Possible Trich Contamination on second flush?

Hi!
I recently harvested the first flush of Mazatapec's from a Grow Kit.
Today, I noticed what seems like dots of denser white mycelium on the surface of the substrate and also a bit on the sides.
I think this could be Trich in the early stages, but I'd like to hear your opinion before throwing the kit away.
I have to add that the first flush seemed perfectly healthy, except for a weird smell on some of the fruits, something that reminded me of amonia but not exactly.
Here's a picture of how it looks right now:

Thank you

If your mushrooms smelled like ammonia, they're spoiled, throw them away.

Thanks for the quick reply. Are you sure they're spoiled? They looked fine:

Yeah they look ok to me. I don’t know of every possible ailment of mushrooms but I’ve seen some horrendously contaminated grows (and done some) that produced perfectly safe mushrooms.
If there was something else growing on/in them or they’re rotting and obviously gross then... But I’d eat those.
I don’t see any trich there but that picture is kinda hard to see clearly.

Ok, thank you! So, have you had mushrooms with that kind of smell and still eaten them?
Yes, the picture isn't very good indeed lol if you look closely you can see what seems like small white cotton circles on some spots of the substrate (top right and bottom right for example).

I’ve never had an ammonia smell as far as I remember.
I just did some reading, maybe Th e same thing that guy up there read. It said if they smell like ammonia they’re spoiled and toss them, but that was an article about how to tell if your fresh mushrooms have gone bad over time. Yours are just grown so they have definitely not spoiled in the fridge.
You can only use your judgment based on how serious and strong the smell is, and if anything really looks off about them up close. Definitely dry them fully, I wouldn’t eat them fresh in this case. Maybe give them a rinse before the dehydrator, and then check them out once dry for any weird smells.

My dad is a very experienced mushroom hunter, specializing in porcini. Even those that are clearly rotting from within are used for drying out and using in soups and sauces. I don't think you have anything to worry about.

Thank you guys, I appreciate your help.
This is how they looked before putting them in the freezer:

As you said, I don't think they have gone bad over time, but I'm worried about the smell indicating some kind of nasty bacteria that could be harmful.
I guess I'll have to decide if I'm going to risk it or not lol They're cracker dry and in the freezer now and I was going to make tea with them, so if I decide to consume them I hope all that will have killed any possible bacteria.

Are the dots you’re talking about knots?

I don't know, maybe they are, but it looks different from what happened during the first flush.
Here's a picture where I've highlighted the dots. Sorry for the bad quality:

Thank you!
This is how it's looking today. I tried to highlight the spots where it's easier to see.
It seems more abundant than yesterday, but still completely white, not greenish.
The grow kit instructions reccomend leaving the bag slightly open while it's fruiting. Is this a good idea or would it increase the risk of contamination?

Thank you both!
It's actually a bit "whiter" than the rest of the mycelium, but it's been almost a week since I saw it for the first time and it hasn't grown much, is still white and no weird smells, so I guess it wasn't trichoderma

You can see some trich here near the hole where I had cut the first spot out.

The very edge where it’s bright white is what it looks like at first then goes green after. But it is very fast none of it was even there a day and a half before.

Ahh I see, it's a bit different, indeed. Less cottony and more like some powdered white substance maybe?
I find it really difficult to distinguish healthy mycelium from contaminants. Whenever someone posts a picture I'm thinking: it all looks the same to me lol.

I thought the same thing until I had my first trich show up.
You’ll know when you see it.
