Identifying Ascocoryne sarcoides from the anamorph
B Shelbourne, 02-08-2024 18:09
B ShelbourneIs it possible to identify Ascocoryne sarcoides in the UK (Europe?) from the anamorph without microscopic examination?

I have read that microscopy is better to distinguish the apothecia from A. cylinchnium. Is this the only similar species to consider, and is the brain-like anamorph only formed by A. sarcoides?


I include some photos from southern England, last year (20/11/2023), showing both morphs together on the fallen trunk of an unindentified angiosperm, possibly Betula, in mixed deciduous woodland.


Thanks in advance.

Hi Ben

yes, this anamorph can hardly be anything else than A. sarcoides. The apothecia probably belong to it, but that requires the microscope.

Our work on the genus revealed distinctly more species than three in Europe as previously thought. But the anamorphs are always small and mostly roundish in outline.

Hi Zotto,

Thank you for answering, it seems the third traditional species you referred to must be A. albida (solitaria).


I do have another collection from the same day, a few minutes walk up a nearby stream. This was a solitary, small, purplish apothecium, on very damp and decayed wood that I suspect is Fraxinus excelsior.


I thought this may be an A. sp. too, although the habitat and habit seems a little different. I still have the dried apothecium but I haven't worked with dry material before and I guess it will be harder.

Re : Identifying Ascocoryne sarcoides from the anamorph
In dry state this will be very hard. I wanted to say that you need to compare the degree of yelly consistency. A. sarcoides apos are highly genatinous, A. albida also, but A. cylichnium has rather tough apos. You need to look e.g. for crystals in the medulla and for conidia formed on overmature spores.
