Re : Arnium Cervinum?

Là aussi , espèce proche d'Arnium inaequilaterale et d'Arnium subtile; verifie la présence et le type de poils, ainsi que l'appareil apical.

Michel.

Re : Arnium Cervinum?

I will have a look if I can find photo's of fruitbodies with hairs.

Re : Arnium Cervinum?

Hello Joop,

maybe that this is Arnium cervinum. I believe to see some stiff hairs on the neck.
The gelatinous caudae are typically excentrically attached.
This species is not rare in Saxony (Germany). So I had 17 findings on dung of deer/roedeer, but also one time on horse dung.

Arnium subtile has symmetrically placed appendages and in Arnium inaequilaterale the appendages are also more symmetrically than excentrically attached and there are no hairs of course.

Re : Arnium Cervinum?

Hallo Norbert,

I checked the photo closer and it has indeed hairs in the neck area especially on top of the neck. Also the young spores did match.

Asci measuring 206.34-221.66x31.87-34.25 um with long stalks.

Spores: 35.02-36.75x18.95-19.44 um

Caudae: 56.64-59.72x5.93-6.15 um

Re : Arnium Cervinum?

Yesterday I found some new species and I made some photo's of the neck and messured the hairs.

Hairs are septated with a round top: 75.32-89.71x2.89-3.55 um. Thickwalled 0.81 um thick.

Can you confirm that this is A. Cervinum?

Joop van der Lee, 11-05-2013 15:22

Re : Arnium Cervinum?

Three more photo's of this Arnium found today.

Joop van der Lee, 13-05-2013 17:33

Re : Arnium Cervinum?

Hello Michel,

The photos I added do they satisfy your question about the type of the hairs?

hannie wijers, 14-05-2013 19:47

Re : Arnium Cervinum?

Are picture 10 and 11 the same? The type pf hairs look different to me.

Hannie

Joop van der Lee, 14-05-2013 21:32

Re : Arnium Cervinum?

They are the same Hannie

Norbert Heine, 16-05-2013 19:28

Re : Arnium Cervinum?

Nice new photos, Joop!
One can see the stiff hairs on the necks. But you show no mature spores!
Thatswhy I only think that it's Arnium cervinum, but I'm not sure at least!
The mature spores of my gatherings were mostly 37-43 x 18-22 µm.
Sorry, that I can't help you. To be sure, it needs more features.

Norbert

Re : Arnium Cervinum?

Hello Norbert,

I have found one with mature spores, messuring 34.51-39.84x19.07-21.96 um.

Hairs: width: 4,98 um, with a wall of 0.96 um
