is still a possibility, Atlides. I didn’t mean to suggest this wasn’t possible at all, as it is. There are a couple of areas within the gleba where white or whitish-areas have thickened here, but not to the extent as other obs.

And since I haven’t collected in Columbia, I could be full a a certaim common mushroom substrate…

Ultimately the only thing we at MO have to base our opinions and suggetions on is what you provide. Plus what we can see (or sort of see).

162552 is out. But what do think of 163904? To me they look pretty much alike.

Cannot say for certain,

as # 162552 was not sliced. But that species appears to be more lumpy with chambers between the latices. This does not have the same peridium as 162552.

The greater amount of gelatinous matrix, the lack of thickening in the peridium indicating a subdural laticework, and the softness point towards something in Hymenogastrales. Our species in NA have harder, tougher textures than yours. BTW, they are known to fruit year-round. So you may be able to access more collections as you like – provided they are the same genus.

I hope you can see the thickened bumps in 162552, Atlides. I can. But proving that requires the specimen to be sectioned, and I think it may be too late for 162552.

An interesting feature of NA Hymenogasters is that as they mature, the also develop more aroma. Mature H. separabile, H. crassirhachis, H. crassum have an over-ripe olive aroma, and become much more soft that the superball consistency they have while young.

it is terrestial

no odor perceived (and not tested for). Interior more like gelatinous/soft.
I’m not up to trees; all I can say is that they are all deciduous.
By the way, the # 162552 was terrestial, too.

Sorry, Atlides. Need additional clarification.

How would you describe the gleba (the complete interior within the outer peridium)? Was there an odor? Where was this found? Was it terrestrial (on soil) or wood inhabiting? If on soil, what were the near-by trees? (By nearby, what trees species were within 150 feet of where this was found.)

Texture, overall?

Was this gelatinous/solid/rubbery, or more like gelatinous/soft, Atlides?

I don’t believe this is the same as your earlier observations.

Has centralized rooting structure, as well as a developing columella within the gelatinous matrix. The columella is tree-like, and developes from the root-structure and slightly thickened basal plate. The upper peridium is not of various thickness, thinnest at the top.
