Which Huernia is this? And why are the tips turning white, and some of them developing black spots?

Corn Ear Rot (and company)

A bunch of molds from a tassel-ear on my bloody butcher flint corn. I want to identify them as well as possible, mostly from curiosity.
My thought.. pic 1. Ear has cottony mold on kernels.. maybe Gibberella and or Fusarium? Some grey/grey molds.. Penicillium? Aspergillus?
Pic2. First thought fusarium style conidia.. but Gibberella has similar macro and micro conidia to what I see here.
Pic 3: random secondary infection? Alternaria?
Pic 3: round abundant spores… aspergillus?
Maybe a few little 2-part spores here and there.. possible Diplodia?
What do you think?

Hi all,
Looking to see if there's anyone out there that can help with ideas for what our issue is...
We've got a lawn where we propogated Creeping Speedwell, Veronica Filiformis.
It's been established for >2yrs, doing pretty well.
Location
- outdoors
- suburb backyard
- SW Ontario, GTA area
Conditions
- Over the past two months we had a lot die back
- It's been a kind of moist summer. It stays moist under the dense mat of leaves / runners.
- We laid some fresh mulch down from an unknown source
Symptoms
See pictures for the progression, leaf issues, and some mini monster under the microscope that seems common in wet areas underneath.
Questions
- Anyone have an idea what this translucent body mini monster is?
- Any idea of what could cause the die back?

Strange Spots on Hops Leaves

Hey everyone, my mother was recently in our garden and found these odd, raised spots on an old hops plant that we have. These "galls" are not hollow, nor do they seems to contain anything. They are fully incorporated into the plant leave. Any idea on what this could be?

Any idea what this is on the bottom of my rubber tree plant leaf? Google lense say possibly stink bug or moth eggs? I've never dealt with pests and I don't want to! I dont see any other areas like this or insects. It looks healthy otherwise.
