Observation 129291: Lepiota (Pers.) Gray
When: 2013-02-22

Notes: While cruising for Boletes in the Cooloola Sandmass, just south of Fraser Island, Nigel Fechner and I ran across this Lepiota with greenish yellow lamellae.

Roy Watling & Norma Gregory wrote a series of papers on the Boletes from Cooloola, so that’s why I’ve been collecting here. Last specimen written up last night was this lovely Lepiota. Not having access to anything remotely called taxonomic “literature” while in the field, this name is the best we could find.

Recognized by sight: Greenish yellow lamellae. There is a fragile white partial veil, and there are darker brown squamules below the PV to the base of the stipe. Here are the macroscopic notes:
Pileus 1.5-4 cm broad, convex to plane, dry, subtomentose becoming areolate with flattened felty scales toward margin, cinnamon brown to cocoa brown (6D-E6), sometimes with sterile, white velar remnants at margin. Flesh white to pale greenish yellow, unchanging, with mild odor and taste. Lamellae free, greenish yellow (1B7, 2A6,5), close, with even margins. Stipe 2.5-4.5 cm long, 3-7 mm broad, equal with a slightly bulbous base, dry, with collapsed annular veil, subsquamulose scaly below, pale cinnamon brown above, darker cinnamon brown below, white at base, with interior white, pithy, becoming hollow, with pale greenish yellow rind.

too bad, but still interesting

so now it looks more like L. elaiophylla or something close to it.
there are not many species of the genus known from Australia, so every one counts!

now Roy…

you mean that just the “micro” Wow factor was nil. That macro makes plenty of Wow, all on its own…even if this mushroom won’t give up its name so readily.

Not Verrucuspora

The WoW factor was nil. Got access to a microscope in Brisbane today and the spores are smooth, ellipsoidal. Oh well . . . that doesn’t help with the ID too much, but it avoids the nomenclatural rat’s nest surrounding Verrucosppra. Thanks for all the input.

Thanks

Danny. Now I know what to look for, but have no microscope.

BTW, Verrucospora verrucospora is a tautonym, not in good taste according to the ICN.

along with a PDF of the Horak article in which the genus was typified.

Very cool

Else! Thanks for that bit re: the spores. I’ll certainly have a look first thing when I get home.

another possibility:

Verrucospora vulgaris – check the spores – and if they have a very high ‘wow’ factor, it is probably this!

wow.

looks like the collecting has been good in OZ!

Thank you both!

Please keep me informed about the result. Thx!

Else for that. I’ll be happy to look at spores when I get back to NY and the specimens make their way across the Pacific. There is sufficient material to share if you like. Again, thanks for the input.

Lepiota xanthophylla is European

and the name L. xanthophylla has been applied to two taxa, one in greenhouses in Europe that contains amatoxins (now named L. elaiophylla), and in Orton’s original sense, a native European species with a dark brown pileus and lacking the olivaceous tinges.
This one could be L. elaiophylla, but i think that it is more likely to be a different species altogether. There are reports of L. elaiophylla from South America.

Could you have a look at the spores?

I found the same

in Blackheath, New South Wales, in 2007. But I am afraid I did not preserve it. Will post the pictures somewhen.
