Gall, possibly Melanopsichium pennsylvanicum, or some sort of mite, midge, or other life form.
Helicodendron conglomeratum
( distal end of the coil is going clockwise, shown on the last photo)
On submerge wood in a stream
On Erigeron. Chasmothecia seemed to be only on the bottom of the leaves, but conidiophores were on both sides. No appendages whatsoever. One ascus per chasmothecium, eight spores per ascus.
Rust fungi on Salix atrocinerea leaves.
Spores round, with prominent cell walls
Smut fungus seen on Carex fruit
On Juncus tenuis stems. This is in my yard, so can easily revisit and collect if needed.
Common all over Berkeley Campus under limbs of living Quercus agrifolia. Third photo shows scale insects that were covered by mycelium. Forth image is a basidiospore, and the last two show germinating probasidia, and septate metabasidia.

Some sort of fungus underneath the hemlock needles (not HWA - I see the aestivating adelgid but thats not what I'd like to ID)

some kinda rust on a grass (rush?)
on Pteridium aquilinum, prev obs.
Abundant large telia, hypophyllous (maybe amphigenous) on Solidago. Puccinia stipae stand out as a possibility among the Puccinia spp. that grow on Solidago, since the teliospores are relatively wide.
Measurements
Teliospores
40–52×24–26 μm
Urediniospores
23–26×20–22 μm

Not sure about this ID
On Morella sp., prev obs
Whoa! the USDA Fungal databases only list ONE species of fungus affecting Morella sp, and it's not a rust. I can't find any info about rusts on Morella at all :-O*
*granted, I looked for only like 3 minutes... but that's usually enough to give me SOMETHING.
Orange coating on ellipsoid/spheroid growths on Clematis stems, possibly Clematis virginiana.
Micro is at 400x. One photo shows powder (presumably spores) dropped only a slide; other photo is a smash-mounted sliver of the ellipsoid/spheroid growth.

closest reasonable guess I can come up with, on Myriopteris parryi
On Gymnocarpium dryopteris
I found this on Clematis virginiana. What I read about this rust suggests that is not typical.
On Puccinia modiolae. Was thinking it may be Cladosporium uredinicola, but now I'm leaning towards Sphaerellopsis filum.
On Erythronium oregonum. Possibly Ustilago heufleri ?

tentative ID. should be this or Puccinia smilacis. rust on Apocynum cf. cannabinum.
Maybe? On eastern hemlock
Dark stuff growing in a pattern on Eriogonum nudum indictum stem. Fairly common on this species here.

Anyone know what the powdery yellow is? Some kinda mold or fungus?

On hardwood. Brown and shriveled in the field, but rehydrated when left in a moist chamber for a day. Hymenium yellow, becoming orange brown. The receptacle is scurfy brown. Clustered and erumpent through the bark. The largest slightly larger than 2mm in diameter. Some with short pseudo stipe.
Asci:
IKI-, croziers+, clavate, 35-54 x 4-7µm
Spores:
biseriate in the asci, hyaline, fusiform, sometimes slightly curved, usually with two oil drops,
5.0-7.6 (8.5) x 1.7-2.0 (2.3)µm
Me 6 x 1.9µm
N=48
Q 2.5-4.3 MeQ=3.1
Paraphyses:
septate, slightly tapering, about 2µm wide
Ectal excipulum brown, textura angularis.

Collected on the Ohio Mushroom Society’s 2019 summer foray. Growing abundantly on Onoclea sensibilis leaves in a swampy area. Apparently causing discoloration on the upper leaf surfaces and white, fluffy growths on the undersides. Uredinospores beaked and roughened. Uredinospore measurements: (32.7) 37.4 – 52 (59.5) × (9) 10.8 – 13.7 (14.6) µm, Q = (2.4) 2.9 – 4.6 (6.6); N = 30, Me = 43.8 × 12.3 µm; Qe = 3.6
