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.

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.

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.

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.

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.

A New Species

A new species, Pseudodactylaria brevis, is described, illustrated and compared with other Pseudodactylaria and Dactylaria-like taxa. Evidence for the new species is provided by morphological comparison and sequence data analyses. Pseudodactylaria brevis can be distinguished from other Pseudodactylaria and Dactylaria-like species by its short hyaline conidiophores and fusiform, 1-septate hyaline conidia. Phylogenetic analysis of LSU and ITS sequence data was carried out to determine the phylogenetic placement of the species and confirm the taxonomic status of Pseudodactylariaceae.

A New Species

A new species of Maytenus has been discovered in the Brazilian Atlantic Forest. The new taxon, Maytenus nemorosa, occurs mostly in ombrophilous rain forests at an elevation of 500 m to 1200 m. Maytenus nemorosa resembles M. gonoclada but differs from it by possessing oblong-elliptical leaves with entire margins and larger fruits with thicker pericarp walls. A phylogenetic analysis was conducted with nrITS and plastid matK regions, including the new species and additional taxa available from the NCBI-GenBank. The results from the phylogenetic analysis places Maytenus nemorosa nested within a clade of species that have fruits possessing a coriaceous pericarp and close to both Maytenus gonoclada and Maytenus salicifolia, as expected from morphological similarities. Additionally, M. cardenasii and M. erythrocarpa, from Bolivia, are both recognized as new synonyms for M. floribunda after an examination of their descriptions, types, and diverse collections.

Aspergillus fuscicans, a new species within Aspergillus section Usti from Argentinean semi-arid soil is introduced. Molecular, morphological and physiological studies were conducted, based on sequence analysis of partial β-tubulin and calmodulin sequence data. Aspergillus fuscicans formed a distinct, well-defined clade related to A. calidoustus and A. pseudodeflectus. In addition, A. fuscicans was able to grow and sporulate at 37 ºC, and had a negative Ehrlich reaction. Morphological and physiological features could be used to differentiate the new species from its phylogenetically related taxa.

A New Species

A new species, Akanthomyces neocoleopterorum, which was isolated from an infected ladybug, is introduced. Morphological comparisons with extant species and DNA-based phylogenies from analysis of a multigene dataset support the establishment of the new species. It differs from other species by having mononematous and verticillium-like conidiophores, longer phialides, and mostly cylindrical conidia. Both the morphological identification and phylogenetic analysis of combined ITS, LSU, RPB1, RPB2 and TEF sequence data support A. neocoleopterorum as a new species in the genus Akanthomyces.

During a survey of entomopathogenetic fungi from Southwest China, a new species, Akanthomyces lepidopterorum was found on an undetermined lepidopteran larva. It differs from other species based on mostly smaller conidia, mononematous conidiophores and moderate length of phialide. Both the morphological identification and phylogenetic analysis of combined ITS, LSU and RPB2 sequence data support A. lepidopterorum as a new species. A new combination is also proposed in the genus Akanthomyces.
