(Para)leptosphaeria praetermissa?
Howard Williams, 27-07-2017 13:40
Hello. In April 2017 I found this asco on a dead, cut bramble stem (Rubus fruticosus) at the edge of woodland. It keys out quite well to Leptosphaeria praetermissa in Ellis & Ellis and internet pictures also seem to correspond reasonably. In Britain at least it seems to be seldom recorded. Ellis & Ellis have it on Rubus idaeus, but there are records on R.fruticosus. Details as follow:


Fruitbodies black, ± circular, immersed with brown clypeus, breaking through surface; to 0.5mm.

Asci 75-96 x 12.5-13µm, irregularly biseriate.
Ascospores 17.5-21.25 x 6-7.5µm, 3-septate, ± elliptical, slightly constricted at septa, more so at the central septum; pale greyish-yellow in water.
Paraphyses not observed.


Substrate on dead cut bramble stem.
