Shaggy Mane Sequence

I was going through some fall photos for a report I am working on and came across this sequence of mushroom pictures.  This particular mushroom is a shaggy mane. Good to eat only when new and then it proceeds to turn into what looks like blobs of ink. The ink blobs are full of spores.

I am not a mushroom expert and have limited my mushroom picking to very few mushrooms. Any good mushroom book will cause some pause unless you develop a lot of confidence. But mushrooms are a part of the western Washington landscape that has inspired a culture of mushroom connoisseurs. New shaggy manes are eatable before they turn into unappetizing blobs of ink.
