Björn WergenHi friends,

I have a collection of a dubious pyrenomycete with very short stalked to sessile asci and strongly allantoid spores ("C-spores", like those of Calosphaeria dryina), but with a macroscopical appearance of a Valsa (10-15 very small perithecia of 0,2-0,3mm in a pustulate stroma, which is white inside and blackish outside). There is a rudimental black line between the stroma and the host (Cedrus!, lying on the ground).

Any ideas? The asci are only 25-30x5-6µm, which is very "freaky" in combination with the strong allantoid spores...

Best wishes,
björn
