disco on Abies cone
Malcolm Storey, 11-07-2018 13:11
Another disco from years ago. This one on Abies cone scales.

Ascospores: cylindric-clavate, 32/3µm, multi-vacuolate and 1-septate.

Paraphyses: filiform, branched, 2µm diam, tips weakly agglutinated.

Ascus tips not staining in Melzer's Iodine.

Excipulum: soft, black, covering hymenium when young.

Many thanks for any comments.

Re : disco on Abies cone
This has been identified as Colpoma crispum. It's more usually found on dead branches of the same host.

Dear Malcolm

thanks for this result. It is possible, though I think the spores are with 3 µm a bit wide when comparing available data.

Re : disco on Abies cone
It was identified by Paul Cannon at Kew. He had the material but I don't know if he measured the spores himself. Some of my measurements have been a bit wider than they should be - perhaps caused by the mounting medium. (I know it's always best to use water!!)

In water the spores would be wider, but it could be that pressure made the spores wider.
