Assessment Notes

Taxonomic notes

The genus Wiesneriomyces was erected by Koorders (1907), with W. javanicus as the type species. In 1984, Kirk, analised the holotype of Volulellaria laurina Tassi and showed this provided na earlier name for W. javanicus and hence proposed the new combination W. laurinus (Tassi) P.M. Kirk. The conidioma of Wiesneriomyces laurinus is a prominent sporodochium with conidiophores and setae arising from its basal, pseudoparenchymatous stalk. Conidiophores macronematous, cylindrical, erect, branched at the apex, straight or flexuous, smooth, septate, hyaline. Conidiogenous cells polyblastic, discrete, determinate, clavate or cylindrical, usually with two or three denticles. Conidia formed in acropetal chains of 6-8 cells, tapering at both ends, falcate, connected by narrow isthmi, hyaline (Kirk, 1984; Suetrong et al., 2014).


Why suggested for a Global Red List Assessment?

The study of conidial fungi in differs environments in around in the world, can assist in expanding the knowledge of the diversity of existing fungi, as well as the factors that interfere this community, so that conservation measures and further research, not only in the ecological sphere but also in biotechnology, can be expanded.


Geographic range

Distribution: Cosmopolitan


Population and Trends

There are four species for the genus Wiesneriomyces. Despite the W. laurinus species is considered cosmopolitan, it occurs more frequently in tropical areas, in many different kinds o leaf litter. This species has been isolated in Cuba (Delgado-Rodriguez et al., 2002), Venezuela (Castaneda-Ruiz et al., 2003), Mexico (Begerow et al., 2000), Myanmar (Thaung, 2008), USSR (Melnik, 1992) and others.

Research needed

Carry out studies of conidial fungi in various biomes and regions of the world, and in Brazil, in order to know the enzymatic properties of this group based on diversity studies, for applications in ecological, biotechnological, medical and other research.

Use and Trade

In addition to morphological analyses, molecular analyses based on ribosomal gene sequences have helped to elucidate the relationships between fungi. However, sequences in multiple genes are often necessary to provide accurate phylogenetic positions for many rates. Since Phalangispora and Setosynnema have some morphological characteristics common to W. laurinus, such as the same sporodochia some dark setae (Guo et al., 2019).
The Wiesneriomyces clade is elevated to a higher taxonomic rank, the family Wiesneriomycetaceae, based on cultural, morphological and multi-gene phylogenetic evidence (Suetrong et al., 2014).
