We've had a lot of rain these past few days, especially. I suspect that's the main "incentive" to cause fungi to grow... but I can't identify these. Thanks for your help! The first one (small, white, round) was only about 1" or so in diameter. The second was about 3" in length. The third was a little larger. The fourth... is it a fungi? The ends were only about 1/3 - 1/2" (no more) in diameter.
The second picture could be Tremella concrescens, a jelly fungus that often grows on the stems of herbaceous plants.
The first could certainly be Tremella concrescens. I've looked it up a bit and it seems to fit. Thank you! I'm not sure about the third being "chicken of the woods." It doesn't quite seem to fit, as it wasn't growing on a tree. It was rather rubbery looking and it was on the ground... but I'll keep looking, too. Thanks!
