note that there are at least two if not three or four different tastes that can be attributed to any given species depending on fresh or dry, age, spore content...
when i have the opportunity to sample fresh rain-soaked wild-grown Ps. cyanescens here in the pacific northwest, the taste is mild, slightly bitter and astringent, with very little aftertaste. (just thinking about the juicy little buggers makes me salivate... reminds me of smell and feeling of fall rains)... goes well with ranch dressing or on pizza.
i haven't had an opportunity to sample fresh home-grown Ps. cubensis, but I imagine the taste would be even milder than cyanescens due to the fleshier nature of the mushroom (compared to the slightly fibrous woodlover)
dried cyanescens and cubensis have a similar "dirt" flavor that sticks to your mouth. my brother says that vending-machine Tropicana orange juice has been ruined for him due to one time when he used it for a powdered cubensis smoothie.
i've read a lot about home growers choosing to harvest their cubensis right before the veils break, as any later than this and the fungus is simply putting effort into the maturation of spores. and spores are reputed to taste absolutely terrible.
