| Voucher Notes | Identified by R. Bandoni as Helicogloea lagerheimii, but not this sp. based on septum analysis, which indicates that it is different from the H. lagerheimii identified by Weiss, M., et al., 2004, Frontiers in Basidiomycote Mycology, Agerer, R., Piepenbring, M., Blanz, P., eds, p.7-48 |
