cosias in statu typico esse ascigeras! Sic successive omnia Pyrenomycetum genera 
absque ascis ad ascigeros migrant vel, ut Spheropsides, status spermogoniis in- 
structi censendi." 
Although I have seen asci in Discosia alnea, Fr., I have not yet observed them 
in D. Artocreas, Fr. In my former paper I conjectured that the sporidia of the 
latter species were formed in asci, which deliquesce at an early stage. This is by no 
means improbable, although the sporidia of D. Artocreas are certainly sometimes 
borne singly upon sterigmata. In the perfect state of Spheria pulicaris, Fr., 
the sporidia are produced in asci, whilst in the so-called Hendersonia arcus, B. & Br., 
which I believe to be only the stylosporous condition of S. pulicaris, similar sporidia 
are borne upon sterigmata. In the stylosporous condition of D. Artocreas, the 
second filiform appendage is not visible whilst the stylospores are attached to the 
hymenium, although the setum at the distal end is perfect,
