Balsam Poplar

Knufia endospora , a species described previously on the basis of cultured material, was found forming distinctive sporodochia on the bark of balsam poplar. Phylogenetic analyses of this fungus and some allied species indicated that (i) it forms a monophyletic group with Knufia cryptophialidica (type species of Knufia ) and with Coniosporium perforans , Coniosporium epidermidis and Phaeococcomyces chersonesos and (ii) P. chersonesos and Sarcinomyces petricola are conspecific. These Coniosporium and Phaeococcomyces species also shared major morphological characteristics with Knufia in culture and were morphologically and phylogenetically distant from the type species of their respective genera. The following new combinations are proposed: Knufia perforans (Sterflinger) Tsuneda, Hambleton & Currah; Knufia epidermidis (D.M. Li, de Hoog, Saunte & X.R. Chen) Tsuneda, Hambleton & Currah; and Knufia chersonesos (Bogom. & Minter) Tsuneda, Hambleton & Currah. Phaeococcomyces catenatus and Phaeococcomyces nigricans (type species of Phaeococcomyces) were morphologically similar but phylogenetically distant from each other and from Knufia.

Grammatuslabyrinthinusgen. et sp. nov. is proposed based on DNA sequences data and morphological characteristics. It is known so far from southern, tropical China. The new species is characterised by an annual, resupinate basidiocarp with a shallow, subporoid hymenophore, a hymenium restricted to the bottom of the tubes, a dimitic hyphal system, presence of encrusted skeletocystidia and dendrohyphidia, longitudinally septate basidia and smooth, oblong-ellipsoid to cylindrical, acyanophilous basidiospores. Phylogenetic analyses based on ITS + nLSU DNA sequences data indicate that G.labyrinthinus belongs to Auriculariaceae in which it has an isolated position. Phylogenetic inferences show G.labyrinthinus to be related to Heteroradulum. However, the ITS sequences similarity between G.labyrinthinus and H.kmetii, the type species of Heteroradulum, were 89.84% and support the establishment of the new genus. Inversely, Heteroradulumsemis clustered with G.labyrinthinus with strong support and it is transferred to Grammatus.

The fern family Blechnaceae, with about 250 species, has traditionally comprised one large genus, Blechnum, plus seven to nine smaller genera, most with fewer than 10 species. Several phylogenetic analyses strongly suggest that Blechnum in the traditional sense is not a monophyletic group. We propose a new classification for the family, with three subfamilies and 24 genera. All genera are described and new combinations are provided, with an estimate of species number for each genus. We also provide a key for the identification of the genera.

Phylogenetic analyses based on 10 molecular markers unquestionably support a sister relationship between Albidella nymphaeifolia and the Caldesia oligococca species group. The type species of the genus Caldesia is excluded from this monophylum. These results are unsurprising in the light of morphological characteristics, but require three new combinations in Albidella to render both Albidella and Caldesia monophyletic. These new combinations are provided here. Under the new circumscription, Albidella shows a disjunct distribution pattern, with one species in the Caribbean region and three species distributed from tropical Africa and along the margins of the Indian Ocean to Australia.

Geographic Overlap

The fern genus Microsorum is not monophyletic, with previous phylogenetic analyses finding three lineages to group not with the type species, but to form a grade related to the 13 species of Lecanopteris. These three lineages have recently been recognised as separate genera: Bosmania, Dendroconche, and Zealandia. Here, we explore the morphological characterisation of Lecanopteris and these other three lecanopteroid genera. While the traditional circumscription of Lecanopteris has seemed sacrosanct, its defining morphological character states of rhizome cavities and ant brooding associations occur in other lecanopteroid ferns and elsewhere in the Polypodiaceae. Instead, we suggest that the morphological characterisation of an expanded Lecanopteris including the Dendroconche and Zealandia lineages is just as good, if not better, with the pertinent character states being the absence of sclerenchyma strands in the rhizome and at least some fronds having Nooteboom’s type 5 venation pattern. This wider circumscription is also better able to accommodate phylogenetic uncertainty, and it means that groups of species traditionally placed together in a single genus are not distributed across different genera. General users familiar with the narrower circumscription of Lecanopteris will not be significantly disrupted, because there is little geographic overlap with the lineages added to the genus. Consequently, we make new combinations in Lecanopteris for 11 species and one subspecies.

