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).

Sometimes a microscopic slide mount may not look too interesting. The first one looks boring and confusing but in fact shows many important features (conidia, nematode carcasses filled with mycelium and attachment pegs). After consultation and further photos it was included as the first record for North America (Baral et al., 2020). The only way to learn is to send photos. They may be more significant than you think.
Lecophagus vermicola Magyar et al. On branch (Populus sp) attached to live tree heavily colonized by old Hysteriaceae. Lecophagus observed close to Orbilia sp. Conidia canoe shape with upturned ends, 5-7 septate; meaurements in water mount 52-73x15-19µm not including upturned ends which measure 10-12µm long therefore total of 63-90x15-19µm. Stored in cold garage overnight and reobserved in lacto blue mount showed a reduction in width to 12-15µm probably due to death and lacto blue mounting medium. Photos with dark blue conidia taken in lacto blue mounting media. All others in water. Note the internal hyphae in dead nematode and “sticky knob” on outside surface of nematode.
