ITS sequence
By: Matt Gordon (Matt G)

The sequence is very close (99.5%) to 7 entries listed as M. citrinomarginata. These entries come from 5 different authors, so there seems to be a consensus about this. The sequence is about 97% similar to 2 entries (1 author) listed as M. olivaceomarginata. The very similar M. citrinomarginata sequences represent specimens from China, Tunisia, Italy, and apparently Eastern Canada and the arctic. This species appears to have a very wide distribution

You, thank you. I returned an email to you, happy to get this specimen sequenced, and I will look around that same area for more. They were growing in the grass on the banks of the Columbia River slough. These gills were purple, but the edges weren’t darker on the edge tips like the Olivevaceomarginata are….the gills were solid matte colored lavender/purple. Anyways, Let’s communicate via email from here forward….

Mycena olivaceomarginata is known to be highly variable. Even though we cannot cofirm marginate gills and the purple gill color has not been reported, I bet this name is the best we can give. The habitat and macro features we can see from the photos are good. Mircroscopy agrees as well. The spores measure 8.5-11 × 4.5-6, one basidium is 31+7 x 9, and cheilocystidia are in the 30-45 × 9-13 range. Both spores and trama (pileal as well as lamelar) react strongly in Melzer’s. Cheilocystidia have been seen forming a continuous band, and are of various shapes, variations of clavate.

Danielle, thanks for sharing part of your collection. If possible, please try to find it again and check gill edges and odor (when crushed).

I have some to send. I took spore print last night too (light colored)….it was very different from any I have seen, the lavender-purple gills with the stem and cap colors…they were pretty and different for sure….send an email w your address. danielle.strobel@yahoo.com and i will send it off.

Thanks!

Danielle, if you can sacrifice one mature mushroom from this collection, I would scope it. This looks like an interesting Mycena, with unusual colors for its shape.

Thanks,

Sava
