Plurispermiopsis

Plurispermiopsis Pereira-Carv., Inácio & Dianese, in Pereira-Carvalho, Inácio & Dianese, Mycologia 102(5): 1163 (2010)

Index Fungorum number: IF 515215; Facesoffungi number: FoF xx, 1 morphological species (Species Fungorum 2021), molecular data unavailable.

Saprobic on host. Sexual morph: Unknown. Asexual morph: Colonies effuse, epiphyllous, superficial. Mycelium superficial, pale brown. Hyphae septate, branched, pale brown; hyphal cells cylindrical or monilioid. Ascomata ostiolate, globose or ovoid, superficial, unilocular, smooth. Peridium with texture ranging from globose to angular. Asci broadly clavate, subglobose or ovoid, bitunicate, aparaphysate, approximately 64- spored. Ascospores hyaline, elliptical to fusoid, 1–2-septate but seldom threeseptate, short-appendiculate (Adapted from Pereira-Carv et al. 2010).

 

Type species: Plurispermiopsis cerradensis Pereira-Carv., Inácio & Dianese

 

Notes: Plurispermiopsis was introduced by Pereira-Carvalho et al. (2010) with P. cerradensis as type species. Plurispermiopsis resembles members of Capnodiaceae in having cylindrical hyphal cells with constrictions at the septa hence displaying a moniloid aspect, ostiolate ascomata and absence of a hamathaecium. Plurispermiopsis is unique and differs from other members of Capnodiaceae in having different shape of ascoma, lack of mycelium with a mucous layer. Also, none of the genera in Capnodiaceae are characterized with glabrous ascomata containing asci with up to 64 hyaline, short-appendiculate, 1–2– (rarely 3)- septate ascospores. The taxonomic placement of Plurispermiopsis is still uncertain and is currently placed in Capnodiales genera incertae sedis.
