Capronia porothelia?
Bernard Declercq, 09-01-2020 16:04
Bernard DeclercqHi,

Collected on Xylodon nespori on decaying wood of Pinus: Ascomata semi-immersed in the fungus, globose, 100-120 µm diam., black, setose. Asci 8-spored, e.g. 52x8 µm. Ascospores fusiform, (9)10-13(14)x3-4 µm, 3-septate, smooth, pale greyish brown. Hairs acute, 15-65x4.5-5 µm, with swollen base, thick-walled with narrow lumen, aseptate, dark brown. Peridium surface with pale brown textura angularis.

Your help is welcome.

Best regards,

Bernard

Re : Capronia porothelia?
Hi Bernard

you know that some Capronia species react hemiamyloid (Lugol) with their interascal gel? This might be useful for identification.

Re : Capronia porothelia?
Hi Zotto,

Yes, you mentioned this before on this forum. Where can I find any specific literature about this reaction within Capronia?

I am not sure if it is published...

Re : Capronia porothelia?
Hi, Bernard,

to me, Capronia porothelia is a common species on the hymenophor of old basidiomata of Laxitextum bicolor, where it usually grows mostly immersed and does not produce well-developed setae. I do not recognize this species here. A similar species, also growing on basidiomycetes, is C. spinifera, which could be a consideration. Another option would be that this is something around the very common C. pilosella and that the connection to the basidiomycete is just by chance. A tricky one, as is often the case with this genus...

Best wishes,
Gernot

Re : Capronia porothelia?
If anyone wants to look in my old and bad key, here it is. It shows where we observed amyloid hymenial gel and where inamyloid. It was either pure red (rr) or negative, never rb.

I also see that gernot made a key.