The Iodosphaeriaceae is represented by the single genus, Iodosphaeria, which is composed of nine species with superficial, black, globose ascomata covered with long, flexuous, brown hairs projecting from the ascomata in a stellate fashion, unitunicate asci with an amyloid apical ring or ring lacking and ellipsoidal, ellipsoidal-fusiform or allantoid, hyaline, aseptate ascospores. Members of Iodosphaeria are infrequently found worldwide as saprobes on various hosts and a wide range of substrates. Only three species have been sequenced and included in phylogenetic analyses, but the type species, I. phyllophila, lacks sequence data. In order to stabilize the placement of the genus and family, an epitype for the type species was designated after obtaining ITS sequence data and conducting maximum likelihood and Bayesian phylogenetic analyses. Iodosphaeria foliicola occurring on overwintered Alnus sp. leaves is described as new. Five species in the genus form a well-supported monophyletic group, sister to the Pseudosporidesmiaceae in the Xylariales. Selenosporella-like and/or ceratosporium-like synasexual morphs were experimentally verified or found associated with ascomata of seven of the nine accepted species in the genus. Taxa included and excluded from Iodosphaeria are discussed.

Subfamilial Classification

A worldwide checklist is provided for the family Endomychidae (Coleoptera: Cucujoidea). An updated subfamilial classification is presented, based on recent higher-level phylogenetic analyses and incorporating many recently described taxa. At present, Endomychidae contains 1782 valid species and subspecies in 130 genera organized into 12 subfamilies. Two new synonyms are recognized: Symbiotes latus Redtenbacher, 1849 = Symbiotes latus var. roberti Falcoz & Roman, 1930 syn. nov.; and Cholovocerida Belon, 1884 = Displotera Reitter, 1887b syn. nov. Two new combinations are proposed: Cholovocerida ecitonis (Wasmann, 1890) for Coluocera ecitonis Wasmann, 1890 comb. nov.; and Cholovocerida maderae (Wollaston, 1854) for Cholovocera maderae Wollaston, 1854 comb. nov. Loeblia ceylanica Dajoz, 1972a is here designated as the type species for Loeblia Dajoz, 1972a, and Rhymbus hemisphaericus Gerstaecker, 1858 is designated as the type species for Rhymbus Gerstaecker, 1858. Nomen nudum status is proposed for Mycetaea tafilaletica Smirnoff, 1957. Thirty-two species originally described under Corynomalus Chevrolat, 1836 and subsequently transferred to Amphix Laporte, 1840, have been returned to Corynomalus. Known fossil taxa are summarized.

Molecular Phylogenetic

Recent molecular systematic research has indicated the need for a revised circumscription of generic boundaries in subtribe Castillejinae (tribe Pedicularideae, Orobanchaceae). Based on a well-resolved and well-supported phylogenetic hypothesis, we present a formal reclassification of the major lineages comprising the Castillejinae. Prior to this treatment, subtribe Castillejinae included Castilleja (ca. 190 spp.), Cordylanthus (18 spp.), Orthocarpus (9 spp.), Triphysaria (5 spp.), and the monotypic genera Clevelandia and Ophiocephalus. In the classification presented here, Orthocarpus and Triphysaria retain their current circumscriptions, Castilleja is expanded to include Clevelandia and Ophiocephalus, and Cordylanthus is split into three genera; a key to the genera as they are recognized here is provided. Two new combinations, Castilleja beldingii and Castilleja ophiocephala, are proposed within the expanded Castilleja. The concept of Cordylanthus is restricted to the 13 species formerly recognized as subg. Cordylanthus, while subg. Dicranostegia and subg. Hemistegia are elevated to genus level (Dicranostegia and Chloropyron, respectively). We resurrect the generic name Chloropyron for the halophytes previously recognized as subg. Hemistegia. Five new combinations are proposed for Chloropyron (Chloropyron maritimum subsp. canescens, Chloropyron maritimum subsp. palustre, Chloropyron molle subsp. hispidum, Chloropyron palmatum, and Chloropyron tecopense). In addition to the formal classification, we provide phylogenetic clade definitions for Castillejinae, each of the genera, and two additional clades that are not assigned formal ranks. Morphological characteristics used to recognize traditional groups are evaluated, and synapomorphies are discussed. Finally, the current infrageneric classifications for Castilleja and Cordylanthus are evaluated in light of the recent molecular phylogenetic analyses.

