words **basidiis uncinatis.’ When the contents of a crushed 
walking-stick. Saccardo considered these to be the sporophores 
ea faa although how spores could legitimately be borne on 
the down-turned ends of such supports he did not explain. Other 
eat ad have described them as a second kind of spore, 
exactly similar to those ied to the genus Phlyctaena, It 
seems probable that both explanations are correct; that is to say, 
there is in some species of Phomopsis, if not in all, a second 
filiform kind of spore, borne on sporophores, which are in general 
shorter than those which bear the fusoid spores, but also the long 
acicular sporophores of the latter can break away from the 
hymenium, and then become more curved than when in situ, or 
even hooked. Diedicke called the typical fusoid spores the 
A-spores, and the long filiform ones the B-spores. Von Héhne 
separated those few species in which both forms of spore were 
known to occur into the genus Myzolibertella, but it is better 
to consider these as merely a part of Phomopsis. When the B- 
spores occur, a section shows them in serried ranks, standing more 
or less para rallel and erect on their sporophores ; when only a few 
filiform structures are seen scattered among the fusoid spores, 
they are usually nothing but the transformed sporophores.
