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
8.6-12.5 x 3.8-4.9µm
Q=2.0-3.0
N=33
Me=10.3 x 4.2µm
On salt grass
Salix. Aecia developing in clusters, only on abaxial side. Chlorosis on adaxial.
Microscopy done- will update with that.
Goopy, but with some form, semicircular, up to 6mm across.
Microscopy in H20
Conidia: Subglobose to elliptic.
(3.4) 3.6 - 4 (4.5) × (2.5) 2.7 - 3 (3.4) µm
Q = (1.2) 1.3 - 1.4 (1.5) ; N = 15
Me = 3.9 × 2.9 µm ; Qe = 1.3
Conidial Hyphae: 1.91-2.9um wide.
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.

An appearance like galls on this Common Lambsquarters, Cheopodium album.
On leaves of Erythronium americanum, with Vankya heufleri (https://www.inaturalist.org/observations/208696306). The coloration is strange and I have no idea what it is. The spheres, viewed under 800x, could burst open and release its content.
Spores: 8.7-9.7µm
Sporotheca: Dark, with gold operculate lid
Sporocarp: 0.65 mm
Substrate: Picea (spruces)

some weird rust thing on Ribes sp. the Ribes kinda reminded me of Ribes rubrum, but not sure.
doesn't really resemble Cronartium ribicola. is it even a rust ?? who knows

leaf spots on Taraxacum sp.
possibly Ramularia taraxaci?
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.

Datos de Yopal: registrado en Bosque Seco Tropical (temporada de lluvia). Precipitación mínima de 15 – 25 mm en los meses de enero y diciembre, precipitación máxima 350 mm y 300 mm en los meses de mayo, junio y julio; con menos de 60 mm de lluvia en el mes más seco y precipitación anual superior a 1270 mm. Cuenta con valores mínimos de humedad relativa a inicio del año (65%), y valores más altos en junio, julio, agosto y septiembre (90-85%). Cuenta con una altura sobre el nivel del mar entre 0 y 1000 m, una pluviosidad entre 2000 y 4000 mm y temperatura promedio mayor de 24 °C, con amplitud de temperatura máxima de 8 °C, como se referencia en DANE. Los máximos valores de temperatura no sobrepasan los 36 °C y los mínimos valores no logran bajar los 19 °C que se presentan en febrero y en julio, respectivamente. Temperatura media anual mayor de 20 °C, con una estación seca y una lluviosa bien definidas (Bustamante et al., 2017; DANE, 1999; Castro y Sosa, 2017).

Te dejo algunas recomendaciones para tus registros. Las fotografías y descripciones que hagas, te van a permitir identificar el ejemplar: más detalles ver: https://colombia.inaturalist.org/journal/teodoro_chivatabedoya/54937-registro-de-hongos-macromicetos
-Tomar fotografías de las diferentes estructuras del basidioma/ascoma/cuerpo fructifero/carpoforo/seta (por encima, por debajo y de perfil), su estipe (píe), píleo (sombrero) y base. En el caso de retirar el ejemplar sin conocerlo, debes comprometerte a realizar una descripción detallada para aportar a su conocimiento y que no quede en una muestra arrancada, fotografiada y desechada. Para trabajos de identificación, es necesario que retires el ejemplar completo, sin cortar o maltratar la base del estípite, de igual forma, tomar nota del tipo de sustrato (material donde crece y desarrolla).
-Es importante que describas las dimensiones (altura y diámetro), forma, consistencia, textura, color y olor. Recuerda que los ejemplares cambian bastante según su estado de desarrollo, así que es ideal familiarizarse con la zona y temporada en la que crecen, para hacer un seguimiento y logres observar la variabilidad fenotípica del basidioma o ascoma (cuerpo fructífero).
-Toma fotos del entorno y agrega datos del ecosistema (humedad, temperatura, altura, tipo de bosque, insectos asociados, etc).
-No olvides que la determinación de macromicetos es compleja y no se realiza únicamente con fotografías, esta tarea (a nivel de género y especie; en la mayoría) implica actividades de descripción morfológica externa e interna, esporada, reacciones químicas, microscopia e incluso herramientas moleculares (ADN/PCR).
