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?

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

"Cyphobasidium buelliicola Diederich & W. R. Buck,
sp. nov.
Diagnosis : Characterized by the waxy-gelatinous, orange-brown, pulvinate basidiomata, 0.2–0.45 mm diam., developing on Buellia stillingiana, the elongate ellipsoid probasidia, often with a stalk-like base, 18–32 × 5–8 μm, the cylindrical, 3-sep- tate meiosporangia, 30–40 × 4–6 μm, the cylindrical to subuliform, 1.5–2.5 μm thick and 5–7.5 μm long epibasidia, and the ellipsoid basidiospores, 5–6 × 3.5–4.5 μm."
This odd gall forming fungal pathogen was collected swelling portions of the inflorescences of Schefflera digitata.
Swollen galls were part of the developing inflorescence; inside is dense brown powdery spores.
I posted it to mycologist Eric McKenzie on 15 October 2008 for identification. I expect the specimen is now in the NZ plant pathogen collection of Landcare Research in Auckland.
This was one of the finds on our third annual Tour de Hinewai bike bicycle cycle trip.
This has voucher number JJS-061028-5 in my personal specimen database.
On Rosa virginiana; or could be Rosa carolina; either way, an indigenous Rosa species.

Thecotheus pelletieri. ascoma are at center of photo. It is the only one in its group with 32 spores. The others have 8 spores. On horse dung. The perithecia is white and gelatinous and less than 1 mm wide. Asci: 44-6.4 x 324-376 um. Spores: 12.3-19.7 x 24-45.6 um. Paraphyses are 7.4 um wide and enlarged at tip. On horse dung. M4202
Thousands of tiny dark oblong dots, mostly connected to blobs of fungus on a rose leaf. The entire dark colonies of about 100 dark dots are each about 0.4mm across. The individuals not in colonies weren't visible to my naked eye. So these dots are small, maybe 1/20th of a mm (50µm).
On a dead branch of hardwood. This is some kind of hyphomycete (is it synnematous or pycnidial?). The fourth photo shows a section through one of the fruiting bodies showing conidiospores developing in a chamber embedded in the wood which travel up the neck through a rather broad channel to the apex of the neck which protrudes from the bark.
Conidiospores:
Hyaline with oil droplets, ellipsoid, smooth, aseptate

N=33
Me=10.3 x 4.2µm

I could not access the type descriptions to see if this matched the species, but found this int he 2018 paper by Viacheslav
"A preliminary overview of the corticioid Atractiellomycetes"
"Helicogloea eburnea is closely related to another asexual
species of the genus, H. compressa (see above). Morphologically,
they are evidently indistinguishable but differ in their DNA
sequences and geographic distribution."
The description of the apparently indistinguishable H. eburnea is here.
Sporodochia pustulate, gelatinous and soft, white
semitranslucent; separate pustules up to 1 mm diam and 400
µm thick, partly coalescing, in herbarium shrinking to a thin,
waxy, yellowish film. Internal hyphae with thickened (up to
0.3–0.5 µm) walls, 1.5–2.5(–3) µm diam. Surface hyphae thin to slightly thick-walled (wall 0.1–0.3 µm thick), 1.5–2 µm diam.
Conidiophores irregularly branched, branches generally parallel
to the main axis. Conidiogenous cells cylindrical to slightly
obclavate, straight or curved, tapering to the apex, with multiple indistinct annellation scars at the top, 12–34 × 1.5–2.6 µm.
Conidia subglobose to ellipsoid, smooth, hyaline, slightly thickwalled, (2.8–)2.9–3.7(–4) × (2–)2–2.6(–2.7) µm (n = 30/1).
Measurements of this obs. on all accounts are at the top range or larger than what is reported here.
