Question 1

Is Ganoderma sessile the same as G. lucidum?

Accepted Answer

No, G. sessile is a distinct North American species, though it was historically often misidentified as G. lucidum. Phylogenetic analysis has confirmed it as a separate species in the G. curtisii/G. sessile lineage.

Question 2

Why is G. sessile important for supplement production?

Accepted Answer

Cultivation studies have shown that G. sessile grows better in controlled settings and produces more polysaccharides than both G. sichuanense and G. oregonense, making it a particularly promising species for commercial supplement production.

Question 3

How does G. sessile differ from G. tsugae?

Accepted Answer

G. sessile grows primarily on hardwood trees in eastern North America, while G. tsugae grows on conifers (especially hemlock) in the Northeast. Phylogenetically, they belong to different lineages within the Ganoderma genus.
