Assessment Notes

Taxonomic notes

Menisporopsis S. Hughes was erected by Hughes (1952) to accommodate M. theobromae S. Hughes. Liu et al. (2016) contributed a detailed description of M. theobromae with DNA sequence data and phylogeny for the first time for this genus.  Keys to the Menisporopsis species were supplied by Tsui et al. (1999) and Castañeda-Ruiz et al. (2001). Setae septate, straight or slightly flexible, simple, smooth, dark brown at the base and pale brown at the apex. Conidiomata sinnematous, erect, straight or slightly flexible, dark brown at the base to brown towards the apex. Conidiogenic cells monofialidic, integrated, cylindrical, smooth.  Conidia solitary, 0-septate, lunate, viscous mass aggregates, hyaline, with a setula at each end (Cruz et al., 2014).

Why suggested for a Global Red List Assessment?

Menisporopsis theobromae is widely distributed in Brazil. Around the world it has been reported frequently in tropical and subtropical leaf litter. Studies (Ruanglek et al., 2007)) indicate biotechnological potential.

Geographic range

In tropical, subtropical and temperate climate regions

Population and Trends

There are 13 species for the genus Menisporopsis. M. theobromae is associated with plant decomposition, especially leaf litter, and has been recorded in Mexico (Heredia-Abarca, 1994), Japan (Matsushima, 1980), Cuba (Delgado-Rodriguez et al., 2002), Venezuela (Castañeda Ruiz et al. 2001), among others.

Population Trend: Uncertain

Research needed

There has been no report of the species in North America and Europe. In Brazil, despite having a wide distribution, there is no record in coastal tablelands, dunes and mangroves. The biotechnological aspects of this species can also be further studied with specimens isolated from different biomes.
