Sporophores stalked and subglobose with a deep umbilicus and limeless opaque stalk
Sporocyct 437µm (0.4mm)
stellate CaCO₃ on the peridium
Capillitium is without spirals colorless with dark swellings and branched.
Spores warted 7.6 - 9.3µm
One of two on the trunk of a White Oak/Q. alba sapling sourced in a nursery in Millstone, NJ. Tree was planted here in the Green-Wood arboretum on November 13th or 14th, 2023.
I feel pretty confident that the snails came in with the tree.
Both snails seen in final image. These are presumably the same species; but I've made separate observations for each individual if they're not. The other: https://www.inaturalist.org/observations/191471604
Maldanid worm sampled with an IKU grab on a DFO Quebec Region biodiversity survey.
Looks like a bunch of eggs growing on the old fish hook…
Added images from another camera for more details
Thinking maybe snail eggs...
@ipat @clauden @susanhewitt would love to have thoughts on this oddball.
from shell hash.
The outer shell layer is mostly eroded, just a couple shells have some spiral ribbing left. (maybe the brown colour is just staining, but I found nothing similar that was not brown).
The upper left are all Hydrobiidae (Hydrobia/Ecrobia) and I think the rest are the same, just worn & no longer translucent, but I am not sure.
An unusually "tall" one.
100x from bronx river.
Shell has nodular projections in regular intervals on the surface
Found in area with a lot of Brown-lipped Snails, but this is flatter, more translucent, lacks flared lip, and has a small open umbilicus.
Image 4: Brown-lipped on left for height/elevation comparison.
Got to Crandon faster than expected before meeting Ahn Feldman, @mecopteron_bouillon so did a little poking around on some rocks near the southeastern end of Bear Cut Bridge.

I found this on a muddy intertidal zone, in the middle of a long estuary. A few marinas were nearby, so the bivalve may have been a species found in deep water, brought up by fishermen. Another possibility is that it was a freshwater species in the river. I believe it was a mussel, though it may have been a clam.
Shell length approx. 1-2 mm.
Upper intertidal, under a moist smooth boulder of sandy mudstone.
Button blanks from wild mussels discarded into or along the river.
Date is a wild guess, though it hardly matters. These poor organisms may have died nearly 100 years ago. Found in the mid- 80's on the river at Meyer, IL.
This observation is for the small holes on this northern quahog. Not sure if the various shapes and sizes were all made by the same organism or by several.
Shell collected by my kids sometime in the past few years in Shirley Chisholm State Park off Jamaica Bay.
Detached from Plumed Worm casing seen in 4th image. Centimeter scale.
This was a fun puzzle we found in the woods at Glenmeal SF. It’s a Fomes fomentarius conk with a bunch of markings, eventually I figured out those are left by the radula of a snail / slug. Apparently you can identify some taxa (families? Genus?) by the pattern— anyone have an educated guess?
Found on beach
Observé lors d'un relevé de pétoncle par MPO-Québec / Observed during a scallop survey by DFO-Quebec.
Still alive? I threw it back into the water.
Placopecten magellanicus (Gmelin, 1791)
Mid intertidal zone, Raritan Bay, Port Monmouth, Monmouth County, NJ
found numerous, though hard to get ones without small hermit crabs in them.
Bore holes in peat. I didn't dig into it, not wanting to kill any of the Barnea.
Recent (2019) SARA report says B. truncata only bore in red-mudstone in NS, but that is incorrect. This site has them living in their more typical habitat: peat/mud
Three views of the same individual.
6mm long
Collected from shell hash
small individual Not worn at all, showing scales/spines.
