Totally unsure of what this is, but it appeared to me to be too big to be a slime mold, but it was very, very small. This little mushroom grew out of the top of a quite dead and blackened Russula. There were multiple, unevenly spaced about an inch apart. iNaturalist is also confused! 🍄📷 📸🎞 🌿🌱 🟢 🍄‍🟫 🍄
