Sphagnum cuspidatum capitulum. "Sphagnum cuspidatum" is a dominant species in the bogs that it inhabits. In wetlands, they consume methane through symbiosis with partly endophytic methanotrophic bacteria, leading to highly effective in situ methane recycling preventing large-scale methane emission into the atmosphere. The bacteria are present in the hyaline cells of the plant. Sometimes, Sphagnum moss can be infected with another type of fungus that can cause sporotrichosis. The other fungus can enter the body through cuts or scrapes on the skin, and will then cause ulcerous skin lesions. It is therefore advised to wear gloves and long sleeves when handling sphagnum
Type (biology) species of the section ... After studying the diverse forms, I came to consider them as belonging to the one and the same specific type. In botanical nomenclature, a "type" ("typus", "nomenclatural type"), "is that element to which the name of a taxon is permanently attached." (article 7.1) In botany a type is either a specimen or an illustration. A specimen is a real plant (or one or more parts of a plant or a lot of small plants), dead and kept safe, "curated", in a herbarium (or the equivalent for fungi). Examples of where an illustration may serve as
