Circumscription and infrageneric classification of Kunzea is evaluated after phylogenetic analyses of nrDNA ITS and ETS sequences. Kunzea is monophyletic if the K. ericoides complex and the monotypic Angasomyrtus are included. The genus can be divided into western Australian, eastern Australian, and eastern Australian plus New Zealand clades. Angasomyrtus has greater affinity with the eastern Kunzea species, despite its western Australian endemic status. A new infrageneric classification is proposed, recognising four subgenera, with a further division into sections within two of these. A new combination in Kunzea is made for Angasomyrtus.

Two species are removed from the genus Poa in Australia on the basis of morphology and DNA and placed in new genera. One is placed in Saxipoa Soreng, L.J.Gillespie & S.W.L.Jacobs – type: S. saxicola (R.Br.) Soreng, L.J.Gillespie & S.W.L.Jacobs; and one is placed in Sylvipoa Soreng, L.J.Gillespie & S.W.L.Jacobs – type: S. queenslandica (C.E.Hubb.) Soreng, L.J.Gillespie & S.W.L.Jacobs. An infrageneric classification of Poa is proposed that places all 41 indigenous Australian species in P. subg. Poa supersect. Homalopoa sect. Brizoides. Thirty-three of these species, plus six species of New Zealand Poa, are placed in a new P. subsect. Australopoa Soreng, L.J.Gillespie & S.W.L.Jacobs. Two species are placed in P. subsect. Austrofestuca (Tzvelev) Soreng, L.J.Gillespie & S.W.L.Jacobs, one in P. subsect. Brizoides (Pilg. ex Potztal) Soreng, L.J.Gillespie & S.W.L.Jacobs, and one in P. subsect. Neuropoa (Clayton) Soreng, L.J.Gillespie & S.W.L.Jacobs.

Cortinarius section Xenosmatae, originally based on solely morphological characters, was subsequently shown to contain phylogenetically distantly related species. The type species C. xenosma is a singleton, and this study aims to revise the other members of the section using combined molecular (nrDNA ITS and LSU) and morphological data. Based on phylogenetic analyses using RAxML, PhyML and Bayesian Inference and additional morphological features one new species (C. paraxenosma) and one new section (sect. Olorinati) are proposed. Furthermore sect. Carbonelli is extended and emended to include two former members of sect. Xenosmatae. A key to the species in New Zealand with xenosmatoid morphology is provided.

The family Stictidaceae (Ostropales, Ascomycota) contains both lichenized and non-lichenized fungi. Here, we test if Conotrema (lichenized) and Stictis (non-lichenized) as currently delimited are distinct monophyletic genera, by parsimony and parsimony jackknifing analyses of combined nuclear rDNA (ITS and partial LSU rDNA) and mitochondrial SSU rDNA sequence data matrices. The study includes four species of Stictis, three species of Conotrema, and representatives of the related Schizoxylon (lichenized), Odontotrema, Carestiella (at least sometimes associated with algae), Cryptodiscus and Thelotrema (lichenized). In all analyses, the Conotrema species were nested within Stictis with high support. Thus, we conclude that Conotrema are only lichenized representatives of Stictis. The type species of the two generic names, C. urceolatum and S. radiata, are sister taxa in our analyses. Furthermore, the analysis gave no support for the present infrageneric classification of Stictis. Carestiella socia (the type of Carestiella) and the two representatives of Schizoxylon studied were also nested within Stictis s. lat. The Odontotremataceae is the sister group to the Stictidaceae, and Cryptodiscus foveolaris groups with Thelotrema rather than with the Stictidaceae. We conclude that lichenization in the Stictidaceae does not characterize natural groups, and that Conotrema should be considered a synonym to Stictis, as predicted by anatomical characteristics. The new combinations Stictis urceolatum and Stictis populorum are made.

Pycnolejeunea glauca, originally described by Stephani based on a collection in New Zealand by William Colenso, was placed by Grolle into the synonymy of the paleotropical species Cheilolejeunea intertexta with a type from Micronesia. In this study, we generated DNA sequences from a recently-collected sample of P. glauca and compared them with published sequences of C. intertexta from China. Pycnolejeunea glauca was recovered in the phylogenetic analyses as sister to C. nipponica, whereas C. intertexta grouped in another clade with C. vittata and C. streimannii. The analysis justifies the reinstatement of P. glauca as the new combination Cheilolejeunea glauca, a New Zealand endemic. Descriptions and illustrations are provided of key features of this species together with data on its position in the phylogeny of the genus.

