Despite the growing interest in its hallucinogenic properties, the fundamental systematics of this genus remains poorly resolved due to limited taxon sampling and limited genetic characterization. This study combines a comprehensive sampling of all <i>Lanmaoa</i> species, including 21 type specimens, with whole genome sequencing of 53 specimens. A phylogeny of <i>Lanmaoa</i> is generated based upon an alignment of 1515 single-copy orthologs and recovers full statistical support at all major nodes, resolving evolutionary relationships in the genus. Phylogenomic analysis of previously unsequenced type specimens supports several taxonomic changes, including six novel combinations and the discovery of four novel species, two of which are described here-<i>Lanmaoa fallax</i>, sp. nov. and <i>Lanmaoa carbonilivor</i>, sp. nov.-resulting in a total recognition of 17 species in the genus. Genome mining of <i>Lanmaoa asiatica</i> fails to detect canonical biosynthetic genes associated with psilocybin or ibotenic acid production, suggesting the presence of a novel psychoactive compound.

This study examined how strain handling can affect in vitro growth and in planta virulence of <i>H. fraxineus</i>, with implications for maintaining culture collections for laboratory and greenhouse studies. Ten <i>H. fraxineus</i> strains were selected: seven from a strain collection and three newly isolated individuals. Growth characteristics of the strains were evaluated in vitro on malt extract agar (MEA) and ash-amended malt extract agar (AMEA). Virulence was also investigated in planta following artificial inoculations into <i>Fraxinus excelsior</i> saplings. In vitro growth rate did not correlate with virulence in planta. The strains were subsequently reisolated to investigate changes in in vitro growth and in planta virulence due to reintroduction to the host. Reintroduction to the host led to increased virulence of strains in planta, including a significant increase in necrosis growth rate following two reintroductions. There was a significant increase in necrosis growth rate following two reintroductions to the host. These observations were more distinct in newly isolated strains previously cultured on AMEA. Moreover, more strains were virulent when previously cultured on AMEA, compared with MEA. These results indicate not only that strains of <i>H. fraxineus</i> from collections can be rejuvenated, but also that the virulence of newly isolated strains can be increased. Overall, these results provide insights into the impacts of laboratory protocols on in vitro growth characteristics and in planta virulence of <i>H. fraxineus</i> strains.

The tested antidepressants had MIC values ranging from 8 to 128 μg/mL and mostly had synergistic interactions when combined with AMB. Additionally, their mechanisms of action can be related to the induction of severe oxidative stress that leads to apoptosis in fungal cells showing a synergistic effect when combined with AMB.