Internal Transcribed Spacer Sequences

In the present study, two new filamentous cyanobacterial strains (NUACC12 and NUACC15) were described based on a comprehensive study of morphological characteristics and molecular analyses. The novel strains were isolated from a shallow freshwater pond in the central region of Thailand. The morphological features of both strains are similar to those of Wollea species, W. ambigua, but are different in the dimensions of heterocyte and akinete cells as well as the absence of a sheath around the trichome. Phylogenetic analyses based on 16S rDNA and 16S–23S rDNA internal transcribed spacer sequences (ITS) revealed that new strains formed a robust supported clade which does not belong to the same clade with the type species of other cyanobacterial genera. Moreover, 16S rDNA sequence similarity between new strains and other putatively related taxa such as Wollea, Amphiheterocytum, Sphaerospermopsis, and Raphidiopsis raciborskii ranged from 96.1–97.4%, a level of similarity low enough for separating species differences. The unique patterns of the ITS secondary structure also clearly support two new strains representing a distinct cyanobacterial species. Considering all the results obtained in the present study, we here name the new genus Neowollea gen. nov., with the type species N. manoromense sp. nov. Based on morphology, ecology, 16S rDNA data and D1–D1′ helix structure, we also propose N. salina comb. nov. (basionym Wollea salina) as an additional species in the novel genus. Furthermore, the results of PCR amplification and GC/MS/MS analysis confirmed that two N. manoromense strains could produce an odorous compound, geosmin.

Generic Concept

New collections of six Squamarina species from type localities in China were studied. The comparison of morphological characteristics and secondary metabolites with those of the type specimens and phylogenetic analyses suggest that S. callichroa and S. pachyphylla belong to Rhizoplaca, S. semisterilis belongs to Lobothallia and S. chondroderma should be retained in Lecanora temporarily. Only two species, S. kansuensis and S. oleosa, remain in Squamarina. The new combinations Lobothallia semisterilis (H. Magn.) Y. Y. Zhang, Rhizoplaca callichroa (Zahlbr.) Y. Y. Zhang and R. pachyphylla (H. Magn.) Y. Y. Zhang are proposed. Detailed descriptions to aid the identification of these species, distributions and phylogenetic trees, based on multiple collections, are presented. The generic concept of Squamarina is recircumscribed in this study.

Eleven Species

Here, based on phylogenetic analyses of 18 taxa and 57 morphological characters, we propose a new firefly genus, Costalampysgen. nov., to accommodate eleven species. Five new species are herein described: C. bellasp. nov., C. capixabasp. nov., C delicatasp. nov. (designated as type species), C. joanaesp. nov. and C. minimasp. nov. In addition, six species are redescribed and transferred from other genera: C. bisbinotata (Pic) comb. nov., transferred from Platylampis Motschulsky; C. decorata (Olivier) comb. nov., transferred from Ethra Laporte; C. pauper (Olivier) comb. nov., transferred from Cladodes Solier; as well as C. klugii (Motschulsky) comb. nov., C. quadriguttata (Gorham) comb. nov., and C. tricolor (Gorham) comb. nov., transferred from Lucidota Laporte. Costalampysgen. nov. is tentatively placed in Lampyrinae, and is diagnosed by: antennae with 11 articles, III–X basally flabellate, lacking dense and upright bristles; clypeus connected to frons by membrane, pygidium rounded; sternum VIII mucronate; phallus with dorsal plate enlarged apically, projecting ventrally and partially embracing the internal sac. Our phylogenetic analyses supported both the monophyly of Costalampysgen. nov. and the new combinations proposed. However, the relationship among congeneric species was poorly resolved. Finally, we provide illustrations of diagnostic features, distribution maps, as well as a key to Costalampysgen. nov. species, based on males.
