Growing on the sides of a fallen Acer (?) trunk in a grove of Rhododendron maximum. Acer spp., Betula sp. and Hamamelis virginiana nearby. Hymenium easily peeled from substrate. Margins fimbriate. Strong chemical odor. Spore print white. All structures inamyloid. Rhomboid crystals abundant in the hymenium. Monomitic with clamps. Gloeoplerous hyphae present. Cystidia absent. Basidia suburniform and 6-sterigmate. Basidia measurements: (14.6) 16.2 – 21.9 (25.1) × (5.7) 6.2 – 7.7 (7.9) µm, Q = (2) 2.3 – 3 (3.8); N = 26, Me = 18.8 × 7 µm; Qe = 2.7. Spores smooth, hyaline and thin-walled. Spore measurements: (6.2) 6.7 – 8 (8.7) × (2.6) 2.7 – 3.3 (3.7) µm, Q = (2.1) 2.2 – 2.6 (3.2); N = 30, Me = 7.4 × 3.1 µm; Qe = 2.4.
Dead standing deciduous tree, possibly sugar maple
In lawn with lots of moss
After killing frost, first snow, melt then warmer weather

There is lots of Tricholoma terrain in our lawn but it is usually much bigger. These are just 2-3 cm across and more placate .. perhaps a post-frost from?
Hardwood stand, Fagus, Betula, and Acer. Growing on Betula.
Growing on Coprinus comatus that looks a lot like Entoloma abortivum aborted stage. Grassy lawn. Last picture a week later.
Collected unintentionally with a mushroom:
https://www.inaturalist.org/observations/186989225
The mushrooms pictured in situ were not the ones collected but were growing beside the specimen collected, on which the mold did not appear until spore printing. The mold pins fell around the outside of the mushroom creating black specks on the foil which could be scraped onto a slide. After printing the mushroom cap was placed in a jar to continue to let the bonnet mold grow. Some of the fruiting bodies were then collected from this.
The spores were fairly opaque and whitish grey under the microscope and measured 30-34 x 8-11 µm. However when Melzer's reagent was applied they stained deep yellow with a thick, hyaline wall becoming distinct in some specimens where previously it had not been noticeable. As such the spore size might actually be a bit larger. Some spores were almost dextrinoid in their darkness with a yellowish colour that bordered on brown. Aniline blue did not result in noticeable colour change.
Assume from last fall, 6 of them on a ridge where the older stable dune meets a small wet area, mixture of rush/sedge/marram grass, sandy soil. 20-30mm tall, cap 7-10mm wide, stipe 2mm wide, opening 1mm wide, raised up 0.5mm. Warted spores, 4.1 x 4.7um. Spore mass salmon in colour. Capillinium 3.52-7.65 um wide, up to 10um at the septa, which are stirrup like shapes with a yellow tinge in KOH. Last two pictures are of what I thought might be the crystals on the capillinium mentioned in literature, but certainly not 'encrusted' as some descriptions say.

growing on very rotten wood of American Beech (Fagus grandifolia).
Completely stumped with this one, not even sure in which class of Ascomycetes this belong (Lecanoromycetes? Dothideomycetes? Eurotiomycetes? Leotiomycetes?)
ascomata isolated, maroon, to almost black numerous on substrate, waxy, rather though, about 0.2 - 0.4mm in diameter. Asci contain 16(?) spores, altough sometime the spore appear to be somewhat attached together. Asci thick walled. Spore aseptate, hyaline, probably smooth, subglobose or somewhat ellipsoidal measuring 4.5 - 6.5 µm X (3.5)4 - 5(5.5) µm. (Avg 5.3 x 4.5 µm). Thin hyaline paraphyse-like structure present, but hard to visualize. fruit-body appear covered in dark orange poorly defined incrustation.
First P. arenulina found this year, several patches on the west side of South Rustico dunes. Due to Fiona damage these are growing in very shallow sand, only an inch or so above cobble, so the stipe was not buried as much as normal.
So tiny, very fresh, thought they might be something else, but the amyloid spores and fuzzy foot, point to Xeromphalina. Growing on old stump, likely hemlock, along a small stream. Largest cap was 8mm wide. Generally we consider X. campanella our species, but genetic work done in NFL and Quebec have all specimens sampled as X. enigmatica. It is probable that this is X. engimatica, can only tell via DNA sequence unfortunately.

SPECIES NAME: Moellerodiscus advenulus (Phillips) Dumont
COLLECTIONS DATA: AC 2417, 2487. Auburn woodlot June 2020, 2021
SPECIES DESCRIPTION: ascomata translucent with orange-yellow to green "sphaerocysts/cells" on the stipe; asci blue in Lugols; spores 7-9x2-4um with gel appendages
NOTES: Seems to be widespread on Larix sp needles in June in the litter beneath trees. An excellent description is presented by Fallah & Shearer (2001) and the Freshwater Ascomycetes website. Some excellent photos are found on ASCO-SONNEBERG website as Calycina/Antinoa spores a bit larger and no apparent appendages. There is a R.F. Cain collection (Phialea advenula) near Norwich Ontario on Larix needles RF 2761 annotated by KP Dumont in the NYBG on Mycoportal. I assume the rest of the material is in TRTC. The best generic name for the species is not clear. The latest treatment discusses its placement in Lambertella (Zhao et al. 2016).
