These adaptations enable it to occupy niches too harsh for vascular plants or mosses, reducing competition in these environments. [17] The podetia show a high degree of variability, ranging from entirely decorticate surfaces to densely squamulose ones, allowing the lichen to adapt to a wide range of environmental conditions and substrate types.
In biology, a spore is a unit of sexual (in fungi) or asexual reproduction that may be adapted for dispersal and for survival, often for extended periods of time, in unfavourable conditions. [1] Spores form part of the life cycles of many plants , algae , fungi and protozoa . [ 2 ]
The second class – Paragregarea – was created for the archigregarines, Stenophorida and a new order – Velocida which itself was created for Urosporoidea superfam. n. and Veloxidium. The third class was created – Squirmida – for Filipodium and Platyproteum.
The sporocarp (also known as fruiting body, fruit body or fruitbody) of fungi is a multicellular structure on which spore-producing structures, such as basidia or asci, are borne. The fruitbody is part of the sexual phase of a fungal life cycle, [1] while the rest of the life cycle is characterized by vegetative mycelial growth and asexual ...
Diagram showing the alternation of generations between a diploid sporophyte (bottom) and a haploid gametophyte (top) A sporophyte (/ ˈ s p ɔːr. ə ˌ f aɪ t /) is the diploid multicellular stage in the life cycle of a plant or alga which produces asexual spores.
Aspergillus (/ ˌ æ s p ər ˈ dʒ ɪ l ə s /) is a genus consisting of several hundred mold species found in various climates worldwide.. Aspergillus was first catalogued in 1729 by the Italian priest and biologist Pier Antonio Micheli.
Fruiting bodies have a short stalk from which arises a spore-bearing structure (the receptaculum) of 5–8 arched arms. These arms, initially joined at the top, disconnect and curve irregularly to expose the inner surface of each arm, which is covered with green spore-containing gleba. Spores are 3–4 × 1–1.5 μm.

The term "spore" is used to describe a structure related to propagation and dispersal. Zygomycete spores can be formed through both sexual and asexual means. Before germination the spore is in a dormant state. During this period, the metabolic rate is very low and it may last from a few hours to many years.
