Two new species ofNeosartorya from Brazilian soil

Among the isolates from soil of corn and sugar cane plantations in São Paulo State, Brazil, two new species ofNeosartorya, N. botucatensis andN. paulistensis, are described and illustrated.Neosartorya botucatensis differs from the other known species of the genus in having ascospores with long spines on the convex walls.Neosartorya paulistensis is characterized by its ascospore walls with spinose and verruculose ornamentation. The former is compared with the closely related speciesN. spinosa, and the latter is closely related toN. glabra, N. pseudofischeri and N. stramenia.     

A new species ofRoumegueriella

A new species ofRoumegueriella (Ascomycetes; Hypocreales),R. pulchella, is described and illustrated. This fungus is characterized by its rapid growth on Czapek-yeast extract and YpSs agars at 37°C, bright yellow non-ostiolate ascomata, translucent membranaceous peridium, broadly clavate asci, and hyaline one-celled subglobose-ovoid ascospores ornamented with prominent spines. The holotype was isolated from soil in a sugarcane field in Okinawa, Japan.     

Two new species ofConiochaeta with a cephalothecoid peridium wall

Two new species ofConiochaeta, isolated from Japanese soils, are described and illustrated:C. cephalothecoides, which is characterized by dark brown ascomata clothed with short setae, cylindrical asci and ovoid to almond-shaped or pyriform ascospores with a longitudinal germ slit; andC. dumosa, which is characterized by dark brown ascomata clothed with short setae and dense hyphal hairs, cylindrical asci and ellipsoid-fusoid ascospores with a longitudinal germ slit. These species are distinguished from most species of the genus by the unique cephalothecoid peridium of their ascomata. The associated anamorphs of both species are assignable to the form-genusLecythophora.

Three common bryophilous fungi with meristematic anamorphs and phylogenetic alliance to Teratosphaeriaceae,Capnodiales

Bryophilous ascomycetes are an overlooked and poorly known fungal group. In this study, the extreme and small-sized niche of Polytrichum piliferum hyaline leaf tips was screened for the presence of these fungi in Finland. Three closely related species were found. Bryochiton perpusillus and Bryochiton monascus were identified from several samples, and DNA isolations revealed a third closely related species, Bryochiton sp. In addition, melanised hyphae, typical to the Bryochiton species, were present in all the samples. According to phylogenetic analyses consisting of combined small subunit (SSU), large subunit (LSU), and 5.8S rDNA sequences, and internal transcribed spacer (ITS) rDNA sequences, the species showed affinity with Teratosphaeriaceae within Capnodiales, and especially with black, meristematic species often inhabiting rock substrate in extreme environments. The connection was supported by meristematic growth of the Bryochiton species in culture. Bryochiton is the second sexual genus associated within the family Teratosphaeriaceae, and B. perpusillus, and B. monascus constitute examples of teleomorphs within a group of meristematic anamorphs. These findings emphasize the multiform diversity underlying poorly researched fungal groups, such as the bryophilous fungi.     

Two new species of Hippocrateaceae from Brazil

Two new species of Hippocrateaceae from Brazil are described and illustrated:Pristimera sclerophylla Lombardi, the one species of the genus that occurs in the xerophytic vegetation of northeastern Brazil, andCheiloclinium puberulum Lombardi, a species with puberulent inflorescences from the rain forests of the Amazon basin.

Xenocylindrocladium guianense andX. subverticillatum, two new species of hyphomycetes from plant debris in the tropics

Two new species of hyphomycetes,Xenocylindrocladium guianense andX. subverticillatum, are described from plant debris collected in French Guiana and Singapore, respectively. The genusXenocylindrocladium has thus far been known from one species,X. serpens, which was described from plant debris collected in Ecuador. The two new taxa are compared with and distinguished fromX. serpens based on morphology, cultural characteristics and phylogenetic analysis of DNA sequence data of the 5.8S rDNA with flanking ITS1 and ITS2 regions and the 5′ end of the β-tubulin gene. These species are also compared with other closely related hypocrealean taxa. Present collection data suggest that species ofXenocylindrocladium could be restricted to the tropics.     

Prosthecium species with Stegonsporium anamorphs on Acer

Data from microscopic morphology, single-spore cultures, and DNA analyses of teleomorphs and anamorphs support the recognition of five species of Prosthecium with Stegonsporium anamorphs on Acer: P. acerinum sp. nov., the teleomorph of S. acerinum; P. acerophilum comb. nov., formerly known as Dictyoporthe acerophila; P. galeatum comb. nov., originally described as Massaria galeata; P. opalus sp. nov.; and P. pyriforme sp. nov., the teleomorph of S. pyriforme s. str. The morphology of both type specimens and freshly collected material was investigated. The teleomorphs have brown ellipsoidal ascospores with five distosepta and often a longitudinal distoseptum. The anamorphs of all species described here belong to Stegonsporium; their connection to the Prosthecium teleomorphs was demonstrated by morphology and DNA sequences of single spore cultures derived from both ascospores and conidia. The anamorphs and teleomorphs of all five Prosthecium species are described and illustrated by LM images, and a key to these species is provided. As perceived from this work, S. pyriforme is restricted to Europe and does not occur in North America, whereas S. acerinum is restricted to North America, not found in Europe. The host associations given in the literature are revised and evidence is provided that only A. opalus, A. pseudoplatanus, and A. saccharum are confirmed hosts of Prosthecium with Stegonsporium anamorphs. Molecular phylogenetic analyses of tef1, ITS rDNA, and partial nuLSU rDNA sequences confirm that the species with Stegonsporium anamorphs are closely related to P. ellipsosporum, the generic type species. Stilbospora macrosperma is confirmed as the anamorph of P. ellipsosporum by DNA data of single spore isolates obtained from both ascospores and conidia.

Two new species of the genusMenziesia from Japan

Two species ofMenziesia, M. katsumatae andM. yakushimensis, are described as new to science. The former is characterized by having a long axis of the inflorescence with 15–20 bracts while the other species has a short axis with about ten bracts.M. katsumatae is restricted to the Hakusan range extending northward to Mt. Hōdatsuzan in the Noto Peninsula.M. yakushimensis has been considered asM. purpurea Maxim. in Kyūshū, but it is clearly distinguishable from the latter by the color and shape of the corolla and the presence of fasciculate glandular-hairs at the base of the corolla lobes. It is endemic to the higher altitudes of Yaku-shima Island, Kagoshima Prefecture.     

Isolation and identification ofNeosartorya species from house dust as hazardous indoor pollutants

Isolation of ascomycetous microfungi from 58 house dust samples from detached and apartment dwellings around Kobe City revealed that species ofTalaromyces, Eurotium andNeosartorya were common ascomycetous propagules in the house dust.Neosartorya species accounted for 8.3% of the total identified isolates, of whichN. pseudofischeri was the main constituent, indicating that it may be a common potential fungal pathogen in the dwelling environment. Based on the specimens collected,N. pseudofischeri is described and illustrated as new to Japan.
