compressed and confluent sporangia; they are similar to those de- 
scribed and figured in this Journal* from specimens supplied by 
Dr. Jahn from a ba in the University Gardens, Berlin, and from

an area 15 mm. across. m Brazil, referred 
to above, there is also an ethalium} ‘of the suite pes as that 
described from Japan, and nearly equalling itin size; the statement 
in our former paper that P. gyrosum formed only small ethalia, 
though true with regard to the gatherings hitherto sect in 
Germany, is thus shown to be not of universal applica ioe,