Resinicolous fungi constitute a heterogeneous assemblage of fungi that live on fresh and solidified plant resins. The genus Sarea includes, according to current knowledge, two species, S. resinae and S. difformis. In contrast to other resinicolous discomycetes, which are placed in genera also including non-resinicolous species, Sarea species only ever fruit on resin. The taxonomic classification of Sarea has proven to be difficult and currently the genus, provisionally and based only on morphological features, has been assigned to the Trapeliales (Lecanoromycetes). In contrast, molecular studies have noted a possible affinity to the Leotiomycetes. Here we review the taxonomic placement of Sarea using sequence data from seven phylogenetically informative DNA regions including ribosomal (ITS, nucSSU, mtSSU, nucLSU) and protein-coding (rpb1, rpb2, mcm7) regions. We combined available and new sequence data with sequences from major Pezizomycotina classes, especially Lecanoromycetes and Leotiomycetes, and assembled three different taxon samplings in order to place the genus Sarea within the Pezizomycotina. Based on our data, none of the applied phylogenetic approaches (Bayesian Inference, Maximum Likelihood and Maximum Parsimony) supported the placement of Sarea in the Trapeliales or any other order in the Lecanoromycetes. A placement of Sarea within the Leotiomycetes is similarly unsupported. Based on our data, Sarea forms an isolated and highly supported phylogenetic lineage within the " Leotiomyceta". From the results of our multilocus phylogenetic analyses we propose here a new class, order, and family, Sareomycetes, Sareales and Sareaceae in the Ascomycota to accommodate the genus Sarea. The genetic variability within the newly proposed class suggests that it is a larger group that requires further infrageneric classification.

<p>The fern family Pteridaceae is among the largest fern families in New Zealand. It comprises 17 native species among five genera. Traditionally the classification of Pteridaceae was based on morphological characters. The advent of molecular technology, now makes is possible to test these morphology-based classifications. The Pteridaceae has previously been subjected to phylogenetic analyses; however representatives from New Zealand and the South Pacific have never been well represented in these studies. This thesis research aimed to investigate the phylogenetic relationships of the New Zealand Pteridaceae, as well as, the phylogenetic relationships of the New Zealand species to their overseas relatives. The DNA sequences of several Chloroplast loci (e.g. trnL-trnF locus, rps4 and rps4-trnS IGS, atpB, and rbcL) were determined and the phylogenetic relationships of the New Zealand Pteridaceae and several species-specific question within the genus Pellaea and Adiantum were investigated. Results presented in this thesis confirm previously published phylogenetics of the Pteridaceae, which show the resolution of five major clades, i.e.,cryptogrammoids, ceratopteridoids, pteridoids, cheilanthoids, and the adiantoids. The addition of the New Zealand species revealed a possible South West Pacific groups formed by the respective genera, where New Zealand species were generally more related to one another than to overseas relatives. Within the New Zealand Pellaea, the analysis of the trnL-trnF locus sequence data showed that the morphologically-intermediate plants P. aff. falcata, responsible for taxonomic confusion, were more closely related to P. rotundifolia than to P. falcata. Furthermore, the species collected on the Kermadec Islands, previously thought to be P. falcata, are genetically distinct from the Australian P. falcata and they could constitute a new species. Adiantum hispidulum, which is polymorphic for two different hair types being used to distinguish them as different species, was also reinvestigated morphologically and molecularly. Morphological inspection of hairs revealed three hair types as opposed to the previous thought two, and furthermore, they correspond to three different trnL-trnF sequences haplotypes.</p>

Taxonomic Studies

During ongoing taxonomic studies with Tanaecium, we identified some morphological disparities between Tanaecium mutabile and the remaining species of the genus. Here, we reconstruct a molecular phylogeny of Tanaecium based on two molecular markers (i.e., the chloroplast ndhF and the nuclear pepC), and a broad sampling of members of the Arrabidaea and allies clade, where Tanaecium is included. In the newly constructed phylogeny, T. mutabile is nested within Fridericia, indicating the need for taxonomic arrangements. These findings are further supported by new morphological data (e.g., venation angle, domatia type, and corolla curvature). Based on these results, we formally transfer T. mutabile into Fridericia, and propose the necessary new combination. We further designate a new lectotype for Arrabidaea muehlbergiana, a synonym of T. mutabile. Morphological comparisons between T. mutabile and other morphologically similar species are presented.

Four species of Haploporus, H.angustisporus, H.crassus, H.gilbertsonii and H.microsporus are described as new and H.pirongia is proposed as a new combination, based on morphological characteristics and molecular phylogenetic analyses inferred from internal transcribed spacer (ITS) and large subunit nuclear ribosomal RNA gene (nLSU) sequences. Haploporusangustisporus, H.crassus and H.microsporus occur in China, H.gilbertsonii occurs in the USA, and the distribution of H.pirongia is extended from New Zealand to Australia. Haploporusangustisporus is characterized by the distinct narrow oblong basidiospores measuring 10.5–13.5 × 3.9–5 µm. Haploporuscrassus is characterized by the presence of ventricose cystidioles occasionally with a simple septum, dissepimental hyphae usually with a simple septum, unique thick-walled basidia and distinctly wide oblong basidiospores measuring 13.5–16.5 × 7.5–9.5 µm. Haploporusgilbertsonii is characterized by its large pores (2–3 per mm), a dimitic hyphal structure with non-dextrinoid skeletal hyphae and wide oblong basidiospores measuring 12–15 × 6–8 µm. Haploporusmicrosporus is characterized by distinctly small pores (7–9 per mm), the presence of dendrohyphidia, and distinctly small ellipsoid basidiospores measuring 5.3–6.7 × 3–4.1 µm. Haploporuspirongia is proposed as a new combination. Haploporusamarus is shown to be a synonym of H.odorus and Pachykytosporawasseri is considered a synonym of H.subtrameteus.
