Reader Kirk Gentalen shared this photo, snapped in the woods of Mid-Coast Maine after a rainy day in early fall. What is this?
Answer
This is a hare’s foot inky cap mushroom (Coprinopsis lagopus) near the end of its deliquescence – a process in which the mushroom self-destructs by producing enzymes that liquify its cap and gills, which results in the release of spores. “Inky caps are famous for deliquescing,” said Kirk. “What you are seeing in the photo is the space between the gills, because the gills are gone/have liquified.” For more information about this mushroom, check out this write up on MushroomExpert.com by Michael Kuo or this United Kingdom-based Mushroom Diary.
