on Tubaria furfuracea
John Plischke, 13-01-2013 03:46
John PlischkeHello,


I found some Tubaria furfuracea today and thought they may have Nectriopsis tubariicola on them.  I got a new microscope Leica DM1000 with a Leica camera and thought it would be a great time to try it.  The software that is supposed to measure the spores will no work so I need to order a reticule so for now I can not provide any measurements.  The description I have for    Nectriopsis tubariicola says ascospores 12-16 X 3-4um, 2 celled, fusiform.  So what else could this be?  Photos taken with melzers. 


Thank you,
John

Re : on Tubaria furfuracea
Hello John,
I think that it is cladobotryum-like or  verticillium-like, they are anamorphic states of Hypomyces. Unfortunately without micro it is very difficult to say. Could you please to send a photo of conidiophores and conidia from thinner preparation in water?

Regards,
Christian

Re : on Tubaria furfuracea
Hello Christian,


They do look Verticillium like, I took a few more photos in water and borrowed a old microscope to take some measurements.  The ones in the first photo of this group are about 7um long. 


Thank you,

John

Re : on Tubaria furfuracea
Hi John,
it could be the anamorphic state of N. tubariicola

Have nice day,
Christian

Re : on Tubaria furfuracea
and the field aspect certainly looks right as well. Keep watching the place. You may be lucky to encounter the teleomorph as well. Esp. the anamorphic state is common in Demark

cheers

Re : on Tubaria furfuracea
Thank you Christian and Thomas.  I will keep checking the spot to see if the teleomorph appears.

Thank you,
John
