Neoplatysporoides Crous & M.J. Wingf., Persoonia 34: 197 (2015)
Saprobic on leaf. Sexual morph: Ascomata immersed in a brown stroma, becoming erumpent, breaking through the host surface, aggregated in clusters, with a central, non-papillate ostiole. Peridium comprising 6–10 layers of brown textura angularis. Pseudoparaphyses hyphal-like, intermingled among asci, hyaline, smooth, septate, anastomosing. Asci fasciculate, stipitate, hyaline, smooth, sub cylindrical, bitunicate with ocular chamber, containing 8 ascospores. Ascospores fusoid-ellipsoid, brown, verruculose with obtuse ends, developing 3 transverse and 1–2 vertical septa, encased in a mucoid sheath. Asexual morph: Conidiomata unilocular, separate, globose, immersed, brown, opening via central ostiole, exuding a brown conidial mass; wall of 3–6 layers of brown textura angularis. Conidiophores reduced to conidiogenous cells. Conidiogenous cells lining the inner cavity, hyaline, smooth, ampulliform to doliiform, with prominent periclinal thickening at apex, or with tightly aggregated percurrent proliferations at apex. Conidia solitary, golden brown, sub cylindrical to ellipsoid, straight to curved, 0–1-septate, constricted at median septum, apex obtuse, base truncate, with marginal frill, and longitudinal striations (Adapted from Crous and Wingf 2015).
Type species: Neoplatysporoides aloicola Crous & M.J. Wingf.
Notes: Neoplatysporoides was introduced by Crous and Wingf. (2015) with N. aloicola as type species. Neoplatysporoides resembles Platysporoides in having muriform septate ascospores surrounded by mucoid sheaths (Shoemaker and Babcock 1992) but differs in having a thick-walled immersed pseudothecia, and the noticeable coelomycetous asexual morph, which occurs with the ascomata on the same host substrate. Neoplatysporoides is associated with tip dieback of Aloe ferox while Platysporoides occurs on leaf litter. Neoplatysporoides is also similar to Austropleospora but the latter lacks a pseudostroma, has papillate ascomata, and smooth ascospores (Morin et al. 2010). Phylogenetically, Neoplatysporoides is a distinct genus in Libertasomycetaceae.
