Economic growth is an increase in real GDP. It means an increase in the value of goods and services produced in an economy. The rate of economic growth measures the annual percentage increase in real GDP.
Asexual reproduction in ascomycetes (the phylum Ascomycota) is by the formation of conidia, which are borne on specialized stalks called conidiophores. The morphology of these specialized conidiophores is often distinctive of a specific species and can therefore be used in identification of the species.
These phyla and the other five that have been proposed are mainly differentiated based on sexual reproductive structures. Phylum Ascomycota. The largest phylum of fungi is Ascomycota. These fungi are called ascomycetes or sac fungi because their meiotic spores (ascospores) are found in a sac called an ascus. This phylum includes unicellular yeasts, lichens, molds, truffles, numerous filamentous fungi, and a few mushrooms. This phylum contributes fungi used to make beer, bread, cheese, and medicines.
