Agrocybe pracox group

The easiest way to file all our specimens Agrocybe praecox in the UBC herbarium is as Agrocybe praecox (Pers.) Fayod. Under any other label (not speaking about using MO numbers instead of the scientific names) the specimen will be put aside and lost somewhere at the end of the Agrocybe box, while many other “Agrocybe praecox group” collections will be still filed unrecognized as Agrocybe praecox (Pers.) Fayod. There are many cases like this when using the most modern taxonomical views would mess up filing the herbarium specimens. It might be my mistake that I consider herbarium specimens as the most important items to deal with, and MO observations only as a storage of the “virtual” information that goes with them.

However, if you type the observation number into the search bar you will find the corresponding observation much faster than if you were to search through the advanced search for Agrocybe praecox with your username. And whether or not we can come up with a better name through more work or not is not the point, its the mere fact that we will be one step closer to doing so with more work. :)

This suggestion has been here before

If I remember well, this suggestion has been here before. I have better memory for mushroom names than for the MO observation numbers. At the same time, one taxon has a single name that would go to the MO under different observation numbers.

there is a simple solution that doesn’t require the cooperation of MO users (against the design of the site).
Write/print the MO observation number on the specimen itself.

Humble request
By: Oluna & Adolf Ceska (

I would greatly appreciate if people would refrain from massing up with our MO observations names, since they are the link between the MO observation and the corresponding herbarium specimen. Your cooperation would be greatly appreciated, not only by us, but also by the UBC (Vancouver, BC) herbarium where our collection will be deposited. Adolf

Only two Agrocybe praecox observations out of 11 collections
By: Oluna & Adolf Ceska (

We have 11 collections of Agrocybe praecox from 2009 till now with only 2 MO postings. All those collections are going into the UBC herbarium and the problem with the correct (I would say “best”) name cannot be solved piecemeal. Hence, we are filing all our specimens as Agrocybe praecox to conform with the UBC herbarium naming. At the same time, we would like to keep our MO names the same as the supporting herbarium specimens, in order to maintain the link between the real specimen and the MO observation. Hence, we prefer possibly incorrect “Agrocybe praecox” to Agrocybe Species II or so. We greatly appreciate your good suggestions, but for practical reasons, we will stick with Agrocybe praecox for our MO observations.

Farinaceous smell

Is present in several Agrocybe spp., it is not indicative of A. praecox alone. I do realize its difficult to scope everything, but you’re the one who is in the best position to follow up and it would really be cool if you did.

what does that even mean?

good taxonomy requires proof.
have any?

Species concept and variation
By: Oluna & Adolf Ceska (
2014-04-28 11:47:55 JST (+0900)

In widespread species, one has to expect broader variation than in narrow endemics. Good taxonomist is one who can see the differences where they are and not to see them where they are not.
Our material will be available on the loan from the University of British Columbia in Vancouver BC, in case you want to follow this issue any further.
This particular specimen has a strong farinaceous smell that is – according to Moser & Breitenbach – characteristic for Agrocybe praecox.

as if?
that is an interesting vote.

Any chance for micro?
