Galls growing on presumed resupinate Trametes sp.
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
Cap width is about 1.5cm

A couple growing out of a decomposing log
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.
Thinking this may be the Bay Polypore in a specimen without the dark color.
Thinking that this is bay polypore based on the shape and color, and a specimen without the darker color.

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.

With dothidiomycete/pseudotheciate hyper parasite.
Not sure on the ID given how old and junked up this was, basing it on the inrolled margin and large pores.
Immature asci and clubshaped spores
I have a few specimens of the small fruiting bodies stored in a vial but I left the main specimen in the area that it was naturally growing
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
Coprinellus 'PNW 04' growing completely submerged in flowing water on various small pieces of wood. I have no reason to think the water level here has recently risen, in a spring and summer long stream of snowmelt directly below a culvert in a considerable current, we haven't had any significant hot streak that would have raised the flow.
Overmature and mature clusters collected. Bases of the stipe seemed to have a "holdfast" adaptation at the base similar Vibrissea, see pictures. (I know they are in a different order, more of a visual metaphor)

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.
Or perhaps Paralepista? Under Pinus. Growing on buried wood and woody debris.
Hyperparasitic on a Xylariales fungus
(Second fungus was confirmed)
Microscopically, this fungus had:
cleistothecia coated in setae
IKI- asci containing 8 ascospores
Hyaline, guttulate spores that were slightly curved but not fully allantoid.
The spores became yellow in color in Lugols solution.
Seems to match Nitschkia brevispina
I believe the olivaceous KOH extractable pigments are coming from the second fungus (Hypoxylon?) growing underneath the discs. I observed two types of spores.

Leaves with mature fungus collected 02/07/2024
Chasmothecia abundant - each body encasing one singular ascus housing 8 ascospores.
Host: Betula nigra
Smooth diatrypous fruit body, very thin - like a single celled layer with no clear body.
No asci observed, possibly anamorphic.
Spores dyed in lactophenol cotton blue - only staining the apical segments
Robust
Strong green reaction to 365nm UV light when dried!
Microscopy:
Pigmented sub-globose spores
Found what appears to be conidia and conidiophores hanging out in the gills of this.
On a small hardwood branch with the bark beginning to fall away. Note the white lesions in the bark and wood beneath. Perithecia up to 1mm wide by 1.5mm tall.
Asci: 153-168 x 7.5-10µm. The spore bearing part 105-125µm. IKI+, the apical plug about 2.5 tall x 3µm wide when mature; much longer in immature asci.
Spores: 13-14 x 6-7µm, brown, ellipsoid to inequalateral ellipsoid, guttulate, usually with one large guttule at the center, with a very inconspicuous germ slit less than spore length.
On the ground in Hemlock-Birch-Pine forest. Apothecia quite small, about 2 cm tall, the head 11mm tall by 6mm wide. Asci 127-170 x 11-16µm. Spores 22-41 x 5.5-7µm, hyaline, multiguttulate, they appear aseptate, but may be immature. Paraphyses mostly straight, some curved and slightly swollen at the apex. The dimensions of the spores and asci are a little on the large size for T. atropurpureum, but I can't figure what else it could be.
Spores brown, one septate, smooth, 9-10.5 x 3.7-4µm
Asci bitunicate, clavate, very faintly IKI+, staining faintly blue over much of the upper surface, 44-56 x 9-10µm
Paraphyses septate, slightly constricted at the septa, up to 4.3µm wide at the tips.
Excipulum textura angularis
On London Plane. I think there are 64 spores per ascus (hard to count).
Spores 6.5-9.8 x 1.4-1.9µm, allantoid, light yellow-brown.
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.
No idea. Seemed like a gall wasp. There was a group of maybe 20 of them hovering over a pile of oak leaves, dipping onto the ground periodically
