Okay, thanks!

I noticed you have quite a few observations with G.resinaceum attached to them!

Yes

G.sessile in an American variant of the European mushroom G.resinaceum, DNA confirms the two are distinct. I will provide a source later.

as I mentioned above. Dogwood is growing in the middle of the stump.

I got the lecture from Caz last month, so I know how to look for truffles. I have seen evidence nearby but not at this location. I will check again soon.

my knowledge of dogwood mycorrhizae. Unlikely the terre brule associated with dogwood, Other nearby trees? Possible host trees can be 30-50 feet away.

indicate possible terre brule, or burnt earth, indicative of truffles like Tuber lyonii, Tuber melanosporum, and others, Martin. Search these out for future (or current) truffle production. Also search for animal digs nearby.
