On the general annual meeting in 2004, BLAM members for the first time elected a lichen of the year, and since 2005, both a bryophyte and a lichen of the year are elected to attract the attention of the public to these small and, in many cases, endangered organisms.

Look here for recent species of the year:
2008: Orthotrichum pulchellum and Letharia vulpina
2009: Leucobryum glaucum and Cladonia rangiferina.
2010: Polytrichum commune and Dibaeis baeomyces. 
Thuidium abietinum and Fulgensia fulgens.
2012: Buxbaumia viridis and Lobaria pulmonaria.
2013: Marchantia polymorpha and Peltigera didactyla.
2014: Hedwigia ciliata and Rhizocarpon geographicum
2015: Schistostega pennata and Psilolechia lucida
2016: Sphagnum magellanicum and Icmadophila ericetorum

Michael Lüth has created a website showing all tables of his famous Atlas of the Bryophytes of Germany Vol. I to VII ("Bildatlas der Moose Deutschlands")! Please visit to view the  nice colour plates at 700x1000 pixels resolution. This is a huge gift to all who are interested in bryophytes! Thank you very much, dear Michael!

With numerous articles by lichenologists from all over the world. In the forword entitled "Josef Hafellner – a life amongst lichens and their parasites", Martin Grube, Walter Obermayer, Helmut Mayrhofer and Toby Spribille discuss the impact of Josef Hafellners scientific work on the systematics of lichenized ascomycetes and on the knowledge
on lichenicolous fungi and highlight the the value of his extensive collections (c. 100,000 lichens including c. 8,000 lichenicolous fungi). Finally, a bibliography (1975–2016) is presented.
