I have 2 or 3 types of mushrooms growing in the mulch around my orange tree near Houston, Texas (UDSA Zone 9a). What are they? The the last picture is actually 3 clustered, I haven't pulled it up yet because the bugs on it.
All these appear to be growing out of soil which has a quite woody, fibrous mulch - which is where the mycelium have come from, and these are the fruiting bodies. I'm by no means even vaguely a mycologist, but the penultimate and last pictures may be Macrolepiota rhacodes, Shaggy Parasol - they start out one shape and end up another, and the white gills beneath become tinged with red as it ages. They may not be that at all, perhaps someone else can give a definite ID, so I wouldn't recommend you eat them without being 100% sure. You also mention something growing out of your lawn, but I see no lawn in the pics.
