Neogamszarella W. H. Chen, Y. F. Han & J. D. Liang gen. nov.

Etymology.

Named after its morphological similarity to the genus Gamszarella.

Type species.

Neogamszarella antillana (R. F. Castañeda & G. R. W. Arnold) W. H. Chen, Y. F. Han & J. D. Liang (Basionym = Verticillium antillanum R. F. Castañeda & G. R. W. Arnold , Feddes Repert. Spec. Nov. Regni Veg. 98 (7–8): 411, 1987).

Description.

Colonies on PDA, white, with cream-colored reverse, without diffusing pigment into the agar. Conidiogenous cells developing on prostrate hyphae, single or up to 6 in verticils, subulate. Conidia solitary and of two types. Octahedral crystals present.

Host.

Agaric (Hymenomycetes).

Sexual morph.

Unknown.

Remarks.

The genus Gamszarella was established with the type species G. buffelskloofina and two species, G. antillana and G. magnispora (Z. F. Zhang & L. Cai) Crous based on the phylogenetic analysis ( Crous et al. 2023). Khonsanit et al. (2024) introduced a new genus Corpulentispora Khons., Thanakitp. & Luangsa-ard to accommodate Gamszarella magnispora based on the phylogenetic analysis and morphological characteristics. The morphological characteristics of Gamszarella buffelskloofina are conidiogenous cells subcylindrical with apical taper, terminating in a cluster of denticles and only one type of subcylindrical conidia ( Crous et al. 2023). While the morphological characteristics of Gamszarella antillana are conidiogenous cells absent of denticles and produce two types of fusoid conidia, macroconidia and microconidia. G. antillana do not fit with the genus Gamszarella . Thus, a new genus is proposed to accommodate species Gamszarella antillana .
