Observation 208533: Stropharia kauffmanii A.H. Sm.
When: 2015-07-02
Herbarium specimen reported

Notes: > A single specimen growing in the middle of the blue-blazed trail in mixed woods (both pitch pine and scrub oaks were around) in the Speedwell section of FPP .
> First I thought that I stumbled upon some weird amanita from sect. Lepidella, but the stipe was way too wooly-furfuraceous and lacking a bulb structure, the cap was scaly, and the gills had a slight pinkish hue to them.
> The spore print looks black against a white background and pink-brown when held up against a light source.
> The gill color started out as faintly pink, then gray, then dark pinkish-brown — see the pix.
> KOH on cap: orangish in the center and bright yellow close to margin.
> Will post spore pix & measurements later.

Some do not grow on wood such as S. coronilla
even has a whitish species

Thank you, all…

…for helping out with the ID! I looked at our species list from FPP and found a single unidentified Stropharia sp. listed since 2009.
I remember poking around in the soil looking for some volval material (when I thought this was an Amanita), but don’t recall seeing any wooden debris.

The gills now look pink

With pink gills it still leaves agaricus and stropharia. Some stropharia have whitish gills that get darker and become pink.

Yes, Jacob,

700 species and not a single Agaricus! I guess they don’t grow in sandy, acidic soil…

Spore print & gill color

I’ve just posted two more pix. The spore print looks almost black when seen against a white background. When held up against light, it’s pinkish-brown. The gills darkened some more, and resemble the gills of Agaricus. Maybe Pulk was right after all…

700 species and no Agaricus???!!!

When I first looked at the thumbnail I thought amanita, then after enlarging the photo I said no. Pink looking gills but not agaricus. The stem is very shaggy looking and reminds me of a stropharia stem. Why not Stropharia

We have been systematically collecting and identifying the fungi of the NJ Pine Barrens at FPP since 2009 and have documented almost 700 species, but not a single Agaricus among them!
