I am sure of the correct species here but this one and a number of other fruiting body’s were yellow. I suspect there is something growing on them, any one have a suggestion as to what this could be?

if it’s a red capped form transplanted from the Western US, this one is flavivolvata. I was horrified to read that muscaria var. muscaria also can show yellow warts in youth; so much for quick and dirty macro IDs!
I wish to thank every one who has responded to my posting as I understand it Amanita muscaria is an introduced species to New Zealand. The habitat from which I found this fungus is a give away as to species (from under pines) there were others more mature with there bright red caps and white warts. None of our native species found in this region could be mistaken for Amanita muscaria.
What cough my eye was the yellow warts but if you look close you will see that the tips of some are still white. I suspected that some sort of hypomyces might have gotten to it.
yellow universal veils can be found in a number of muscaria varieties (formosa, regalis, etc.), but only flavivolvata has the yellow veil on a red form.
regardless, the yellow is veil material and not, say, a hypomyces.
and yes, i do believe that your muscaria is all introduced.
This is prob. what you have here.
“Because yellow warts are not uncommon in the type variety, microscopic characters must be used to distinguish it from the North & Central American native, Amanita muscaria subsp. flavivolvata Singer. Distinguishing microscopic characters include difference in the thickness of the subhymenium and differences in size and shape of their spores.”
As far as i can tell, all Southern hemisphere muscaria species are transplants.
