Observation 157351: Morchella rufobrunnea Guzmán & F. Tapia
When: 2014-01-07

Notes: Collected from a planter with woodchips and rose bushes. Was quite a surprise – my first morel.

Recognized by sight: habitat, stature. The cross-ridges don’t seem regular and ‘ladder-like’ enough, nor does the hymenium seem dark enough for M. importuna

I understand. Good luck with your massive sequencing project…

I really shouldn’t

I have hundreds of collections I need to sequence and only two weeks to do it.

Nothing wrong with adding just one more…

What is stopping me?

I have so many of my own morel collections to sequence. I shouldn’t really be asking for more to arrive in the mail.

So, what’s stopping you, Alan? Unlike other genera, molecular phylogeny of morels has been studied exhaustively, so it will be $ well spent. Both you and Debbie stand your ground, so ask Kevin for a sample, submit if for sequencing/annotation, split the costs, get your satisfaction, and contribute to science at the same time. End of story. :-)
Hey, maybe both of you are wrong and it’s a new species. ;-)

Anyone can do DNA analysis

You can just send it to alvalab.es and give them $20.

I don’t see any Morchella importuna on Kuo’s site that do not have ladder-like pits.

exhausting to read or write? ;)

at any rate, that is a good suggestion, to do the DNA. go for it Alan, since you are the one who can actually do it!

in the meantime, check out the many many photos of importuna that do not have “regular” laddering … some that were DNA confirmed, on Kuo’s webpage and here on MO.

Just get a sequence!

Hey, there is a sample here. Spend a few bucks on a molecular sequence and get a definitive answer – problem solved. Trying to argue morphology from pix eventually gets exhausting. :-)

This is clearly M. rufobrunnea

Doesn’t look anything like the ladder-like pits of Morchella importuna.

one last attempt at a reasoned ID here …
By: Debbie Viess (amanitarita)

rufobrunnea starts out with pale ridges and very dark pits; it then becomes blonde in color. plain brown is not a color choice for this species.

other importuna examples, from here on MO to on Kuo’s website, show a variety of brown colors as well as somewhat random cross-barring, but always vertical pits.

both occur in wood chips.

which features shown here best match one of the two possible species: brown color, vertical pits, cross-barring, no reddening? be honest, now.

many other examples of importuna here on MO …
By: Debbie Viess (amanitarita)

that look like this obsie … imperfect laddering, same coloration.
here’s a few: 516847, 316370, 413092, 323540, 328170.

the evidence of my eyes leans this ID more strongly to importuna than rufobrunnea. not a “perfect” match to either, wouldn’t you say?
