Overview

Taxonomic and ecological investigation reveals two novel Lulworthiales fungal genera in seagrass roots and saline soils, highlighting the ecological plasticity of marine-associated lineages.

Key Points

  • To identify and classify novel root-associated and soil-dwelling fungi isolated from osmotically stressed marine and terrestrial environments within the order Lulworthiales.
  • Cultured fungal isolates from roots of the seagrass Thalassodendron ciliatum in Mauritius and saline inland soils in Czechia.
  • Performed morphological evaluations and multi-locus phylogenetic analyses utilizing three rDNA markers to establish taxonomic positions.
  • Queried published environmental ITS rDNA metabarcoding records within the GlobalFungi database to map global geographic and biome distributions.
  • Established two new lineages within Lulworthiales: Thalassodendromyces purpureus gen. et sp. nov., forming monilioid hyphae, and Halomyrma pluriseptata gen. et sp. nov., forming multicellular conidia.
  • Metabarcoding data showed H. pluriseptata is widely distributed across temperate, subtropical, and tropical aquatic biomes, while T. purpureus yielded zero GlobalFungi detections.
  • Confirmed the occurrence of Lulworthiales lineages in non-marine saline inland soils, challenging the strict marine exclusivity of the fungal order.
