corophilic mushroom id help

Can someone give me a first impression on what they think these might be? Normally, I would check my field guide or Myco keys then when i think i know what I have, I do some reserach and make sure my specimnes exhibit all the correct traits and which traits their poisonous look alikes exhibit. This time, however, I cant find any hints in my field guide or Myco keys.

Both of these were found on horse dung.

The first has free or adnexd gills (it is difficult to tell since the stem is so thin) and a spore print that is the same color as the gills. The stem is hollow. Everything ele you can tell from the picture.

The second has a black spore print and adnexed gills. It shows all of the traits of a certain phycoactive mushroom (the name escapes me right now) except the stem does not have spinning fibers running up the stem and it doesnt bruise blue.

What are your first impressions? Give me something to start on so I can research these and see what I have. Pretty please?

woops. This is the first specimine. The other one is the second specimine.

In general, I don't try to ID little brown mushrooms (LBM's) because they're so difficult and the consequences are so severe.

Yeah, I'm with John,

I don't know very many of them and they've yet to take priority. I will get to them though.

I can say that I have defiantly seen those things growing all over the place and that they are not any variety of edible or hallucinogenic mushroom that I know of. And those are both things I have done a fair bit of ID on. They're super cool though, if kinda inauspicious. Pay attention to um' and let us know if you find out what they be!

The first pictures seem to be of a Mycena, which one I don't know.

The second pictures could be another form of Mycena or a species of Marasmius

I have several of both species growing on the farm but since they are inedible I just leave them alone, they are pretty to look at.
