BMC Genomics

Table 1 Matrix of phenotypic traits scored for the five Oedogoniales strains. Character state definitions are below, unknown character states are notated as “?”. Polymorphic conditions are indicated with multiple state numbers

1-Habit: unbranched filaments (0); branched filaments (1). 2-Sex differentiation: monoecious species (0); dioecious, macrandrous species (1); dioecious, nannandrous, gynandrosporous species (2); dioecious, nannandrous, idioandrosporous (3). 3-Oogonium’s morphology: subglobose (0); obovoid-globose (1); obovoid to subovoid (2). 4-If oospore filling the oogonium: same as oogonium, nearly or completely filling the oogonium (0). 5-Oospore wall ornamentation: smooth (0); outer layer reticulate and dentate, teeth spreading form reticulations (1). 6-Type of oogonial aperture: pore (0); circumcision (1). 7-Position of oogonial aperture: median to inframedian (0); superior (1). 8-If the antheridia single or continuous: single (0); 1 or 2 continuous (1); 2–7 in a series (2). 9-The number of sperm and the way of division: sperms 2, division horizontal (0); undefined (1). 10-Morphology of dwarf male: absent (0); on suffultory cells, stipes slightly curved, antheridia exteriors, 1 or 2 continuous (1); 11-Suffultory cells: uninflated (0); slightly inflated or inflated (1). 12-Basal cell: elongated (0); sub-hemispherical (1); undefined (2). 13-Terminal cell: obtuse (0); apiculate (1); 14-Vegetative cell’s morphology: cylindrical (0)
