No specimen available

Small pink-scaled Agaricales. Gills white, free. Stipe with sharpish pink scales reminiscent of Pholiota.


Bare remnant of annulus visible on stipe. Pink scales below annulus.
Overall cap color pink with reddish highlights, some white showing through scale cracks.
After extensive hunting, found the specimen again today. Have not sliced the cap yet. Surface appears to be much more brown today than yesterday.

NAME ORIGIN after French mycologist Marcel Josserand
SIMILAR Lepiota subincarnata is pinkish hued (Arora); Lepiota subincarnata has cap 1-3cm, almost tomentose, very finely punctate scaly, pink, the disc pink-brownish when old, stem 2-6cm x 0.2-0.5cm, upper stem white, but below the indistinct ring zone, the stem colored pink, at base with scaly veil zones, habitat deciduous and coniferous woods, spores 6-8 × 2-4 microns (Moser(1)), Lepiota helveola has a more membranous veil and larger spores (according to Moser, but note his spore measurements are larger than some)

None match this obs. Most don’t show scales on the stipe. Most have a predominantly brown center for the cap. None that I have found shows a pink-scaled Lepiota with red tips of the cap scales.

No bands of scales on the stipe, Else.
By: Daniel B. Wheeler (Tuberale)
2012-11-20 21:13:44 PST (-0800)

Once I saw the scales on the stipe, I was VERY careful not to remove any of them. They were scattered, and not very abundant: as you see them in the photos. I didn’t bring the mushroom home, so can’t consume it. Thanks for the warning, though.

I do plan on returning tomorrow to take more photos. Unfortunately my camera saves JPEGs on floppy disk, and my sole disk was full with the second photo of this.

It really is/was a beautiful little critter. I would say not over 3cm across the cap, and perhaps 7cm from the base of the stipe.

From the images I was able to find of L. subincarnata on Google, this obs. doesn’t appear to be a match. It is too small, has almost no scales that are ochraceous in the center, nor brownish-red as one description states. It lacks the whorl-like rings of scales another description gives. All I have to go on is the descriptions. I do not believe I have found this species before. However, as small pink mushrooms go it is rather pretty IMO.

most likely L. subincarnata

The colours are right for L. subincarnata, and so are the other colours of the frb. The scales on the cap are ok. the bands on the stipe have partially been rubbed off by handling.
don’t eat this.

pink goes nicely on Lepiota.

“Pink and Lepiota don’t go together well in my experience.”

I’ve only sorta suggested L. subincarnata and I haven’t voted anything else down.

Thanks Richard and Britney.

Richard: I changed the notes now.

Britney: The examples you gave do not match the pink with reddish points in this obs. Also, your obs. gills seem more crowded than this. This obs. looks different than your citations. I don’t see the pink, except in the sectioned stipe.

look at notes below the obs. title.
you can change it by clicking on “edit observation” up top.
i’ll change my vote then, perhaps…

I did, didn’t I?

And I have no way to change my error now. Except, perhaps, by noting my mistake here. Sorry, Richard.

I originally didn’t consider Lepiota because of the cap color. But after Britney suggested it, I checked Arora’s key. The lack of much of an annulus seems to be an important factor here. The annulus appears to have stayed with the gill edges as the cap expanded, as I think there are remants on the cap edge.

I’m pretty certain I haven’t found this before. Pink and Lepiota don’t go together well in my experience.

I agree with Britney…

in your notes you call the gills adnexed.
i didn’t make it up.
if the gills are indeed free then it very well could be a Lepiota.
i’ve never seen anything i would consider a Lepiota with anything but…
you never know.

I agree with Britney.

Gills here appear free, at least to me. I can go collect the fungus and take more photos, just for certainty.

While Arora says this is saprophytic (growing from woody debris) I did notice a Douglas-fir cone adjacent to the fungus, but separate from it. Could be growing from cone debris as well that I didn’t see.

adnexed gills

2012-11-20 14:04:50 PST (-0800)

I felt it was a reasonable suggestion based on this:

GILLS free or adnexed, close; white to creamy yellow, not bruising” (Arora)
HABITAT on lawns and in woods” (Sieger) “deciduous and coniferous woods” (Moser)

Are the gills really adnexed here?

adnexed gills…

likely not Lepiota.
Daniel, did you get a print?

Thanks for asking, Britney.

It was found on lawn. But it was also found under a larger Douglas-fir, which suggests a possibly mycorrhizal association as well. No woody-debris observed.

Lepiota josserandii

Where these found on the lawn? Where the gill edges pink at all?

Edit, wiki says Lepiota josserandii is synonymous with Lepiota subincarnata.
