Aug 5, 2023. Burden Lake Rec Site, BC, Canada
Cribraria microcarpa or C. stellifera. C. stellifera appears to be the better fit based on the multiple free ends on the peridial nodes.
Growing in mixed boreal forest on dead softwood (likely Populus).
Sporocarps 1.9mm tall, with stalk 1.7mm (stalk 8.5x height of sporotheca) and sporothecal 0.3mm wide x 0.2mm high.
Stalk long, tapered with longitudinal furrows, granules 1.6-2.4um and pale with dark red center.
Peridium reduce to tiny cup (0.05mm wide, with teeth 0.03mm long) with about 10 small granule filled teeth.
Peridial net regular, branched with multiple free ends, with large round to oblong granule (dark red, 1.4-1.7um dia) filled nodes (up to 25um long).
Spores pale, 6.4-8.1um, fine warts with a few larger warts.

leg. I.V. Zemlyanskaya
see article: Bortnikov et al., 2023. Additions to Trichia botrytis complex (Myxomycetes): 9 new species.
Substrate: bark of living Bedfordia salicina. Description: several scattered pseudoaethalia, pinkish brown, 2 mm diameter. Hypothallus: membranous, pinkish brown. Peridium: fugacious, reddish brown. Capillitium: tubular, simple, looped, scantily branched, some swellings and swollen free ends. Spores in clusters of 3–8, warted, especially on outer surface, 10 µm. Notes: One collection only. (Mine has been eaten and only the hypothallus remains.)
This species is in a list of myxomycete taxa with clustered spores; considered rare (i.e. known only from 2–20 collections. (Schnittler & Mitchell 2000 ‘Species diversity in Myxomycetes based on morphological species concept.’ Stapfia 73: 55–62.)

Sporothecae globose, ~0.5mm diameter.
Stalk calcareous, white with some yellowish near tip and black at base.
Peridium with thick round limes and metallic.
Dehiscence floriform.
Capillitium colourless.
Spores brown, warted, 7.49-8.85micron in diameter, with some darker group warts.
Appears to have pseudocolumella.

Image 9-10 were taken with specimen viewed under optical compound microscope without cover slip.
Sporocarps formed on a small bryophyte-covered stump north of big tree. This is the first record of the species on this stump. The fruiting bodies didn't mature properly, possibly because of the weather and I collected them too early.
The blebs appeared on leafy liverwort (probably Bazzania), which is unusual as they seem to prefer mosses and shun liverworts.
These are blebs of a slime mould I have been calling Lamproderma 'umbilicatum'. They are forming on a small stump north of 'big tree' stump.
The mature sporocarps superficially resemble Lamproderma, but the capillitium is more akin to Didymiaceae.
It is a new genus, and is currently being described.
Growing underwater in the river at a depth of about a third of a meter. Location was almost the same as a sighting from the previous week

On dead oak (Q. agrifolia) in the notch of the attachment of a broken twig to a larger branch. Sporangia ~1.2mm. Spores of variable size, occasionally exceeding 11 µm but mostly 5-8 µm. No capilitium present.
This series of photos was taken over several days while the sporocarps were developing.

Asci: 153-168 x 7.5-10µm. The spore bearing part 105-125µm. IKI+, the apical plug about 2.5 tall x 3µm wide when mature; much longer in immature asci.
Spores: 13-14 x 6-7µm, brown, ellipsoid to inequalateral ellipsoid, guttulate, usually with one large guttule at the center, with a very inconspicuous germ slit less than spore length.
Moist chamber culture on fallen bark, possibly Gleditsia sp.; Collected September 12, 2022; sporangia about 0.5mm tall; no operculum; spores colorless, 10um, 9um x 11um; sporotheca appears frosted on top half

Found growing on small sticks and twigs in mulch.
Sitting on the surface with squirrel tooth marks on it under Eastern White Pine and Nordmann fir. Smells mushroomy, but also a bit like drying latex paint. Taste mild, pleasant but not a lot of flavor. @tombigelow suggested Melanogaster tuberiformis before I even got it home. Spores brown, 13-18.8 x 8.2-11.4µm
50-58µm x 11-15µm. Asci 185-200µm.

Edit: 2/18 Below are corresponding observations of the same log (in two pieces) that recently fell, over a period of days to see the development and changes of this in hopes to get a better chance of knowing what it is. I didn’t/don’t know if it is/was the same organism in different stages or not, but now I assume so. Today it looks as it is mature and sporing.
