Observation 8059: Byssonectria cartilagineum
When: 2008-06-22
No herbarium specimen

Notes: fruiting was on an active downhill trickle of water going over moss, rocks,a hunk of wood, and little spruce pollen flowers (last seasons) remnants. The entire fruiting is about a 20 inch patch. Distance from fruiting with camera was less than 2’.The leaf in the photo is about 6-8 inches long….I did not get right down in it….errrr….ewwwwww

There is a striking similiarity and a comment I added there.
Comment is in reference to substraite in BOTH fruitings/observations.

Closest I see…

I’m not saying the stuff is dung, but there might be some dung under the mat. I’m suggesting that the description is the closest to what you have, bright orange cups 1-2 mm in diameter, and it appears to be on a mat of some kind. The mat might be damp, or cruddy from the wash it is in, so it doesn’t appear whitish. Also it is in a western montane region just after snow melt.

Looks fairly close to me… unless it is just a slime mold…

Not on dung

I am certain that the material in that photo thought to be rat dung is NOT.
It is spent pollen flowers from the Spruce trees in the vicinity. Also if those are fungi fruit bodies, they are rather tiny 3mm each in diameter approx.

Looking at PEZIZALES of the Pacific Northwest:

I was looking at the PEZIZALES key of the Pacific Northwest, because I do that kinda thing I guess, and I came accross this:

Pseudocollema cartilagineum

Apothecia minute (1-2 mm diam.), produced on an obvious mat or layer of whitish hyphae, on pack-rat dung heaps near melting snowbanks (usually montane to subalpine), bright orange in color. A moderately rare fungus, with collections from the Olympic Mountains and Cascade Mountains of WA, and high mountain areas of CA, CO, MT, and Alberta.

Now called Byssonectria cartilagineum (Kanouse et Smith) D. Pfister == Pseudocollema cartilagineum Kanouse & Smith. See 78b.

CUP 0.1 cm, spherical becoming somewhat top-shaped, soft and fleshy, produced on a thick cartilaginous stroma-like base formed over a dung heap (in the case of the type, the stroma 9-15 × 6-10 × 10 cm). HABIT and HABITAT densely gregarious on a thick tightly interwoven white to tan stroma on heap of rodent dung in spring as snow melting. DISTRIBUTION WA, AB, CA, elsewhere. MICROSTRUCTURES spores 20-24 × 8-9.6 um, elliptic, smooth, colorless, 1-seriate; asci 8-spored, 230-250 × 15-17 um; paraphyses slender, slightly enlarged in upper part.
