This species doesn't have a name, yet. It is a new and undescribed amoeba. So far, it has only been recorded at one location, a rain-fed bog lake in Ottawa. The shell is usually six-sided, with a flat top and nearly perpendicular sides. It has a ruffled (crenulated) aperture. They are usually found in floating mats of filamentous algae.

Sixth image is a stack that didn't work as well as I'd hoped.

This specimen is NOT populated with symbiotic algae (thus the absence of green coloration). The arrows in the first composite photo indicate the long (black) and short (red) populations of bifurcated spines. The long spines have a deeper fork than expected and may indicate this is a variant of A. turfacea or a different species. (https://arcella.nl/acanthocystis-turfacea/)

As seen here https://arcella.nl/actinophrys-sol/. In image 2 (composite) the left panel shows a large contractile vacuole, at the cell surface, that is about to burst. The right panel show remnants of the same vacuole immediately after bursting. The vacuole then quickly regenerated. This sequence is captured in the attached video (and was repeated continually, giving the vacuole the appearance of little engine). -https://youtu.be/h9yUcYSc16Q - My understanding is that A. sol is managing osmotic balance by expelling water with this contractile vacuole.

Large, tetrahedral, asexual ascospore of an aquatic hyphomycetes fungi (known collectively as Ingoldian fungi). Compare the current specimen with a smaller example from a previous observation, https://www.inaturalist.org/observations/105817766. These are often involved in leaf litter decomposition. Using Oliver Kim's (MicrobeHunter) video about "focus stacking" and the free software described, Picolay, I performed my first stacking experiment https://www.youtube.com/watch?v=4reipg9LV8M. Image 1 is a stacked image. Image 2 is a composite of the 6 photos that were focus-stacked, using Picolay, to create the first image. Considering that the focal planes represented by the 6 contributing photographs are too widely spaced (i.e, truly need more intervening images), the result is impressive. I hope to play with Picolay again soon!.

Black, spiky fruiting bodies (like beard stubble), about 1-2mm long, were found on a dead, fallen branch. The spikes were stiff and prickly when handled. The spikes protruded through tiny fissures in the bark and were distributed in clusters over the entire ~60cm (~2') branch. The spikes were present on "bare" bark and also growing through lichen colonies (as seen in photos 1 & 2, where they protrude through a colony of Star Rosette Lichen). Far less frequent than the spikes were small, black, flat-topped, mushroom-shaped bodies, looking like tiny nails driven into minute fissures in the bark (esp. photos 6-9). Their caps or heads were only 0.5 to 1mm in diameter. (I noticed them only in the photo enlargements.) It is my assumption that these structures are related to the spikes. This fungus looks similar to images of Caliciopsis (e.g. Pine Canker, however, I don't know if this branch came from a White Pine that is within about 10 meters of the drop location, or from one of the other nearby trees (including oaks, Big Tooth Aspen, Black Cherry, and Red Cedar).

3 specimens were photograph, each presented in a different image or image composite; I'm assuming they were all the same species. All were essentially oval and ranged 60-70µ in length. All had a large oral cavity (but not the huge cleft of Lembadion?). The oral cavity appears to contain an oral sail (like Pleuronema) that waves about, (best seen in the video), though I could not detect any movement of a sail beyond the bounds of the oral cavity. There appear to be 2 types of cilia, both of the same thickness: long (few) and short (many). These are easily seen in the first image. In the 3rd composite image (depicting the the smallest of the three specimens) the photo sequence records the opening of the oral cavity from a closed state ... very cool! I wish I caught the mouth opening on video, but it's still fun to view: https://youtu.be/JgQ9JYRjFBw

I think this is an early stage or late (degrading) stage of Actinosphaerium development. The axopods (1), and large vacuoles (2), and streaming ectoplasm surrounding the vacuoles, are all characteristics of Actinosphaerium... just sparsely represented. Actinosphaerium-lite or a flyweight division contender. A video of this specimen is found here: https://youtu.be/oXElITiowuk
(video description: Large, multi-vacuole Actinosphaerium (250 - 850 µm) were common in the 12/27/2021 water sample. This specimen retains representative features of Actinosphaerium, though very few in number. It has only one axopod (internally supported by microtubules, stiff; unlike the lobose and filose pseudopodia); it has only 2 large vacuoles (vs many vacuoles stacked in concentric layers); it has an ectoplasm that seems to stream around surface of the vacuoles. I do not see a nucleus, but imagine there must be one here. Interesting!)

