White mold? on King palms trunk.

[Panamajack]

Any ideas on what this could be? I just noticed this and did a little research. I think it might be an innocuous mold that usually grows in moist, fertile soils. But I'm afraid it might harm my palm. There is more in other areas around the garden, but this is the only palm that has it at the bottom of the trunk. I tried scraping it a bit but it's kind of hard so I just left it alone.

I have seen it on dead wood chips, so its probably saprophytic but a wood eater(hint: it could damage the outer dead wood on the palm's trunk).

I see its close to the roots as well. Are the roots touched by it healthy? If yes, its safe to say it doesn't like live tissues. But you still might need to do cultural amendment to avoid it eating on the trunk's wood

It does not seem to be a myccorhiza

I have seen this mold in Winter growing in shady and moist places, but always in the grass.

I am not sure if it is dangerous but you can clean it by hand and treat the area with peroxide hidrogen.

I concur.
