| I have a noticed white fungus (see pictures) growing in various places around my yard in the mulch beds. I have not seen anything like this in the past so my guess is it came with the much (last month). Does anyone know what this is if I should be concerned about it?
It seems to grow in a matter of days and then die back over the next week or so.

| I have a few spots of the same. My understanding is that it's to be expected given the humidity & heat as of late. I have it in old as well as new mulch. I have read that increased phosphorus levels can contribute to fungal growth, but I haven't found any correlation with the fungal blooms in my mulch. (ie, I don't notice in particular after I fertilize.) Rather, I DO notice it when we have a hot, sticky night--the sort of weather you'd expect fungi to love. :-) I just ignore it and assume it's another way of breaking down organic matter. |

| That's exactly what it is.....the signs of ongoing decompostion in the mulch itself. Warm weather, moist conditions and dead organic matter (the mulch) all combine to create a haven for busy fungi :-) Totally normal and quite harmless. |

| That would be the ever popular dog vomit slime mold...not a mold and not a fungus, at all. Not classified in that kingdom, anymore. Thus JonCraig's observation that it doesn't seem to follow the same reproductive pattern as fungi. Totally weird (read:cool) stuff. There are many different kinds of slime molds that are common in our North American yards and gardens. They can even 'move' across surfaces such as concrete! These organisms come in lots of colors, too. |
