Wikipedia:WikiProject Fungi/Lichen task force

Scope

As of 7 November 2026, there are 5,493 articles within the scope of WikiProject Lichen task force, of which 3 are featured and 64 are good articles. This makes up 0.08% of the articles on Wikipedia, 0.03% of all featured articles and lists, and 0.14% of all good articles. Including non-article pages, such as talk pages, redirects, categories, etc., there are 19,458 pages in the project.

• Lichen covers all lichen taxa (species, genera, families, etc.) and fungi typically studied by lichenologists, such as lichenicolous fungi. The task force also covers other articles within the spectrum of lichenology, such as lichenological terminology, notable lichenologists and chemical substances made by lichens.
• Coverage also includes all algal taxa that occur in lichens.
• How many lichen taxa are there? This question was explored by Lücking et al. in the publication "The 2016 classification of lichenized fungi in the Ascomycota and Basidiomycota – Approaching one thousand genera" doi:10.1639/0007-2745-119.4.361, and a subsequent "Corrections and amendments" followup in the following issue (doi:10.1639/0007-2745-120.1.058). After these revisions, the authors concluded "the number of lichenized species is now tabulated at 19,409 and the number of fungal genera, families, and orders including lichens at 1,002, 119, and 40, respectively". In recent decades there have typically been a couple hundred new lichen species described each year. As of 2018, the number of accepted lichenicolous fungi was 2319, including "2000 obligately lichenicolous species, subspecies or varieties, 257 lichenicolous lichens and 62 facultatively lichenicolous taxa". doi:10.1639/0007-2745-121.3.340
