Disposing of spent cakes - risk to nearby trees?

Hi,
Has anyone got any advice on disposing of spent medium. I've been dumping spent cakes from various grows on my vegetable patch but I have some oyster (citrinopileatus, eryngii, djamor and sajor-caju), Armillaria mellea, Panellus stipticus, and more cakes.
Can I put them on the compost heap which is a few metres from some apple, cherry and fig trees?
What sort of distance is safe from a tree for Armillarea mellea (should I pasteurise the spent cake first)?
Are grape vines safe from any of the above?
Is it better to just put some things in the garbage?
I'd like to put the live oyster on the compost heap if it's not a risk to my trees.
The tree roots probably extend under the compost heap.
Any info about these and other species of mushroom or potential hosts would be handy.
Cheers

Nothing to worry about unless those tree's are dead, and in which case I guess you wouldn't care at that point. There is a chance that the eryngii will attack roots of tree's, it's mildly pathogenic to roots.
I'm not 100% sure but I don't think it's powerful enough to kill a tree.

Are you including the Armillaria mellea in that or just the oysters (all species of oyster safe)?
A. mellea is a rampant pathogen that has rhizomorphes that can spread a long way (wikipedia "In one example, spread by rhizomorphs from an initially infected tree killed 600 trees in a prune orchard in 6 years.")

I know nothing of Armillaria mellea, I was thinking along with gourmet oyster's. Armillaria mellea are not gourmet so I apologize, just read on Wiki.
Here you go, some data here. Destroy, burn or landfill.

Armillaria mellea is a notorious parasite, so you should desiccate these and throw them away.
You crumble an oyster block into hardwood chips, no bulk outdoor preparation. The mulch harbors a community of microorganisms that the oyster mycelium must compete with. We're not trying to cultivate anything but you may get bonus crops because oysters are aggressive.
Eventually 50% of the substrate is liberated as carbon dioxide, so ground cover will thrive and encourage more mushrooms. The composted substrate will hold water well and bioactive water will leach out of it. It's about 20% each compost and water. The rest is mushrooms, wild and gourmet, that will decompose.
You dispose of one block weekly this way. After a year the substrate will have frozen and thawed, and have secondary and tertiary decomposers. It attracts earthworms, who secrete a "worm juice" even more potent then "mycelium piss." The leaves fall and become a kind of casing layer.
Over the second and third years the border between mulch and earth will be a rich loam grown through with microbial life. A complex weave of mycelia grows downward, among which species are mycorrhizal ones. The soil is very much alive.

Update: Winter is the season to make microbial topsoil. Here's an easy recipe based on the above post.
One spent shiitake block can cover 3-4 ft2 of topsoil. Crumble the sawdust around the whole garden bed, spread a handful of gypsum, and mix in enough mulch to cover most of the spawn. Water deeply and ignore until spring.
I already had shredded leaf mulch in the bed. The goal is to attract diverse microflora that feed on the mycelium. Use a recognizable species so you don't mistake weed fungi for volunteer crops.
