Bacteria? Insect?

Chenopodium???

On Smyrnium olusatrum

On Mercurialis perennis

Viburnum (carlesii?) leaf curled round in a spiral. Would it be a habitat/nest/hatching/overwintering platform for an insect? Or the impact of a pest?

Large Hook-lobed Dandelion Taraxacum subhamatum

I think the mine is on common kidney vetch, so maybe Aproaerema anthyllidella (Vetch sober)?

Growing on the side of a wall.

?
On leaf of Quercus ilex

Leaf spot on Myosotis

Host currently unknown, leaf spots with heavy infestation underneath

Arum maculatum

On cut foliage

Berberis

Exit hole in Viscum album shoot.

Asplenium ruta-muraria- I believe infected with Septoria protearum

On Trachycarpus. Unsure if multiple species are depicted (the delimited spots and the leaf tip die off)

Disease?

On a thistle, probably a Cirsium sp.

Forbidden cereal

On wild parsnip

On Lobularia maritima in garden.

Interested to know which species of leaf miner may have been at this Japanese Knotweed (or hybrid) leaf

Stem galls common on Coprosma ?propinqua (robusta hybrid?)

Located at carpark to foreshore track at Allandale

On Abies alba. Aecia 300-400 um wide, peridium tall, columnar. Aeciospores ca 36 um.

Likely a garden escapee.

Signs of insect herbivory on leaf of scurvygrass (Cochlearia sp.) plant.

White fruiting bodies on the aril of yew (Taxus baccata). Somewhere I seem to remember a similar posting but I cannot refind. The name "Monilinia" comes to mind but no reason can I find.

On Taraxacum. Upper- and lower-surface corridor, with exit slit (pupation outside mine). Very old mine.
