Box without historic collection number, barcode [ BM001089762 ]: leg. anon., Hertf.VC 20 [= Hertfortshire, Vicecounty 20]: only a small sample of capillitium and spores was taken for study by LM and SEM. The capillitium is orange in mass, yellowish-brown by LM. Elaters 4–5 µm in diam., with 3–4 regular spiral bands interconnected by transverse striations and showing spines that are difficult to observe in LM, but distinctive under the SEM. Elaters with very short pointed free ends up to 5 µm in length. Spores are globose, 8.8‒10.6 × 8.6‒10.6 µm, av. 9.7 × 9.7 µm, Qav = 1 (n = 25), yellowish in transmitted light and reticulated. Under the SEM the ornamentation is of the simple reticulate type, the reticulum is made up of 8–10 meshes of different sizes per semicircle, with low muri.
