as from the whole mass of investigated preparations^ not excepting 

 germinating spores, the dividing of nuclei was find only in ascoge- 

 nous hyphae, and even only once. It results here probably, as in 

 P. culvura, from some special conditions, which greatly impede the 

 investigation. 



Sporormia intermedia. 



Sporormia intermedia is found frequently, but it is easy to miss 

 its very small perithecia on the horse dung. The fruiting is specially 

 proiuse on horse-dung, which has lain about a month, when the 

 nourishing medium is somewhat exhausted. We could often see 

 the growmg development of Sporormia, where other species of the 

 Sordariaceae and Ascobolaceae families had quite stopped growing. 

 The conditions which produce the germination of the spores are 

 quite different to those of the formerly mentioned species. One had 

 to spend much time before Avished results were obtained. For this 

 purpose various means were used: mediums were changed, also 

 their reactions, the temperature, quite fresh spores were taken, 

 such that were just scattered from the perithecia and such as had 

 lain a year. Finally the following operation only gave the wished 

 results: freshly gathered spores were put into decoctioji of slightly 

 alcalized, sterilized horse-dung and placed in a cupboard with 35^ 

 to 4:0'^ C. temperature. In 24 hours all the cells of the fourcelled 

 spores greatly swelled. Transferred into fresh decoction and placed 

 in a cupboard with 27** С temperature, they germinated in V/^ to 2 

 days. The spores of Sporomia quickly lose germination and the 

 percentage of germinated spores, which have lain after gathering 

 only two, three weeks, falls from lOO^/o of the fresh spores to SO'/o? 

 and at the same time in each spore germinate not four cells but 

 only one or two. 



Also the slow growth of the mycelium, during the culture of the 

 fungus is astonishing. Transplanted in small quantities on horse- 

 dung, or on iVaVo ^&^^ ^^'^^h decoction of horse-dung, the fungus 

 in the space of two weeks grew in circumference less than 1 c/m. 

 in diameter (the difference is especially great in comparison to 

 Sordaria), On this small space a great number of fruit-bodies form, 

 which ripen at the end of the third week of their growth. One 

 can add, that on horse-dung the fungus grew better and its fruiting
