1. https://en.wikipedia.org/wiki/Pleurotus_ostreatus - Oyster mushroom - common European edible mushroom.
2. https://en.wikipedia.org/wiki/Auricularia_auricula-judae -Jew's Ear- rare and delicious mushroom - used in salads and soups.
3. https://en.wikipedia.org/wiki/Fomes_fomentarius - Tinder Fungus - ancient known medicine for cough and bleeding, present days used to create mushroom spices.
4. https://en.wikipedia.org/wiki/Laetiporus_sulphureus - Chicken in the Woods - toxic but edible - i think it could be curiosity due it appearance.
5. https://en.wikipedia.org/wiki/Armillaria_mellea - Honey Fungus -ancient known edible mushroom - i guess could be fun if spawn on mirkwood logs and stumps.
6. https://en.wikipedia.org/wiki/Psilocybe_cyanescens - Wavy Caps - European type of Psilocybe - we have opium and hemp bud, new drug could be interesting - maybe it would give lp boost or ability to see some new curious like Opium Dragon?
Would be great addition if spawn of 3, 4 and 5 will damage tree quality by some points - i thought if this fungus quality will be same as tree, each spawn damage about 5% of total q, but never goes below 10q. Sort of decaying mechanic for abandoned tree farms.
Another idea is new type of farming for mushrooms, separated from Garden Pots to a new substrate blocks made from Mulch and Mirkwood? (well noone actually grow shrooms in pot - not sure it is actually possible..) Also if 3(Tinder Fungus) will be a spice it definitly should be fabricated some way, like any other spices in-game.
P.S. And ofcorse we need Mushroom stockpile
