Meira

Meira Boekhout, Scorzetti, Gerson & Sztejnb. 2003, in Boekhout et al., International Journal of Systematic and Evolutionary Microbiology, 53(5), 1655-1664 (2003).

Etymology: Meir’a. Hebrew fem. n. meira light, to express the feeling of three of the authors (A. S., U. G., A. G.) after the phylogenetic position of the fungi was resolved, and also named after the wife of A. G.

Diagnosis: Anamorphic fungi, belonging phylogenetically to the Exobasidiomycetidae (Ustilaginomycetes, Basidiomycota), with dimorphic colonies. Initial yeast-like growth with fusiform cells showing polar budding on an acropetal rachis. Septate hyphae hyaline, usually with the cytoplasm retracted in cells, separated by lysed cells. Sterigma-like outgrowths, frequently occurring near the septa, give rise to short chains of fusiform blastoconidia. Thin aerial mycelium, made up of these blastoconidia, give the colony a somewhat velvety appearance. myo-Inositol is not assimilated and extracellular starch is not produced, DBB and urease reactions are positive.
