of inoculations 120 caterpillars were chosen; of — 100 were inocu- 
lated with fresh ordinary spores, while the rest were placed aside for 
a control-experiment. Of the first 100 inoculated, 81 showed the disease

Dr. Brefeld holds that these resting-spores arise ECHR ; by 
means of them, of course, the fungus passes through the winter. He 
refers to the resting state of E. radicans Fresenius’ E. s oe sperma ; 
moreover, the genus Zarichium of Cohn must disappear altogether ; 
indeed he thinks it possible that Zarichium se rach erode ay

resting-spores as an additional proof of asexuality of Basidiomycetes.

in two new species (£. curvispora and E. ovispora) These zy gospores 
are produced in the manner that Brefeld himself er gre in the

outgrowths of two co onjugating cells. nw akaeaky, moreover,
