are going to take note of, be interested in, and offer up comments or suggestions on your or anyone’s observations depends entirely upon the comprehensiveness and attractiveness of the observation in question, along with the dumb luck of who is around to see it in the activity log. Unfortunately, your photos are either blurry, from too far away or of low resolution, which hinders any attempts at making an identification. this is probably a slime mold, and probably at its plasmodial stage, which also limits the amount of IDing that can be done, as the sporangial stage is often much more diagnostic.

your “unknown wood bit” looks much too gelatinous/fleshy to be wood. it appears fungal, which would make this slime mold fungicolous (growing on fungi). perhaps return to this specimen in a few days and see how it’s developed. if you have a dedicated camera (as opposed to a phone), that may capture some clearer photos of the fine details.

You do not need to concern yourself with the taxonomic hierarchy. that is outside the scope of this observation.

Ok. I do understand what you are saying…

… and I will comply.

However, I don’t understand why this site (or you) isn’t (aren’t) interested in trying to drill deeper than order in the taxonomy? Are we not interested in class and not only order?

I’m sorry if I’ve bollocked the formatting, however:

Does this observation not conform to the description of “Eukaryota —> Amoebozoa —> Mycetozoa —�> Myxogastria —> Myxogastromycetidae —> Physariida” ?

Or should it be: “Eukaryota —> Amoebozoa —> Mycetozoa —> Myxogastria —> —> Physarales” ?


The description of the type of sporangia conforms with the observation, no?

perhaps you don’t understand. This observation is fine. It doesn’t need to be changed.

the name you proposed, however:

Myxogastria Myxogastromycetida Physariida

was new to the site. it is three names in one, which is erroneous.

as a new user to Mushroom Observer, I am asking that you refrain from the creation of new names. you will know that you are creating a new name when the site tells you that a name is not recognized and asks if you’re sure you want to create it. it looks like this:

…. it looks like its body conforms to that diagram from wiki

Changed proposed name spelling again, seems to be different spellings…

Is there no interest in drilling deeper into taxonomy?

Sorry, I looked it up on wiki and and it looks like the fruiting body is of listed type

See reference link….and I said could be… I fixed spelling

please be wary of creating new names. Myxogastria clearly already exists on the site, as evidenced by the proposal directly above yours. look for the warning text when you are about to create an unrecognized name and then check your spelling.

Allesklar, looks like it might be….

…Myxogastria Myxogastromycetidae Physarida from the wiki reference diagram of fruiting bodies… very interesting. Thanks

do not have Mycelium, they are one celled organisms. They are plasmodial or slime. Easy to hide on a jelly fungi. The white structures are actually just the fruit of the Myxogastria.

Can jelly fungus have fruiting bodies like those?
By: TNred

Definitely seems like the fruiting bodies are emanating directly from the black mass, without any other mycelial strands or anything resembling mycelia attached to bodies…

Looks to me like a jelly fungus or maybe even a lichen.

Slime mold?

It appeared to be a slime type mold w fruiting bodies coming out of it…

This is odd

Is the black substance wood or another fungus?
