Geoglossum query
Watt John, 19-11-2024 14:48
Scoring the characters on Mal's Tombio key actually comes up with Glutinoglossum heptasporum, (13.1) but I thought the surface was not shiny or glutinous. (Specimen shown is a bit dried out.)All the mature spores were 7 -septate and 90-95 mc. Asci were blue in Lugols, 8 spored. Paraphyses were mostly non-septate ( cf cookeanum which was next highest score at 10.) Maybe it's just fallax (score of 6)?  Any thought appreciated many thanks. It was growing in a cemetry in lowland Lancashire.

Re : Geoglossum query
Make a squash of a small section of the stem. This will show the gelatinous layer if it is a Glutinoglossum. A few more photos of the paraphyses might help. Just to say I have found what I called fallax which had the majority of spores 7 septate.

Re : Geoglossum query
Thanks. The cross section doesn't seem to show a glutinous layer, which I've not seen before mind you. But fallax likely I'd say.
