Unknown disco from Scotland

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?

Hi!

Compare with Eriopezia caesia.

Re : Unknown disco from Scotland

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.
