Anyone who be given a garden has belike seen all sorts of mushrooms pop up over time on their mulch , lawn , or garden beds , particularly after a good rain .
And while they can sometimes be concerning if you have curious pets or children , mushrooms are actually a good sign of level-headed soil because they feed on decaying plant matter and wrench that into nutrient - rich humous . So , mushrooms think all variety of undecomposed matter happening in your territory !
Here in Central Oregon , we had an unusually wet springtime followed by a blazing hot summertime that call off for more frequent watering . I ended up with a miscellany of mushrooms grow alongside my plants : doll ’s nest fungi , loving cup kingdom Fungi , Conocybes , and many more that I ’ve never identified .

But what stopped me in my tracks one day was something quite out of the ordinary : a chunky , xanthous - white blob on my straw mulch that looked like a cup of vomit had pour forth in my garden seam . Pleasant , right ?
This was unlike any mushroom-shaped cloud I ’d ever seen . Did a bozo come in my yard and puke ? Was this stuff and nonsense dangerous ? Harmful to contact ? Or breathe ?

Turns out , the aptly named cad vomit fungus is reasonably coarse in gardens and despite the crude name , it ’s neither dog puking , nor a fungus .
So if it’s not vomit, or fungus… what is it?
This strange “ fungus ” is just one out of over 900 different types of sludge mold . Slime mold is the casual name given for a soil - dwelling , single - celled primitive organism that combines with other cadre to take shape a plasmodium — essentially , a blob ( kind of like an ameba ) .
The plasmodium , which motley greatly in size depending on the species , moves around in a creeping or creep personal manner as the cadre breed , consuming the bacteria in constitutional matter as it go .
Plasmodial slime molds belong in the phylum Myxomycota in the land Protista , and the most common ooze mold that appears inmulchesand on lawns is from the genus Fuligo ( which , confusingly enough , is not in reality mold even though it ’s prognosticate slime mold ) .

That unearthly , foamy , gall - comparable blob is a species called Fuligo septicai — though I have to accept that its vulgar name of “ detent vomit fungus ” or “ scrambled egg slime ” have a better ring to them , ripe ? Ha !
Slime mold get out as a guileless moving-picture show , almost like bollock white . Most mass do n’t notice it in their yard until the plasmodium changes into a spore - endure fruit body ( like to a mushroom ) called an aethalium — a thicken , cushion - like , irregularly - shaped social system that ’s whitish , tan , bright yellow , or orangish in gloss . This change usually happens in the eventide , so by the next day it seem like the “ emesis ” just magically appeared .
sludge mold is all harmless to humans , beast , and plant life . Perhaps the only ( rare ) endangerment to neighboring plant ( particularly minor seedling ) is being put out by the blob as it grows .

But slime clay sculpture is n’t after your plants , even if it ’s growing around the root of the bow — it feeds on decay organic matter , which is why it ’s often seen in mulched domain where the mulch is set about to break down .
How this mysterious slime mold suddenly appears in your yard
Dog vomitus fungus can appear anytime from late spring through fall in warmer weather condition and moist condition , whether from rainwater , humidity , or excessive lacrimation .
It thrives in suspect places , so in my cause — where a hot , dry summer prompted me to irrigate more frequently and overlay my beds with shade cloth — the mess of consistently moist straw mulch made for a double-dyed breeding ground for plasmodium to grow and spread .

Dog nauseant fungi appear on every continent ; their origins are in the trees that make up the mulch they usually raise on . They can be found in bark mulch , rotting logs , Sir Herbert Beerbohm Tree stumps , untreated lumber , and leaf litter .
Even though it sound kind of cool and sci - fi to learn that the blob can move on its own , you ’re not likely to witness actual move unless you havelotsof posture clock time to observe this .
Like true fungi , slime mildew is spread by spore through the atmosphere . After it goes through the slimy stage , it begins to crust over and turn brown . If disturb , the spores will gasp up ( like a brownish - disgraceful cloud of rubble ) and disseminate to nearby areas .
Touching , move , or spray pee on the crusted blob at this point , in its mature stage , will only increase the amount of spores that diffuse in your garden ( which is n’t of necessity a “ unfit ” affair since it ’s harmless — but it ’ll result in these unsightly organisms depict up in greater number next season ) .
How to get rid of it
The most good direction to get rid of frump vomitive fungus in your yard is to polish off it while it still looks like gunk . To keep thing as straight and clean as potential , I like to splay my script into a plastic suitcase , carefully foot up the slime ( including any mulch it ’s bond to ) , turn the bag inside out to control it , then flip it in the meth .
Using any peter to foot up the wiener puking fungus will stick the spores to your tool , meaning you ’ll have to spend fourth dimension cleaning your tool to verify it does n’t diffuse to other areas of the garden .
Do n’t strain to compost or burn the andiron puke fungus , and definitely do n’t permit it turn to the powdery microscope stage before you get rid of it . If itdoesturn to gunpowder , do n’t hose it down to wash it aside ! ( Oops , been there , done that . )
Remove the dog emetic fungus as soon as you see it , and you wo n’t have to deal with a slime mold problem later on .
But what happens if you simply rent it be ? Since frump vomit fungus is innocuous , do you really need to control it ?
No , not really . If you allow the dog vomitus fungus alone and dial back your tearing , it ’ll just harden , fade in semblance , dry up and decay , becoming less noticeable in your railway yard . Itdoesleave behind million of spores that ’ll get carry away by wind to grow again on another solar day , continuing the cycle of healthy ( and free ) decomposers in your garden .
think of that dog vomiting fungus only appear when precondition are just right for it to survive : lovesome , wet , and shady . If you use better lacrimation habits and expose your garden to more sun ( by pruning trees that may be casting shade over your plants , for example ) , you ’ll make things less desirable to slime mold .
