Spores often truncate.
(24.8) 27.5 - 34.2 (37.4) × (11.5) 12.1 - 13.3 (13.5) µm
Q = (2) 2.1 - 2.7 (3) ; N = 15
Me = 30.9 × 12.8 µm ; Qe = 2.4

With large guttles at the poles averaging 5um in width. Smaller guttules present.

A weird one..

Microscopy showed a somewhat typical perithecial ascomycete, but the surface was composed of a thick mat of conidiophores, some of them crystalline

Spores were uniseptate, biguttulate, hyaline

Substrate: dark of sappy downed tree, smell of pickles and yellow latex, same as others? 5-15 cm diam

Habitat: Northwest Andean montane forest (NT0145)

Collectors: D. Newman & R. Vandegrift

Collection #: RLC1241

Photomicrography and molecular data forthcoming

In gallery of Xyleborinus in Rapanea. Xyleborinus beetles carry two simultaneous primary ambrosia fungi: species of Raffaelea sensual stricto in the R. canadensis complex in their elytral mycangia, and species of Dryadomyces (closely related to D. sulphurea) in the gut. These conidiophores match those expected of Dryadomyces rather than the Raffaelea canadensis complex.

Dry tape mount of the surface of Leonurus cardiaca.
Photos are a little rough. I have realized that this specimen was from foliage that overwintered under snowfall.
Leonurus cardiaca observation:

Substrate: Dead branch attached to live Ilex mucronata

Habitat: Old growth (never cut) Picea rubens, Thuja occidentalis, Pinus strobus, Betula cordifolia, Acer rubrum forest. Understorey primarily of Ilex mucronata, Viburnum lantanoides, and Rhododendron groenlandicum, Rhododendron canadense in exposed areas.

Description: Coelomycete. Stromata erumpent, pustulate-hemisphaerical-short columnar, the upper layer supporting a botryose arrangement of pycnidia, ~500mu tall, 350-550mu wide. Stroma hyaline-light yellow, basally composed of textura intricata-porrecta 2.5-6.0mu wide, becoming textura globosa-prismatica just below the pycnidial layer, cells 8-17.9x3.7-8.1mu, with the outer layer of cells becoming pale yellow. Pycnidia black, globose when young, becoming cupulate at maturity, 100-115mu tall, 195-220mu wide, with a purple brown peridium of thick-walled textura globosa-angularis-prismatica readily turning green in KOH, 4.5-11.9x3.6-6.8mu, walls 0.8-1.8mu thick. Epihymenium of pycnidia encrusted with non-cellular, yellow debris readily dissolving in KOH. Conidiophores branched, septate. Conidiogenous cells, hyaline, cylindrical, phialidic, 8.5-64.4x1.4-2.4mu. Conidia hyaline, 0-1 septate, long cylindrical, curved to sigmoid, 50.4-60.0x2.4-3.0mu, lacking appendages or mucilage.

Former names: Dermea peckiana, anamorph as Sphaeronaema stellatum and Micropera stellata

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

On Collybia nuda or Collybia brunneocephala, perethecial parasite on agaric. Spores echinulate, dark spored.
Update with microscopic characters
-->
Spores of multiple types present. All dark and echinulate, but septations varying from aseptate, singly septate, 1-2 septate, and then multi septate spores present which I think are from another species, perhaps an Alternaria. Frequently constricted at the central septation.
Most spores elliptic with a narrowed point of attachment.
Hyphae 4.7-5.5, septate, with irregular bulges. Septations regular in the vegetative growth, more sparse towards the blastic sympodial, catenulate, porogenous, terminal conodiophores.

Under Picea. Unusual out of range observation, some reddening on tapered stem, fruiting next to Hydnum sp. Strong "grape candy" odor.
Fruits 2-5.25cm across. Possibly a range extension finding. Drying quite pink. I see collections on mycoportal from North Carolina & Newfoundland, but nothing from the midwest.
