Diplodia taxi? = Cryptocline taxicola

Hello,

Found by Laurens van der Linde (May 2021, the Netherlands) on Taxus baccata "Repandens", on dead leaves still attached to the shrub.

Is this Diplodia taxi? I read that the conidiogenous cells should have collarettes in case of Cryptocline.


Conidia Me = 18.5 x 6.8 µm N = 10

Greetings, Riet

Re : Diplodia taxi?
Hello Riet

this reminded me of an earlier discussion - thanks for providing the link to that thread. My conviction that my fungus was Diplodia taxi was at a stage when I was unaware of the Cryptocline - although it is included (as a Gloeosporium) in vol. 2 of Grove's "British Stem and Leaf Fungi" - see http://www.cybertruffle.org.uk/cyberliber/01210/index.htm (page 226).

I have also come across https://core.ac.uk/download/pdf/235699268.pdf which perhaps you already know? Based on that and Marcus Yeo's useful comments on that earlier thread (especially the size of conidia and absence of any brown coloured ones) I am fairly sure that my fungus was Cryptocline - I must re-collect it.

It underlines a problem with the Internet: a search for images of Diplodia taxi brings up an image of my original find, and which I now think was mis-named. Many people trying to identify fungi unwisely "look for pictures on the web" as their main taxonomic tool, and any images there can assume a spurious accuracy - "onechte nauwkeurigheid".

I shall remove the image from that ASCOfrance thread, but it may stay on the web forever . . .?

Best wishes, Chris

Re : Diplodia taxi?
Hello Chris,
Thank you very much for page 226, the pdf and your information.
Because of the size of the conidia and the absence of any brown coloured ones Laurens's collection could also be Cryptocline taxicola.
Best wishes, Riet

Re : Diplodia taxi? = probably Cryptocline taxicola
Hello,

in a last year's collection of C. taxicola (from autochtonous population) I noticed spore sheaths, easily stainable with aqueous congo red. Usually they were wide and excentric, but sometimes they were tight and only a little bit loosened near the poles (bottom left photo). This might explain those "appendages" in the previous thread. I haven't noticed any sheath in Diplodia sp. on Fraxinus - are they lacking in D. taxi too?

Best wishes,
Viktorie

Re : Diplodia taxi? = probably Cryptocline taxicola
Got a mail from Laurens v.d. Linde. He had sent a mail to mr. R.K. Schumacher.
Mr. Schumacher: "......thank you for sharing your information.This is NOT a Diplodia-like. Only in a very young state of development the immature conidia can be hyaline and do have coarsely guttules. But the arrangement of the guttules is not the same as in Cryptocline. A good work name is Cryptocline taxicola ......."
