Mycorrhiza
Mycorrhiza (a Graeco, 'radix fungi') est consociatio symbiotica, aliquando infirme pathogenica, inter fungos et radices plantae (Kirk et al. 2001). In consociatione mycorrhizosa, fungus radices hospitis plantae intra cellulas vel extra cellulas "colonizat." Haec consociatio est gravis vitae soli pars. Mycorrhizae adsunt in 92 centesimis familiarum plantarum et in 80 centesimis specierum (Wang & Qiu 2006).

Genera mycorrhizarum
Mycorrhizae usitate in ectomycorrhizas et endomycorrhizas dividuntur, greges qui inter se differunt quod hyphae fungorum ectomycorrhizalium singulas in radice cellulas non pervadunt, cum hyphae fungorum endomycorrhizalium vallum cellularem pervadunt et membranas cellulares invaginant.

Endomycorrhizae
Endomycorrhizae sunt variabiles, et in mycorrhizas arbuscularas, ericoidas, arbutoidas, monotropoidas, et orchidaceas dividuntur (Peterson et al. 2004). Mycorrhizae arbusculares sunt mycorrhizae quorum hyphae cellulas plantarum penetrant, structuras aut vesicula (sicut ballonae) aut arbuscula (invaginationes quae ramos porrigunt) gignentes. Hyphae fungorum protoplastum (interiorem cellulae partem) revera non penetrant, sed membranam cellularem invaginant. Structura arbusculorum superficialem contactus aream magnopere auget inter hyphas et cytoplasma cellularum ad translationes nutrimentorum inter ea amplicifandas.
