Observation 32385: Stilbella Lindau

When: 2010-01-20

Collection location: Joaquin Miller Park, Oakland, California, USA [Click for map]

Who: Erin Page Blanchard (CureCat)

No specimen available

This was a weird one… It may have been a parasite on something; maybe the (crust?) fungus in the last photo. Both fungi were growing on a downed Pinus log, though the spiky white one that this observation is for seemed to be attached to some unidentifiable mush that was on the side of the log, next to the brown, wrinkled fungus that Noah thinks might be Serpula lacrymans.

The white thing seemed to be growing on this Serpula lacrymans.

soft? tough? easily destroyed? that should give you a hint to its identity…
aren’t all slime molds super-fragile?

The micrographs are very low magnification- 10×. The structures are…. Well see all of the spiky, white projections? It is those things magnified. I think I must have looked at the brown (gleba?) interior, and I think I recall it being uninformative, but I’ll see if I can find this thing again. I saw it in a bag around here somewhere.

Could you label the microscopy?

What is the magnification and what are the names of the structures you are showing us?

the second to last image looks like if it is a mxyo Reticularia lycoperdon, which i have seen on conifer (though not slime mold preferred habitat) But in my experience, i have not seen P tomentosus this clustered on anything before, and i agree that at least for the shape, if it were, it would be a different Polycephalomyces.
I have seen B. maxima crust over like this but not on pine. The scope images dont look like myxo spores. Do you have one of that fungus?

I don’t know about P. tomentosus based on the photos I have seen… In the other photos, the structures are much more widely spaced and consistently ball-on-a-stick shaped, and here they are dense and irregular.
