Redwood mushrooms

Last year while I was visiting my family for Christmas we went hiking around Muir woods, a redwood forest. I took pictures of a lot of mushrooms because I think they look cool. It had rained almost the whole day the day before, so there were tons of them everywhere! 

Now that I'm getting more into mushroom identification, I wish I could have spent more time examining these mushrooms. Most little brown mushrooms (LBMs) are difficult to tell apart and not really worth trying to identify, at least for a novice. Here's some photos.

whatever this is, it looked like melted cheese

maybe a brown cap

shelflike fungi on trees are usually Polyphores, which decay wood

perhaps some sort of puffball
