Hi Ariani, thank you for posting, It is hard to tell from the photos some of the details needed for identification. Also you are in a region far from mine, so some of your local fungi will be different from those I am familiar with. Here is a link to the page listing Identification Tools, which describes details that are useful to have when trying to ID: http://www.botanicalgarden.ubc.ca/forums/showthread.php?t=44106 The details that are most significant vary between fungi groups. The tops of the caps in your first photo remind me of some east coast polypores that I'm not familiar with. Is this growing from wood, can you tell? Does the underside of each "cap" show a smooth surface, or tiny pores, or gills, or something else? Your fourth photo might be either a cute little inky cap group member (Coprinus and related), or maybe a Lepiota. In this case, the spore colour would be helpful. Can you tell if white or black spores are coming from the underside of the cap? For photos two and three, more info is needed such as hard or soft, has it been there long, is it growing from soil or wood, etc. Hope that helps, cheers, frog
The third one is between the concrete blocks. The first one on the photo are like Agaricales. The second one is similar (or it looks like) with teh third one. Thank you Frog for your explanations.
