Neocladosporium J.D.P. Bezerra, Sand.-Den., Souza-Motta & Crous, IMA Fungus 8 (1): 87 (2017).
Index Fungorum number: IF 820266; Facesoffungi number: FoF 06633, 1 morphological species (Species fungorum 2021), 1 species with molecular data.
Pathogenic on leaves. Sexual morph: Unknown. Asexual morph: Mycelium consisting of pale brown, smooth, branched, septate hyphae. Conidiophores solitary, erect, unbranched or branched above, sub cylindrical, straight to flexuous, apical septum becoming dark brown and thickened. Conidiogenous cells integrated, polyblastic, terminal and lateral, subcylindrical, smooth, brown; scars truncate, thickened and darkened. Ramoconidia medium brown, verruculose to warty, giving rise to branched chains of conidia, subcylindrical, polyblastic, brown, verruculose to warty, 0–1-septate, frequently forking close to apex; scars darkened, thickened. Intercalary conidia subcylindrical to fusoid-ellipsoidal, brown, smooth to somewhat warty. Small terminal conidia fusoid-ellipsoidal, brown, smooth; hila thickened and darkened (Adapted from Bezerra et al. 2017).
Type species: Neocladosporium leucadendri (Crous) J.D.P. Bezerra, Sandoval-Denis, C.M. Souza-Motta & Crous
Notes: Neocladosporium was introduced by Bezerra et al. (2017) with N. leucadendri as type species. Neocladosporium resembles Toxicocladosporium but can be differentiated based on the size and ornamentation of ramoconidia (verruculose to warty) and ramoconidia often forking close to the apex. Neocladosporium also resembles Cladosporium s. str., but differs in the size and ornamentation of the ramoconidia (verruculose to warty), which are often forking close to apex, dark, thick-walled conidial and conidiophore septa, with the absence of the typical coronate Cladosporium scar type. Neocladosporium differs from Graphiopsis based on the conidiophores (cladosporioid and periconioid morphs), conidiogenous loci and hila (Schubert et al. 2007a; Braun et al. 2008); Neocladosporium can also be distinguished from Rachicladosporium as the latter has an apical conidiophore rachis with inconspicuous to subconspicuous scars and unthickened, not darkened-refractive conidial hila (Crous et al. 2007); and Neocladosporium can be compared to Verrucocladosporium which has mostly an unusual conidial and hyphal ornamentation (Crous et al. 2007). Neocladosporium is a distinct and well-supported genus in Cladosporiaceae.
