Observation 7643: Discina (Fr.) Fr.

When: 2008-05-27

Collection location: Edgewood Blue, Wells Gray region, British Columbia, Canada [Click for map]

Who: Jason Hollinger (jason)

Specimen available

asco, on side of trail, not clearly associated with any particular tree
ST: v short, essentially central, whitish like underside of cap
CAP: disk, undulating, cold and clammy-feeling, tan above, pale whitish below, smooth, 2-5 mm thick, fertile surface above
ASCI: rounded end, up to 25-30 µm wide
SPORE: 8 per ascus, ellip, ~25-30 × 12-15 µm, one large bubble in the middle, often one or two small bubbles either end though obscured by internal texture, smooth, no apiculi/appendages of any sort visible to me
PARAPHYSES: weakly and bluntly bulbous ends, colored with brown fine textured stuff, forked near ends, tightly packed, relatively thin

There were several of these “pigs ears” right on or along side the trail to the Mineral Springs at Rae Farm in Wells Gray Provincial Park. It sure looks like a Discina but according the Fungi of Switzerland that genus’s spores are supposed to have these weird perispores with bizarre “appendages” at either end, and I don’t see that at all. Beats me. Again, sorry for lack of photo.
