Hairy asco
Malcolm Greaves, 04-02-2016 18:44
Malcolm GreavesCan someone suggest where to look for this small (max .45mm) white hairy asco found under peeling bark of probably an alnus.
The pointed septate hairs tended to be clumped together.
At first the all the spores I found were unusual (for me) in that they were septate with a rounded apex at one end and a pointed one at the other. With further investigation it looks as though these spores may be from elsewhere as the spores from the ascii were more bean shaped and non-septate. Most were 6-8 long (up to 12 for the septate ones)
Thanks
Mal

Re : Hairy asco

Hi Malcolm,


I cannot say much about your septate spores - but the rest could perhaps fit to Olla transiens - although your spores are a bit small. I see glassy tips at the hairs - so it should be a Olla.


Regards from Lothar

Re : Hairy asco
I agree, and Protounguicularia would be an alternative genus. The septate spores look more like conidia of a different fungus.

Thanks
There are certainly "glassy" tips to the hairs.
Have you a description of the members of this group?
Thanks
