Observation 97181: Inocybe (Fr.) Fr.
When: 2012-06-07
Herbarium specimen reported

Notes: These were growing in mixed conifers at ~ 5400 ft.
Caps were up to 4.6 cm across.
They did have an odor that was somewhat unpleasant but can’t put a name on it.
They had relatively large, smooth spores, ~ 11.0-13.0(13.4) X 7.0-8.0(8.9) microns Q(ave.) = 1.65.
I couldn’t find a lot of gill cystidia. The last photo shows a typical Cheilocystidia that looked mostly cylindrical, some with a small amount of crystals. (all based on one trial).
The only Inocybe in the Sierra Spring Fungi List that comes close is Inocybe bakeri. However, the 2010 paper by Kropp, Matheny and Nanagyulyan shows the spores as being 11-15 X 5-7 microns and the cystidia more fusiform-ventricose. Also the habitat was oak(from Los Angeles and San Luis Obispo only).
Inocybe fastigiata also has large smooth spores but the spores are bean-shaped.
