Observation 201833: Ganoderma P. Karst.

When: 2015-03-25

Collection location: Vancouver, British Columbia, Canada [Click for map]

Who: Matthew Schink (MSchink)

No specimen available

Specimen sent to me fresh from British Columbia. Apparently on cottonwood. Piece arrived moldy but I will attempt to culture it. I will add spore measurements later.

Context is white and with a rubbery texture very similar to fresh Piptoporus betulinus, perhaps a bit firmer. Microscopy reveals the white flesh to be dimitic or nearly so with skeletal hyphae being non existent or rare ( I saw maybe one).Skeletal hyphae can be seen clearly in the pore tubes. I will wait for it to dry to get some better tissue samples. Spore image included.

Pileus is brown, surface matching in appearance to G.applanatum. Cutis elements of the anamixodermis type indicating a relationship to the G.applanatum/adspersum clade (Subgenus Elfingia) Specimen distinctly different from G.oregonense which also has white flesh by the cutis.

Mature spores were unable to be isolated from the surface due to being entrapped in they hyphae of a contaminant mold so no measurements of mature spores can be included. Cutis is incredibly thick averaging between 1-2 mm.
