A new ascomycete species, Bambusicola loculata, inhabiting decaying bamboo, is introduced based on morpho-molecular studies. Bambusicola loculata is characterized by immersed, dark, stromatic and loculate ascostromata, bitunicate, cylindrical-clavate asci and 1-septate, hyaline, narrowly fusiform ascospores, surrounded by an inconspicuous mucilaginous sheath. Maximum likelihood and Bayesian analyses of combined LSU, SSU, RPB2 and TEF1 gene sequence data as well as morphological characters show that our new taxon belongs to Bambusicola, Bambusicolaceae. The new species is compared with other morphologically and phylogenetically similar species.

We describe a new species of pitviper of the genus Atropoides from the Sierra de Botaderos and La Muralla, Honduras. The new species is easily distinguished from all other members of the genus, except A. picadoi from Costa Rica and Panama, by possessing more ventral scales (140 vs. 103–138). This new species differs from A. picadoi in being relatively small, less than 600 mm in total length (vs. reaching > 750 mm), having the posterior third of the body venter heavily melanized (vs. more than 50%), less than 50% of the underside of the tail melanized, and the postorbital stripe covering more than 50% of only one or two scales from the first temporal row and covering completely only the last scale of the row, at most (vs. 3–4 more than 50% melanized and the last two scales in the row usually completely melanized). In addition to morphological characters, molecular evidence also differentiates this new species from the other species of Atropoides (as recognized by Castoe et al. 2005). Using mitochondrial gene sequence data, they found the new species described herein to represent the sister species of A. occiduus, with 5.7 % sequence divergence separating these two taxa.

Β Tubulin

A new species, Pestalotiopsis licualacola, was isolated from grey leafspots of Licuala grandis (ruffled fan palm). It is morphologically distinct in having relatively small, greyish brown conidia (16–20 × 3–5 μm), and 1–3 short apical appendages without knobs. Phylogenetic analysis based on combination of ITS, β-tubulin and tef1 gene sequence data clearly distinguishes P. licualacola from other species in this genus, with ex-type sequence data in GenBank. Based on morphology and molecular phylogeny we describe it as a new species.

Gene Sequence Data

Coloration, gene-sequence data (H3, 12s, 16s), and subtle features in morphology support the description of two new species, both formerly regarded to represent accepted variants of Phimochirus holthuisi s.l. While color in life consistently separates these species from P. holthuisi s.s. and from each other, morphological distinctions are subtle and less than absolute in small specimens, being based on ventral spine counts of walking leg dactyls and relative development of the superior crest on the major chela. Molecular phylogenetic analyses clearly support the separation of sister clades, representing two new species, from P. holthuisi s.s. as well as other congeners available for analysis. Both of the new species are presently known to occur widely throughout the northern Gulf of Mexico, though one occurs more commonly in the northeastern and southeastern Gulf, and may range as far south as Suriname. The other has been taken primarily in the northwestern Gulf, and is not known from outside Gulf waters. While both of the new species appear restricted to relatively deep subtidal waters of the continental shelf, Phimochirus holthuisi s.s. is instead more commonly found in shallow nearshore tropical waters on or near coral reefs. Previous literature reports of P. holthuisi usually represent, at least in part, one or both of these two new species.

Three Pestalotiopsis isolates were obtained from leaves of Coffea arabica and Rhodomyrtus tomentosa. Among them, two isolates produced versicolorous conidia, and the other produced concolorous conidia. Phylogenetic analysis based on a combination of ITS, β-tubulin and tef1 gene sequence data clearly confirms that they belong to two species and distinguishes them from other species in this genus, with ex-type sequence data in GenBank. On the basis of evidence from morphology and molecular phylogeny they are described as new species, Pestalotiopsis coffeae-arabicae sp. nov. and P. rhodomyrtus sp. nov.

A New Species

Begonia fenshuilingensis X.X.Feng, R.K.Li & Z.X.Liu, a new species in Begonia sect. Platycentrum (Klotzsch) A.DC. (Begoniaceae) from southeastern Yunnan, China, is here described and illustrated. It morphologically resembles B. dryadis and B. daweishanensis, but differs by its fleshy trigonous-ellipsoid capsules without wings. Molecular phylogenetic analysis of ITS sequence data supports the new species as monophyletic, and distinct from the two similar species. Due to its limited distribution, we consider the new taxon as “Vulnerable D2” (VU D2) according to the IUCN Red List Categories and Criteria.

