Hello, bonjour.Here is the paper I'm searching for

brownish Microglossum from Portugal
Lothar Krieglsteiner, 12-01-2024 12:31
Lothar Krieglsteiner... collected already 2014, 16.12. Alentejo, in a small canyon between Quercus suber-"savanna", under bushes like Arbutus unedo and Rubus fruticosus s.l., together with another Microglossum (bluish-green, then detemined as "nudipes" but today to be re-examined, ... other topic) and Clavaria-, Clavulinopsis- and Hygrocybe-species. 
In 2014, I had only a bad equipment with me, so please forgive me the bad pictures (first ones, without Kongo, in H2O). I re-examined it today - shown by the further fotos in Kongo-NH3.

Living spores contained mostly 4 large guttules, I only took few measures (picture 5). Dead spores are with homogenous content and measure about 11-12(12,5)/3,7-4,3(5,5) µm - living spores were a littler bit larger as it seems.
Paraphyses are filiform to somewhat clavate at the top, branching and anastomosing.
Asci are IKI-euamyloid and after some time of searching I think there are croziers at the base (last fotos).

I do not find an European species of Microglossum with such a fresh colour (the ascomata were fully fresh and not disturbed at all). There is a species with name M. fumosum but I do not find a lot information about it.

Who can help with identification?

Yours, Lothar

Hi Lothar,
I assume you have tested M. rufescens? Came out top on the Identikit scale based on your description. Also details of this species at Paul Cannon's site at:
https://fungi.myspecies.info/all-fungi/microglossum-rufescens

No experinece with these just an observation.

Re : brownish Microglossum from Portugal
Hello Tony,
thanks for your proposal. But my specimen was not reddish but only yellowish-brownihs-grey. I am not very sure what must be determined rufescens now (thanks for the link). In my diploma-work I described specimens then determined as fuscorubens and cf. rufescens. Both were different in color to my Portuguese find.
Anyway - it will remain Microglossum spec. as I fear, for the moment.
Maybe I should once give it for sequencing.
Yours, Lothar
