Abstract: Currently described as part of Hymenogastraceae, Gymnopilus comprises up to 200 species distributed around the world, and 23 of these are found in Brazil. In this study, we discovered interesting specimens of G. dilepis growing with Zoysia japonica (Poaceae) grass in an urban area in the State of Paraíba. Originally described from Sri Lanka, this report treats a new and interesting record of this entity from Brazil. We also discuss whether to consider G. lepidotus as a synonym of G. dilepis based on morphological and phylogenetic evidence. Thus, as conclusion we prefer to maintain them as distinct entities and our material as G. dilepis based on morphological and ecological aspects.
摘要：Gymnopilus目前被描述为Hymenogastraceae的一部分，包括多达200个物种，分布在世界各地，其中23个物种在巴西被发现。在这项研究中，我们在帕拉伊巴州的一个城市地区发现了与 Zoysia japonica（Poaceae）草一起生长的有趣的 G. dilepis 标本。该报告最初描述自斯里兰卡，是巴西对这一实体的一个有趣的新记录。根据形态学和系统发育证据，我们还讨论了是否将 G. lepidotus 视为 G. dilepis 的异名。因此，作为结论，我们倾向于将它们视为不同的实体，并根据形态学和生态学方面的证据将我们的材料视为 G. dilepis。

A new genus and species, Venturioscypha nigropila, is proposed for a minute inoperculate discomycete with long, cylindrical, partly flexuous, dark blackish-brown, smooth, finally thick-walled hairs. It has been collected repeatedly in Europe on dead, corticated branches of Pinus spp. attached to living or recently dead trees. At first glance the species resembles members of Pirottaea (Pyrenopezizaceae), but the relationship is shown by molecular phylogenetics to be close to Hyphodiscus, Hyphopeziza, Fuscolachnum, and Venturiocistella (Hyphodiscaceae). These genera differ in having hairs with more or less conspicuous warts, in Hyphopeziza also with glassy solidifications, and Venturiocistella in having in addition long, stiff, thick-walled, apically acute, dark brown hairs, which are warted in their lower part. The hair wall of Venturioscypha appears superficially smooth, but the surface is inconspicuously pitted as viewed under light microscopy. Venturioscypha is unique in Hyphodiscaceae by its peculiar hairs, inamyloid asci with a thin apical wall that ruptures irregularly by a terminal split at spore discharge, spores with a delicate sheath, and apothecial proliferation.

This article deals with the taxonomy of three species belonging to Cortinarius subgenus Telamonia section Flexipedes. The micromorphologies and mostly ITS gene regions were examined from the lectotypes and some syntypes of Cortinarius phaeopygmaeus J. Favre and C. rusticellus J. Favre. Cortinarius phaeopygmaeus appeared to be a previously unrecognized species. Cortinarius rusticellus is reduced to a synonym of C. comatus J. Favre. Its lectotype and protologue agreed with C. comatus. The syntype of C. rusticellus was conspecific with C. lamoureae Bon. Cortinarius chrysophilus is described as new from Salix vegetation on boreal seashores and in the alpine zone. It belongs to the C. cucumisporus complex.

Moist chamber cultures are valuable for myxomycete research and can be used for the analysis of ecological patterns with implications in ecosystem conservation programs. However, to make comparisons between datasets valid, the method should be redesigned considering potential biases affecting the generation of results. In the present study, both the effect of the general climate of the laboratory and two microclimatic variables within the moist chamber were studied in relation with the obtained data. Of all the recorded variables, temperature was observed to affect the results, both at the level of the general laboratory climate and in relation with the microclimate of the moist chamber. Increments in laboratory and moist chamber temperature increased the probability, three or fourfold, associated with a higher number of records or species within a group of equivalent samples. Such probabilistic differences are significant enough to suggest that using the moist chamber technique in “standard” laboratory conditions is not enough for cross-dataset comparisons that increase the potential of myxomycete data for applications outside of the biological sciences.

Amanita indogrisea is described here as a new species from coniferous forests in the Union Territory of Jammu and Kashmir, India based on morpho-anatomy and molecular data. This species is characterized by its small to medium-sized basidiomata, ash grey to lilac-grey pileal surface with ash grey to greyish brown pulverulent-floccose to felted veil remnants, ash grey to greyish-white stipes with ovoid to ellipsoid basal bulb, ellipsoid to elongated basidiospores (10.5–15.0 × 7.0–10.0 μm) and the absence of clamps in all tissues. Molecular phylogenetic analysis based on nuclear ribosomal large subunit (nrLSU) sequences confirmed its identity as a new species nested within A. subgen. Amanitina sect. Roanokenses. Description of the new species is provided in this study.

