Microscopy is consistent with Murril’s original description of G.sessile.As well as the published description in Taxonomy of Ganoderma from southern South America- subgenus Ganoderma. with the exception of the spores. I measured mine from the inner spore wall as I see that as being more consistent, because the outer wall is prone to damage. So my spore measurments are slightly smaller.

Smooth type spores, numerous faint echinulations. Space between spore walls is thin.

Proposed Names

13% (4)
Recognized by sight: G. tsugae if on conifers. According to M. Kuo: " This beautiful mushroom is closely related to Ganoderma lucidum and is virtually indistinguishable from that species on the basis of physical features alone. However, Ganoderma tsugae is partial to conifers—especially eastern hemlock."

Nice long list of spore measurements.

Microscopic measurments added.

Measurments of cutis elements as well as spores added. Matching description of G.sessile.

Also included is a photo of the resulting mushroom grown from a culture obtained from the conk in the second photo.

Returning to observation location this November no signs of any new fruiting could be found. About a quarter mile away two lone specimens were found Obs#192970.

Technically two

Different observations, one is slightly down the street from the other. One was growing out of a buried maple stump, the other is growing from someones planter. (A barrel cut in half) I have both, as well as a third collection in culture.

1 or 2 ?

Does this post have two different observations in it? One outside and a different mushroom inside? Or is it the same mycelia mass fruiting on two sides of a wall?

Confirmed as Ganoderma sessile by microscopic features(Taxonomy of Ganoderma from southern South America:subgenus Ganoderma). Cutis cells match that of the holotype for G.sessile. All macro morphological features are also a match for G.sessile. G.sessile also falls within the G.resinaceum group, this is backed by DNA evidence.

you need microscopy to identify Ganoderma…
