Avant de me coucher, je vous propose une récolte que je n'ai su nommer. Des discomycètes jaunes trouvés au sol sur herbe pouvant atteindre un petit centimètre, blanc sur le stipe (jusqu'à 8 mm) et la partie inférieure. Spores hyalines (à peine colorées) de 11-15 x 2 µm, asques I+.Je sais que cette description ne suffira probablement pas mais je suis fatigué et me tient à votre disposition pour d'éventuelles précisions.

Hi Alain
I would suggest to search in the direction of Lachnum pygmaeum. The sbstrate looks gramineous. Please have a look at the margin and exterior of the disc for about 30-40 x 3-4 µm large, straight warted hairs. Lachnum pygmaeum was often thought to be a Hymenoscyphus (or Helotium) because of its large size and comparatively short hairs.
