Amandinea
genus of fungi
Amandinea is a genus of lichenized fungi in the family Caliciaceae. Genetic studies indicates that the genus Amandinea and Buellia are the same, although this is not widely accepted.
Taxonomy
The genus was originally circumscribed by Maurice Choisy in 1950, with Amandinea coniops assigned as the type species. However, the name was published invalidly because it was not accompanied by a Latin description or diagnosis, a requirement of the nomenclatural rules of the time. Christoph Scheidegger and Helmut Mayrhofer published the genus name validly in 1993. The generic name honours French Madame Amandine Manière, an acquaintance of Choisy.
Description
Amandinea species have a crustose thallus ranging from cracked (rimose) to slightly blistered (bullate). The internal white layer (medulla) is iodine-negative (I−), meaning it does not turn blue in the standard iodine test and is therefore non-amyloid. The photosynthetic partner is a chlorococcoid green alga, i.e. with small, spherical cells.
“Amandinea” enters the record as genus of fungi. Crown Archives preserves that source wording while asking what Amandinea, genus and fungi can confirm, complicate or overturn.
Why this record matters
“Amandinea” is worth following because a concise public description often conceals a longer documentary argument. Here, Amandinea, genus and fungi 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 20, 2025. The linked authority identifier is Q4739822. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1950 and 1993.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
