Observation 68430: Macrocystidia Joss.

Another one that shouldn’t stump me, but does.

Growing in dirt and grass. I haven’t looked at it in the scope yet, but will update with any info I gather.

f. minor info: http://www.micobotanicajaen.com/...

There are only few species worldwide, I know of no single paper that covers them all. NZ has a gastroide species! Macrocystidia reducta

Macrocystidia link? Monograph? Key?

Anyone have any info on Macrocystidia, besides M. cucumis?

But didn’t make the best cross-section.

Did you look for cystidia on the gills?

A bit pale coloured, but it reminds of Macrocystidia…

Spores are white, oblong/elliptical, smooth and inamyloid.

Any ideas?

I am unable to measure spores, my scope only goes to 400x and my reticle is not calibrated.
