Amphilogia Gryzenh.et al., Taxon 54(4): 1017 (2005a)
Index Fungorum number: IF510065; 2 morphological species (Species Fungorum 2020), 1 species with sequence data.
Saprobic on woody bark. Sexual morph: Ascostromata orange, erumpent, slightly immersed to superficial, stromatic tissue well-developed, pulvinate with papillate to long orange perithecial necks, perithecia diatrypoid. Asci 8-spored, unitunicate, fusoid. Ascospores hyaline, fusoid to ellipsoid, containing one to three irregularly spaced septa. Asexual morph: Conidiomata orange, separate or on top of the ascostromata, also evident occasionally as locules inside ascostroma, superficial, conical to pyriform to fluted, unilocular. Conidiophores hyaline with phialidic, irregular branching, determinate conidiogenous cells that occur apically or laterally on branches beneath a septum. Conidia hyaline, non-septate, oblong to slightly curved, of variable size.
Type species: Amphilogia gyrosa (Berk. & Broome) Gryzenh. et al., in Gryzenhout et al., Taxon 54(4): 1017 (2005a).
Notes – Amphilogia was introduced to accommodate Cryphonectria gyrosa (CMW 10471/CRY 1551) based on its morphological distinctness such as superficial conical conidiomata, conidia of variable size and ascospores with one to three septa (Gryzenhout et al. 2005). The second species Amphilogia major, accommodated in this genus, was reported from New Zealand (Gryzenhout et al. 2005).
