Protopannaria pezizoides
species of lichenized fungus
Protopannaria pezizoides, the gray moss-shingle, is a species of squamulose lichen in the family Pannariaceae. It was first described scientifically by the German botanist Georg Heinrich Weber in 1778. It has a long and complex taxonomic history, and has an extensive synonymy. It was transferred to the genus Protopannaria by Per Magnus Jørgensen and Stefan Ekman in 2000; it was assigned as the type species of the genus. Protopannaria pezizoides is widespread, with a continental distribution that includes Africa, Asia, North America, and Oceania. The lichen thrives in moist and/or humid conditions, predominantly found on soil and at the bases of trees, and occasionally on rocks, within forested and arctic-alpine settings. Its photobiont partner is from Nostoc, a genus of cyanobacteria. It does not contain any lichen products, and all standard chemical spot tests are negative.
“Protopannaria pezizoides” enters the record as species of lichenized fungus. Crown Archives preserves that source wording while asking what Protopannaria, pezizoides and species can confirm, complicate or overturn.
Why this record matters
“Protopannaria pezizoides” is worth following because a concise public description often conceals a longer documentary argument. Here, Protopannaria, pezizoides and species provides the most credible route into that argument.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Nov 3, 2025. The linked authority identifier is Q10512253. The first chronological checks are 1778 and 2000.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
