They were found as mycoparasites on: <i>Ophiocordyceps</i> infecting flies (<i>Diptera</i>) for <i>Niveomyces albus</i>; ants (<i>Hymenoptera</i>) for <i>N. formicidarum</i>; and leafhoppers (<i>Hemiptera</i>) for <i>N. hirsutellae</i> and <i>N. multisynnematus</i>. A new genus, <i>Pseudoniveomyces</i> with two species: <i>Pseudoniveo. blattae</i> (type species), parasitic on <i>Ophiocordyceps</i> infecting cockroaches, and <i>Pseudoniveo. arachnovorum</i>, found on a spider egg sac, are also described. These fungi share a common feature which is a sporothrix-like asexual morph. Based on our molecular data, <i>Sporothrix insectorum</i> is shown to be affiliated to the genus <i>Niveomyces</i>, and thus a new combination <i>N. insectorum comb. nov</i>. is proposed. <i>Niveomyces coronatus</i>, <i>N. formicidarum</i> and <i>N. insectorum</i> formed the <i>N. coronatus</i> species complex found on ant-pathogenic <i>Ophiocordyceps</i> from different continents. <i>Pseudoniveomyces</i> species are distinguished from <i>Niveomyces</i> spp. based on the presence of fusoid macroconidia in culture and a red pigment diffused in the medium, resembling to <i>Gibellula</i> and <i>Hevansia</i>. The molecular phylogenetic analyses also confirmed its generic status. The host/substrates associated with the genera within <i>Cordycipitaceae</i> were mapped onto the phylogeny to demonstrate that mycoparasitism also evolved independently multiple times in this family. <b>Citation:</b> Kobmoo N, Tasanathai K, Araújo JPM, Noisripoom W, Thanakitpipattana D, Mongkolsamrit S, Himaman W, Houbraken J, Luangsa-ard JJ (2023).

However, there is a poorly studied group, the <i>Rhipidiales</i>, which placement amongst the crown oomycetes is ambiguous. It accommodates several taxa with a sophisticated vegetative and reproductive cycle, as well as structural organisation, that is arguably the most complex in the oomycete lineage. Despite the remarkable morphological complexity and their notable perseverance in the face of faster-growing saprotrophic oomycetes and fungi, the knowledge on <i>Rhipidiales</i> is limited to date, as the most complex members are not easily cultured, even by targeted approaches. This also leads to inadequate sequence data for the order, which was sourced from only the two least complex out of seven introduced genera, <i>i.e.</i> <i>Sapromyces</i> and <i>Salispina</i>. In the present study, <i>ex-situ</i> baiting was done using various fruit substrates, and naturally-shed twigs or fruits acquired from water bodies were examined. As a result of these efforts, the species <i>Rhipidium</i> <i>interruptum</i> was obtained and gross cultivation was accomplished using poplar (<i>Populus nigra</i>) twigs as substrate, which allowed further documentation of both asexual and sexual reproduction.
