These Blackwoods will have you STUMPed with a FUNGI sitting just beside one if them nestled in leaves and foilage. Container opens like a clamshell (think mouth-guard case) and Jimmy Geo-Pooch has given his paw of approval. Please open carefully (do not pull on the FUN-GI) and close so that it is sealed to prevent moisture entering. Log Book and swaps. BYO pen. This can be a high muggle area at times so be discreet. I think a swap hopped out while I was replacing the original container, so if found nearby, please take home and look after it or place back in the container for the next person.
