Re:Other winter Orbilias
I can see at least 3 or 4, actually, Marja. ;)

(with no other characteristics, it will probbaly be difficult to give a name)
Marja Pennanen, 04-02-2011 13:03
Re:Other winter Orbilias
I haven't studied the pink one yet, think it is O. rubella.

The yellower I studied and I suppose it's O. auricolor.

Sorry, but I got no better photo of the spores, which are about 10-12x1 and slightly bent.

Re:Other winter Orbilias
The asci are about 40-60x3-4, IKI-.
The paraphyses are swollen at tips to 3-5 micrometers and yellow and maybe incrusted is the word for their appearance.

The substrate is bark of Salix, which was fallen on the snow. It seemed to have its origins above 2 meters hight.

Re:Other winter Orbilias
Hi Marja

yeah, the yellow one is O. xanthoguttulata. That likes to occur with O. phragmotricha (= rubella s.auct.).

Also Karelia and Prunus padus?

Re:Other winter Orbilias
Hi Zotto,

thank you :)
The paraphyse tips are not perfectly lined.
O. xanthoguttulata has not been determined in Finland at least before year 2001, must be a new species.

This was bark of a dead Salix caprea still standing and I can almoust see the trunk from my window (meaning Raivionmäki).

Smiling even more: Marja

Re:Other winter Orbilias
Thanks. Yes. it is new, but it is not new to Finland :-)

Karsten (1870: 248, 1871: 102, p.p.) as O. rubella

(Karsten mixed this and rubella, at last I found only xantho in one of his specimens, whereas the others of him were phragmotricha)

Re:Other winter Orbilias
Dear Marja

try to gather your collection data. Could you please give me the date of the present find? Did you check the rose orbilia?

Re:Other winter Orbilias
Hi,

ooh yes. It's what I used to think O. rubella and may have some problems to remember any other way ;)
I found no conidias near O x.

Lat: 62° 43.588' lon: 29° 0.085', if I took the righ ones...
Collected 30.1, 2011.

Thank you once again.
Maybe I'll bring other Orbilias here, if/when I find them during our winter, which will still last some months.

Re:Other winter Orbilias
Hi,

oh yes, it was propably the one I used to think as O. rubella. The specimen is already at Joensuu.
I found no conidias near O x.
Collected 30.1 2011, Raivionmäki, Outokumpu,lat: 62° 43.588 lon: 29° 0.085, if I picked the right coordinates .

Than you once again: Marja

Re:Other winter Orbilias
I can presently not check coordinates because GE does not start.

Did you see the hairs of phragmotricha, because t could be rubella as well.

Re:Other winter Orbilias
Hi,

no I didn't. Just checked a couple of spores and asci. I've got too many specimens to check and too little time. So I believed in you determination and did nothing else.
As a matter of fact I thought, that O p. is a new synonym of O r . Should know that tricha means hairs, but my latin still needs a lot more work.

No harm has still happened, I just tell the person I delivered the specimen to look better ;)

By the way I did take some photos ;)

Re:Other winter Orbilias
Bingo, that is enough! phragmotricha means "with sepate hairs" ( a name invented by Evi). The true rubella has also septate hairs, but shorter and with a short to very long glassy process on each.
