Some groups, such as the conjugating fungi, consist of single-celled organisms in which each cell has hundreds or thousands of nuclei. Abundant evidence shows that many tropical fungi remain to be discovered based on species accumulation curves of fungi collected in plots Aime et al.
Spores are similar to seeds but much smaller and simpler since they usually contain only one or two cells.
In addition to most lichens and so-called "imperfect fungi," about 33, species of unicellular yeasts, green and black molds, powdery mildews, morels, cup fungi, and ascotruffles "true" truffles belong to this phylum.
Most species feed by secreting enzymes, which partially break down the food. Auricularia spp. Repeated host switching, however, has occurred within termite clades as reflected in the phylogenetic trees of termites and associated fungi Aanen et al.
As human and animal pathogens, fungi cause infections that range from the vexing athlete's foot, yeast infections to life threatening histoplasmosis.
Some yeast cells bud and reproduce asexually. Because of the great discrepancy between known and estimated fungal species numbers, mycologists have a renewed interest in fungal discovery. Today, most of the bread, cakes, cookies, and the like consumed by the public are prepared from leavened batter.
Aanen, D. In the s, straw mushroom cultivation began in the PhilippinesMalaysiaand other Southeast Asian countries.
Mutualism —Close relationship of two or more organisms, which typically involves exchange of food or other resources. Not a MyNAP member yet? J Am Vet Med Assoc c , — They resemble green plants as generally they have definite cells walls, they are usually nonmotile, although they may have motile reproductive cells, and they reproduce by means of spores.
