Re : En tela de algodón
Hi Joseba,

this seems to be Orbilia flavideroseola (current name?) already reported from weathered cotton. Zotto will surely comment on this.

Regards

Martin

Re : En tela de algodón
O flavidorosella and O. carpoboloides are very similar, differences are in spore size.

O flavidorosella *(6.8–)7.3–10(–11.3) × (1.5–)1.7–2(–2.2) µm

O. carpoboloides *(7.7–)8.5–14(–17) × (2–)2.2–2.8(–3.5) µm

So it should be the latter.

Hey, great, I founded it some days ago at Portugal on Salix bark. O. carpoboloides too.

Thanks.

Ah, both Galicia and Portugal are empty on my distribution map. Would be pleased to get the collection data. Miguel-Angel, are your spores also long and narrow like those?

I would be pleased to hear from where your samples come.

Re : En tela de algodón
Hi Zotto

My spores are 16x2,2 microns. Perhaps tomorrow I could send more accuracy measurements. 

Portugal, Sabugal, Quercus pyrenaica forest with Salix, Castanea sativa and more, on Salix bark with another orange-red Orbilia not studied yet, 40°21'18.4"N, 7°02'01.9"W, 925 m., leg. Miguel Á. Ribes.

Thanks a lot.

Re : En tela de algodón
Thanks Miguel-Angel! So you had very long and narrow spores as well. Do you have any images? Of course the apothecia were hairy?

And thanks Joseba!

Hi Zotto

Tomorrow I will send you some pictures too.

Hi Zotto

Here are some measurements and pictures:

Spores (1000x, H2O, live)
(13,8) 14 - 18,3 (19,1) × (2) 2,2 - 2,5 (2,8) µm
Q = (4,9) 6,1 - 7,9 (8,4) ; N = 45
Me = 16,2 × 2,3 µm ; Qe = 7


Asci (1000x, H2O, live + died)
(79,7) 80,2 - 104,7 (118,9) × (4,9) 5 - 6,1 (6,6) µm
N = 17; Me = 93,1 × 5,7 µm


Conidiospores?? (1000x, H2O, live)
23,1 - 28,46 (28,5) × (18,5) 18,53 - 20 µm
N = 5; Me = 24,5 × 19,6 µm


Asci have the first fourth spores not inverted and the second fourth spores inverted.

I saw "in situ", at Portugal, a sample plenty of "conidiospores??", but I hadn't my camera. Days later, at home, I have only find some of them.

Re : En tela de algodón
Boah, such long and narrow spores! This supports a suspicion that carpoboloides is heterogeneous. But a sharp line to short+wide-spored samples is very difficult to draw.

The conidia should belong to Hyalorbilia orbiliicola (a species very similar to H. erythrostigma) growing on Orbilia apos, often also with their small apothecia.

A sequence could clarify whether the long-spored variants merit distinction, given that the parasitic Hyalorbilia does not disturb the extract.

The two identical sequences that we have are short+wide-spored:

Netherlands: *9.5–11.7(–13) × 2.7–3(–3.5) µm,

Luxembourg: *10–14 × 3–3.4(–3.8) µm.

Re : En tela de algodón
Miguel-Angel, I miss a date for your sample. The orange Orbilia might be O. aurantiorubra?
Miguel Ángel Ribes, 03-12-2019 22:03
Miguel Ãngel Ribes
Re : En tela de algodón
Ok, Zotto, I will try to sequenced it.

I have not study yet the other Orbilia, I will send it here.

Thanks.
