Eutypella question
Chris Yeates, 23-12-2014 20:05
Chris YeatesBonsoir tous
firstly may I apologise for moving Zotto from the top of the Forum (where he certainly belongs ;-) ). Secondly I am fairly sure that I have the genus correct with this fungus - with its clustered perithecia, "Phillips screwdriver" ostioles and spore characters. I then spent a long time with Rappaz, brushing up my schoolboy French, and have come to Eutypella scoparia. My reservations were that this doesn't look to me like what I previously have understood as "Peroneutypa heteracantha", but I take on board Alain's comments here: http://www.ascofrance.com/search_recolte/2041 also Rappaz's comments about the variability of this taxon.

This collection is on a fallen Betula twig. Exidia nucleata and Stomiopeltis betulae - the latter of which can be seen in some of these images - were also present. As can be seen the apical apparatus is IKI+ (arrowed); ascospores measure 5.2-6.3 x 1.3-1.6µm.

Comments as ever would be very welcome.

Cordialement
Chris

Re : Eutypella question
Hi Chris,
the current concpt of E. scoparia is very wide and your collection most likely fits in it. To put your mind at ease, the world of Diatrypaceae is something very difficult to enter, even for people who read French.
Greetings,
Jacques
