A new species ofJusticia sect.Ansellia (Acanthaceae) from Tanzania

Paxillibracon inornatus sp.n. from Tanzania is described, illustrated and distinguished from Paxillibracon tessmanni (Szépligeti), the only other known species of the genus. The scapus, antennal sockets, features of the venation and metasomal sculpture of P. inornatus sp.n. reinforce the earlier interpretation that Paxillibracon is derived from close to the base of the Atanycolus Foerster group of genera.

Three new species of Chassalia (Rubiaceae) from the Eastern Arc Mts, Tanzania

Chassalia christineae, sp. nov., and C.bonifacei, sp. nov., from the Nguru Mts, and C.lukwangulensis, sp. nov., from the Uluguru Mts, are described and illustrated. All three species are undershrubs of montane forest.     

A new species ofConiochaetidium from soil

A new species ofConiochaetidium isolated from soil of Iraq is described. The speciesC. nuciforme differs fromC. savoryi in the shape and size of the ascospores. A key to differentiate the accepted species of the genus is reported.     

A new species ofScopulariopsis from soil

A new species ofScopularoipsis described from soil is characterized by the conidiophores, branches, and sporogenous cells being distinctly swollen. The conidia have a well-marked germ slit running more or less longitudinally down the spore. TheScopulariopsis state ofMicroascus doguetii is re-examined and evidence is presented which indicates that the striations on the walls of the spores are germ slits.     

A new species of Arthothelium from Norway

Arthothelium norvegicum Coppins & Tonsb. sp. nov. is most closely related to A. ruanum (Massal.) Zwackh, but is morphologically, anatomically and ecologically distinct. It is known from one locality in Central Norway.
