Hedge Nettle Stink Bug (Cosmopepla conspicillaris) is a flying True Bug in the Stink Bugs, Shield Bugs (Pentatomoidea) superfamily and Stink Bugs (Pentatomidae) family.

Stink Bugs (Family Pentatomidae) Stink bugs are among the most easily recognized True Bugs, because of their fairly consistent five sided outline. The triangular scutellum is large, extending about half the length of the wings, and is narrowed apically. Their presence is often noticed by a characteristic, powerful odor from a fluid ejected from ventral thoracic glands when the bugs are disturbed. They are fairly strong flyers, but primarily rely on cryptic coloration and sedentary behavior to escape detection. The majority are plant feeders. There are about 50 species of stink bugs in California.

Stink Bugs (Family Pentatomidae)
"Pentatomids are generally called "shield bugs" in British English, or "stink bugs" in American English. The name "Pentatomidae" is from the Greek pente meaning "five" and tomos meaning "section", and refers to the five segments of their antennae. However, the term "shield bugs" is also applied broadly to include several related families.
All pentatomids have 5-segmented antennae, and 3 tarsal segments on each foot. They generally have a large triangular scutellum in the center of the back. The body shape of adult pentatomids is generally "shieldlike," when viewed from above, but this varies between species, and is not true for the immature nymphal stages. The forewings of stink bugs are called hemelytra, with the basal half thickened while the apex is membranous. At rest, the wings are laid across the back of the insect, with the membranous wingtips overlapping. The hindwings are entirely membranous." https://www.inaturalist.org/taxa/47742-Pentatomidae

Fruiting on a fallen Douglas fir branch.
Fruiting bodies: Brain like, clear gelatinous creamy toned-but firm/hard(very unlike Dacrymyces sp).
Harvested 2 specimens.
Carefully removed a small portion of outer tissue and crush mounted on a glass slide in 3% KOH.
Spores: Globose to subglobose with many fused together and attached to long trailing jellyfish tentacle like strands/apiculus like projections.
Size: Very large.
Thoroughly dehydrated both specimens and bagged for herbarium collection/genetic record.

In the herbarium of the New Brunswick Museum

Basidiospores 3.9-5.1 x 2.0-2.6 µm, Q = 1.72-2.11 (average[51]: 4.4 X 2.3, Q = 1.92)

Pictures:
1) Fruiting bodies on the end of a birch log
2) Fruiting bodies on the end of a maple log
3) Same log as #2 but photographed in the dark to show bioluminescence
4) Scan of fruiting bodies
5) Cross section of a fruiting body showing gills. The tips of the gills have cheilocystidia with entrapped gummy material. The blisters on the sides are developing masses of cystidia.
6) Cross section of gill in Windex showing cheilocystidia at the tip and the blister-like protuberance at the upper left
7) Cross section of gills in KOH + Congo Red showing cheilocystidia and gummy material
8) Cheilocystidia in KOH + Congo red. These have protuberances, but have not yet proliferated
9) Highly branched and proliferated older cheilocystidia
10) Surface tissues of the cap (pileipellis)
11) Hypha from the flesh of the cap in KOH + Phloxine showing the pink-stained cell contents and strongly swollen gelatinous cell wall
12) Basidiospores from a spore print in Melzer's Solution
13) Basidiospores from spore print in KOH + Congo Red

I've known this rabbit since it was very young, and it has also known me for all that time. Even so, it is entirely wild, so it was rather remarkable when it hopped right in front of me to nibble the fruits of Hydroctyle sibthorpioides growing below the Japanese Maple. Enchanting.
