The circle of black dots on the underside of a leaf of beaked hazelnut (Corylus cornuta)
An annual, the observation is located in the Willamette winter floodway and hightide line.
In very warm pools between Elk Rock Island and the mainland. Only saw it under one rock, but I'm sure there is more. I checked to see if it smelled of cucumbers like others I've found, but only noticed the strong odor of the stagnant water.
Larvae growing in the fruits on Lupinus argenteus (or maybe L. arbustus). The last photo shows a normal fruit, and the two preceding photos show the fruits with larvae inside.
Insect E emerged on 7/3. E1 emerged on 7/5.

A fungus turns some of the leaves red, mimicking flowers. Insects land on them and carry away spores. Host is Arctostaphylos uva-ursi.
Brian Booth State Park, near where kayaks are launched. Galls on Spiraea douglasii. The name is a wild guess.
Skeletonizing one patch of willow (Salix sp.) along the Sno-park parking area.

Galls on willow (Salix sp.)
Petiole and leaf midrib swelled
Possibly Gallformers Euura salix-petiole-gall
Leafminer on crabapple (Malus sp.)
Small black and other color dots in clusters on the underside of a hazelnut leaf. Fungi? Insect frass?
Galls on flower buds of mountain spirea (Spiraea splendens)
On Western Sword Fern (Dryopteridaceae: Polystichum munitum). Plant growing in fairly deep shade, canopied by Red Alder.

And P. ambigua.
Cyanomorph of Ricasolia amplissima (Dendriscocaulon sp.).
Dark brown rust on Pacific Poison Oak. Appears to be the first iNat record submitted in Oregon, or from anywhere in the Pacific Northwest.
Badly distorted elder leaves. I wasn’t able to find an obvious cause like aphid frass
Crushed leaves smelled like vinegar. Very small, growing in a vernally wet area beside Downingia and cryptantha. Many plants have already lost their flowers while some are in bud.
Cyanomorph of Ricasolia amplissima spp. amplissima "Dendriscocaulon intricatulum"
"Lobaria oregana" Lobaria silvae-veteris compound thallus with a primary cyanmorph and budding chloromorphs.
Interesting fungus on Pacific Sanicle leaves and stems. Tentative ID, entirely based on a couple of others on iNat, for instance:
https://www.inaturalist.org/observations/162822512
"Kellogg Scale" - found on underside of Grand Fir needles. Apparently the straw color and host are indicative of this species; looks like this is the first record of it on iNat. For reference, see p. 159:
https://essig.berkeley.edu/documents/cis/cis05.pdf
And this species is mentioned on p. 139 of Peterson's "Pacific Northwest Insects" book, which says it "feeds on needles of pines, Douglas Fir, and true fir," and can be separated by color from Chionaspis species (which are white).
Arranged in parallel rows on the underside of Grand Fir needles, always on only one needle without any on adjoining needles; several examples on branches within a few inches of each other.
cf.
On Gaultheria, always causing circular leaf spots which later excise themselves from the the leaf and fall to the ground.
Tentative ID, not sure which species?
On resin of large fallen Tsuga heterophylla. stalk about 1.5 mm max.
asci 91-110 x 6.5-8.5. Spores dark brown, 1 septate, 14.8-16.2 x 5.3-7.

Update: I think this may be Ricasolia amplissima ssp. sheiyi

On upper leaf surface of holly.
Last photo shows underside of same leaf.
Tiny larvae ( <.5 cm ) inside decayed wood, carrying brown orbs, occasionally depositing them. Is it a frass shield like in some Coleoptera larvae? Are they diptera larvae instead??
Bearing a striking resemblance to a slime mold.
Found fallen on Big Hump on the Duckabush trail, on the 9th switchback. Under Pseudotsuga and Acer. Altitude 300m.
Is a fungus or an arthropod behind this gall?
On deciduous shrub
This appears to be a green algal form of Peltigera collina. It was growing beside many other P. collina that had the typical darker coloration.
I'm not sure if what I'm seeing on the margins is isidia or lobules. I didn't see any apothecia either.
Emerging on the coldest day of the year. Certainly the first time this has been photographed.
Seperation of D. eldoradensis and D. mellifica still needs some work, especially in the Northwest, but I believe this to be the former species based on gall size and morphology.
Very low relative abundance.
Clung to the beak of a Whimbrel that was foraging in the seaweed, the bird could not dislodge it, after a couple of minutes the isopod dropped off. The Whimbrel continued to feed with the isopod on board.
