Hello :-)
Elsa Sousa, 02-03-2017 00:19
I found this asco on a herbaceous stem, it reminds me (macro) neobulgaria, but it is much smaller. Apothecia ~138 microns diam. up to 328 high.
Spores are too difficult to measure, I measure only 6 all in asci, 12 x 4 mic.
I'm not sure if some are overmature/dead? (asci empty with vb's)  and some imature, or all imature. Color pink, greyish around "apothecia". Gelatinous.

Any idea?

Thanks
Elsa

Re : Hello :-)

Hello Elsa,


I also think your fungus looks like Ombrophila (Neobulgaria) pura.


I do not think it is overmature. In the opposite, it seems to be unripe and young, and the small size should be because of this. O. pura-apothecia begin quite small before they ripen and grow large.


The ascus you show with the spores within look very unripe and premature.


Maybe I am wrong - but then somebody else will contradict.


Best regards from Lothar

Re : Hello :-)
Thank you Lothar, for your opinion.

If we consider it immature though, shoudn't the spore size be smaller?

Re : Hello :-)

Hi Elsa,


yes, you are right. The spores are too large and the form does not fit, too. I did not compare accurately before because: ...


Anyway, your collection is unripe to a high extent. You see this (for instance) in the asci not being translucent. You should have ripe asci with ripe, free spores to measure and to have a good base for determination.


Regards from Lothar


P.S. I just now see that you found it on a herbaceous stem. This also excludes pura but leaves a quite number of other (partly named, partly not) Ombrophila species.

Re : Hello :-)
Thanks again Lothar. I'm a beginner with this, so all is useful to learn. My intention is not to name this fungus because I know it's impossible.
But I surely would love to know what else could it (possibly) be.
Any brainstorm?

Regards,
Elsa

Re : Hello :-)

Hi Elsa,


impossible? - I don`t know.


I think it is an Ombrophila species because of the gelatinized excipulum and the spores with obvious guttules, together with the habitus and the lilaceous colour.


Ombrophila is not quite an easy genus - I have a number of good collections without proper name.


Best regards, Lothar

Elsa Sousa, 02-03-2017 15:20
Re : Hello :-)
Yeah, I think the same. I found a spore out of the asci, but I'm not sure if it belongs to this fungi, or a contamination.

I'll upload the image later when I get home.

Thank you very much.

Elsa

Here are the 2 images that could represent spores, but I'm not sure if it belongs to this fungus.
