Geoglossum
Malcolm Greaves, 13-11-2015 13:36
Malcolm GreavesA huge number of these were in short grass on a heathland site near me. They seem to fit with G umbratile except for the short spores which are 50-60µ long.
Would this be within a reasonable range for the species or is there another species I should be looking at?
Thanks

Re : Geoglossum umbratile
Geoglossum umbratile spore size is highly variable (30-90 x 4.5-6.5 microns). The septa in the paraphyses are not constricted while the septa in Geoglossum simile and G. pygmaeum both are constricted. Geoglossum simile and Geoglossum glabrum have paraphyses that are closely septate in the upper portions.

Re : Geoglossum

The asci, paraphyses and inmature spores guttulation are typical of G. fallax, but shorter spores, as HB6543 of Zotto!

Re : Geoglossum
Thanks Michael and Sabino.
Looking at Zotto's great descriptions I think that as I could find no mature spores with more than 7 septae and the paraphyses were quite swollen I think G umbratile is more likely. I will note for future that the spores can be more variable than some descriptions say.

Re : Geoglossum
Hi Iglesias
I have very little experience of Geoglossum so if this is typical G fallax what differences should I look out for in G umbratile?
Thanks

Re : Geoglossum
My understanding of Geoglossum fallax is that it is notable for its brown rather than black fertile surface color, a finely scaly stipe, gnerally hyaline spores that only tardily become septate and turn smoky, The spores are initially non-septate, then 3-septate and finally 7-12 septa. Paraphyses are 5-6 microns, cylindric, sparingly to moderately septate, not constricted or only moderately constricted at the septa and strongly curved or coiled in the upper part. The paraphyses are very similar to those of G. umbratile. Some collections of G. umbratile are viscid. G. umbratile fruitbodies are dark brown to black
