An arthroconidial hyphomycete on living leaves of kudzu (Pueraria montana, Fabaceae), originally described by Sawada in 1959 as Ovularia puerariae, was rediscovered. This anamorph is connected to an unknown Marasmius teleomorph belonging to section Globulares, which develops on the same living leaves. Ultrastructure and LSU rDNA sequence analysis of the anamorph confirm this connection. The fungus does not have only a unique biology among agarics, comparable only to Mycena citricolor, but also has the potential for application as a control agent of kudzu. During comparison with similar anamorph genera, Illosporium graminicola was found to be a synonym for Beniowskia sphaeroidea.

Three Periconiella species were collected in Taiwan and investigated with light and scanning electron microscopy and nuc LSU rDNA analysis. A new species of Periconiella is proposed for a hyphomycete with apically branched conidiophores and relationship to Mycosphaerellaceae found on living leaves of Machilus zuihoensis and an unidentified species of Lauraceae. Two further species, Periconiella lygodii and P. perseaemacranthae, are recorded outside India for the first time and on new host species. Hadrotrichum laurinum is transferred to Passalora.
