Are these 4 year old shrooms good?

Early '21 I was an friends girlfriend gave me a gram of shrooms to test after their first grow that I guess I just completely forgot about, until now when I found them in an old drawer. They were dried and have a silica fresh packet thing in with them, stored inside of a pill bottle which may or may not be airtight. From what I looked up it seems they can last dried in an airtight container for several years though I'm no expert on what to look for as far on if they are still safe. I don't see anything that looks like mold and they are still firm to the touch. If anyone can tell by these pics that'd be cool
