Index Fungorum, Facesoffungi, MycoBank, GenBank, Fig 1
Classification: Chaetosphaeriaceae, Chaetosphaeriales, Sordariomycetidae, Sordariomycetes, Pezizomycotina, Ascomycota, Fungi
Etymology: Refers to its similarity to Sporoschisma in brown, cylindrical and multiseptate conidia.
Diagnosis: Conidiophores cylindrical, septate. Conidigenous cells monophialidic, terminal, cylindrical; collarette broadly funnel-shaped. Conidia cylindrical, septate, brown.
Colonies superficial, effuse, black, hairy to setose, composed of conidiophores and capitate hyphae arising from small stromata. Teleomorph: Unknown. Anamorph: Capitate hyphae present, erect, simple, sterile, brown, septate, with an apical swelling and percurrent proliferations. Conidiophores subcylindrical, erect, single or in small cluster together with capitate hyphae, septate, dark brown to blackish, terminating in a conidiogenous cell. Conidiogenous cells integrated, terminate, monophialidic, brown to dark brown, cylindrical, with short collarettes with wider opening at the apex. Conidia ellipsoidal, oblong, ends rounded, 3-septate, central cells brown to dark brown, end cells pale brown to brown, base with a distinct scar.
Ecology/Substrate/Host: Saprobe on dead material of plants.
Geographical distribution: China.
Notes: This unique fungus on decaying leaves of palm resembles Fusichalara S. Hughes & Nag Raj, Sporoschisma Berk. & Broome and Sporoschismopsis Hol.-Jech., but differs from them by the conidiogenesis. In Fusichalara, Sporoschisma and Sporoschismopsis, the conidiogenous cells are composed of distinctly differentiated venter and collarette, where the conidiogenous loci deeply sitting at the base of long collarettes. In Monosporoschisma elegans, the conidiogenous cells have typical phialides with inconspicuous collarettes and only very small part of the conidia sitting within the collarettes. In addition, Fusichalara and Sporoschismopsis are lacking capitate hyphae (Holubová-Jechová and Hennebert 1972; Holubová-Jechová 1973a, b; Hughes and Kendrick 1963; Nag Raj and Kendrick 1975; Seifert et al. 2011).
