At first, I thought this might be a puffball (see second-to-last picture). Then, when I saw it had a cap and stem with a veil and granules on the cap, I thought Shiitake (though they don't grow in the wild in North America). Then, I thought I might have an Agrocybe (until I saw that the spore print was white). So, I've settle on the Armillaria genus, perhaps a member of the Armillaria mellea group, following Arora's Mushrooms Demystified: "It is among the most variable and cosmopolitan of the fleshy fungi, and in its innumerable guises will confound you time and time again" (p. 196). These mushrooms had little black spots and hairs on the cap (typical of Honeys) and were quite variable in size, some having caps wider and stems longer than 10 cm. Some had rings or at least veil remnants. Some did not. They tended to widen toward the base; some were bulbous at the base (see first photo). The gills were typically close and sometimes decurrent, sometimes decurrent
The Deadly Galerina, Galerina marginata , might also be called Tripper's Bane because it bears close resemblance to some psychedelic mushrooms, but instead of psilocybin, it contains amatoxins, the same toxins found in many Amanita mushrooms. However nondescript this mushroom is, it's fairly easy to identify: it grows directly from wood; it can be found from the fall through early spring (sometimes year round). I almost always find it on fairly well-decayed wood that is covered in moss. It has a sticky cap (up to 4 cm across) that is typically convex. The gills are either attached or slightly decurrent. The stem is typically around 4 mm wide and a few centimeters long. It will usually have a ring or at least the remnants of a ring. The cap darkens red in KOH (see last picture) and the spore print is rusty brown, like the mushroom itself. This mushroom is also known as Galerina autumnalis .
