More mushrooms

[ampersand55]

Is your feature request related to a problem? Please describe.

There are lots of berries and forest fruits that can be harvested, but not enough mushrooms. Mushrooms are a staple of foraging, but currently there are only generic mushroom and the morel.

See #78176.

Solution you would like.

I would like more mushrooms added to the game, both foraging mushrooms and some toxic/poisonous ones that could trip up a survivor.

Maybe also add some poisonous berries, like black nightshade berries, baneberries or winterberries.

The poisonous mushrooms can have the HIDDEN_POISON flag making them display as poisonous at >= 3 survival skill level.

Describe alternatives you have considered.

Additional context

I made a table of 10 mushrooms that are commonly foraged in New England:

Name	When to Harvest	Where They Grow	Can Be Confused With Poisonous Mushroom?	How Poisonous?
Oyster Mushrooms	Fall to early Spring	On decaying hardwoods like beech or oak	Yes, with Jack-O'-Lantern Mushroom (Omphalotus olearius)	Causes gastrointestinal distress; not fatal.
Chicken of the Woods	Late Summer to Fall	On dead or dying hardwoods (oak, cherry)	Rarely, if growing on toxic hosts like yew	Can absorb toxins from the host tree, leading to nausea and vomiting.
Hen of the Woods	Late Summer to Fall	At the base of hardwoods, especially oak	No	N/A
Chanterelles	Summer to Early Fall	On forest floors near hardwoods like oak or beech	Yes, with Jack-O'-Lantern Mushroom (Omphalotus spp.) or False Chanterelle	Jack-O'-Lantern causes severe gastrointestinal distress; False Chanterelle is mildly upsetting.
Black Trumpet	Summer to Fall	Leaf litter in deciduous forests	No	N/A
Lion's Mane	Late Summer to Fall	On decaying hardwood logs or stumps	No	N/A
Boletes	Summer to Fall	Near oaks, pines, or birches	Yes, with Satan’s Bolete (Boletus satanas) or other toxic boletes	Causes gastrointestinal distress; symptoms range from mild to severe.
Lobster Mushroom	Summer to Fall	On forest floors near hardwoods and conifers	No	N/A
Puffballs	Summer to Fall	Open fields, lawns, and forest floors	Yes, with immature Amanita mushrooms	Amanita species (e.g., Death Cap) are extremely toxic and can be fatal if misidentified.
Winecap	Spring to Fall	In mulched gardens, wood chips, or compost piles	Rarely, with some toxic brown-spored mushrooms	Can cause gastrointestinal distress if misidentified.

It should also be noted that the morel mushroom in the game can be confused with false morels, some of which are toxic such as Gyromitra esculenta

There are multiple technical issues that will prevent some of the proper implementation currently.

1. Harvest location: Underbrushes do not care at which location they are and making them spawn would only make sense as furniture, but that makes them not regrow. For more underbrush functionality, see #77288
2. Identification: There are no conditional names (#60196). Sure, making puffballs and those deadly amanita mushrooms both look like puffballs could work though. However, see below regarding the type of poison.
3. Harvest time: This is limited to seasons. No fine grained control. Only spring, summer, autumn and winter.
4. Type of poison: In order for them to show up as poisonous they need specific flags and this goes into a hardcoded poison effect. Have no gastrointestinal distress and thus entirely use vitamins, e.g for those amanita ones? No way to identify those as poisonous for the player. I played with that thought before and came to the conclusion that it might work using effect on conditions and transforming items but the solution is quite complex. You'd have e.g mushroom_puffball_unindentified and mushroom_deathcap_unindentified. These items are identical except for the deathcap having some fun extra vitamins. Using a a mushroom identification guide, an item doing effect on conditions, these can turn into mushroom_puffball and mushroom_deathcap when you use that guide. However, at low survival skill or maybe even a new proficiency you may fail to identify them correctly and a failure leads to e.g mushroom_deathcap_idfailed, being displayed exactly like an identified puffball but behaves like a deathcap. Then there are other circumstances to consider. What if you do not have an id guide? A spell could do but that is also kind of ugly. How about the item selection dialogue? I have no experience with that kind of eoc and it may or may not work.

Another thing complicating this is that if you have a rudimentary understanding of mushroom picking, you won't pick ones you're not sure you can identify, at least as to whether they're poisonous or not: there are some groups that have traits you can use, even if you don't know the exact species). Thus, you'd need some way of informing the player about the PC's level of certainty in identification in a way that doesn't rely on player knowledge.
