Xylaria
hannie wijers, 20-02-2016 17:21
Good afternoon.
Ik like some help from someone.

In the Bush (tropical conditions) of a zoo I found these Xylaria. They grew at wood and had a decent length. I took some material and at home I did it under the microscope. I was expecting brown spores and was surprised to find clear spores. This appears to be a anamorph? The sizes of the Konidiensporen between 4.5 to 8 x 1.5 - 4 microns.
Has anyone an idea for me?

Re : Xylaria
Hi Hannie,
what you observed under the microscope is indeed conidia, not ascospores. Xylaria spp. can rarely be identified at this conidial stage, especially tropical ones. You can just try to incubate the piece of wood in "tropical" conditions.
Good luck!

Re : Xylaria
Hello, 

I'm very curious and have no peace with this species. I got through a forum of Marijke Nauta whether it might not be a Phaeoisaria? I looked at Ellis and Ellis (microfungi on land plants p 60) and think this may be perhaps Phaeoisaria clamatidis?

Any suggestion?

Re : Xylaria
Hi Hannie,
Phaeoisaria is rarely over 1 mm high and can hardly be confused with a Xylaria. You did not mention the size of your fungus but I guess it is several cm high.
Moreover, such conidia only are usually not suggestive of a hyphomycee genus, you have to study carefully the conidiogenous structure which is basic to the classification of hyphomycetes.
Cheers,
Jacques
