Observation 222322: Armillaria (Fr.) Staude
When: 2015-11-04
(47.633° 8.8333° 495m)
No herbarium specimen

Notes: “Garden” mushroom… Spore print is orange. Spores are hyaline.


I’m not really set up to photograph spores, and I have no graticule to measure them against. This is at x600 using a blue LED as an illuminator.
Spore print and dried cap. The background is white.

why Phaeolepiota is eliminated on the basis of observable macro-traits. But I think that it’s not so automatic that Pholiota should be dismissed… or Agrocybe.

Okay, here’s another guess (see proposals).

Point a camera down the eyepiece of the microscope and photograph the spores please. Also photograph the spore print too if possible, thanks.

orange spore print…hummm. All points to Armillaria. Any chance of a mistake?

Spore print is reported as orange.

This would rule out Armillaria as a possibility.
