For consistency with other wood/fungus types

Wood follows the pattern:
Oak Log/Oak Wood

Fungus follows the pattern:
Warped Stem/Warped Hyphae

Poise is currently:
Poise Stem/Poise Wood

Should be:
Poise Stem/Poise Hyphae

This is known and would be somewhat nice for consistency, but it doesn't really make sense.
Poise is not technically a fungus nor necessarily a 'normal' tree.
