synonyms

Gäumann presents arguments why Melampsora lini, only on fairy flax, and liniperda, on all other Linum species, should be taken as two valid species; his reasoning is accepted by Klenke & Scholler. However, many modern authors unite both under the name lini. Incomprehensible, and possibly simply erroneous is the position of the Index Fungorum (2016), that also unites the two species mentioned under lini, but also acepts as valid two more species: lini-cathartici Kuprevič, 1957 and lini-usitatissimi Kuprevič, 1957.
