Stephanoascales

Starmerella meliponinorum, from Teixeira et al. (2003).

Belongs within: Saccharomycotina.

The Stephanoascales, originally proposed as a grouping for saccharomycetous yeasts with galactose in the cell walls, but more recently restricted to a smaller group distinguished by molecular data (some species of which lack galactose). Members of the Stephanoascales lack extracellular amyloid compounds (Schweigkofler et al. 2002).

Dipodascales

Wickerhamiella domercqiae, photographed by Linda Barnett.

Belongs within: Saccharomycotina.

The Dipodascales are a group of yeasts united by molecular data. Their cell walls may be composed of glucose, mannose and galactose, or of glucose and mannose alone, and they lack extracellular amyloid compounds (Schweigkofler et al. 2002).
