Description
editThis small parasitic alga grows on the red alga Polysiphonia lanosa. It grows as an irregular sphere on the fronds of the alga, reaching no more than 1 mm in extent.[3][4][5]
Habitat
editParasitic on Polysiphonia lanosa, the filaments grow into the host.[3]
Distribution
editThe species has been reported from North Russia and the Pacific.[3] In Ireland it has been confidently recorded from counties Down, Antrim[6] and Waterford[7] and at scattered sites around the British Isles including the Shetland Islands.[8]
Reproduction
editCruciate tetrasporangia are produced all year round in the cortex. The gametangial are dioecious and are produced in spring and summer.[3]
