Lichen Taxonomy

This week a new issue of the journal Opuscula Philolichenum came out. It contains two pieces to which I contributed. The first is an announcement of the new International Committee for the Nomenclature of Lichens and Allied Fungi (ICNLAF), which was formed only very recently (Lendemer et al. 2012). The second is an annotated phylogenetically based summary of lichen taxonomy that I have put together based on the system in use at the New York Botanical Garden (NYBG) (Hodkinson 2012). This will be up on the internet in a format that can be continually updated as our understanding of the organisms evolves. Hopefully it can serve as a useful guide for lichen herbarium/data managers wishing to arrange taxa within a higher-level framework.

Here is the official announcement from the editor:
"The latest issue (volume 11, number 1) of Opuscula Philolichenum is now available online at free of charge as is tradition. This is the first volume to be published in the new age of electronic publication as sanctioned in Melbourne last year. As was noted in the previous issue, the journal has ceased its print run (although one copy is still deposited in the library at NYBG). Volumes will also now consist of multiple numbers, published throughout the year.
"The current issue comprises five contributions covering a diverse array of topics. This includes a higher level taxonomic scheme for lichen-forming fungi that synthesizes current literature. The system may be particularly useful to those wishing to organize herbaria using a phylogenetic system as is common practice in vascular plants. Also included are contributions to our understanding of Hypogymnia in eastern Asia, Parmeliella in South America, and Acarospora in South America. Those who have been following the changes in generic concepts in Acarosporaceae, particularly pertaining to Silobia, will be interested in the discovery by Linda in Arcadia and Kerry Knudsen that Myriospora is actually an earlier available name for Silobia. The authors make the appropriate new combinations and place the taxa previously assigned to Myriospora in a new genus.
"In addition to the above contributions the issue contains the notice of the formation of an International Committee for the Nomenclature of Lichens and Allied Fungi. A group that that aims to work with IAL and various bodies (ICNF, NCF) in the event that matters of nomenclatural governance are formally delegated to special committees by the IBC/IAPT."
