spores 13-14 x 5-6 ?m

asco

I think that _Microglosum nudipes_ is another possibility, due to the coloration of the specimens.

Greetings in the round,
yes, that' s probable M. nudipes. M. olivaceum have greater spores (20-25 µm long) too. Following two pictures.
Peter.

Thank you. How many species with green color there are ?

Hi everybody,
I had the same doubt between nudipes and olivaceum for this collection made a few weeks ago. I did not know this spore size difference between the 2 species. Is there a recent key of these green tinge Micoglossum ?

Regards,
Daniel

It seems to me that the dimension of the spores of M. olivaceum referred by Peter Püwert are a bit exaggerated; Those I know are (retained from Errotari 10, 2013, by Plácido Iglesias and Sabino Arauzo on the new species M. cyanobasis):
(14) 15,5 – 18 (20) x (4,7) 5 – 6 um
which are close to those of M. nudipes (otained from "Setas del Pirineo aragonés" 1. Micobotánica-Jaén 5(3), by Miguel Ángel Ribes Ripoll):
(11.6) 13.8 - 14.8 (17) x (3.1) 4.2 - 4.6 (5.7) um
Also the asci have similar dimensions. The distinction of these two species is made especially on the basis of the coloration of specimens.
On the question put by Vasileios Kaounas, on which species of Microglossum have green color: besides M. nudipes, which usually have a mixture of blue and green colour with variable hues, there is M. viride, this one with rugose stem.

Greetings in the round,
Spores up to 20 µm, 25 µm was an exception.
New is, Microglossum viride in the old sense are now two species.
Lit.:  KUCERA et al. (2014): Re-evaluation of the morphological variability of Microglossum viride and M. griseoviride sp. nov. Mycologia 106(2): 282-290.
Macroscopic difference are the color and the ecology, the microscopical character is not yet clear in the moment, any collages, unfortunately in german, for the two species I add.

Both article I have in PDF.

Yo pienso que es Microglossum nudipes.

Plácido

Can I get  a copy of the 2 PDFs

 At Great Smokey Mountain National Park in North Carolina last year I found one that I was calling Microglossum olivaceum but I very well be wrong.  I would like to learn a little more about these species.

 

Thank you,

John 

Here is Moingeon S. & JM - MM80-81.
Really difficult to separate nudipes from olivaceum !
M. viride and griseoviride have no croziers, so it's easier.

Best regards,
Daniel

Daniel,

Thank you,

John

 

In my experience your collection fits seamlessly into the variability of M.nudipes. You  asked for green species, I Adjunct other green collections, they around M.olivaceum and M.rufescens.

Según el estudio de Filogenia molecular del género realizada en Plácido Iglesias & Sabino Arauzo, Microglossum cyanobasis, Errotari 10 (2013):

"Las especies M. olivaceum y M. rufescens aparecen estrechamente
emparentadas (Grelet describió M. rufescens como una variedad
de M. olivaceum) aunque bien diferenciadas genéticamente por
lo que parece correcto su status independiente.
La única rama que no aparece totalmente resuelta es la que
agrupa las especies M. fuscorubens y M. nudipes, quedando en el
aire la posibilidad de que la segunda (descrita más tardíamente)
sea una forma o variedad cromática de la primera"

M. olivaceum está más próxima a M. rufescens que a M. nudipes.

Thanks Jean Paul,
I think M.nudipes and M.olivaceum are not the same species. I've been observating from 10 years ago and I haven´t see intermediate specimens. I also have not seen the color changes describing by Imai. M.nudipes is common in my area although this year is scarce and so far I've only seen three populations this season. M.olivaceum is less abundant in my area but I've been following 10 years too, and M.fuscorubens cf. is scarce but this year is relatively abundant and it has grown 4 or 5 years of last ten. There are years that any species not grow and the others grows abundant. In my experience M.nudipes is usually emerald green and occasionally with brown areas (such as Vasileios ones). I think that M.olivaceum has a variety of olive green and brown colors and have color changes throughout life, the stipe usually has very light colors. M.fuscorubens cf. in my observations has usually all reddish brown bodies.
I sent some exicattas to Viktor Kucera, and also to Placido Iglesias. We will wait to see what results get Viktor. It's a good new.
In the lots of hundreds of specimens of Microglossum observed in recent years, I've only found these specimens with mixed colors that create doubts. Attached a picture.
Thanks a lot for your participation.
Regards
Jorge

what about this one collected this year, the ascus a short like M olivaceum, but i am not sure if the green stalk is typical for this specie or it is just because the specie is so variable? the paraphyse where also not inflated.

Hola Jonathan, eso parece otra cosa, sería interesante un estudio más profundo o secuenciarlo.

unfortunatly i can't write in spanish, but i can say that i do not have the specimen anymore.

That I don't know that . It's seems interesting
Greetings
Jorge

then it might get me to regret the fact i didn't conserved it.

However anyone have any information about the provisory name Microglossum cyanobasis?

Yours are not Microglossum cyanobasis. I order you information to your mail.

I attach two chromatics forms of M.nudipes, collected last Saturday.  I hope that in the next future someone will sequence the two forms. I don't know which of the two forms was sequenced by Iglesias&Arauzo.
