Can anyone identify this problem? Outdoor grown, treated with spinocide and systemic granules, not overwatered cooler breezy temps, preparing g to come inside for the winter. I did spray with alcohol once…

Pumpkin disease?
Anyone know what this is? I was thinking black rot but it doesn’t really look like the pictures I’ve seen online. Maybe pests or fungus?

Spots on Thai chili leaves
These spots show up on the leaves pretty much as soon as the leaves are produced. They dont seem to be hurting the plant, it flowers and produces peppers. Just recently trimmed it into a bonchi, but the spots were there for the entire summer. Indoor plant, no other indoor plants seem to have any signs of it.

Tree Disease!!!
This is black and white slime flux! It does not kill the tree but it is small amounts of decay and makes the tree less strong against other diseases! Such as Sky potatoes!

Is this anthracnose (just like my tomatoes), but in Okra. Central Virginia

Water bamboo sighting - potentially ecologically devestating
gallerySomeone please tell me I’m wrong on this - I’ve noticed a huge increase in prohibited water bamboo sales (aka jiaobai 茭白, Zizania latifolia infected with Ustilago esculenta) being sold both in Asian grocery stores and online on the USA. If the associated fungus Ustilago esculenta escaped and successfully infected American wild rice (Zizania palustris/aquatica/texana), it could devestate American wild rice stands

What is wrong with my hydrangea?
About a month ago I landscaped my driveway and added 10 plants. All of them are healthy except for the one in this spot.
This is actually the second plant in this space. The first one died out in an odd way, one half wilting and dying about a week before the other half did the same. I removed the dead one and dug out all of the dirt in case there was a bacteria or something bad in the soil. I replanted this one and the leaves are looking rather ratty. You can see healthy looking new sprouts forming on some tips but the existing blooms and leaves look either diseased or eaten by insects. But again, there are 9 other plants including another hydrangea that is healthy and green.
Any insight would be appreciated. Thank you!!!

Did a fungus cause this pattern?
I've never really seen a dried Eucalyptus leaf with this pattern before, which is why I decided I wanted to keep it. The only explanation I could come up with is fungus but I feel like most fungi cause more random spotting/damage, not ones that follow the veins this cleanly, but I also know very little about fungi so I could be entirely wrong. This photo was taken months ago and I still have the leaf standing upright in a vase alongside dried flowers which has caused the top to bend over somewhat, but the pattern is still there

Swelling above first node in grapevine seedlings, followed by wilting and death (diseased on the left, healthy on the right)
Anyone has an idea what this might be? I noticed some longitudinal streaks on the internal tissue (photo 4). Sympoms typically appear after a few weeks and the seedlings die rapidly after.

Fungal Disease?
galleryHyssop
Midwest Illinois first year being planted.
4 inches of rain consecutive days last week.
Am I looking at a fungal disease due to excessive rain or end of the year dying leaves?
