Globoramichloridium Y. Marín & Crous, in Marin-Felix et al., Stud. Mycol. 94: 81 (2019).

Index Fungorum number: IF 829622; Facesoffungi number: FoF 06643, 2 morphological species (Species Fungorum 2022), 2 species with molecular data.

Saprobic or pathogenic on host. Sexual morph: Unknown. Asexual morph: In culture submerged hyphae smooth, thin-walled, hyaline with thin septa, aerial hyphae coarsely verrucose, olivaceous-green, rather thick-walled, with thin septa. Conidiophores arising vertically from creeping hyphae at right angles, straight, unbranched, thick-walled, smooth, dark brown, with up to 10 thin septa, often with inflated basal cells. Conidiogenous cells terminally integrated, smooth, dark brown, sympodially proliferating, rachis straight or flexuose, geniculate or nodose, subhyaline; scars thickened and darkened, clustered at nodes. Microcyclic conidiation observed in culture. Conidia solitary, (0–)1- septate, not constricted at the septum, sub hyaline to pale brown, smooth or coarsely verrucose, rather thin-walled, broadly ellipsoidal to globose with truncate base; hilum conspicuous, slightly darkened, not thickened, about 1 µm diam. (adapted from Arzanlou et al. 2007).


Type species: Globoramichloridium indicum (Subram) Y. Marín & Crous


Notes: Globoramichloridium differs from Ramichloridium in having broadly ellipsoidal to globose, typicallyuniseptate, smooth-walled or slightly verrucose conidia while Ramichloridium is characterised by clavate or oblong to ellipsoid or obovate to obconical, aseptate, smooth-walled to finely verrucose conidia. Molecular markers available for Globoramichloridium are LSU and ITS.
