Classification: Paracladophialophoraceae, Chaetothyriales, Chaetothyriomycetidae, Eurotiomycetes, Pezizomycotina, Ascomycota, Fungi

Pathogenic on leaves. Mycelium comprising branched, pale brown, septate, smooth-walled hyphae. Sexual morph: Undetermined. Asexual morph: hyphomycetous. Conidiophores macronematous, solitary, erect, grey- brown, straight or curved, septate, apical apparatus tuft-like due to extremely long conidial chains. Conidiogenous cells terminal and lateral, mono- and polyblastic, proliferating sympodially, subcylindrical, pale brown, smooth-walled. Conidia ellipsoid to fusoid-ellipsoid, aseptate, pale brown, smooth-walled, guttulate, in long branched chains, ramoconidia subcylindrical, septate.

Notes: Paracladophialophora Crous was introduced by Crous et al. (2016) with the yeastlike species P. carceris Crous & Roets, isolated from the living leaves of Aloe sp. (Asphodelaceae). This genus is characterized by mono- and polyblastic, subcylindrical conidiogenous cells and ellipsoid to fusoid-ellipsoid, aseptate conidia in long branched chains (Crous et al. 2016). Paracladophialophora resembles Cladophialophora, because some Cladophialophora species have also been found associated with living plants (Crous et al. 2007, 2013, de Hoog et al. 2007, Badali et al. 2011, Park & Shin 2011, Feng et al. 2014), while Cladophialophora has flask-shaped or funnelshaped phialides, collarettes occasionally present, and hyaline, subspherical, aseptate phialoconidia. Phylogenetically, Paracladophialophora constitutes a distinct clade in Chaethytiales.

Type species: Paracladophialophora carceris Crous & Roets, Persoonia 37: 299 (2016).

Other accepted species: Species Fungorum – search Paracladophialophora.
