Trichophaea gregaria?

Malcolm Greaves, 04-07-2017 15:48

This was found in mud at the side of a woodland track.
The spores are 19-20 x 10 ellipsoid/fusiforme.
The hairs thick walled, septate, some slightly swollen towards the base and up to 300µ long. Paraphyses thin and slightly swollen at the tip.
Trichophaea gregaria seem a good fit but I could find no ornamentation on the spores even in LCB.
Am I right with Trichophaea and could it be T gregaria?
Thanks
Mal

Re : Trichophaea gregaria?

Are your sure that the spores are mature?
Usually T. gregaria has spores longer than 20 µm, ornamented by small cyanophilous warts.

Re : Trichophaea gregaria?

Thanks Nicolas
I will try for a better spore drop and check the results.

Re : Trichophaea gregaria?

A much better result this time. Spores (19) 21.04 (23.4) x (9.4)10.66(11.56) with ornamentation which according to the diagrams in the Bronckers key looks more like T pseudogregaria.

Ps could it possibly just be humaria hemispherica? The largest apothecia was 2.9mm across
