In this post I mentioned that the soil in my schefflera plant's pot had been host to some yellowish fungus, but I somehow managed to misidentify some discolored perlite as the fungus in question.
However, I rediscovered the fungus yesterday; here a small growth can be seen about an inch in front of the base of the schefflera: And here is a closeup of the same:
Then, when I was watering my philodendron, I discovered what appears to me to be a very similar, fuzzy yellow fungus on the surface of its soil as well: And:
It doesn't really look quite like the dog vomit slime mold discussed here.
I removed the schefflera soil's strange cylindrical growth with a toothpick easily enough; but is this fungus something about which I should be concerned, or will simply scraping it off whenever it appears keep the problem at bay? Should I repot the schefflera and philodendron in new soil? Water less often? Or is it beneficial, and OK to leave as is?
