SUMMARY
The conidial stage of a fungus of common occurrence on the foliage of honey locust has been known as Melasmia hypophylla. Its fructification is an acervulus and not a pycnidium, and it belongs in the form genus Gloeosporiutn.
The perithecial stage, described as Linospora Gleditsiae develops on diseased leaves that have overwintered. Evidence of genetic connection of the two stages is based upon the development of the conidial stage on leaves that were inoculated, using leaves bearing perithecia as inoculum. Attempts to grow Linospora Gleditsiae in culture, either from ascospores or from conidia, have been unsuccessful.
It would seem that the genus Linospora, although in the Clypeosphaermceae, should better be placed nearer members of the Diaporthaceae.
