Microhongos Comunes de Costa Rica y Otras Regiones Tropicales / Common Microfungi of Costa Rica and other Tropical Regions (Ascomycota, Pezizomycotina, Sordariomycetes)

Fungi have been poorly studied despite their economic and ecological importance. Worldwide, there are an estimated 1,500,000 species and only approximately 5-10% are known. Of that percentage (some 72,000 species), the majority belong to the taxonomic group Ascomycota (ascomycetes). Most of the ascomycetes are so small that they can only be seen with a magnifying glass or microscope. For this reason, most ascomycetes are also known as microfungi. Our objective is that this illustrated guide can also be useful for biologists, naturalists, scientists, students and the general public because it illustrates a little-known biodiversity of Costa Rica and other tropical regions.
