Mushrooms are tricky to grow. The actual organism, the mycelium, grows in secret, inside of logs, or
underground, invisible to our eyes until it suddenly fruits. Imagine if a tomato plant was invisible until the tomatoes suddenly appeared on the ground. How would you know when to water them? How would you know that bugs weren't killing the plants?
Your logs may be growing perfectly well, just waiting for the right conditions to fruit. Or the spawn may have died from heat and lack of moisture, and other fungi are now eating away at the logs. It's very difficult to tell what is going on!
Don't expect to be able to harvest mushrooms in the seasons when there aren't any wild ones growing. Mushrooms need a lot of moisture. Many of them only fruit during certain seasons, depending on the length of day. You need to keep them out of direct sunlight.
Chanterelles and several other edible species exist in symbiotic relationships with certain
trees and have so far eluded cultivation. Try and find some
local mushrooms that are saprophytic. Local mushrooms will be adapted to your climate. Mushroom spawn from a northern state will not have an easy time in the Texas climate. You might try joining a local mushroom club, if there are any in your area, as it's a good way to meet people with expert advice.
If you find a log with oysters or an other edible species growing on it, move that log to your garden or closer to your house so you can keep an eye on it.
I have successfully cloned wild oysters and grown them indoors under controlled conditions, but that is an involved process.
