What's growing in my graveyard???

I went to watering my outdoor spent blocks and noticed a big weird yellow pom pom growing on one block, like lion's mane just before it starts growing branchlets... but I watered it and it melted and changed color to orange I don't know if this block was of laetiporus sulph. maybe you know what is it? sorry for the blurry pic I haven't got the camera when I saw it.

 

Got any pics of the bottom or side? Could it be a giant L. Sulp. blob? That would be cool!

 

looks like Calvatia rubroflava.

 

Tasty!

 

Sorry I haven't more pics, tomorrow I'll shot some. I don't think it's L. sulph. or even Calvatia rubroflava because melted when I watered it, it's really weird the yellow turned orange.

 

something like this?

 

Could be it if can grow on a pasteurized and spent block

 

"When you cut into a fresh puffball you expect to find a white, marshmallow-like interior. You also expect the mushroom to turn some shade of tan or brown as it ages. Calvatia rubroflava does not fit this pattern. When injured, the flesh will rapidly turn a bright yellow; it is the only puffball to exhibit this characteristic. The white fruiting body will gradually acquire an orange brown color as it ages. As the exterior decomposes to release spores it becomes a very sticky orange mass which stains anything it touches."

"Ecology: Saprobic; frequently reported from forests, gardens, lawns, and in nutrient-poor habitats."

Definitely not Calvatia rubroflava, added some pics of how's it looking today... I broke it in half, the outside is reddish, under it is black and the layer in contact to the substrate is yellow.

 

That looks like slime mold "fruit" but it is huge!

 

Ironically I just found this slime mold fruiting in a tub of wood mulch. It is more yellow than the pic shows and is about the size of an egg only flatter. Look familiar Toni?

 

that is Fuligo septica.

 

It's similar but not that one... it was more ball shaped but it should be something like.

 

Fuligo septica

 

More unknown mushrooms for me are popping there:

 

As long as there are mushrooms, you know you're doing something right

Pluteus sp. a deer mushroom or maybe
Volvopluteus, the base of the stem looks funky, maybe it's a deformed sack of some sort
