Lachnellula pulverulenta?
Steve Clements, 13-04-2017 21:13
Bonjour,
Nous avons trouvé une Lachnellula avec des cheveux jaunes et des granules de résine, un peu d'un couleur rouge-orange, sur les feuilles de Pinus sylvestris.
En lisant la clé par Baral, c'est un genre difficile!
Peut-être que c'est Lachnellula pulverulenta! Je le doute....

Hello,
We found this tiny Lachnellula, with yellow hairs with some orange-red resin granules, on dead Pinus sylvestris needles. Reading Hans Otto Baral's key to world Lachnellula makes you reaslise how difficult this genus is, and how few species are in the British guides. Elllis & Ellis decribe something similar to this as Dasyscyphus pulverulenta, but it's not at all common in the UK and Ireland.
The discs were up to 1 mm wide, almost sessile, very thickly covered in twisted pale yellow hairs, with resinaceous matter including some which was orange-red. (Some Myxomycete spores are also present). Spores were up to 7x2, which is a bit longer than in Elllis & Ellis. Paraphyses extended beyond the asci.
It's a nice disco anyway,
Cordialement,
Steve

Re : Lachnellula pulverulenta?
Indeed, and I still prefer to say Dasyscyphella pulverulenta for this species, although molecular data place it in Lachnellula. It has actually little in common with that genus.
