ORIG DESCRIPTION* ORIGINAL DIAGNOSIS: (English translation, l.c., p. 157): Sori spherical, subspherical or oval in shape; [formed by] agglomeration of several ten's of small spherical or polygonal spores. Spores without pits [=pores?]; wall thick; surface uneven. Sori preserved in the cells of Permocalculus, sometimes causing the parasitized cells to swell. Probably having affinity to the cystosorous forms produced by plasmodiophoraceous fungi.

Monotypic.

K&J REMARKS Due to time restraints, Kalgutkar and Jansonius (2000) were unable to have the full Chinese description of the type species translated into English. Interested readers may refer to the original paper.

It appears from the figures (pl. 2, figs. 3-7 and text-fig. 1) that the somatic phase is probably comprised of cystogenous plasmodia, and the cystosori are formed by a number of cysts agglutinated together. Cysts, at the time of germination, give rise to zoospores that are capable of infecting the host tissue.

The spores are 1.5-5 µm in diameter; they form clusters with a diameter of 10-20 µm.
TYPE TYPE: Sorosporonites parasiticus Mu Xinan 1977, p. 152, pl. 2 fig. 3.
