Fuscosporella

The word Fuscosporella is derived from the Latin word -fusco, meaning dark and the Greek word spore meaning “seed, sowing”.^[4]

Fuscosporella was originally established as a monotypic genus for Fuscosporella pyriformis J. Yang, J. Bhat & K.D. Hyde, and it is the type genus of Fuscosporellaceae (Yang et al. 2016).^[1] Fuscosporella pyriformis is morphologically similar to Parafuscosprella moniliformis J. Yang, J. Bhat & K.D. Hyde and Parafuscosprella mucosa J. Yang, J. Bhat & K.D. Hyde, as they share characters such as uniseptate (having a single cell wall), dark brown, obvoid (egg-shaped and solid, with the narrow end at the base) to obpyriform (shaped like that of a pear, with the base at the narrower end) conidia of similar size, and hyaline (glassy/transparent), vesicular (bladder-like sac) conidiogenous cells. Parafuscosporella garethii Boonyuen, Chuaseehar. & Somrith. is significantly different from the species in its obpyramidal conidia, which are coronate at the apex with unusual conical projections (Boonyuen et al. 2016).^[5] However, molecular evidence later gave a precise classification.^[6]

3 species are accepted by Species Fungorum;^[7]

• Fuscosporella aquatica J. Yang & K.D. Hyde (2017)
• Fuscosporella atrobrunnea L.L. Liu, J. Yang & Z.Y. Liu (2023)
• Fuscosporella pyriformis Jing Yang, Bhat & K.D. Hyde (2016)

Fuscosporella xingyiensis was published in 2022, but not yet fully accepted.^[8]

It has been only found in a few places worldwide, such as; off the coast of south America, in central Asia, in Thailand and China.^[9][10]

Species in Fuscosporella and Mucispora are reported from freshwater habitats in Thailand and China,^[1][11][12]
