Hi Javier

this is a Hyalorbilia (t. prismatica, short unstalked asci), and I strongly suspect you have H. ulicicola, a quite common but still undescribed species. Did you see the droplets at both spore ends?

Did this grow on a branch lying on the ground? I would much like to note date and locality, can you tell me?

You cannot get sharper photos of the spores? I looked at your metadata: With Canon Powershot your images should get better. 1/4 sec. shutter speed is much too long, then you easily get trembling and unsharp images. 1/30 is minimum. I think the aperture is the reason: 6 is much too high, try to reduce it as much as possible, 3 or lower. Tell me if you succeed.

thanks
Zotto

I must apologze, I looked in the wrong image for the metadata. For your micro it is Nikon E4300, 1/16 and aperture 4,9, zoom 24 mm. Guy says that a more open aperture is not possible with this camera. So I do not know the reason for this poor quality. maybe it helps to use a lower zoom and full image resolution?

Zotto

Ok, prismatic = Hyalorbilia.
I thought H. ulicicola for your macro, but being different substrate (Ceratonia siliqua), plus smaller asci and spores ......... Spore image of the only preparation I did, was very poor. Try to get better ....
The sample is from Valencia. El Saler. Gola de Pujol. 12.02.2011 at branch remains very poor, almost rotten Ceratonia siliqua.
Today I had another discovery, I have to look.
Want samples?
Greetings
Javier

Your spore data are really a bit small. I have *(3–)4–5.5(–6) × (1.2–)1.4–1.7(–2) µm for 16 collections. Dead asci were 20–33 × 3.5–4.2 µm.

You need not send, first please try to see more spores and whether they contain 1-2 spore bodies at each end.

Zotto

He returned to watch another specimen, more mature, larger spores with guttae poles. It seems reasonable to think of H. ulicicola.
The funny thing is that I have seen another this morning in the same substrate, this does seem orbilia, then send alert.
Greetings
Javier

As we say in my country: More lost than "Carracuca"
Difficult to study
Individuals less than 1 mm.

Asci cylindrical, many with forked base, biseriate, up 44 x 5 microns. Irregular cylindrical-fusiform ascospores with several guttae (no more than 4-5) scattered, 5-6 x 2-2.5 microns. Very capitate paraphyses up to 5 microns, with very thin stem.
Ectal Excípulum angularis textura, but some cells showing globose and subglobose
Any orbilia approximately?
Best regards

Are you sure with the spores? I see only inside the asci, and they look strongly curved, semicircular, surely smaller than you say. I think this is O. delicatula, or, as we now say, O. leucostigma.

Would be the first record on Ceratonia, but needs to see free spores which should be warted.

Zotto

I searched spores that are somewhat visible photo, although I would see my micro poorly. The measures and form are correct and if they have warts
Another poor image of spores

I can hardly believe. In the asci I see croissants!

These spores here look lke coccinella s.auct. = eucalypti.

Zotto

I do not see "croissants" in the asci and I have clear that this is O. eucalypti

o.k., your drawing is clear. But for the photo look here. It might be a deception but I was versy sure.
Zotto

When there is bad microscope, the image is often poor and misleading.
The approach would be O. eucalypti?
Thanks

yes, this one looks like. If you would find conidia around, this would much help. There are some more rare species with deviating conidia, usually forked ones (like a V or U).

Zotto

I have no experience with orbilias excessive, but it is rather difficult to accept that both images above, are the same species, in addition to the red (O. eucalypti) is quite larger.
That is the question .............

Javier

Dear Javier

This photo with red colour looks for me a but false, I cannot help. But I assume you clearly saw a colour difference. Well, colours may be important but must not. If you do not find any microscopical difference I would say that this is the same. But often different Orbilia species grow together.

Zotto

We will have to do a better micro. Promise information.
Thank permanent
