Note The same description (with the word “spora” added in 
parenthesis after spermatia) is given on the label in Thiimen, Mycoth. 
univ. N. 1295. The date of the latter, however, is 1879.

Through inadvertancy an incorrect transcription was made 
for the label for No. 157, which is therefore to be discarded and 
the following label used instead.
