Growing on highland cow dung.
Macro characteristic for the two mature specimens (mm):
Stem length: 30, 32
Diameter: 2, 2
Cap height: 6, 4
Cap diameter: 7, 5.5
Microscopic characteristics (um):
Spores: Av. 8.2 x 4.6. Little range.
Veil: globose, subglobose, pinched, encrusted. Largest 47um
Cheilocystidida: Av. 31.5 x 8.7. Very abundant. Lageniform / fusoid?

On a common ornamental tree in New York City, Crataegus phaenopyrum. Aecia tan with whitish tips. Straight and horn like—splitting midway to release brown finely verrucose spores. Spores 17-20 x 21-27um. Reference: Manual of Rusts of the United States and Canada—which lists G. clavipes as an option as well, but spore color and size don’t match. Spore color and size match Arthur’s description of G. trachysorum, however the spores are distinctly angular rather than globoid, perhaps because they’re still immature?
Podosphaera myrtillina var. major based on length and flexibility of appendages. On Vaccinium sp.

MLZ +ve
Crosier's -ve
Spores are bigutulate and warted
on underside of a leaf of a Phyllostachys that i think is fishpole bamboo (Phyllostachys aurea).
finally i found another locality for this pathogen. this seems to be the second known locality in NYC and one of the few in NA. i found the first one a few months ago in alley pond park https://www.inaturalist.org/observations/203896157
host plant: https://www.inaturalist.org/observations/216677993
many leaves in this stand seemed to be affected to varying degrees. photos are of one of the clearer specimens.
Found and collected by @sarahlloyd in her forest. It was an honor to be there with her.
Simocybe phlebophora?
On dead wood.
Found by @SigridJakob
Pickled milkcaps at NetCost market.
Purchased from a vendor in the Mercado de San Juan in Mexico City (stall #261). Dried and wrapped in plastic. Not
labeled.
Podospora millespora
https://www.speciesfungorum.org/Names/SynSpecies.asp?RecordID=337415
Black perithecia growing on incubated dung of Sylvilagus floridanus
Perithecial necks totally glabrous
Asci saccate, basally tapered, and appearing to house 1024 spores based on estimation and literature. Seems possible these are only 512 spored asci but those species did not match macroscopically.
Immature spores blue en masse!
Mature spores nearly black in color
Apical caudle scraggly and crooked, basal caudle is the same.
Got to species using this key
Appeared on bark taking from a living tree in a moist chamber after 2 weeks (14 days)
Living adjacent to Colloderma occulatum
Similar to Microglossum viride, but I am told it is an undescribed species.
@sigridjakob and @malacothrix have specimens for sequencing
Scale photo from my friend @bwelko. After I found the first one, we cleared out some leaves and found many more.
Could this be Squamanita
Cortinarius "falsosus-PA01"
DNA - Nanopore - ITS
ITS sequence shows it's a Squamanita but there is no close match to existing records in Genbank.
The host is Amanita canescens and is a separate entry in iNaturalist (200288206)!
Growing erumpent through the decorticated portions of an unknown hardwood stick. Perithecia not connected in a stroma. Some perithecia growing close together within “bleached” dots in the wood. Asci unitunicate, with amyloid apical plugs and with 8 uniseriate spores. Apical plug measurements: (2.2) 2.5 – 3.4 (3.5) × (2) 2.2 – 2.8 (3.2) µm, Q = (1) 1.1 – 1.4 (1.5); N = 30, Me = 2.9 × 2.5 µm; Qe = 1.2. Spores brown, 0-septate, smooth, without noticeable appendages and with less than spore-length germ slits. Spore measurements: (11.1) 12.3 – 15.6 (16.5) × (5.4) 5.5 – 7.7 (9) µm, Q = (1.7) 1.8 – 2.5 (3); N = 30, Me = 13.9 × 6.6 µm; Qe = 2.1
Moist mixed woods path beside alder swamp. Microscopy. Spores approx 28.2-31.5 x 11.9-13.1 (13.5)) Q=2.4. Vouchered. JET230716_01
It’s growing on a peach pit!! Just realized the substrate
Spores huge - micro photos at 400x (no measurements yet)
Spores citriform with apical germ pores on each end; coated in a thick gelatinous membrane. Some of the spores were singularly septate.
Seemingly 3 spores per ascus, more likely they were 4 spored and I was just not finding them.
