What is this on my mushroom???

I can't really tell....for one the photo is blurred and lacks detail......for another the dang thing is so HUGE its a distraction.
But.....best I can tell it may be expelling waste.......or it may be a reaction to stress and/or disturbance. Either way I've seem them react in that manner and be fine as a peach in a few days time.
...just a side note.....the threads flow much better and photo attachments are less of a distraction if they are smaller in size.

OK that you nm form now on ill just post the link to the pics if thats ok. That way they can still be big enough yet make it so you dont have to scroll across the screen. Also today it looks more like the first pic. Much less of the pink stuff and also is all the way out like the others. Thanks again!!!
