Growing on wood lying on the ground.

Spores:
fusiform-clavate, with the upper end acute and other end rounded. The spore body a long, sometimes winding form ending at the pointed end of the spore:

The spore bodies: 2-4µm in length

Asci:
22.9-27.7 x 3.4-3.9µm
truncate apex, furcate base. The spores at the top of the asci with spore bodies oriented down. The spores lower in the asci with spore bodies oriented upward.

Paraphyses:
capitate, with glutinous material covering the apex
19.8 x 3.1µm

Growing on an herbaceous stem that was embedded in mud.

Excipulum textura prismatica/intricata

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.

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

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

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:

...but four days later. Younger, fresher specimens, and showing better cap cuticle features. Smell of marzipan.
