According to F uckel, Sporodum conopleoides, Sieh is the 
conidial form of this species. This suggestion however turns on 
the frequent contiguity of the two forms, and remains to be 
corroborated or otherwise, by pure cultures.

stout, dark brown, asperate, angularly bent and giving off stout,

a large dense tuft; hairs on the body of the perithecium dark

According to Zopf, the spores Of this species on germination 
form chains of minute globose conidia produced at the tips of short 
lateral branches. These chains collapse and form a spherical head 
involved in mucus, which remains attached for some time to the tip 
of the branch,