A ciliate that resembles an Easter egg. This one was found in a natural pond intermittently connected to the Gatineau river by a culvert.

The colourful cytoplasm consists mainly of food vacuoles containing cyanobacteria in various phases of digestion. The cytostome (cell mouth) is supported by a cytopharyngeal basket composed of stiff microtubular rods (at the anterior right, from cell's perspective). The cell has numerous spindle-shaped trichocysts, visible here as short black lines.

Even at a whapping 250µ, this is the smallest Actinosphaerium sp. sampled from this location on 12/27/21. It has a large number of axopodia and so must be on the hunt. These organisms are multi-nucleate. Perhaps because of the smaller size of this specimen, the nuclei are more readily seen. In the last image I've labeled what I think are nuclei.

D. archeri?, though I'm confused by the presence of two cell types. The larger, cyst-like cells appear to be intimately associated with the colony, but do they derive from D. archeri (cysts for long term survival?) or are they parasitic or epiphytic cells exploiting the Diplophrys colony? I could not find a literature reference regarding the ability of D. archeri to form cysts.
The first 3 images provide a close-up view. Images 4 - 9 were taken periodically over a ~9 minute interval as the colony consolidated. The YouTube video spans this same time interval (5, ~15 second videos catenated in a single video): https://youtu.be/ZJ2OV10jLvU.

Uncertain about the ID. Also seems similar to Stigonema, though this particular specimen is unbranched. Urospora and Ulothrix are also a possibilities. Please help if you can. Thanks!

Often attaches by tip of posterior flagellum and has a distinctive kicking or bouncing movement. Genus was narrowed around this species, most other accepted species went to the related Neobodo.

Test of an amoeba, I think... coarsely granular with a dramatically flared aperture (assuming the aperture is on the left side)... could not finda match for the shape here https://www.arcella.nl/lobose-testate-amoebae/. Could this be a foram?

UPDATE: This looks very much like the test of marine filose amoeba, Ogdeniella elegans with its funnel-shaped, flared aperture; see figures 30 & 31 here https://www.researchgate.net/publication/259501265_Shell_Morphology_Biometry_and_Distribution_of_Some_Marine_Interstitial_Testate_Amoebae_Sarcodina_Rhizopoda/figures?lo=1. The habitat is correct for this species.

Small (5-8µ), highly motile, marine flagellate with one flagellum forward and one aft. Because of the small size, ID possibilities may include Cryptomonadida (corrected) and Kinetoplastida as described here https://www.researchgate.net/publication/263457365_Heterotrophic_flagellates_Protista_from_marine_sediments_of_Botany_Bay_Australia.

Eucampia zodiacus Ehrenberg 1839

Live images of the marine diatom Eucampia zodiacus Ehrenberg 1839. Class, Mediophyceae; Subclass, Chaetocerotophycidae; Family, Hemiaulaceae. E. zodiacus is the type species for this genus (Guiry & Guiry 2021).

Girdle view. Only five species of Eucampia reported (Round et al., 1990, Guiry & Guiry 2021). Cells often form flattened chains by interlocking the two short apical elevations (horns). The wide apertures between valves may be elliptical, oval, angular elliptical to square in outline. Valves are concave between the two elevations. The labiate process (rimoportulae) is centrally located on the valve. Helical-spiral chains form due to small differences in growth of the valves and girdle. Chloroplasts are round to ovoid bodies.

Eucampia zodiacus is a cosmopolitan marine centric diatom species, not reported from polar regions. Frequently found in plankton samples from Trincomali Channel, Galiano Island, BC., Canada.

Methods:

From marine plankton collected in the Trincomali Channel, Spanish Hill Wharf, North Galiano Island, Gulf Islands, British Columbia, Canada, May 25, 2021. Live sample. Nikon TE300, 20x, 40x oil DIC NA 0.90.
