I have six pots with plants. I noticed on one of the pots something starting growing on top and I’m not sure what it is.
It appears to be mushrooms, fruiting bodies from a fungal organism growing in the organic matter. It is not likely to be pathogenic/harmful, just opportunistic and part of the decomposition process
Hot temps and a lot of water with blossom rot on tomatoes - treated with fertilizer, yet I have spots of this nasty looking fungi in the soil as well as in the wine barrel planters.
This often happens in containers and can easily be corrected.

It's a type of fungus. There are many different kinds of large, strange shaped fungi that come out after a rain. Often you see these sea-creature like fungi affixed to tree trunks. Here is an example:

We had sod put in our backyard a month ago and now have mushrooms popping up a lot. Otherwise it looks good. Of course, we have been watering it a lot since it is new. Should we do anything about the mushrooms?
Here are tips to remove them, or you can leave them alone - they are beneficial.

Can you grow Porcini from Dried Porcini mushrooms ? And if so how would you do it ?
These grow symbiotically on living trees and so are not commercially grown. They are harvested from the wild. You can grow other mushrooms though:

I did a deep dive to find an answer and it is No. Dried porcini is highly unlikely to contain live spores and mushrooms can not be grown from "cuttings". However, the spores are available online. Good luck.
I noted a large crop of these mushrooms after a few days rain. They were in a nearby field under an oak. They smell like standard mushrooms, have brown gills, and white flesh. They do not bruise yellow. Do you think they are safe to cook and eat?
I would not advise eating anything wild. There are too many toxic look-alikes. Especially in the case of mushrooms.
