This one macroscopically resembles some Agaricus with a ring detached ( remnants are seen on photos). It would be helpful to provide your questions on fungal identification with any information on the habitats and substrates of your species, not only the locality. It`ll help to get more useful and accurate answers because this data are necessary for species identification at near all cases.
I just like to add to Elena suggestions that the scale bar is also needed to identify the fruit body. Or at least the information about its size. The micrographs such as basidiospores (say, from the sporeprint) or a part of hymenium may be also helpful.
For now I suggest Lepiota genus or maybe Agaricus as Elena suggests. Although no one can be sure with the lack of any additional information.
