A New Species

Stictidaceae comprises taxa with diverse lifestyles. Many species in this family are drought resistant and important for studying fungal adaptation and evolution. Stictidaceae comprises 32 genera, but many of them have been neglected for decades due to the lack of field collections and molecular data. In this study, we introduce a new species Fitzroyomyces hyaloseptisporus and a new combination Fitzroyomycespandanicola. We also provide additional morphological and molecular data for Ostropomyces pruinosellus and O. thailandicus based on new collections isolated from an unidentified woody dicotyledonous host in Chiang Rai, Thailand. Taxonomic conclusions are made with the aid of morphological evidence and phylogenetic analysis of combined LSU, ITS and mtSSU sequence data. Characteristics such as the shape and septation of ascospores and conidia as well as lifestyles among genera of Stictidaceae are discussed.

A New Species

A new species, Camellia psilocarpa (Theaceae), from Guangdong Province, China, is described and illustrated. It is morphologically most similar to C. magnocarpa, from which it differs by having ovate-oblong leaves with apex caudate or long acuminate, bracteoles and sepals 10-12, grayish white velutinous outside, and especially smaller fruit. The morphological evidence shows that the new species is a member of Camellia sect. Camellia. Additionally, a molecular and phylogenetic analysis using two chloroplast DNA markers also gave support to its taxonomic position.

Colletotrichum sonchicola, sp. nov. from Sonchus sp. (dandelion tribe) in Forlì-Cesena Province, Italy, is introduced using morphological and molecular data. Combined phylogenetic analysis of ITS, GAPDH, CHS, ACT and TUB2 sequence data demonstrate that C. sonchicola is a distinct species within the dematium species complex. The new species is illustrated and compared with related taxa. This provides the first record of a Colletotrichum species from the genus Sonchus.

A New Species

The recent delimitation of the cambalopsid genera Hypocambala and Glyphiulus is debatable. The focus of controversy is whether the presence of crests on the trunk rings is an appropriate key character dividing these two genera. To address this issue, we conducted a molecular phylogenetic analysis including species with or without crests belonging to Hypocambala and species with crests belonging to Glyphiulus. The results of the phylogenetic analysis suggest that cambalopsids with crests are monophyletic and sister to a species without crests. Hypocambala polytricha, a cambalopsid with crests that is in a clade with crested Glyphiulus species, should be transferred to Glyphiulus. Therefore, a new combination is proposed, Glyphiulus polytrichus comb. nov. In addition, a discussion on the boundary between these two genera and a description of a new species, Hypocambala zizhongi sp. nov., are provided.

Idiococcobius Hayat, syn. nov., is synonymised with Coccobius Ratzeburg, based on morphological and molecular data from a new species of Coccobius from Malaysian Borneo. The new species is sufficiently similar morphologically to the type species of Idiococcobius to place it unambiguously within that genus, but molecular data from the new species, and a reassessment of the morphology of Idiococcobius, indicate synonymy of the two genera. Idiococcobius encarsoides Hayat is therefore transferred to Coccobius; resulting in the new combination: Coccobius encarsoides (Hayat), comb. nov.Coccobius islandicus Geng & Polaszek, sp. nov, is described from morphology and DNA sequence data.

A New Species

Fulvifomes submerrillii (Hymenochaetaceae, Basidiomycota) is described from China based on both of morphological evidence and molecular data. The new species is characterized by perennial, pileate basidiocarps, encrusted, smooth pileal surface, 6–7 pores per mm with thick dissepiments, a dimitic hyphal system with interwoven skeletal hyphae, absence of setae or setal hyphae, ventricose cystidioles, and broadly ellipsoid, yellowish brown, thick-walled, smooth basidiospores, 4.7–5 × 3.7–4 μm. Phylogenetic analysis inferred from ITS and nLSU sequences indicates that the new species forms a separate well-supported clade, closely related to F. merrillii. However, F. merrillii has larger pores (4–5 per mm), a subdimitic hyphal structure in context, the contextual skeletal hyphae which regularly arranged and become swollen in KOH, and slightly longer (4.5–6 μm long) basidiospores. Moreover, one new combination (F. rigidus) is revived from synonym under Inonotus rigidus.

Lines Of Evidence

Abstract The systematics and taxonomy of the broadly distributed bats of the genus Cynomops has changed considerably in the last few years. Among the major changes, Cynomops abrasus was split into two species of large-bodied forms (Cynomops mastivus and C. abrasus) distributed east of the Andes. However, large Colombian specimens identified as C. abrasus from the western side of the Andes had yet to be included in any revisionary work. Phylogenetic analysis performed in this study, using mtDNA sequences (Cytochrome-b), revealed that these Colombian individuals are more closely related to Cynomops greenhalli. Morphological and molecular data allowed us to recognize populations from western Colombia, western Ecuador and northwestern Peru, as members of a new species of Cynomops. Characters that allow for its differentiation from C. greenhalli include a larger forearm, paler but more uniform ventral pelage, more globular braincase, and well-developed zygomatic processes of the maxilla (almost reaching the postorbital constriction). This study serves as another example of the importance of including multiple lines of evidence in the recognition of a new species. Given its rarity and the advanced transformation of its habitat, this new species is particularly important from a conservation perspective.

A New Species

Abstract During a parasitological survey of fishes at Iguazu National Park, Argentina, specimens belonging to the allocreadiid genus Auriculostoma were collected from the intestine of Characidium heirmostigmata. The erection of the new species is based on a unique combination of morphological traits as well as on phylogenetic analysis. Auriculostoma guacurarii n. sp. resembles four congeneric species – Auriculostoma diagonale, Auriculostoma platense, Auriculostoma tica and Auriculostoma totonacapanensis – in having smooth and oblique testes, but can be distinguished by a combination of several morphological features, hosts association and geographic distribution. Morphologically, the new species can be distinguished from both A. diagonale and A. platense by the egg size (bigger in the first and smaller in the last); from A. tica by a shorter body length, the genital pore position and the extension of the caeca; and from A. totonacapanensis by the size of the oral and ventral sucker and the post-testicular space. Additionally, one specimen of Auriculostoma cf. stenopteri from the characid Charax stenopterus (Characiformes) from La Plata River, Argentina, was sampled and the partial 28S rRNA gene was sequenced. The phylogenetic analysis revealed that A. guacurarii n. sp. clustered with A. tica and these two as sister taxa to A. cf. stenopteri. The new species described herein is the tenth species in the genus and the first one parasitizing a member of the family Crenuchidae.

A New Species

A new species of Cymbidium (Orchidaceae), Cymbidium xichouense, from Yunnan Province, China, is described and illustrated based on morphological evidence and molecular analyses. The new orchid is morphologically similar to C. qinbeiense, but it has several morphological features that distinguish it from C. qiubeinense and all other recognized species in Cymbidium. Phylogenetic analyses based on nuclear (ITS) and plastid DNA (matK) were conducted, and the results also supported the status of C. xichouense as a new species, which is sister to C. qiubeiense.

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.
