Black yeast From Wikipedia, the free encyclopedia. “Black yeasts” , sometimes also black fungi, dematiaceous fungi, microcolonial fungi or meristematic fungi is a diverse group of slow-growing microfungi which reproduce mostly asexually (fungi imperfecti).he term  polyextremotolerance  has been introduced to describe this phenotype, a good example of which is the species Aureobasidium pullulans. Presence of 1,8-dihydroxynaphtalene melanin in the cell wall confers to the microfungi their characteristic olivaceous to dark brown/black colour.

Definitions &Translations The mica group of sheet silicate minerals includes several closely related materials having nearly perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet-like arrangement of its atoms. The word mica is derived from the Latin word mica, meaning a crumb, and probably influenced by micare, to glitter.
