@toolate Some good ideas in there, but a few problems as well.

• Firstly, normal myconids aren’t blind, so it would be a bit weird to make the player version break that trend.
• Secondly, the complete inability to speak verbally is very harmful to non-spellcasting characters since they would be unable to access the telepathy that would be needed to communicate.
• Finally, although fey ancestry makes sense in some campaign settings, the Myconid people are usually portrayed (as far as I am aware) as being from the Underdark, not the Feywild

All that being said, most of this criticism really only applies to officially published materials, meaning that everything I just said goes out the window if you plan on using this in a custom or modified campaign setting.
