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
Under Oak amid grasses and clover.
Hardwood shrubs in mixed
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.
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. 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.
Submitted by Andrew Reed (@mossy_creek) as a mushroom lab contaminant with note:
Woody contam. 30323
Sporophores stalked and subglobose with a deep umbilicus and limeless opaque stalk
Sporocyct 437µm (0.4mm)
stellate CaCO₃ on the peridium
Capillitium is without spirals colorless with dark swellings and branched.
Spores warted 7.6 - 9.3µm
Likely C. nigra, possibly C. alta
Spores 8.35 - 9µm diameter & warted
Capillitium very elastic, sticky and growing in size.
Apothecia smaller than 1mm in diameter growing on an old oak leaf.
Asci 4-spored, IKI+, clavate, 32-37 x 5.2-6.0µm
Spores fusiform, usually with one acute end and one rounded end, somewhat curved, 9.5-15.1 x 2.2-2.9µm
Paraphyses septate with oil content. Dextrinoid in Lugol's.
Excipulum textura globulosa / intricata.
...some of my photos in Phloxine (the pinkish ones) but most in water or Lugol's.
ID provided by H. O. Baral.
Growing on Honey Locust seed pods.
Spores ellipsoid, tapering at the ends (roughly boat shaped), mostly without oil content: 7.8-10.3 x 3.2-4µm
Asci IKI-, with croziers, 66-74 x 5-6µm
Paraphyses branched, containing some refractive content. Occasionally roughened at the ends.
Hairs indicated by arrows in microphotos
Excipulum textura intricata.
Exact same location as this observation:
https://www.inaturalist.org/observations/189056021
...but four days later. Younger, fresher specimens, and showing better cap cuticle features. Smell of marzipan.
Spores warted 12.6 - 14.2µm
Peridium metallic with blue/green iridescence
Sporothecae ovate, 0.5-1mm diameter with irregular dehisence
no columella, capillitium with 4-7 meshes across and evenly calcareous.
Growing on Platanus × hispanica (London Plane)
Cortinarius 18. Hemlock birch maple. C. cinnamomeus?Ave. spore size 6 x 4 microns.

Found two specimens ~1m apart in a large Rhododendron - one (pictured) gripping the underside of a branch and the other (not pictured) gripping the edge of a leaf. Specimens sent with João Araújo to NYBG
Semi-erumpent, mixed woods. Alder, birch, oak, hemlock around.
Truffle like fungus I found on top of the dirt under a thick layer of maple leaves. Thick outer skin with geometric and circular cavities filled with a whitish semi transparent gel. Red staining around insect bites. No pronounced odor. Collected and brought home. After a few days in the fridge I cut into it again and discovered blue green tones developing from the exterior in. Spherical spores with little warts on them.
Found on a very decomposed piece of wood. Mostly deciduous forest.
Maroon color, twist and nodding head. Defined ribs
Has a very distinct odor that is citrus (grapefruit, perhaps), but with a little sharp, freshly-minted plastic from the 99¢ store smell as well.
Spores hyaline, ellipsoid, 4-5 x 1.9-2.4µm
Growing on decorticated pine in a mixed pine grove
On the wet ground under broadleaf trees.
Apothecia yellow-green, sessile, 3-4mm in diameter.
Asci operculate, 8-spored.
Spores purple, fusiform, measured
(27.4) 28 - 32.2 (32.4) × (11.9) 12.2 - 13.3 (13.7) µm
Q = (2.1) 2.11 - 2.56 (2.6) ; N = 21
Me = 30.5 × 12.7 µm ; Qe = 2.4
Erumpent. Crumbly/fragile, especially near the top.

White on the outside, light brown/tan on the inside. Found on mulch/soil. asci eight-spored, gold-ish on contact with KOH
HAY-F-002792
no asci obvious during microscopy, so is this a cyphelloid?
I believe this is Microtus californicus scat. Found in rock outcrops
Microscopy (400x):
no obvious asci
spores = round smooth. 15 x 11 µm
spines = 300-320 x 10-12 µm
