Hallo Peter,
hast du ein Bild des Pilzes?

Hier die Beschreibung aus Corner:

"C. pullei Donk.
- 4cm. x 1,5-3 mm, simple, solitary or gregarious, cylindric, sometimes dilated upward, subacute or blunt, slightly longitudinally rugulose, dark brown, rufous, or blackish brown: stem indistinct, short, paler brown, finely cottony, base white: flesh greyish brown.
Among grass: Holland
Spores 4,7-6,7x4,3 µ, white, smooth, ovoid, mostly 1-guttate.
Basidia 20-36 x 5-6,5 µ: sterigmata 2 (? always, few basidia seen).
Hyphae 4,5-9 µ wide, -16 in the central tissue, thin-walled, no clamps seen.

The absence of clamps clearly indicates Clavaria, but the guttate spore suggests Clavulinopsis. The affinity of the species seems to be with C. atro-umbrina (narrower spores, more rugulose hymenium). Donk says it is related with C. greletii rather than C. tenacella, but it is not easy to appreciate the difference from this last , of which only the original de#####ion appears to be known."
