[Unguiculariopsis parasitica] Asco on Eutypa sp. for ID

Yannick Mourgues, 21-10-2010 00:21

Hi everybody !

Here is an asco found on Eutypa sp. by a friend of mine. Lozère 16/10/2010.

May be it'is too old for ID but may be you'll have an idea ?

Ascomes <0,5mm diam. Grey to white.

Spores cylindrical 8-9x3-4 um with 2 guttules at each side with many very small ones all around.
Ascus IKI-, no croziers, 45-60x8 um
paraphyses curved at the end, 2-3um wide at the base and less then 1 um at the end.

Any idea ?

Re:Asco on Eutypa sp. for ID

Hi Yannick,
You mean the hairs are curved? This is a Unguiculariopsis species, probably U. parasitica which is known from Eutypa lata, if you have 10 Mb free in your postoffice you will get literature soon.
please upload some more micropictures.
Amitiés
Stip

Re:Asco on Eutypa sp. for ID

Thank's Stip.
I was just looking at Zoto DVD and found this genus Unguiculariopsis.
So, what I have seen are not paraphyses but hairs ???
I'm ready for your 10 MB litterature !
Which pictures would you like ?
Yannick

Stip Helleman, 21-10-2010 01:08

Re:Asco on Eutypa sp. for ID

Hi Yannick,
these are typical Unguiculariopsis hairs, it would interest me to see the living asci and spores.
Amitiés
the literature is gone already

Re:Asco on Eutypa sp. for ID

Re:Asco on Eutypa sp. for ID

Here is a picture of ascus. But it's a bad one and I can't make better.
If you are interested by this recolt, may be I can send it to you ?
Good night !

Hi Yannick and Stip,

Unguiculella eurotioides has such curved paraphyses.

Cheers,

Martin

Hi Yannick

The colour of the disc looks like Unguiculariosps, could you do a section or otherwise look for the excipulum (brown in Ungnuiculariopsis, hyaline in Unguiculella)?

Re:[Unguiculariopsis parasitica] Asco on Eutypa sp. for ID

Thank's a lot.
Zotto : Excipulum is brown here. I'll try to make photos this night of a section.
