Geoglossum

Di Napier, 08-11-2022 16:24

A Geoglossum (I think, but not confident) from a churchyard in Warwickshire, UK (with many waxcaps present too). It seems perhaps closest to Geoglossum umbratile, but I'm not sure whether the spores are a bit too narrow (around 5 um). Spores are 75-102 um long (most are 80-90), 7-septate. A few were seen with fewer septa, but they were paler and did not look mature. Paraphyses tips are curved/hooked - often hockey-stick shaped. Asci about 250 x 25 um. c 8 cm tall. Many thanks for any help.

Hi Di
I would be happy to call that G umbratile

Re : Geoglossum

Thank you, that's great - I'll go with that then. I used your FSC identikit. It's really helpful.
