  1. Voucher numbers are linked to accession numbers for sequences deposited at Genbank [29]. In cases where alternate voucher numbers appear in brackets, these accessions were used for phylogenetic analysis. CV% indicates the mean coefficient of variation of the 2C DNA peak for each specimen. Reproductive mode was determined from spore number per sporangia, and some prothalli observations [29]. MO1 and MO2 refer to the two clades within the A.monanthes complex identified by the phylogenetic analysis of Dyer et al. [29].
  2. *Data for these species (which belong to the A. castaneum clade) were not considered to be reliable as they were estimated from 2 year old silica dried material and were therefore not included in analysis.
  3. Data for these species were estimated from 6 month old silica dried material.
