The following is Adams' description of this species (l) 

 "The species of this genus are usually fotmd parasitic in the ovary of 

 grasses, sometirces on sedges. ITeither in Saccardo's "Sylloge Pungorum" 

 noU in Engler and Prantl's "Pflanzenf ami lien" is there any mention of 

 the member of the genus occuring on ^shes. The Sphacelia stage only was 

 found, occurring in the ovary of Juncus glaucus . and filling up its in- 

 terior with an immense number of colorless spores. The spores are oblong 

 to elliptical in shape, one-celled, 7,0-10,1^ 2.0O3.5|j,. Obtained on 17th 

 Sept. on Royal Canal bank, Co, Dublin,"

Before the formation of the sclerotia the flowers are covered 

 with a cottony growth of colorless hyphae on which are formed the conidia. 

 The sclerotium is formed here outside on the spikelet in the form of a cap- 

 like curved pod. The largest sclerotia are about three millimeters in di- 

 ameter. They are attached tightly to the spikelet sending down into its 

 ovorum and between the glumes root-like structures of hyphae. The sclerotia 

 fall down with the spikelets but xvhen they are fully ripe they are easily 

 separated from the spikelets. The sclerotia are white on the inside and 

 distinctly yellov? on the outside, having a slight "korneligrauEh". Sclerotia 

 germinate after seven months with one or two long, fine, light yellow stipes.
