Odor – Kinda sweet, fungoid, smelled rather good.

Taste – Like a watered down mushroom, slightly sweet.

I thought that Agrocybe sp. had tough stems, the majority of these were silky white and brittle. I am not doubting you Alan, just trying to learn about some mushrooms I have never encountered before.

I have been hunting over some of the same areas for the last 5 years, I want to observe how the fungi that grow in these areas change as time goes on. I have seen some fungi grow for 2-3 years, then new mushrooms seem to take over. Is there any information regarding how mushrooms in a certain habitat change as time goes on? As food sources for some species of fungi disappeared it seemed like others would come in and finish up what the “first wave” did not finish, does that make sense?

It is Agrocybe

Due to the look of the gills, spore print color, and habitat. But mostly the look of the gills. Check the odor/taste.

Please explain why you think this is an Agrocybe sp., in detail if you can.

Hmmm, I guess I would not have thought Agrocybe sp. because of the brittle stipe. The only specimens which had “fairly” tough stems were the youngest specimens.

Also confusing is the range of spore color from what I have read in numerous field guides and online sources the spore color can range from: brown, black, dark purple/black, dark purple/brown, and dark purlple/gray.
