Phacidium-like Fruit Bodies with Valsa-like Spores on Bark of Salix

Peter Thompson, 31-05-2013 12:07

Hello Everyone,

I recently found fruit bodies, each with an individual blackish stroma, peppering the bark of a dead twig of Salix.

The perithecia were flattened and located under the bark rather than in the dead wood.

I have attached images of the microscopy and the fruit bodies. The spores resemble those of valsoid ascomycetes, but the fruit bodies are individually immersed.

I wonder if anyone has encountered these before, and may know their genus and species.

Thank You,
With Best Wishes,
Peter.
