Collection location: Auckland, New Zealand [Click for map]

Who: Michael W (Michael Wallace)

Specimen available

Notes:
This beautiful Lepiota species was found in native New Zealand forest in soil and leaf litter under Kunzea ericoides, Cyathea dealbata and Cyathea medullaris.

I am not certain that this is L. magnispora, it was the closest name I could find!

Pileus: 20-50mm in diameter. Conic to plane and slightly uplifted with maturity, with a broad umbo. Margin adorned with remnants of a fibrillose partial veil. Colour white with light brown floccose patches.
Stipe: 50-100mm long by 5-8mm in diameter. Even to slightly enlarged at the base, pruinose. Colour dingy white.
Lamellae: Attachment free. Close to subdistant. Margin eroded. Colour white.

The spores are a good match for L. magnispora in size and shape but the description I have read mentions that cystidia are absent, these specimens exhibit abundant cheilocystidia!

Forgotten detail,

One detail I failed to mention, the specimen in the fourth image down seemed to be fruiting from what looked like a sclerotia, it was about 40mm in diameter and the flesh is brown, it broke when I made my collection and the inside can be seen in image #17.

Thanks,

Thanks for the confirmation Else, I was right the first time.
Thanks Joshua for clearing that up for me, I guess you can’t trust everything you read on the internet!
I have received your messages and have dried specimens of all my finds that are relevant to your study, I will send them as soon as possible, I would like to keep part of my collections for my herbarium collection but will send you some well dried and hopefully well preserved specimens!
Regards,
Michael.

And to clear things up L. magnispora has abundant cheilocystidia…

close to, or identical with, Lepiota magnispora

The shape of the spores (plus of course the general appearance of the fruitbody) point to Lepiota magnispora or thereabouts. Definitely penguin spores (and not the plumper spores with a curved back as in L. clypeolaria). Very nice to see all the microscopic details!

I agree,

I will change it to Lepiota sp.

Hi Michael,

There is no record of this species been found in NZ before so I to would have my doubts. On the other had as this genus has never been studied in NZ before who knows what here.
