Biology:Baculifera
Baculifera is a genus of lichens in the family Caliciaceae.[1] It was circumscribed in 2000 by Bernhard Marbach and Klaus Kalb. Species in this genus are characterized by having bacilliform conidia typically measuring 8–11 μm long, and a non-[[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] hymenium. The genus is roughly similar in morphology to Buellia.[2]
Description
The thallus is crustose: it forms a thin, [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] crust that can be smooth and continuous or break into patches, and in some species it lies mostly within the bark ([[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]). It lacks a distinct outer [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] ([[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]), and a faint marginal [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] may be present. The [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] is a unicellular green alga with roughly spherical cells about 8–18 μm across.[3]
Sexual reproductive structures are apothecia that are [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] (with only a [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], not a [[Glossary of lichen terms#{{biology:{1}}}|thalline]] one) and [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]. The [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] is black and flat, wavy, or slightly convex, without a whitish frosting ([[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]). The [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] is persistent, the same colour as the disc, and cup-shaped in section, appearing opaque dark brown. The hymenium is clear and not filled with oil droplets (hyaline, not [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]) and carries a dark, pigmented epithecial layer. Paraphyses are [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] or only sparsely branched and tend to stick together in a KOH test; their tips bear a distinct, internally pigmented cap. The asci are club-shaped and usually contain 3–8 spores. Their apical cap ([[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]) is well developed and amyloid (staining blue with iodine), sometimes with a slightly more intensely amyloid band beside a broad or narrow conical central plug (a masse axiale) whose rounded apex usually extends through the tholus.[3]
The ascospores are brown to grey-brown, ellipsoid, sometimes slightly curved, and divided by 1–3 cross-walls. They lack a clear outer [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]], and occur in two main forms: a Buellia-type with fairly even walls and little thickening, and a Callispora-type with slight to strong wall thickenings near the ends and the middle. Asexual reproduction occurs in immersed pycnidia that produce short, rod-shaped conidia ([[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]). In chemical tests, many species contain atranorin and/or norstictic acid, while others have no detectable secondary metabolites.[3]
