I will try to make more and better Fungi pictures in the future

the site is by no means exclusive to “scientific grade” contributions. your photos are as welcome here as any. you’re encouraged to document as much as you can when you can, but there are no specific criteria for what level of comprehensiveness is required. personally, the more I get to see of Neotropical fungi, the better, extensive note taking & photography or none.

short answer: keep uploading!

A note on my photos …

Sometimes I am doubtful about posting pictures to MO because I work with orchids and I go to the wild to work with orchids, and I find many mushrooms around. Once a time I decided to make pictures of them, and then I found MO and decided to share photos on this community, as well as Flickr and Facebook. Sometimes I use a very limited source of information on costarican fungi (http://www.inbio.ac.cr/papers/hongos/intro.htm), but of course I dont any serious work with them or with the pictures.

I am sorry to admit that at this time I am not doing science on my pictures. Said that I must ask you, is this community a place for my pictures, even when on my situations I can not even purpose a genus name? Ive learned a lot here but I dont want to fool around if this is a more technical website.

If it was about orchids and you were publishing ´anything´ without any expertise, I would probably get mad on you.

Thank you all for all discussions and support !!

“MO should encourage microscopy”
“MO membership should be able to vote for the removal of certain observations”
“Observations should use a plural, parallel voting system”
“MO should provide a page specifically tailored for going through unidentified observations”

Neat Idea

Maybe observations could be ranked or “rated” according to completeness, sort of how the pictures are scored, but in terms of completeness, like 5 stars for having it all (macro shots of the cap, gills, etc, habitat, and microscopy).

would be to discourage contributions to the site that don’t meet a particular set of criteria, which runs contrary to the all-inclusiveness that the developers are intent on fostering. The labels Mixed collection, Duplicate and Imageless alone were enough stir up a fuss for a few days until the dust settled and their practical application could be amply explained and demonstrated.

Your idea does have traction, make no mistake, though something like what you’ve suggested is more likely to be implemented through the use of positive reinforcement over all-caps condemnation. Essentially, observations meeting some predetermined base criteria will be rewarded in some way, either with more “Contributor” points or receiving some kind of special, exemplary status.

Obs that lack both a photograph and description of the spore bearing surface should be given the title “INCOMPLETE”.

argument comes with the territory. you propose, I disagree, you disagree with my disagreement, we come to a consensus or we don’t. tis the nature of public fora, friend.

rather than battle it out with votes… again… like two toddlers with action figures, why not take the opportunity to try and break down said votes and the limitations of the system which governs them? Major site fixes/features/enhancements have come about from less. I find that more interesting and more productive than artificially inflating one vote or deflating another, one observation after another.

Returning to the lonely photograph at hand, if this is a Lentinus (and it probably is), L. velutinus is the only conceivable possibility to my eye. Find me a single fuzzy-stiped, similarly proportioned, non-striate/-sulcate Lentinus with known Neotropical distribution outside of L. velutinus and I’ll eat my hat… again.

i’m not here to argue or get into philosophical discussions.
imo, there is enough evidence to support Lentinus, but not L. velutinus.
people can vote how they wish…

the one observation
By: Danny Newman (myxomop)
2012-09-28 22:00:20 CDT (-0400)

featured on the name page for a given taxon is that which has the highest cumulative confidence level supporting a given name proposal. since no one, including either of us, is in any hurry to assign 100% confidence to something we can’t even see the bottom of, that’s not a cause for concern here.

this brings up a couple of presently unavoidable chinks in the armor of the voting system as a whole, namely that only one proposal “wins” an observation. we can’t both agree that it’s an agaric, or a species of Lentinus, and have those debates be settled while we move onto the question of species. instead, every proposal is simultaneously contending for the title of big bold italicized title, and this can be problematic, as seen here.

i knew…

2012-09-28 21:54:25 CDT (-0400)

you were going to say that.
the most accurate id is the best id.
we cannot say for sure that it is indeed L. velutinus…
and i would certainly not want it to be one of the observations that exemplifies the species…
would you??

The voting system
By: Danny Newman (myxomop)

can be used one of two ways, either chosen at the discretion of each user.

1. to express one’s degree of confidence in a name proposal.

2. to sway consensus in a direction favorable to the whims of a given voter.

If it ‘Could Be’ Lentinus, and you concede that given the description of L. velutinus from Pegler’s monograph, it also ‘Could Be’ L. velutinus (although surely an older as opposed to younger one), why vote ‘Doubtful’ on one and ‘Could Be’ on the other?

i agree…
By: Richard and Danielle Kneal (bloodworm)
2012-09-28 21:34:26 CDT (-0400)

by the description you posted the other day and having found it…
that this could indeed be a young L. velutinus.
however, without seeing the gills, we can’t know for certain.
the “could be” Lentinus vote seems more “accurate” to me.

By: Danny Newman (myxomop)
2012-09-28 21:31:58 CDT (-0400)

why not L. velutinus?
