Observation 220185: Ganoderma P. Karst.

When: 2015-10-22

Collection location: Winchester, Illinois, USA [Click for map]

Who: Matthew Schink (MSchink)

No specimen available

Notes:
Two different Ganoderma species growing at the base of a single Oak tree, sent to me from Winchester Illinois. Specimen 140 is Ganoderma sessile, 141 is Ganoderma curtisii, confirmed by spore size and ornamentation.

Spore sizes

140: Me = 10.7 × 6 µm ; Qe = 1.8
141: Me = 9 × 5.9 µm ; Qe = 1.5

Specimen 140 has a “smooth” spore type, typical of members of the G.resinaceum complex, size is consistent with G.sessile.

Specimen 141 has a “rough” spore type, typical of G.lucidum,and G.lingzhi complexes. Spore size is consistent with G.curtisii.

Again. both species were growing on the same Oak tree.

I have found G.tsugae and G.applatum on a single log before, I also occasionally find G.applanatum growing alongside Fomes. I have seen people posting photos of two red Ganoderma species growing close together on the same wood, but this is the first time I managed to get a specimen to confirm via microscopy.

I find it quite interesting how two polypores can grow right next to each other sometimes only a few inches away, yet both seem to be functioning just well.

I just saw two Ganoderma species on the same tree for the first time recently in Portland, Maine.
