I have an old collection which I initially determined as Agrocybe pediades but now I have a doubt on A. vervacti. It seems both share the same habitat and are not very different macro-morphologically. I am seeking advice from some expert here, maybe there are ways to differentiate the two species. I did not write notes about the smell, unfortunately, but the spores are large and should fit A. pediades better.
I have other microscopical images and measurements.
Spores :
| spore | |
| Spore length: range | 11 - 14.8 µm |
| Spore length: mean | 13.2 µm |
| Spore width: range | 7.1 - 9.5 µm |
| Spore width: mean | 8.5 µm |
| Spore Q factor: range | 1.4 - 1.8 |
| Spore Q factor: mean | 1.6 |
| Spore shape | Elliptical, often symmetrical in both axis (fusiform) |
| Amyloid reaction | Inamyloid |
| Spore surface | Smooth |
| A little bee | Present but inconspicuous |
| Oil bodies | Huge and conspicuous singular oil body. |
| Remarks | Not congophilous and weak cyanophilous. Germination pore evident. |
