Collection location: Edgewood Blue, Wells Gray region, British Columbia, Canada [Click for map]
Who: Jason Hollinger (jason)
Herbarium specimen reported

Notes: This was a tiny cup fungus, clustered on moss in deer trail, no burn recently in this area.
FRUITING BODY: 2-6 mm wide, smooth to faintly white-powdery outside, intensely danger-orange inside, drying dull reddish orange, somewhat concave to nearly flat in age, tapering gradually but no clear stalk, margin minutely ragged
FERTILE SURFACE: hymenium clear (but appearing orange from paraphyses)
  paraphyses: long, slender, bent at somewhat expanded, rounded tips, covered w/ little granules that are IKI+ blue, no branches found, about 3.7+/−0.8 µm wide (N=8);
  asci: long, cylindrical, IKI−, no thickened tip at any stage that I found, spores 8 in 1 row packed diagonally, (190)220+/−23(250) x (11)12+/−0.89(13) µm (N=8);
  spores: fusiform to elliptic, some larger drops and many smaller drops, no texture, IKI−, (24)26+/−0.84(27) x (8.7)9.6+/−0.53(10) µm, Q=(2.4)2.7+/−0.15(3.0) (N=17)

Tried valiantly to key out in Fungi of Switzerland but I just couldn’t find anything that matched across the board.

Summary: Thanks!

Seems to be more European literature on ascos in general.

Summary: I’ve seen B. fusispora

…in Germany at a morel meeting in spring and the ascocarps looking similar and also grew on a white subiculum.

The species is described e.g. in:

  • Dennis, R.W.G. (1978): British Ascomycetes. (page 54; as Inermisia fusispora)
  • Hansen, L. & H. Knudsen (2000): Nordic Macromycetes. Ascomycetes. Vol 1 (pages 92/93)

Summary: What source did you use?

Just curious. I always run up against lack of literature when studying these things. Microscopy is always lovely, but it never gets me anywhere confidently.

Summary: Octospora leucoloma?

Just found Trevor’s copy of “Mushrooms of Idaho and Pacific Northwest: Discomycetes”, E. Tylutki, 1979. It keys out with a bit of work to Octospora leucoloma, but gives no description. There are two described in _Fungi of Switzerland, though. Spores and asci are possibly right, as is substrate.

Summary: Peziza?

I don’t think this is a Peziza, the tip of the ascis aren’t blue in the IKI, isn’t that the defining character in Peziza? Although I saw a few times where this bluing of the tips was pretty slight, and only the very tip, such that it didn’t really turn up until you color corrected the photo (to take out a yellow or red cast to the scope light).
