ENDOPHYLLACE^E 333 



The fungus in the cecidium-stage forms rounded swollen pustules on 

 the leaves or extensive patches on the stems. Every shoot of the year is 

 usually attacked and contorted, and in August is covered and made 

 conspicuous by a copious development of the orange spores. The teleuto- 

 spores have not been detected in this country. They are remarkable for 

 their mode of germination — the basidium is formed internally as in 

 Colcosporium ; this then emerges through a rupture at the base of the 

 spore and produces its large nearly sessile basidiospores externally, one 

 from each cell. 



Distribution : France, Germany, Italy, Corsica, Tunisia, 

 Algeria. 



ENDOPHYLLACE^E 



Teleutospores in long chains, surrounded by a peridium, 

 which is formed like that of a typical secidium of P actinia from 

 the peripheral cell-rows, but is sometimes less strongly devel- 

 oped ; spores separated by intercalary cells, produced from a 

 fusion-cell, but germinating as soon as mature by a typical 

 basidium and basidiospores ; germ-pores not perceptible ; spore- 

 wall coloured, verruculose. Spermogones present ; both kinds 

 of sori subepidermal.
