Template:Short description Template:Automatic taxobox

Bacidina is a genus of crustose lichens in the family Ramalinaceae.[1]

Taxonomy

The genus was circumscribed by Czech lichenologist Antonín Vězda in 1990, with Bacidina phacodes assigned as the type species. Vězda included 11 species in Bacidina, which was originally classified in the Lecideaceae. These species had previously been placed in genus Bacidia.[2]

Description

Bacidina species are crustose lichens, forming thin, often inconspicuous thalli that may be smooth, cracked, warted, or Template:Lichengloss. Some species develop specialised reproductive structures such as soredia, isidia, or microsquamules. The thallus is typically pale in colouration, ranging from whitish and pale green to greyish or fawn. The photosynthetic partner (Template:Lichengloss) consists of Template:Lichengloss algae, which have roughly spherical (Template:Lichengloss) to broadly ellipsoidal cells.[3]

The reproductive structures, or apothecia, are relatively small, usually up to 1 mm in diameter, and can be flat or strongly convex. They lack a distinct Template:Lichengloss but have a well-developed Template:Lichengloss, which is composed largely of thick-walled cells with isodiametric to ellipsoidal Template:Lichengloss. This distinguishes Bacidina from Bacidia, which has a true exciple made of radiating hyphal tissue with narrow lumina. The hymenium, a spore-producing layer, reacts with iodine (I+) to stain blue. The underlying Template:Lichengloss varies in colouration from colourless to pigmented. The paraphyses within the hymenium are generally few in number, sometimes branched, and often have swollen tips.[3]

The asci, which produce the Template:Lichengloss, are club-shaped (Template:Lichengloss) to cylindrical-clavate in shape and typically contain eight spores. Most Bacidina species have asci of the Bacidia type, characterised by an apical dome that stains dark blue in K/I with a pale, conical apical cushion. In some species, the ascus resembles the Biatora type, which has a darker-staining zone around the apical cushion. The ascospores are colourless, generally three- or more-septate at maturity, and often Template:Lichengloss (thread-like), Template:Lichengloss (needle-shaped), or sigmoid (curved like an "S"), though some species have spores that are cylindrical to fusiform. A distinct outer spore coating (Template:Lichengloss) is absent.[3]

Asexual reproduction occurs through conidia, which are produced in small, often Template:Lichengloss or sessile pycnidia. The conidia are colourless and vary in shape, with some species producing septate conidia. Bacidina species do not contain secondary metabolites that react with common chemical spot tests (C–, K–, KC–, Pd–, I–, UV–), but their apothecia and pycnidia may contain a variety of pigments.[3]
