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


Thanks in advance

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?

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this hard to find paper will be very useful to many of us, even though the nomenclature is a bit outdated.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

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?

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.

Christian

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

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.

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.
