Collection location: Davis, California, USA [Click for map]

Who: Byrain

Specimen available

Found growing under the shade of an unidentified pine tree from the duff. The spore print was white.

I have both a dried specimen and spore print available for microscopy if anyone is interested.

Edit: Found under Cedrus deodara with redwood to one side and Casuarina equisetifolia to the other.

Annotations supplied. GenBank accession number and flat file with correct annotations received for the nrLSU. Waiting on nrITS.


I just completed contigs and haven’t submitted them.

Which I just submitted to Genbank (should be available in a couple days)

sequences in Genbank?

are the sequences in Genbank yet ?
is the best place for this material the UC herbarium or Herbarium Rooseveltianum?

Very interesting find!

Very nice to see that this species has been recollected !

We have just got back the raw data on this collection.

It is only one character different from a GenBank “proposed fungal barcode” sequence (EF080869) deposited by Dr. Vellinga of an unnamed Leucoagaricus.

We have an nrLSU sequence as well that is different in 26 characters 1.9% from a GenBank nrLSU sequence associated with the name “Leucoagaricus barssii.”

Else, would you like part or all of this material?

Very best,


Thanks Byrain,

We have received this material and accessioned it to Rod’s herbarium, It has been scheduled for DNA sequencing.

No scope so I’ll mail it out.

I have no current access to a scope, so I’ll send you the print and dried specimen I have. I’ll also see what I can do about identifying the tree it was fruiting under, at least to help broaden my knowledge of conifers.

we’ve got the genus all right…

as to species…possibly one of the undescribed members of section amanita.
you could check the spores for amyloidity yourself, or mail a fruit body to me. see my page for mailing address.
