I wouldn't recommend anyone here look for Gyms unless they have prior knowledge/experience when it comes to identifying mushrooms. At the very least get them ID'd on a forum, for example the shroomery.
I've picked G spectabilis (/ G junionus) and know that those were inactive, or EXTREMELY weakly active, despite being positively ID'd as the correct mushroom by me and forum members.
I know that they are more often active in the far east however, and that occasionally they bruise green - although not always.
