Along edge of MDNR snowmobile / ATV trail at bridge crossing of Laughing Whitefish River
Swimming in a freshwater pond
Buds finally starting to show.
Mystery tree.
Maybe Japanese tree lilac ?
A small snail with a flattened / planispiral, iridescent shell, found in a vernal pool
In a vernal pool. This particular individual had a beautiful marbled blue coloration on the upper half of the body and two orange down the lower half of the body. A cool little crustacean !
A larva can be seen in a gelatinous mass attached to a hickory (Carya sp) petiole
A tiny sapling that seems afflicted with some rust fungus. The young stem is pubescent. I scratched the twigs and they didn’t yet have the sweet wintergreen smell, so perhaps that’s not always detectable in saplings?
About 3.5 mm in diameter. On an Eastern cottonwood flower. A slug made a cameo in the last photo.
The owl was calling for a while and then went inside the cavity in a large Chestnut oak
Red leaves. Maybe Water purslane (Ludwigia palustris)?
On Salix nigra. https://www.gallformers.com/gall/3678 reports the host as Populus deltoides only, however, Salix nigra, which is also in Salicaceae doesn't seem too far fetched.
Twigs yellow. Buds tiny. Twigs snap off very easily.
lack pigmented granules between perithecia; no KOH-extractible pigments
Silvery gray lesions on Erythronium americanum. Spherical double walled black spores.
Male tree on the left (red flowers). Female tree on the right (greenish yellow flowers).
Naturalized near a highway
Growing amidst Multiflora rose, near a highway.
Globular clusters of rusty brown perithecia on an old Celastrus orbiculatus vine. On a bridge over a highway. The clusters were about 3nm in diameter. I'll attempt to do some microscopy and will check for KOH extractable pigments later.

Light gray/tan bark, somewhat warty due to the numerous lenticels. Opposite branching. Growing near a vernal pool. I am eager to see the leaves on this small tree. The only thing that comes to mind is Fraxinus ornus?? I believe F. ornus has angular twigs as seen here, but I'm not sure.
This fungus infects Box elder (Acer negundo) and turns the twigs white, killing them. Sometimes the fungus looks like broken up black circles (see photo 1), a bit like cheetah spots, and sometimes it looks like complete circles. I have seen similar Box elder twigs with this fungus, where part of the pale twig was an orangish pink hue.
After letting the twig sit in a moisture chamber, pinkish goo started to ooze out of the black circles. I believe this is an anamorph of some Ascomycete. A photo of the conidia at 1000x is shown. The spores are elliptical / pill shaped and have numerous round guttules in them.

The scrapings are probably created by a snail scraping its radula. Interesting texture on this black pyrenomycete. The close-ups are from a dead Sycamore maple. One of the larger Sycamore maples, shown in the last photo, appeared to be covered with sooty mold, so perhaps it's also infected by the fungus.
White hairs on lower leaf surface. Growing in an area where Allium tricoccum grows, as well. This could be A. tricoccum, since it also has that kind of a pink sheath at the base of the stem, but I've never seen hairs on their leaves - perhaps they only appear on very young plants ?
With unknown cankers, possibly caused by a fungus.
For the possible cause of the cankers, see:
https://www.inaturalist.org/observations/204950069
Pits in Lindera benzoin trunk. This is a very common condition in New York City. Concentric scarring is visible within the pits. Perhaps these are caused by Neonectria ditissima, which is known to cause "target cankers" (Apple canker) on a large number of hosts. In Alley Pond Park, I see large cankers caused by N. ditissima on Betula lenta.
For the plant, see:

Near a saltwater creek, in sand. Lots of grasses, mugwort, wild bergamot around, evening primrose and young black locusts.
Globose spores that appear warted / ornamented
Marine Park, Brooklyn 3/30/2024
Twigs very "fragilis" - break off almost at the slightest touch.
Submerged under water, on an oak leaf, in a fresh water kettle pond. Much of this pond dries out in the summer, but it's not completely ephemeral. The spiral winds clockwise if you look at the apex of the snail. The opening / aperture is on the right when looking at it, while the snail is held vertically. I think that rules out Physella acuta, which has the aperture on the left.
A very unusual puffball-like mushroom, except unlike puffballs, this mushroom had a stalk. Growing in dry sand, by the shore of a salt water creek. The last two photos show the habitat.
Near a saltwater creek. In dry sand, with lots of grasses, mugwort around.

on a hardwood log at the edge of a vernal pool. distant lanceolate leaves with fine tips
Leaf cells elongate; on shrub bases in swamp.
Found under a log. I believe this was a mother guarding her eggs.
This moss was covering a branch that was submerged under water in a vernal pool. Strands of tiny orange eggs were attached to the moss.

Some sort of orange eggs in elongated clusters, attached to moss (Leptodictyum riparium) on a branch that was completely submerged under water, in a vernal pool. There was a sizable slimy mass containing eggs (photos 1-3), but many of the egg strands were attached to moss leaves without too much of the slime.
I found similar eggs on Carex leaves:

Male. Long antennal appendages that curve inwards and curled up proboscis can be seen in photos 4-6. Deciduous woods, in a vernal pool.
This tiny spider was about 2.5-3 mm in length. He/she was hiding under an American hazelnut leaf, alongside a Hibana species spider.
Male catkins
Tawny tufts of hair above leaf scars

The cause of these yellow bands. On a Pinus sp.twig found on the ground.
This spider was under water in a vernal pool in deciduous woods. I assume he was hunting ?
Teliospores on the leaves of naturalized bamboo in a wild forest. Found by @sus_scrofa
rust fungus on many of the leaves, across multiple stems, of a stand of arrow bamboo (Pseudosasa japonica), growing naturalized in the park.
microscopy performed by Zihao Wang, in his observation of the same specimen here: https://www.inaturalist.org/observations/203798780
A brown and white striped larva. Found under a log submerged under water in a vernal pool, in deciduous woods.
Stamens merged into a cup, unlik Mishchenko Squill that has separate stamens.
Growing along a limb crotch scar of a fallen American beech. The spore bearing capsules are like tiny little gold acorns that glisten in the sun.
I first found this plant a couple of years back. I came out today hoping that it would be flowering, and sure enough, it was!
Three leaves at base of plant. Blue anthers.
