Specimen notes
Public Note:
Clearly atramentarius/acuminatus group. Veil not seen. This has spores with quite definite pale brown caps over large germ pores (like some Macrolepiota). Is it something different? Spores (including cap) 8.4-9.9(9.1) SD0.6, n=14 X 4.6-5.3(5.1) SD0.2, n=14. Germ pore 1.7-2.2(1.9) SD 0.15. Spore width size consistent with acuminatus but morphology closer to atramentarius. The large germ pore with cap is not consistent with either of these taxa. We should check for pore cap in other collections of 'atramentarius'.
