Mushrooms growing in my orchids

Hi I live in S. Florida and we have gotten days of rain here with more expected in the next few days. So this morning I went to check out my orchids and to my horror I found mushrooms growing in several of my phalanopsis orchids. I know that mushrooms have fungi spores and now I am concerned about fungus. Should I spray with a fungicide or I have heard of using hydrogen peroxide or is that just for crown rot?. Any suggestions !! Or is it okay to just pull out the mushrooms?? Is there anything all natural or do I need to spray chemicals?

I'm not sure if the mushrooms would introduce any pathogens to your plants, but they feed off the bark and will hasten its decomposition. I would gently remove them. Others will be able to advise you on chemical treatments.

The mushroom fungi might actually out-compete any other kind of fungi... Which would be good, cause it would not allow the bad fungi to coexist in the pot with the mushrooms, or your orchid... That is my guess... Please just ignore my comment if no one agrees with my assumption! Lol

I've had some occasional mushrooms pop up in pots and on mounts. They've never caused any issues but when they sprout on a wood mount its usually a sign that the wood has broken down considerably.

Well I have pulled out the mushrooms. I did not want to take any chances of inviting fungus on my orchids. Hopefully the sun will be back out and get things dried out. Thanks for the comments!

The bits you can see are only the fruiting bodies, the fungi will still be present and digesting the bark, as someone mentioned time for a repot soon.

I agree. The bark will be full of mycelium which will continue consume. It will damage the roots considerably. I think you should drench the roots in chlorothalonil or similar and repot into fresh bark.

Probably means the medium is past fresh. Time to repot.
