The truth.

There are many different Myxogastria with yellow plasmodium and of the 132+ species of Physarum, of which less than half of the plasmodial colors are known, there are 29 known to be yellow.
Many Myxogastria are opportunist and eat whatever is consumable and available around them. They are not host specific. To make an identification from plasmodium alone without fruiting material to examine is truly an assumption anyway.

Since the host is an oyster mushroom, I stand by this ID

How about this Danny and Patrick…

First, again someone voted against mxyogastria, which is untrue

Secondly, this plasmodium could be many slime molds. Fruiting bodies for Physarum poly are rarely photographed or seen. But there are tons of yellow plasmodium labeled as such. For purposes of going back or relabeling as Danny often does, we label this either mxyo or plasmodium.

Your input?

“Myxomycete collectors also tend to gravitate to habitats that will yield developing or mature fruiting bodies especially on ground sites such as decaying logs and leaf litter after rainy periods. Myxomycete species
assemblages are frequently associated with habitats characterized by specific terminology, for example, … fungicolous myxomycetes like Physarum polycephalum have plasmodia that feed on the oyster mushroom, Pleurotus
ostreatus; …”

are Lycoperdon pyriforme. No idea on the slime, check back after it matures.
