Thank you!

oblonga:
🗣️: /əbˈlɒŋɡə/ — uh-BLONG-uh
From Latin oblongus, meaning “longish” or “elongated.", the species epithet lends itself to this oblong shaped fruiting body.

Let me know if you have a favorite photo out of the 3!

Physarella:
🗣️: /ˌfɪzəˈrɛlə/ — FIZ-uh-REL-uh
From Greek physa (“bladder” or “bubble”) + Latin diminutive suffix -ella (“small”). This Genus is characterized by small globose/oblong sporangia often with lime-containing capillitium.

The species epithet ferruginosa also has Latin origins:
"ferrugo" = rust
"osa" = full of

So ferruginosa means “full of rust”, describing the reddish-brown color these fruiting bodies take on when fully mature.

But its scientific name tells a different story. The genus Tubifera comes from Latin roots:
"tubus" = tube
"fera" = bearing

Together, this means “tube-bearing”, referring to the clustered tubular sporangia that define the genus.

Spotted on a leaf in Forest Park, but who knows where else it’s hiding in NYC. Keep your eyes peeled for twinkles in the leaf litter. ✨🦠

At 1000x magnification, the spores show evenly spaced warts, no grouping. Another clue for ID!
Nature’s sparkle — inside and out. #microscopy #plasmodialslime

There’s a “collar” at the top of the stalk — something also seen in Collaria arcyrionema, a close cousin that used to be grouped with Lamproderma.

Its internal structure is just as striking:
Capillitium branches directly from a short columella, forming a scaffold that persists after the outer wall dissolves. Very architectural!

The species epithet scintillans is Latin for sparkling, glittering, twinkling — perfect for this shimmer-covered beauty that catches the light like foil.

The genus name Lamproderma comes from Greek:
lampros = bright, splendid
derma = skin
✨ A reference to the shiny, metallic peridium these slime molds are known for. #myxomycetes

Awesome!

O. Favoginea would be my bet. Microscopy would confirm.

No. Complex Lycogala epidendrum is non-toxic. No known Myxomycetes are.
