The spores are more or less globose, smooth or slightly verrucose, eqquiped with short pedicel, light coloured (maybe pallid ochraceous) with diameters between 3.3 and 4.2 µm. This fits very well _Disciseda candida (var. candida) in the paper of Z. Moravec. The only point in doubt is the diameter of the capillitium hyphae, that is mentioned there to be only 2.5 µm thick. However, the recent paper by Navarro, Esqueda&Moreno (Ref. 2), say that the diameter of all hyphae are in the range 4-8 µm. Moreover, there are no other species with so small spores. Therefore, I think this is Disciseda candida.
