On peltigera

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.

Small black and other color dots in clusters on the underside of a hazelnut leaf. Fungi? Insect frass?

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.

Found fallen on Big Hump on the Duckabush trail, on the 9th switchback. Under Pseudotsuga and Acer. Altitude 300m.

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.

From the Type Locality

Very low relative abundance.

?? A patch of these was growing/blooming on top of the south jetty at Florence.
