Unknown disco from Scotland
Derek Schafer, 17-05-2022 15:28
Kerry Robinson found this stalkless brown discomycete with white hairs in beech leaf litter on possibly beech (at least deciduous) fallen stick. The hairs were long, tapering and thick-walled; 50-70 microns long x 3-4 (base) to 1-1.5 (apex) moderately granular towards the apex. Spores 5-6.2 x 1.3-1.7 average 5.7 x1.5 microns. Any ideas what it might be?

Dear Derek

this is a member of the Hyphodiscus stereicola complex which is not a Hyphodiscus, but a Cordieritidacee without a known generic name. The complex is quite difficult, we have not yet a clue to distinguish among the species, especially because some of the sequenced specimens remained undocumented, a frequent mistake.

I would be pleased to add the collection data to this sample. Fagus is easily recognoized when looking for the pores and radial rays already with a handlens. A photo of a cross break could help.

Re : Unknown disco from Scotland
Thanks Ingo,

We had considered Eriopezia caesia but the hairs seemed to rule it out.

Re : Unknown disco from Scotland
Eriopezia has a brown globulosa.

Ah: did you test the iodine reaction? The asci should be negative as all Cordieritidaceae.

Re : Unknown disco from Scotland
Thanks Zotto,

Fascinating! Hope the names get sorted out before too long, it is a very distinctive looking species. We will try to get a sequence on it. Please do use our data if it is of any help.

Best

Derek

Re : Unknown disco from Scotland
Thanks! Tell me please if you find out something about the substrate.

We have a lot of collections and the issue is quite old, but too many species are so difficult that a species concept is almost impossible to obtain.

Re : Unknown disco from Scotland
Thanks zotto. Kerry can send you the material if you would like to look at it. I have a few fruitbodies dissected from the wood for an ITS sequence. We have another 'Unknown disco from Scotland' and will post details just now

Re : Unknown disco from Scotland
Hi Derek

it is great that you want to obtain a sequence. I will put the pics in one of my viridula folders, waiting for results. There is little help in studying them personally, the features are so similar and I have no clue as yet.
