    Moss murdered by mushrooms

    Hey folks, generally I always say "no sweat" when anyone asks about shrooms growing in their potting mix or planted vivarium, as it hasn't been a problem in the past as the mycellium burns itself out after whatever it's feeding on is exhausted. However, in this particular instance what the mycellium was feeding on was my beautiful live moss, not peat or orchid bark which is already "dead". So now the moss in several of my pots is totally dead & yellow - still puffy but not green and growing. Will it come back if I leave it alone and just keep flushing it or should I swap it out with new moss? I really hate to move the plants since they've only been potted for a few months at most but it looks so crappy compared to the pots of live moss.

    One positive aspect of the shrooms is that it seems to have kick started my U. humboldtii which began putting up numerous leaves after sitting there looking bored for a year or so!

    I had that happen in a heli-pot - the sphagnum moss just barely survived and still looks crispy 2+ months later

    SIG,
    LOL Nope, they're just any number of common LBMs I guess.

    Thez,
    The moss isn't crispy (thankfully) it's still puffy but blonde / brown but not growing anymore and not looking great. Gonna try a light fertilizer flush on the "weird" pots and see if the moss greens back up, glad it's only about 3-4 small pots that I can see so far.

    I had no idea sphagnum could sustain mushroom life - I assumed sphagnum was pretty nutrient devoid. Generally I get it in fresh orchid bark (around the 2-6 month mark) but this was in the sphagnum, whether it sprang up from the live sphagnum or the dead Chilean stuff I'm using as a moisture base in the HL chamber I couldn't say. I pulled out all the mycellium infested moss I could find in hopes of stemming the tide.

    I'd leave the moss and give it a chance to grow back. Generally the sphagnum spores are far more resilient to conditions than they are given credit . . .

    I noticed something like that happened to my sphagnum once temps heated/changed. But eventually the moss came back. Its only if you start noticing algae or slime on the moss, you can think about removing it.

    Mine also get mushrooms. I suspect that it's the dead lower sections that support the growth. Most of the LFS in my tanks grows well with or without the fungi but I've had a 2 tanks where the moss died soon after I placed it in the tank and those 2 tanks (out of about 10 or so) never grew any LFS again. (although the very bane of my existence - liverworts - liked the conditions & thrived).
    All the best,
    Ron

    Temps aren't raising even though it's summer. The HL chamber is controlled by a Zoomed Hygrotherm to stay 75*F days and 50*F nights with 95% RH. Otherwise my apartment is very warm, LL plants in an enclosure damn near grow themselves.

    What I did notice on my fertilizer flush tonight is in the 3 most affected pots with absolutely "no" green sphagnum (2 x N. inermis and a dubia) is some other strain of moss is still green so the mushrooms only went for the sphagnum totally ignoring this other species (makes it easy to pluck out the strands of non-sphagnum). I will leave them for a while and see if the sphagnum rebounds, since it's not crispy just blond looking as if I'd used dried.

    Ron,
    I hope I don't get the no-live moss curse, now that I have good crops of it growing I love the stuff! Gonna start a new bin of live moss tonight actually...
