Lycoperdon nigrescens

Lycoperdon nigrescens, with the synonym lycoperdon foetida, commonly known as the dusky puffball, is a type of puffball mushroom in the genus "Lycoperdon". It was first described scientifically in 1794 by the Swedish naturalist Göran Wahlenberg. Visually similar to other species when young, it grows increasingly darker with age, and lacks the pronounced stipe that old lycoperdon perlatum attain.
