Amanita marinae (Basidiomycota), a new species from the mid-west region of Western Australia
DAVISON, E.M. AND GIUSTINIANO, D., Nuytsia 34: 111–123 (2023)
Amanita marinae E.M.Davison & Giustiniano from sect. Validae (Fr.) Quél. is described from Kwongan vegetation in the Lesueur Sandplain of the mid-west region of Western Australia. It is distinguished by a white to ivory pileus; white to pale vinaceous buff universal veil; a white, membranous, flaring partial veil; amyloid elongate spores; and absence of clamp connections. Its affinities with other members of sect. Validae are unclear as phylogenetic analyses of nuLSU and tef-1 sequences show affinities with northern hemisphere species, whilst comparison of ITS sequences shows affinities with an undescribed species from New Zealand. Variability in the ITS region between cloned haplotypes of A. marinae was less than 1% — comparable with haplotype divergence previously observed for other sect. Validae.
Taxonomic resolution of infraspecific taxa in Lambertia orbifolia (Proteaceae) using molecular and morphological evidence
WEGE, J.A., MONKS, L.T., WEBB, A.D., BINKS, R.M. AND COATES, D.J., Nuytsia 34: 125–137 (2023)
The taxonomy of three informally-named, conservation-listed subspecies of Lambertia orbifolia C.A.Gardner was assessed using genotypic data generated from microsatellites in concert with morphological information. They were found to warrant formal taxonomic recognition and individualised conservation management. Lambertia orbifolia subsp. vespera A.D.Webb, L.Monks & Wege, an Endangered taxon from the Scott River Plains, and L. orbifolia subsp. pecuniosa A.D.Webb, L.Monks & Wege, a recently discovered and apparently rare taxon from south-west of Bowelling, are newly described and comparative data are provided for L. orbifolia subsp. orbifolia, a Critically Endangered taxon found near Narrikup. A revised description of L. orbifolia is also provided.
