Collection location:
Tualatin Hills Nature Park, Beaverton, Washington Co., Oregon, USA [Click for map]
Who: Sava Krstic (sava)
No herbarium specimen
Notes: Growing on a stump, under falling off bark. Caps less than 1 mm.
Asci tips amyloid. Spores appear dextrinoid; is that possible?
Spore size 5 × 3 microns, but no asci are open. All Mollisia spores I’m seeing in “Swiss Fungi” are significantly longer than 5 microns. (Leaving the collection in a wet chamber to mature.)
Asci ~45 microns long. Paraphyses look simple, 1 micron thick.

turned up one highly suspect image of amyloid / dextrinoid variation from barron’s website, but the issue is not directly addressed.

Martin, thanks for the link. I also found an article (“Mollisia in Macaronesia: an exercise in frustration” by Greenleaf & Korf) where they say “One of the collections from Madeira differs from any known species of the genus in having ascospores which are dextrinoid when mounted in I solutions”. (Haven’t read the article yet; the quote is from the abstract.)
Byrain, thanks for the suggestion. I know I should start posting on Ascofrance. :)
