Abstract: | The Clypeosphaeriaceae is retained to include sixteen genera.Apioclypea, Ceratostomella, Clypeophysalospora, Clypeosphaeria, Crassoascus, Jobellisia, Oxydothis andUrosporella are described and illustrated, whileApiorhynchostoma, Brunneiapiospora, Capsulospora, Duradens, Frondispora, Leiosphaerella, Pseudovalsaria andStereosphaeria are discussed. Genera in the Clypeosphaeriaceae are distinguished from those in, the Amphisphaeriaceae (sensu stricto). Their
ascomata are immersed and typically clypeate. Asci are 8-spored, unitunicate, cylindrical, with a J+ or J−, apical ring. Ascospores
are usually ellipsoidal or cylindrical, brown or hyaline, unicellular, pseudoseptase or septate, at times with appendages
or germ pores. The Clypeosphaeriaceae is considered a member of the Amphisphaeriales and the differences between the Clypeosphaeriaceae
and Amphisphaeriaceae are discussed. We are unsure if the Clypeosphaeriaceae as we define it is monophyletic. |
