I've just collected Morchella from the Ascent and I have a query about the mushroom divines as she's my first.

Am I correct in thinking that the seasons that give the best skill gains are the same as the Plant Kingdom divines? If not and it's different seasons, does anyone have a list?

Not too worried about her gift but I'd like to try and maximise my work towards the mushroom divine trophy and don't want to waste straw if it's not the best season for earning skills from it.
