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

Under a log in the top layer of soil. Found what I believed to be centipede eggs. One group of them appeared to have much smaller fuzzy balls covering their surface. I thought maybe fungal, but in looking at it under a microscope it seems like they’re smaller eggs? Last photo is a magnified pic of the unaffected nearby eggs.

These aren't cup-shaped apothecia, but rather collabent (collapsed) pseudothecia in a brown subiculum.

Asci clavate, 76-90 x 13-16µm, containing 32 spores (by my approximation).

Spores hyaline, allantoid:

7.7-12.5 x 1.6-2.4µm
Me 9.3 x 2.2µm
Q=3.5-6.2
MeQ=4.3
N=23

Growing scattered in mossy, acidic soil along a cold, fast moving and rocky stream. In an oak-pine forest with a dense ericaceous understory. Near Quercus montana, Pinus strobus, Oxydendron arboreum, Kalmia latifolia, Rhododendron sp., Leucothoe fontanesiana, and Vaccinium sp. Quercus alba, Quercus rubra and Carya spp. also present in the general area. Caps inately fibrillose and hygrophanous; up to 7.3 mm wide and 2.6 mm tall. Gills adnexed to sinuate with 1 tier of lamellulae. Stems pruinose with white basal mycelium; up to 15.7 mm long and 1.1 mm wide. Surfaces not bruising. Odor abd taste not distinctive. Spores dull brown in mass. Pleurocystidia similar to cheilocustidia. Cheilocystidia metuloid and apically incrusted. Basidia 4-sterigmate. Spores nodulose. Spore measurements: (6.6) 7.1 – 8.7 (8.9) × (4.6) 4.7 – 6 (6.4) µm; Q = (1.2) 1.3 – 1.6 (1.7); N = 30; Me = 7.7 × 5.3 µm; Qe = 1.4

On incubated deer dung. Collected on Nov 26, observed on Dec 22. Small (under 0.2mm in diameter) immersed perithecia with short neck without hairs.
Asci bitunicate, 8-spored.
Ascospores 4-celled, dark brown, measured
(27.8) 28.2 - 33 (33.8) × (4.6) 4.61 - 5.7 (5.8) µm
Q = (5.1) 5.5 - 6.5 (7.1) ; N = 14
Me = 30.7 × 5.2 µm ; Qe = 5.9

Ejected spores coat the surface in the fourth picture and appear olive green/brown in mass. Asci around 150 x 5 µm the spore part 77-95µm, IKI+, the plug taller than it is wide. Spores fusiform inequalaterial, no visible germ slit, often acute at one end, 10.5-13 x 3.2-3.8µm, light brown.

Anamorphic fungi was growing directly on decorticated wood, around Eupezizella aureliella.
Conidia dark brown with many septa (phragmoconidia), measured
(52.1) 55.5 - 80.5 (86.3) × (10.2) 10.3 - 12.1 (12.4) µm
Q = (4.8) 5.1 - 7.6 (7.8) ; N = 8
Me = 69.2 × 11.2 µm ; Qe = 6.2

This is a confusing one for me. It seemingly was growing from soggy wood in a Sphagnum bog and it seemingly produced milky latex from the thin cap flesh when cut. The gills are pale yellow and dried a darker orangish yellow. Taste mild. Cap has brown flattened hairs on cap which is slightly depressed in the center. Spores are warted or spiny.

Small yellow-green single cup fungi was growing on the ground. Asci 8-spored, IKI+, croziers(+).
Ascospores are fusiform, purple, measured
(28.1) 28.8 - 31.4 (32.2) × (11.8) 12.4 - 13.8 (14.3) µm
Q = (2) 2.1 - 2.5 (2.6) ; N = 22
Me = 30.2 × 13.1 µm ; Qe = 2.3
