Calonectria (?) on wood
Martin Bemmann, 05-07-2011 11:54
Martin BemmannBonjour,

last weekend I found these minute ascocarps (0.25 mm dm.) on an indet. piece of wood stained by Chlorociboria (some immature apothecia were present).
The spores are fusiform without clear septa and filled with small oildrops.
Is a determination possible without culture?

Best regards

Martin

Hi Martin

did you consider Tubeufia cerea? I suspect if you add Melzer or CB you will clearly see the septa.

Yes indeed Zotto! This fits perfect!

Thanks,

Hi Martin and Zotto,
   I think to have collected the same ascomycete, please see the attached photoes!

Re : Calonectria (?) on wood
Ciao Erio,

most probably the same. I didn't find the time to check the septa, yet. Hope to do this at the weekend (in case something is left of the specimens....)

Cheers

Ciao Martin, Hi Zotto,

 ok Martin.

  Erio


PS: in the macrophoto the ascomycete on the left is an Orbilia.

Re : Calonectria (?) on wood
Hyalorbilia I presume. There were also some on my collection but they were vanished the next day... :-(

Cheers,

Martin

Re : Calonectria (?) on wood
And here (as Zotto had predicted) the septa of the spores visible in CB.

Cheers

Hi Martin,
   is it possible to locate the Hyalorbilia with these microphotoes?

Re : Calonectria (?) on wood
Hi Erio

Clearly an Orbilia (because of bifurcate  ascus base and capitate paraphyses), and obviously O. eucalypti (= O. alnea, = O. coccinella s. auct.)
