On a very old/mature Sambucus nigra, 76 cm in diameter!; edge of back road, protected from the afternoon sun. The fungi are growing from the thick base upwards. They presented themselves with different sizes. Biggest cap was 9 cm in diameter. Cap is wrinkled; few days later some caps were cracked. The gills have a fascinating smell of a mix of edible mushroom and chocolate! No staining or bruising was seen. Spore print is of rusty/chocolate tone.
