Here are the photos for the "Shroomery H. ulmarius."



Decurrent gills, ellipsoidal spores. As expected, not H. ulmarius.

Still working on the two Aloha strains. I hope to have the answers in the near future!

Another grower growing the AM strain http://www.fungiforum.com/index.php?showtopic=1296&view=findpost&p=12751 - decurrent gills etc.

I am thinking thats what you will get when you fruit the AM strains you have.

Unfortunately, the problem isn't limited to the US. Here's an Austrian source:

http://www.mrcashop.org/mushroom_shop/hypsizygus-ulmarius-oyster-shirotamogitake-p-444.html

I'll bet that real European culture libraries have the genuine article. But as a non-research institution, either I don't have access to them, or they require a ton of customs authorization. The American Type Culture Collection has one, but I am not about the pay their $275 charge! And there are no guarantees that it is genuine. They get donated cultures, labeled with whatever species names that the depositing mycologist thinks they are.

so.....in Mycelium running Stamets mentioned elm oyster increasing yields of some vegetables by like 4-6-fold.....and regular ostreatus decreasing them.

wonder if this was 2 vastly different ostreatus strains in that work too?  And if you wanted to do his straw mulch thing, if that meant you actually wanted his "good" ostreatus oyster (mis-labeled as ulmonarius) rather than a true elm oyster....

what a cluster. :-(

Could you not drop the ATCC a line and ask for their view on it? They might have an ans already.

This is correct, but I had thought that the jury was still out on the Aloha genetics...

Yes, the jury is still out. I've had some delays with fruiting these cultures, but I'll get the results as soon as possible. These grow significantly slower than the "Pleurotus" varieties of H. ulmarius that I've grown so far.

Yes, LOL, the doppelganger has many "pleurotus like skills". 

Fast growth among them it appears.

stamets (and others) have also mentioned ulmonarius being far tastier than ostreatus and other oysters......

I assume that was also a reflection on their mis-labeled "super-ostreatus" rather than actual elm oysters???  thoughts?

Hey JJ,

Well, it fought cleaning up, but I now have a clean plate that I am soaking
some WBS for right now.  I should be able to post some results before
the end of Feb at least. (four weeks at a minimum).

Thanks for asking, and for sharing,

JD

According to this http://www.cncexoticmushrooms.com/p/105/461/ms23-156/beech-mushroom---hypsizygus-tessulatus ... Elm Oysters are H. Tess grown in the dark - the pic certainly looks like the contenious ones!

Then the mystery becomes what (and where ;0) are we to
find the elusive H. ulmarius?

This is the specific name of "Elm Oyster", n'est-ce pas?

It was regarding H. u. that I started this thread.

The decurrent gills were pointed out, and here we are.

Onward and upward,

JD

They are different species. I have a key from a mycology paper* which describes a different range of spore sizes and shapes for H. ulmarius and H. tessulatus, as well as some differing macroscopic features.


* S. A. Redhead, "Mycological Observations 15-16: On Omphalia and Pleurotus," Mycologia, Vol. 78, No. 4 (Jul. - Aug., 1986), pp. 522-528.

... which would also be correct if the decurrent, oyster like version was indeed H. Ulmarius!

Except that Hypsizygus doesn't have decurrent gills. The genus was first defined by Singer in 1947*. Here is Singer's description of the gills:

Quote:
lamellis adnexis vel adnatis, neque decurrentibus nisi dente inconstante, nec profunde sinuatis neque emarginatis nisi in uno latere carpophororum paucorum;


I know! It's in Latin! Singer was apparently Old School, and used Latin for the formal description. Scientific papers used to be written entirely in Latin.

Anyway, according to my best Google Translate Latin, this means:

Quote:
Gills are adnexed or adnate, but not adnate with a decurrent tooth, nor deeply sinuate, unless there is a little marginate on one side of the fruiting body.



Yes, I have become a little nuts on the subject of Hypsizygus taxonomy. :wow:

Re: Elm Oysters [Re: Terry M]

I was about to toss a block of "Shroomery H. ulmarius" when I noticed a new flush of mushrooms popping out along the edges. These look exactly like the two photos in GGMM of H. ulmarius growing from jars ( top view, with gills conveniently not shown :frown:). It's really a nice Pleurotus species -- very prolific and fast-growing. I'm cooking these in omelets for dinner.

But just what species of Pleurotus is this? Is it it's own species, which should have a new name? Something like "Pleurotus pseudo-ulmarius?" Or is it an existing species, maybe just some strain of P. ostreatus?

Anybody know of a good modern, reasonably complete key to the genus Pleurotus? I haven't been able to find one.

It is definitely a strong fruiter Terry.

I found it to be very tasty too.

BTW: I have JJs H. tessulatus on grains now.  I will
post results when possible.

JD

P.S. Do you have a copy of "Mushrooms Demystified"?  It
has keys for both Pleurotis and Hypsizygus.
