Two New Species

In the present study, two new species of Nitzschia Hassall, Nitzschia pusilluhasta sp. nov. and Nitzschia australodesertorum sp. nov. are described from reservoirs in the state of São Paulo southeast Brazil. The morphology of the new species was analysed using light and electron microscopy. Nitzschia pusilluhasta is distinguished from morphologically related species by its valve outline, the shape of apices and fibulae, the absence of a gap between central fibulae, and the density of striae and areolae. Nitzschia australodesertorum differs from morphologically similar species in its valve outline, the shape of apices and fibulae, the presence of a gap between the central fibulae, and the density of fibulae and striae. The morphology and ecology of the new species are discussed and compared with morphologically related taxa. Information on the co-occurrence of other diatom species in the samples is also provided.

Morphological And Molecular Data

Crangonyx ephemerus n. sp. and Crangonyx pseudoephemerus n. sp. are described from the headwaters of the St. Marks River in Leon County, Florida, based on detailed morphological and molecular comparisons with the closely related species Crangonyx floridanus Bousfield, 1963. The morphological and molecular data, including three species delimitation models, lend support to the hypothesis that the taxon C. floridanus sensu lato represents a species complex. Diagnostic morphological characteristics are highlighted and discussed within this group to assist in future morphological analyses.

Astragalus Sect

Following study of specimens belonging to Astragalus L. sect. Ammodendron Bunge collected from northeastern Iran, two new species and a new record for Iran are described and reported. Astragalus ayatollahii Nasseh, Joharchi & F. Ghahrem. differs from A. biarjmandicus Podlech & Zarre and A. inchebroonensis Maassoumi in having longer racemes with more flowers, only white trichomes on the calyx, and one pair of leaflets in the lower leaves and two pairs in the upper leaves. Astragalus gonabadensis Nasseh, Joharchi & F. Ghahrem. differs from A. baharensis F. Ghahrem. and A. macrobotrys Bunge in characters of the calyx and legume trichomes. Descriptions, distribution maps, and comparative tables of morphological characteristics for these taxa are presented. In addition, the first record of A. excedens Popov & Kult. in the flora of Iran is reported.

Two New Species

Two new species of Euphorbiaceae (sensu stricto), Mallotus bicarpellatus (Acalyphoideae) and Croton nepalensis (Crotonoideae), are described from Nepal. Mallotus bicarpellatus is closely related to M. philippensis but differs in having 1 or 2 pairs of leaf glands distinctly separated from the petiole attachment, pistillate flowers with staminodes and longer pedicels, and fewer locules and stigmas. Croton nepalensis differs from C. tiglium in having leaves with truncate, subcordate or rounded base, smaller, broadly ovoid capsules, and smaller seeds. A table is provided showing how Croton nepalensis differs from other closely related species. Croton himalaicus is here regarded as a synonym of C. tiglium, though it has been treated variously as a distinct species or a synonym of C. tiglium or C. birmanicus by recent authors. Distribution maps and graphs of altitudinal distribution are given for the new species.

Two New Species

Two new species of Perenniporia, P. pseudotephroporasp. nov. and P. subcorticolasp. nov., are introduced respectively from Brazil and China based on morphological characteristics and molecular data. Perenniporia pseudotephropora is characterised by perennial, pileate basidiocarps with distinctly stratified tubes, grey pores, tissues becoming dark in KOH, a dimitic hyphal system with slightly dextrinoid arboriform skeletal hyphae and broadly ellipsoid to subglobose, truncate, weakly dextrinoid, cyanophilous basidiospores, measuring 4.9–5.2 × 4–4.8 μm. Perenniporia subcorticola is characterised by resupinate basidiocarps, yellow pores with thick dissepiments, tissues becoming dark in KOH, flexuous skeletal hyphae, ellipsoid, truncate and slightly dextrinoid basidiospores, measuring 4.2–5 × 3.5–4.2 µm. The morphologically-similar species and phylogenetically closely-related species to the two new species are discussed.

Two New Species

The genus Plectosphaerella is the largest genus in the family Plectosphaerellaceae. Some species are plant pathogens, whereas others are soil-borne. Seven Plectosphaerella isolates were collected from various locations in the southwest of China. Using multi-locus phylogenetic (LSU, ITS, EF1α, RPB2) analyses combined with morphological characteristics, two new species, Plectosphaerella guizhouensissp. nov. and Plectosphaerella nauculasporasp. nov. are described, illustrated and compared with related species.

Geographical Scope

Typhrasa is a rare genus that comprises two species and that has previously been reported only from Europe and North America. The present study expands the geographical scope of the genus by describing two new species – T. polycystis and T. rugocephala – from subtropical China. The new species are supported by morphological characteristics and phylogenetic analyses (ITS, LSU and tef-1α). The new species have very similar morphological characteristics and are 98% similar in their ITS region. However, T. rugocephala has two types of long gills at the same time, rarely fusiform pleurocystidia with rostrum. Detailed descriptions, colour photos, illustrations and a key to related species are presented in this paper.
