Summary:
Features include growth flat on wood with the typically pale grayish pore surface exposed, separability, small pores, and microscopic characters including allantoid to cylindric spores and large skeletal hyphae which become gelatinized in KOH. The description is derived from Gilbertson(1) except where indicated.

Odor:
faint, unpleasant (Buczacki)

Taste:
indistinct, (Buczacki)

Microscopic:
spores 5-7 x 1.5-2 microns, allantoid [curved sausage-shaped] to cylindric, inamyloid, colorless, thin-walled; basidia 15-20 x 4-6 microns, clavate; cystidia none but "fusoid, non-projecting cystidioles occur scattered among the basidia"; hyphal system trimitic: generative hyphae 3-5.5 microns wide, colorless, with clamp connections, skeletal hyphae 3-8 microns wide, straight to sinuous, thick-walled to solid, "gelatinized in KOH and disappearing, weakly amyloid, most easily seen in hyphal masses", binding hyphae apparently rare, 2-4 microns wide, thin and richly branched, observed only in context, (Gilbertson), skeletal hyphae in some fruitbodies weakly amyloid and in others dextrinoid, (Ginns)

Spore Deposit:
white (Buczacki)

Notes:
Diplomitoporus lindbladii has been found in BC, WA, OR, ID, AB, NF, AZ, CA, CO, LA, MA, MN, MS, MT, NM, NY, SC, TX, and WI, and it is circumpolar in the coniferous zone, [so presumably in Europe and Asia], (Gilbertson).
