Dothideomycete with appendaged septate spores possibly parasitic on Bacidia rubella
Björn Nordén, 08-10-2014 14:25

Hi!


 


I found this small setose fellow on a piece of bark from mid Norway. The pseudothecia are 0,25-0,4 mm in diameter, setae smooth light brown in the microscope 25-40 x 2,5 mym, asci clearly fissitunicate, pseudoparaphyses net-like, ascospores 3(-4)-septate, light-brown but outermost cell hyaline and with appendage, both the hyaline cell and the appendage falling off, whole spore measuring 24-30 x 9-10 mym, spores 4-8 per ascus.


 


Greatful for any ideas!


Björn

Lieber Björn, Das muss eine Teleomorüphe von Truncatella oder Pestalotiopsis sein, womio ich im einzelnen aber auch nicht bewandert bin.  Herzliche Grüße  Walter

Re : Dothideomycete with appendaged septate spores possibly parasitic on Bacidia rubella
Dear Björn.
Mayby it is some species from genus Rebentischia  (R. unicaudata).


With best regards,

Martin.

Hi Björn,


I don't think that this Rebentischia is associated with the lichen.


A vertical section could show it, if necessary.


I see another fungus on your photo, it's setose. What about it ? Perhaps  a lichenicolous fungus there.
