Observation 5240: Melanoleuca exscissa (Fr.) Singer
When: 2007-11-25
No herbarium specimen

Notes: Spores 7-9 um, amyloid with small warts.
Cheilocystidia septate with a dot in the middle of the septum and some with Inocybe type encrusted crystals on the apex.

Very similar or the same as M. utahensis. Mycologia 69: 927-951. However, the key and description lacks the clarity of Bas, et al.

I have reached the same conclusion regarding the id — my collection was on 2007-11-20.


Considering htat the Genus is in a dire need of a complete rewrite, the sources available to me, plus the microsocpy suggested strongly M. exscissa. I see the same septate cystidia.

Now on to the other Melanoleuca spp.
