Bacidia Pycnidiata
''Bacidina pycnidiata'' is a species of crustose lichen in the family Ramalinaceae. It is widely distributed in Europe and North Asia. It is characterised by its whitish or cream-coloured pycnidia with long and ostiole, ostiolar necks. Taxonomy The lichen was species description, formally described as new to science in 2006 by lichenologists Paweł Czarnota and Brian John Coppins. The type (biology), type specimen was collected by the first author west of the village of Bílá Voda, near a marble quarry (Eastern Sudetes, Golden Mountains (Sudetes), Golden Mountains, Czech Republic). There, in a mixed spruce-ash (tree), ash forest at an altitude of about , it was found growing over bryophytes on marble rocks. The botanical name, species epithet ''pycnidiata'' refers to the long-necked pycnidia that are characteristic of this species. The lichen was originally placed in the genus ''Bacidia'' based largely on the characteristics of the apothecia. The authors noted, however, that som ...

Apothecia
An ascocarp, or ascoma (), is the fruiting body ( sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia). Classification The ascocarp is classified according to its placement (in ways not fundamental to the basic taxonomy). It is called ''epigeous'' if it grows above ground, as with the morels, while underground ascocarps, such as truffles, are termed ''hypogeous''. The structure enclosing the hymenium is divided into the types described below (apothecium, cleistothecium, etc.) and this character ''is'' important for the taxonomic classification of the fungus. Apothecia can be relatively large and fleshy, whereas the others are microscopic—about the size of flecks of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
