Euantennaria
Euantennaria Speg., Boln Acad. nac. Cienc. Córdoba 23(3-4): 549 (1918).
Index Fungorum number: IF 808876; Facesoffungi number: FoF 06933, 9 morphological species (Species Fungorum 2022), no molecular data available.
Parasitic on pine needles. Mycelium superficial, dark, flattened. Hyphae cylindrical, straight to irregularly curved, occasionally anastomosing, septate, finely or coarsely roughened, pale brown to brown, lateral repent branches occur at right angles or at a wide angle and may be solitary or opposite. Sexual morph: Ascomata perithecial, unilocular, superficial on hyphae, scattered, subglobose, brown to dark brown, membranous, ostiolate without periphysoids, surrounded by cylindrical hyphal appendages, containing few asci. Peridium thick, dark, composed of one layer of dark brown cells of textura angularis. Pseudoparaphyses lacking. Asci 4–8-spored, bitunicate, ellipsoidal, thin-walled, sessile, with an ocular chamber. Ascospores irregularly arranged in asci, ellipsoidal, pale brown to brown, 3–7-septate, or dictyoseptate, with or without mucronate ends, rounded at the ends, slightly or not at all constricted at the septa. Asexual morph: Unknown (adapted from Hyde et al. 2013).
Type species: Euantennaria tropicicola Speg.
Notes: Euantennaria is characterised by unilocular, superficial, subglobose ascomata, ellipsoidal, thin-walled asci and ellipsoidal, pale brown to brown ascospores. Euantennaria resembles Strigopodia, but molecular data are needed to confirm whether they are congeneric. Euantennaria has two asexual morphs, antennatula-like (phragmoconidial states) and hormisciomyces-like (phialidic state) (Hughes 1974). Hughes (1974) described four euantennariaceous sooty moulds from New Zealand. The author suggested that Hormisciella rubi Bat. is a possible name of the antennatula state and Hormisciomyces prepusum Bat. & Nasc. and H. bellum Bat. & Carn. are probable names for the hormisciomyces state. However, more collections and sequence data are needed to confirm their relationships. Euantennaria differs from other genera in Euantennariaceae in having pale brown to brown ascospores. Euantennaria is currently a distinct genus in Euantennariaceae but this needs confirmation with DNA sequence data.
