General environment
This is a brackish species.

Description
The plants are up to 100 mm high, and with 1-20 plants together from the same oospore. Plants are encrusted or nor encrusted. The axis is 150-600 µm in diameter. Whorls 1-6, only the first, protonemal whorl has 1-6 sterile, undivided branchlets, and 4-22 fertile branchlets which are up to 40 mm long. The other 1-5 whorls have only fertile branchlets. The branchlets are normally curved inwards towards the stem. The internode between the protonemal whorl and the first whorl vary from 0.5 – 16 mm in length. There is one terminal process which is much longer than the heads, up to 90 mm long. The species is monoecious. The gametangia are conjoined at stem nodes and fertile branchlet nodes. The oogonia are up to 300 – 450 µm long, with 6-8 sharp ridges. The oospore is dark brown to black and have a granulate membrane. The antheridia are solitary or 2-4 together, 250-450 µm in diameter. When they are stipitated, the stalkcell is up to 600 µm long

Habitat
Tolypella normaniana grows on loose clay bottom in different estuarine fjords in Nordland. By ebb sea, the tidal flats which make up large areas where the alga lives are exposed to air. On these foreshore flats the alga survives in small pools or on wet bottom sediment, where the alga is fastened by its rhizoids. Tolypella normaniana is found in localities with nearly fresh – to slightly brackish water at least in summer. The salt content is considerable higher in the autumn. The species is annual and survives the winter as oospores. In Beiarnfjorden the fructification was extremely rich in July 1993, and the plants had mature red oogonia and orange antheridia. In August 1993 ripe, brown oospores were found in more localities. In November 1993 the number of ripe oospores from Beiarn- fjorden was very high, and still there were fructifying specimens, now only with oogonia.

Similar species
Tolypella nidifica. Has been considered as a subspecies of this, eg. by Wahlstedt (1875).
