They're back! Andrena males were busy lekking at this location. Nice, sunny and warm spring day. Occasionally, the bees would briefly set down for a rest from their circling. No females observed. Photo 3 shows the habitat.

Epiphytic lichen on Corylopsis pauciflora (buttercup winter hazel).

Photo 1. Closeup in situ.
Photo 2. Same lichen shown in association with the mustard kidney lichen.
Photo 3. 0.7x underside showing veins and rhizoids.

According to Macrolichens of the Pacific Northwest (McCune and Geiser 2009), P. collina "is the only lichen in the PNW with veins below and sorediate". McCune and Geiser 2009 also state "apothecia black on raised narrow lobes", but the one apothecia present on the lichen looks orange to my eye. Do others have thoughts as to why this might be?

Lastly, I am used to seeing this lichen with more of a brown colour, but this one is more greyish than brown.

Epiphytic lichen on Corylopsis pauciflora (buttercup winter hazel).

Photo 1. In situ.
Photo 2. Underside.
Photo 3. Apothecia.
Photo 4. Soridia.

According to Macrolichens of the Pacific Northwest (McCune and Geiser 2009), the apothecia are "uncommon".

Milner gardens is a good place to visit if you want to see tree lungwort in situ because this lichen covers many of the rhododendrons at eye level (as opposed to up in the tree tops).

This lichen and the three other species (Peltigera collina, Nephroma laevigatum and Sticta limbata) on the hazel are a lovely memorial to Tara (see lower right of photo 1).

Plants growing on rock in a water filled ditch beside the rail line.

Photo 1. 0.7x plant tip. Leaves variable from entire to weakly lobed (emarginate). Leaves lower on the stem tend to have a weak double lobe.
Photo 2. In situ.
Photo 3. Habitat.
Photo 4. 5x Small branch which still has two intact under leaves.
Photo 5. 20x One under leaf that is a bit worse for wear.
Photo 6. Leaf cells showing oil bodies and thin cell walls without trigones.

The variably shaped leaves fooled me, as I thought at first this plant was Lophocolea heterophylla. However, the habitat was wrong. I was saved by "How to Know the Aquatic Plants" (Prescott 1969) that suggested Chiloscyphus. Further research indicates two species in the local area: polyanthus and pallescens. The latter is apparently associated with bogs so I am going with polyanthus.

Woe to the person who does not know this species has under leaves as most under leaves were absent - broken off and/or replaced by the rhizoids. I had to resort to looking on the underside of a very small side shoot. Patience paid off when I was finally able to capture an image - albeit not a perfect image as the under leaf was slightly damaged.

Bees were nesting in the ground. There were about 4 to 5 nest entrances. Female bee was carrying tree needle into the nest. How she decided on that particular needle is a mystery since needles were everywhere on the ground. Aspect is full south sun.

Anthropomorphic soil from a suburban housing development. Ground flat.

It was very challenging to get any photos because this bee species is very fast flying.

Southwest facing 30 to 60 cm high bank beside trail. Number of nests were not counted, but I estimate more than 10 nests. Very hot afternoon and bees were very active.

Photo 1. Female bee that had backed out of her nest.
Photos 2 to 4. Showing same female backing out.

Soil was very sandy. Bank almost vertical.

Previously I had thought Diathidum were not ground nesting, but this species apparently is. That being said, when I did a literature search, I found only one reference to this species nesting in the ground (2 nests were observed). So it is good that there are now additional evidence of ground nesting behavior.

According to Sheffield and Heron (2018), Dianthidium subparvum is the only Dianthidium species located in the local area i.e British Columbia Pacific Maritime.

Plant growing in a ditch located next to a railroad line.

Jenkins (2020) states C. giganteum "is one of several swamp mosses whose shoots die when submerged in the winter and then produce new growth when the water level drops in the spring." I can attest to a very bad mouldy odor from the moss, perhaps from it decaying.
