Pleurothecium is a genus of terrestrial and freshwater fungus in the family Pleurotheciaceae.
History
Fernández et al. (1999) established
Carpoligna with the sexual stage of
Carpoligna pleurothecii as the type species and sporulated asexual stage from culture, which was physically linked to
Pleurothecium recurvatum.
Réblová et al. (2016) proposed to adopt
Pleurothecium over
Carpoligna (Art. F.8.1, Shenzhen code).
Thus,
Carpoligna pleurothecii was then regarded as a synonym to
Pleurothecium recurvatum.
Based on morphological and molecular data, species Pleurotheciella was found to be closely related to the genera Pleurothecium and Sterigmatobotrys in 2012.
A key to the various species of Pleurothecium was provided by Monteiro et al. (2016).
Description
Pleurothecium species are characterized by astromatic, semi-immersed to superficial, dark brown, venter subglobose to conical perithecia, with a papilla or short beak. They are sometimes lying toward the host, with or without
setae (bristles), sparse or abundant, septate (having septa; divided by partitions), hyaline (transparent) paraphyses (sterile upward-growing, basally-attached hypha), unitunicate (single walled), cylindrical-clavate (club) shaped. They have a short-stipitate
Ascus with a distinct, J-apical ring and
hyaline (glass-like), 3-septate, ellipsoidal to fusiform ascospores without mucilaginous sheath or appendages. The asexual morphs have distinct brown
conidiophores (conidia, which are borne on specialized stalks) and polyblastic, sympodially denticulate (having teeth-like structures) conidiogenous cells. It also has solitary, unicellular or septate, cylindrical, ellipsoidal, fusiform or clavate
conidia, straight or slightly curved (Wu & Zhang 2009,
Réblová et al. 2012,
Luo et al. 2018,
).
Distribution and habitats
It has a scattered distribution, including places such as China and Thailand,
