Howdy folks.
It's been noted in the thread here that Alder is suitable for the cultivation of a number of species of culinary mushroom (you can put Hericium species on that list also) -- but I thought I would add that Alder chips are considered the substrate par excellence for the outdoor cultivation of several wood-loving species of the genus Psilocybe. Including Psilocybe cyanescens, Psilocybe azurescens, and a few others.
... in case that's of interest to anyone here, for medicinal purposes against anxiety and depression (for which there is a growing body of efficacy evidence).
