Reproduction Preferences Additional InformationGametangial and tetrasporangial plants occur commonly on some shores in Devon and Cornwall but are rare in the north. The 'Time of first and last gamete' refers to the time when reproductive types occur however, some conceptacles are present throughout the year. (Irvine & Chamberlain 1994.) Assuming one layer of conceptacles is produced each year, plants up to 30 years old are reported (Edyvean pers. comm.. in Irvine & Chamberlain 1994). Reproductive types occur from October to April but tail-off into summer. It has been calculated that 1 mm x 1mm of reproductive thallus produces 17.5 million bispores per year with average settlement of only 55 sporelings/year (Edyvean & Ford 1984)
