Orbiliaceae on Salix confirmation
Nick Aplin, 05-01-2016 01:45
Salut à tous,

I wonder whether anyone could help me with this +/- xerotolerant species I found on dead, still attached Salix branches on 1/1/15....


51.129347°N -0.15229797°W, 70 metres above sea level


Ascospores 6.8-8 x 2.6-2.9 µm


The Asci were without truncate apices, and each had a big crozier at the bottom so I started looking at the genus Hyalorbilia. I eventually found H.fusispora which seems to fit well, but I note there are probably similar species which I haven't considered.
Can anyone please confirm?


Thanks in advance for your help.


Amitiés,
Nick

Re : Orbiliaceae on Salix confirmation
Hi Nick

yes, this is clearly H. fusispora. First record for GB. What you can do is to look for the margin (in top view, or in median section): H. fusspora has rather narrow marginal cells (3-5 µm) while subfusispora has wide cells. (5-10 µm).

Wer the branches corticated, and the apos growing on bark?

Did you give a herbarium number?

Re : Orbiliaceae on Salix confirmation
Hi Zotto,

Yes, the apothecia were on bark

The marginal cells are never wider than 5 µm so OK for H.fusispora....

The herbarium number is N.A 333

Thanks for the confirmation,
Nick

Update: I just noticed an error - The collection date is supposed to be 1/1/16

I also suppose the year is 2016 :-) I made it correctly in my text but wrote 2015 in my database....
