As of 1.3, RimWorld has Devilstrand be the only mushroom that grows in the light.
This cannot stand.
----
This mod patches devilstrand to be renamed devilflax and produce devillinen instead, without touching any stats. It should work with any devilstrand patches, though it won't alter their textures or names or anything to reflect the change from devilstrand to devilflax.
Devilflax texture is from Textiles+, taken with permission by the guy maintaining it: https://steamcommunity.com/sharedfiles/filedetails/?id=2095650910
