The iNaturalist.org map tab could help you determine whether it has been found in your area. [0]

I was hoping it had not made it to Texas since it was reported mostly in the NE US but it looks like some people have started cultivating it here and it may have escaped cultivation sometime during the last few years.

Considering that it is an invasive fungus that is known to degrade all the natives in the area it should be no surprise that the questions about whether the fungus was found growing on a grow block are rarely or never answered in the Texas reports. This could be due to the questions being asked by researchers trying to identify spread mechanisms from posts that are several years old. The original poster may not respond either because they don't remember or they are not as active as they used to be.

I think there are 8 reports in the state today and at least one is obviously in a grow medium of sawdust. [1] The fact that people placed most of their sitings on parks instead of home gardens when more than one case clearly shows a residential setting may suggest that they are growing something that they know can escape but they would like others to think they found it in the wild so it isn't their problem.

I have a great natural environment for them with several live oak widowmakers standing dead for around 25 years. I have not seen any yellow mushrooms though, yet. I think the native mulch industry in Texas will probably be their main spread vector since hardwoods are mulched locally and sold all over the state. As far as I know there are fewer restrictions on mulch sales from infected areas than there are on firewood sales across county lines. I think mulch may incorrectly be classified as compost in this case where the assumption is that there has been large scale degradation sterilization of weed seeds, fungal spores, etc due to decomposition temperatures.
