Well-drained; Rocky 

Fronds, or portions of fronds, containing ripe spores can be placed in a paper bag which is left upright in a dry and draught-free place. Spores should begin to release immediately and all spores are released within days unless the species has tough, leathery fronds. Spores settle at the bottom of the bag.After sowing specks of green appear within 2-4 weeks. These are the young prothalli and during the next 6-12 months they are at risk from overcrowding and pathogens. When the first fronds appear the sporelings can be slowly hardened by gradual removal of the container cover. Great care must be taken to avoid drying out. Prick out sporelings when the second frond appears. Suitable below powerlines. 

Spores found in sori which are elongated, protected when young by the reflexed margin of the pinnae. spores collected when mature on the frond. unripe sori are generally light green then change to yellow- ish brown and to dark brown or black when mature 

 

 

 

Sow spores into a pot in a water retaining medium with good drainage. Sterilise medium & containerwith boiling water and sow spores bysprinkling a small amount onto the surface of the medium.
