Observation 146910: Amanita suballiacea (Murrill) Murrill
When: 2013-09-28
No herbarium specimen

Notes: Common destroying angel seen in Wisconsin. Too robust to really call Amanita bisporigera but is KOH + thus probably ruling out A magnivelaris. Description for “Sturgeon’s Destroying Angel” seems to fit best. Reports of it by Wisconsin Mycological Society members over the past couple of forays and it’s usually pretty commonly seen this time of the year in Wisconsin.

The sequence should be public in about a week.

The GenBank accession number is KX810033.

Thanks, Britt.

Very best,

Rod

We have some additional data.

We obtained part of the nrLSU sequence. The nice part is that it extends into a region not available from other nrLSU sequences for suballiacea posted in GenBank (a rather conserved region that is of limited diagnostic value). The bad part is that both the nrITS and nrLSU of this species are heterogenous sufficiently to have caused us to have a gap in the nrLSU data in this particular case. This may be addressed by using some additional sequencing primers. We have obtained the region in question in suballiacea in the past; so it’s likely we’ll get it again.

Very best,

Rod

You’re welcome.

No garlic smell noted…

And I’m very familiar with this species; it’s our most common destroying angel in the Upper Midwest, indeed it’s one of our most common Amanitas in late summer thru fall. I’ve never noticed the odor but will make it a point to do some close sniffing this year. Come to the NAMA Foray in WI next year and you’ll get to sniff for yourself!

did you smell that distinctive garlic odor, Britt?

Very good to know, thanks!

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