I went on a foray looking for mushrooms and noticed this. It’s a hump in the duff, right in the middle of the photo.
It’s hard to see what might be in there! I went around to the other side of this shrump (a hump in the duff where a mushroom is emerging).
That looks pretty exciting. I cleared away some of the debris to see better what was in there.
Aha! It’s Hypomyces lactifluorum, also called the Lobster Mushroom. It’s so fascinating: this is a parasitic mold attacking another mushroom. The original mushroom is Russula brevipes (Short Stemmed Russula) which although edible, is rather bland and crumbly. H. lactiflulorum attacks and parasitizes it, causing it to become dense and firm. They are often quite large.
