Does anyone knows the actual taxonomic status of Nectria ellisii C. Booth?

Thanks in advance

Christian Lechat, 03-06-2015 20:46

Re : Nectria

Hi Enrique,
The name Nectria ellisii Booth is unchanged although it is not the genus Nectria.
According to Booth's description, it could be the genus Lasionectria.

Christian

Re : Nectria

Ok. Thanks a lot, Christian. Do you know if it has been formerly recobined in Lasionectria?

Christian Lechat, 03-06-2015 21:15

Re : Nectria

there is no new combination currently, I'm working to this!

Cheers,

Re : Nectria

OK. One more thing: Do you know where is a good description of?

Re : Nectria

thanks Chris,
this hard to find paper will be very useful to many of us, even though the nomenclature is a bit outdated.
Cheers,
Jacques

Re : Nectria

Maybe this fungus is 'Nectria' ellisii. My collection was made on Iris pseudacorus leaves on a damp place together with Nectriella dacrymycella.

The hairy yellow ascomata are 250-275 microns and the ascospores seem to be faintly striate.

What do you think?

Christian Lechat, 04-06-2015 20:11

Re : Nectria

Hi Enrique,
there are two possible genera: Lasionectria or Ijuhya. Hairs of Lasionectria arise from cells of the wall while the hairs of Ijuhya occur from the base of ascomata agglutinated to form teeth, arranged in a stellate fringe around upper margin of perithecia.
I attach two keys of these genera, maybe they will help you.

Regards,
Christian

Enrique Rubio, 04-06-2015 20:37

Re : Nectria

So I need to cut it. Well, I'll try it but I don't know if I'm to be able with so small ascomata.

Thanks Christian!

Re : Nectria

Hi Christian

Might you do a better idea with these pics?

Enrique Rubio, 09-06-2015 21:14

Re : Nectria

So my fungus could be a Lasionectria species, isn't?

Christian Lechat, 09-06-2015 21:49

Re : Nectria

Wow! Enrique, very nice, I think it is Ijuhya. This pecimen is very interesting.
It would be great if you could send me a part of your collection.

Christian

Enrique Rubio, 10-06-2015 12:22

Re : Nectria

Excuse me, Christian. I wanted to say Ijuhya...

Yes I'll send you my material. Remember that I think the ascospore are ver finely striate.
