Index Fungorum: "The identifiers are unique for any name independent of where they were issued. For example, an identifier issued by Index Fungorum will resolve via an Index Fungorum URL – http://www.indexfungorum.org/Names/NamesRecord.asp?RecordID=550000 – and a MycoBank URL – http://www.mycobank.org/MycoTaxo.aspx?Link=T&Rec=550000". (Cited from https://www.indexfungorum.org/names/IndexFungorumRegister.htm).

IPNI: The IPNI LSID (Life Science Identifier) is a unique identifier used to represent scientific names of plants in the International Plant Names Index (IPNI). IPNI is a global database of plant names that provides information about the scientific names of plants, including their synonyms, authorship, publication details, and other related information. The LSID is a standardized format for representing these names and their associated data in a machine-readable way. An LSID consists of several parts, including a prefix that identifies the issuing authority (in this case, IPNI), a namespace that identifies the type of data (usually "names"), and a unique identifier for the specific record. For example, a typical IPNI LSID might look something like this: urn:lsid:ipni.org:names:77108241-1. In this LSID, "ipni.org" is the domain of the issuing authority (IPNI), "names" indicates that it's a record for a plant name, and "77108241-1" is the unique identifier for that specific record.
