Interesting Perithecia from leaves of Ledum palustre
Nina Filippova, 20-06-2014 13:49
Hello. This species was overmature, lacking any spore-producing structures inside. But spores (or conidia?) were abundant, and their shape and perithecia form quite characteristic. So i hope its position could be defined from these features.

Coordinates: N60,891352° E68,690042°, 16.06.2014.

Perithecia on lower side of the leaf, scattered, submerged under epidermis with protruding neck, up to 400 mk high, perithecium about 150 mk in diameter, neck about 30-40 mk broad, with collar up to 100 mk.

Outer peridium from brown angular cells, covered with outgrowing hyphoid brown setae up to 200 mk long, 7 mk broad at base; neck covered by parralel brown hyphae 3-4 mk broad, in upper part of the neck these hyphae create rosette; spores cubical, about 6.7 x 6.3 mk, with thin wall on two opposite sides.

Re : Interesting Perithecia from leaves of Ledum palustre
This is a species of Scopinella - possibly S. solani but it's a long time since I worked on them. They are ascospores rather than conidia - the asci deliquesce at an early stage.

Re : Interesting Perithecia from leaves of Ledum palustre
Thank you, Paul. I will look later in literature for exact identification.

Nina.

Hi Nina,

This may be S. barbata Lév.

My notes say:
"Growing on decaying oak leaves in Europe and Algeria.  Asci 8-spored.  Ostiolar hyphae extending well beyond the fused portion of the neck and forming a basket-like arrangement holding spores. Lateral hairs of the ascomata not spine-like and fused in groups of only 2 or 3.  Spores more than 5-6um long"

It may not be restricted to oak leaves; there are probably not enough reports of this species in the literature to be sure about substrate-specificity.
