Another manifestation is the production of light or Bioluminescence, due to the oxidation of a suitable substrate and the interaction of two specific substances that adopt the demonic names of luciferin and luciferase. The efficiency of this combustion is very high, since the amount of energy that is lost as thermal radiation is minimal. Despite being generated in a combustion, it is not capable of raising the temperature even one millionth of a degree. It is therefore a flame that does not give heat, being known as "cold light".

Arbuscular mycorrhizas are characterized by the formation of unique structures, arbuscules and vesicles by fungi of the phylum Glomeromycota. AM fungi help plants to capture nutrients such as phosphorus, sulfur, nitrogen and micronutrients from the soil. It is believed that the development of the arbuscular mycorrhizal symbiosis played a crucial role in the initial colonisation of land by plants and in the evolution of the vascular plants.

The flesh of a puffball is called the gleba, and when immature (and edible) it is pure white and has the texture of marshmallow. Once mature the gleba’s color changes to yellow and brown and should not be eaten at this stage because of its poor taste and possible toxicity. In addition to a change in color the gleba becomes powdery at maturity due to the spores and capillitium (sterile threads that hold the spores).

Under the name of Tibi, the original granules live in Opuntia ssp feeding on the sugary excretions (fruits) of these cacti. In Oaxaca, they are popularly known as seaweed or granillo, and are generally used domestically. Later, the granules of this culture, also known as cabaiasis, were named tibicos. Some sources call them Chinese mushrooms and others point to Japan as its origin. Reference is also made to Tibet, where the word tibicos would come from.
