Long Island City, Queens. Cobblestone Courtyard. Neglected flower bed & fissures between cement squares. Going with iN’s identification but not sure if correct.
Marine Park,Brooklyn. Grassy areas near Nature Center, especially under trees.
Wider overlapping lobes. Row of differentiated ocelli, “bucket” shaped lower leaves evident under scope. Growing on outcrop of Shawangunk conglomerate.
Green shade form on Quercus rubra with >250 annual rings.
We thought this huge polytrichum with 12mm long leaves and 10cm long stems might be P. commune but a cross section revealed no "C" shaped cells. Further investigation has pointed towards P. formosum. The lamellae are in about 30 rows and are 4-5 cells high. The cells of the margin (the teeth) extend 3 rows out from the lammelae. The cells in the teeth are about 8um wide.
This was growing in a very moist shady area. There were sporophytes present and I really wish I had collected one to see if it was sulcate.. but there were so few sporophytes that it did not feel right to collect them.
With an interesting fungus on the leaves

Leafcutter bee (Megachile) track on Oenothera speciosa leaf in my front yard, July 2023
I have been hoping to see this for a while, but am still not sure if it actually is Isoetes. There are about ten.

Small specimen of a little known brachiopod found mainly in S. CA but also described as far north as Tomales Bay. It has turned up in a few recent surveys in Elkhorn Slough. ID and info from John Pearse and Mark Silberstein.

Rufous-backed cellophane bees (Colletes thoracicus) nesting aggregation, along my driveway, May 2023.

I've observed this population in my garden for 16 years, since 2008. This is just one small section of the area in which they nest along my driveway.
Larva 4mm long. 1st two images are 20 x; 3rd image is 10x.
Leaf-folding larvae on Quaking Aspen/Populus tremuloides leaves. In most but not all cases, the fold is next to a roughly circular eaten area. In most, but not all, cases, a single leaf will have folds on two sides of the leaf.
Too small to roll over to count prolegs, though it looks like six in first image, hence sawfly larvae and not caterpillar. I'll check back to see how they grow...
Note: leaf and larva specimen collected with permission.

In bog in Staten Island; bracts with 4 lobes or more; clusters of gemmae at branch tips.
At a wet pond edge. Not sure, it doesn't look too similar to the online pictures of Bryoandersonia. But I don't know other options. What looked like terminal spines are present on the costae; axillary hairs present; margins sometimes revolute; leaves strongly concave; mid-leaf cells not very long.
thallus K+ y to r. spores not examined.
18 × 16 mm thallus with apothecia ≤0.5 mm on brownstone, K+ purple