Isthmus Of Kra

The taxonomic identity of the Trimeresurus (Popeia) popeiorum complex from the Isthmus of Kra and to the north was investigated. Several studies over the last decade have produced several specimens and associated mtDNA sequence data for a variety of individuals of the T. popeiorum and “T. sabahi” complexes. Here, we combine four mitochondrial genes (12S, 16S, ND4, and CytB) from all available specimens in GenBank with the addition of five new specimens collected from the mainland, Tanintharyi Region of Myanmar. Maximum Likelihood and Bayesian analyses identified that T. popeiorum sensu lato is paraphyletic with two geographically distinct clades: a northern clade representing populations from northern Myanmar, Laos and northern Thailand and a southern clade representing samples from the Tanintharyi Region and adjacent west Thailand. While the two clades have considerable genetic distance, they appear to be morphologically identical, leading to the hypothesis that the southern clade represents a cryptic, undescribed species. Because they appear to be cryptic species and the limitation of only five specimens from the southern lineage, this does not permit us to formally describe the new species. In accordance to past molecular studies, we uncovered paraphyly and lack of genetic support for the validity of taxa within the T. sabahi complex. However, we suggest recognizing these populations as subspecies within T. sabahi.

A New Species

A new species, Strobilomyces minor, associated with host plants of Fagaceae, is introduced based on morphological and molecular studies. Strobilomyces minor is characterized by its small basidiomes, light yellowish brown appressed pyramidal scales on the pileus and stipe, large hymenophoral pores, and reticulate basidiospores with large meshes. Maximum Likelihood and Bayesian analyses based on four gene markers (rpb1, rpb2, tef1 and cox3) as well as morphological characters confirmed that this new taxon belongs to Strobilomyces and it is distinct from any known species. A morphological description with line drawings and SEM images for the species is provided.

Gene Sequence Data

Two asexual trichocladium-like species were recorded from coastlines in Japan and Thailand. Phylogenetic analysis of multi-gene sequence data placed them in Savoryella (Savoryellaceae), grouping with an unidentified strain isolated from submerged wood in a saline environment, but distinct from other Savoryella species. In this paper, we propose a new combination as Savoryella nypae based on Trichocladium nypae and a new species Savoryella sarushimana. Savoryella sarushimana differs from S. nypae in having larger conidial dimensions, with a rough to spiny surface and the proliferation of conidia. Detail morphological features coupled with sporulation in culture of the new taxa are illustrated. Notes on the phylogenetic placement of the discussed taxa and emendation of the genus Savoryella are provided.

Fissuroma taiwanense sp. nov. was collected from Shihnong Forest Area in Chiayi, Taiwan (Elevation 350m) and is the first report of a Fissuroma species from Hedychium (Zingiberaceae). The species is markedly different from extant species of Fissuroma in having broad cylindric-clavate asci with long, club-shaped apical and basal appendages and distinct thick mucilaginous sheath in ascospores. Combined analyses of LSU, SSU and tef1-α sequence data indicate a close relationship with F. maculans, the type species, but isolates of the new taxon are phylogenetically distinct. The new species is compared with other Fissuroma species and a comprehensive description and micrographs are provided.

Gene Sequence Data

A new species, Microthyrium propagulensis, collected in Yunnan Province, southwestern China is introduced. The species is typical of Microthyriaceae (Microthyriales) in having superficial thyriothecia with a poorly developed basal layer and a prominent darker central ostiole, bitunicate asci and 1-septate ascospores. It is similar to the generic type, M. microscopicum, but differs in having relatively small ascospores, with two apical cilia, which lie downloads from the ascospore apex at a 45° angle. Phylogenetic analysis based on combined LSU and SSU gene sequence data clearly place this species in Microthyrium, but distinguishes it from Microthyrium microscopicum. This second sequence from a Microthyrium species indicates that the putative sequence of the type of this genus is CBS has been correctly named and supports the distinctiveness of Microthyriales and Microthyriaceae.
