This has quite a few names but Pustula tragopogonis seems to be the latest one. I know it as Albugo tragopogonis but had just begin to call it Pustula obtusata. Never mind, Taxonomists know best. I do not like the common name here as this is really not on sunflower but Common Groundsel (Senecio vulgaris)
The first picture shows it sharing with Puccinia lagenophorae on the same leaf, with Pustula underneath, the other on top.
It is so like Albugo lepigoni - https://www.inaturalist.org/observations/57742403
On Hawthorn, Crataegus monogyna. Shrub stunted, with thick woody swellings from which many "short shoots" arise in all directions. I've put it a Bacteria, but really don't know.
Found about 1 metre from similar infection in Ash, Fraxinus excelsior

Growing on Claytonia caroliniana. Vouchered. JET230424_01
!!!
underneath a log in forest - thought they were an oribatid beetle mite at first. Lost them after trying to stop lens down for a bit more depth of field :/
On Castilleja
A few plants unearthed on side of road from road grading. Put back and tried to bury. Notable root tuber.
Presumably a parasitic plant since no leaves were observed and no plants nearby.
High Elevation
Low Humidity
Cool Temperature

Río de Suchitlán Colima
I've never seen one of these before, but I rarely wade in waterholes so it's not surprising.
Raríssima e pouco conhecida, essa planta parasita fungos micorrízicos. São conhecidos apenas dois indivíduos que estão depositados em uma coleção cientifica do Rio. Essa é a primeira foto na natureza dessa espécie.
One single plant, growing somewhat close to a trail and six feet from its host plant. New location for this plant as far as I can tell. Never been recorded here before, even in the herbarium records.
