The genus Speiropsis, ereted by Tubaki (1958). The species shown conidiophores macronematous, mononematous, solitary, erect, straight, simple, septate, smooth, with consecutive short branches at the apex, pale brown. Polyblastic, sympodial conidiogenic cells emerge from the top of the conidiophore forming chains of up to nine cells, pinned, denticulated at the apex, from pale brown to subhialines. Conidia composed of 5-7 cells connected by an isthmus forming a hyaline chain, the cells at the ends are conical and the intermediates cylindrical (Kuthubutheen & Nawawi, 1987).

The species presents unknown distribution and is found in tropical and subtropical regions, associated with leaf litter and submerged substrates. It has great importance in the decomposition of organic matter, so it is necessary more studies in these and other regions, as well as to study conservation actions in preserved areas in order to preserve this and other species to ensure biodiversity.

Distribution: in subtropical and tropical climate regions

So far, there are eight species for the genus. The species is found associated in leaf and petiole and submerged leaf, records in Mexico (Heredia; Arias; Reyes, 2000), Cuba (Castañeda-Ruiz et al., 1998) and Hong Kong (Lu et al., 2000).

Leaf litter and and submerged leaf. Terrestrial and fresh water.

None

In the world, there are no records of the species in Europe, Oceania, Africa and the Poles. In Brazil, there is no occurrences in the midwest and in coastal lands, mangroves and other ecosystems.
