Plage (mycology)
A plage is a clear, unornamented area on the basal area of an otherwise ornamented spore. It is characteristic of spores from the euagaric genus ''Galerina''.

Galerina Marginata Plages
''Galerina'' is a genus of small brown-spore saprobic fungi (colloquially often ''mushrooms''), with over 300 species found throughout the world from the far north to remote Macquarie Island in the Southern Ocean. The genus is most noted for some extremely poisonous species which are occasionally confused with hallucinogenic species of ''Psilocybe''. Species are typically small and hygrophanous, with a slender and brittle stipe (mycology), stem. They are often found growing on wood, and when on the ground have a preference for mossy habitats. ''Galerina'' means ''helmet-like''. Taxonomic definition The genus ''Galerina'' is defined as small mushrooms of wikt:mycenoid, mycenoid stature, that is, roughly similar in form to ''Mycena'' species: a small conical to bell-shaped pileus (mycology), cap, and lamella (mycology), gills attached to a long and slender cartilaginous stipe (mycology), stem. Species have a pileipellis that is a cutis, and ornamented spores that are brown in depo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spore
In biology, a spore is a unit of sexual or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. Spores form part of the life cycles of many plants, algae, fungi and protozoa. Bacterial spores are not part of a sexual cycle, but are resistant structures used for survival under unfavourable conditions. Myxozoan spores release amoeboid infectious germs ("amoebulae") into their hosts for parasitic infection, but also reproduce within the hosts through the pairing of two nuclei within the plasmodium, which develops from the amoebula. In plants, spores are usually haploid and unicellular and are produced by meiosis in the sporangium of a diploid sporophyte. Under favourable conditions the spore can develop into a new organism using mitotic division, producing a multicellular gametophyte, which eventually goes on to produce gametes. Two gametes fuse to form a zygote which develops into a new s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Euagaric
The fungal order Agaricales, also known as gilled mushrooms (for their distinctive gills) or euagarics, contains some of the most familiar types of mushrooms. The order has 33 extant families, 413 genera, and over 13,000 described species, along with six extinct genera known only from the fossil record. They range from the ubiquitous common mushroom to the deadly destroying angel and the hallucinogenic fly agaric to the bioluminescent jack-o-lantern mushroom. History, classification and phylogeny In his three volumes of ''Systema Mycologicum'' published between 1821 and 1832, Elias Fries put almost all of the fleshy, gill-forming mushrooms in the genus '' Agaricus''. He organized the large genus into "tribes", the names of many of which still exist as common genera of today. Fries later elevated several of these tribes to generic level, but later authors—including Gillet, Karsten, Kummer, Quélet, and Staude—made most of the changes. Fries based his classification on ...