In this study, we examined the impacts of a bushfire on a community of myxomycetes (also known as plasmodial slime moulds or myxogastrids) in northeastern New South Wales, Australia. Using the moist chamber culture technique, we prepared 40 moist chamber cultures from four different substrates. We collected the same four types of substrates on either side of a fire line approximately six months post-fire in order to assess what impact fire had on the myxomycete communities. Sixty percent of moist chamber cultures yielded evidence (plasmodia or fruiting bodies) of myxomycetes representing eleven species in eight genera. But only 40% of samples from the burned site were positive for myxomycetes, and only one species produced fruiting bodies. In contrast, 80% of samples from the unburned site were positive, and all eleven species were recorded. These data suggest that fire reduced the abundance and diversity of the myxomycete community at our site.

Cyanoboletus macroporus belonging to C. pulverulentus species complex is designated as a new species from the moist temperate and sub-alpine oak forests of Pakistan after in depth macroscopic, microscopic and phylogenetic analyses using the ITS region of nrDNA as well as comparison with allied taxa. This species belonging to Boletoid group is morphologically distinguished from allied taxa (Cyanoboletus flavosanguineus, C. hymenoglutinosus, C. pulverulentus, C. rainisii, and C. sinopulverulentus) by wider openings of pores. C. macroporus is also phylogenetically distinct from C. sinopulverulentus and C. pulverulentus, the most closely related species. Phylogenetic analysis outlined the existence of previously unknown species of this genus. Field photographs of fresh basidocarps and line drawings of micro-characters are provided along with a phylogenetic tree as well as a comparison table and a key of distinctive features of all the species in this genus. This is the first authentic species belonging to Cyanoboletus from Pakistan. Previously, only C. pulverulentus has been mentioned in literature, but no morphological data is available regarding this report. With the addition of this taxon, species number of Cyanoboletus will increase to eight. From Pakistan, despite of the fact that there is great diversity of mushrooms in moist temperate areas (Yousaf et al. 2012), this is the first study that describes a species belonging to Cyanoboletus genus. Previously only one ambiguous species, Cyanoboletus pulverulentus, has been mentioned in literature (Iqbal & Khalid 1996), but with no available materials that could confirm this finding. In this study, Cyanoboletus macroporus is described as a new to science and increase the current species number of Cyanoboletus to eight.

Long-term monitoring and phenological patterns of microbial communities are rare in the scientific literature. Myxomycetes have life cycle characteristics that allow both to be documented. The present study summarizes the integrated floristic and bioclimatic components of a 30-month assessment of myxomycete sporocarps in a premontane tropical forest in Turrialba, Costa Rica. Based on monthly visits and a standard sampling effort of 120 minutes per visit, myxomycetes were recorded on leaves, twigs, and logs on the ground by two to three people in 20-minute periods associated with six different collecting sites within a 34-hectare successional forest patch. Biological data were analyzed using three recorded climatic variables obtained in situ during the complete period of study. Also, the Oceanic Niño Index (ONI), provided by NOAA, an estimate of El Niño-Southern Oscillation (ENSO), was evaluated in the analyses. Overall, 54 species and 2245 records of myxomycetes were recorded, with an average of 14.5 species (range between 6-24) and 78.4 records (range between 20-110) detected each month. In general, neither the number of records nor the number of species were associated with individual climate variables, but multiple regression analyses showed that a combination of the accumulated precipitation of the four days before sampling and the average relative humidity can explain most of the fruiting dynamics (R2 = 0.56). When the ONI index was included in the analyses, the explained variability increased (R2 = 0.64), and when a categorization of months based on the same index was used, analyses showed that both the number of records and species evenness were affected by ENSO. At the species level, Hemitrichia calyculata was the only species observed during every month, closely followed by Arcyria cinerea, A. denudata, and Physarum compressum, recorded on most visits. Sporadic fruiting in some species such as Tubifera microsperma, P. tenerum, P. bogoriense, P. melleum, and Metatrichia vesparia could have been associated with local climate oscillations influenced by ENSO patterns. Phenological patterns were observed at the species level, indicating that in the Neotropics, under favorable conditions, myxomycete sporocarps are practically always present, but species assemblages vary temporally. These variations are primarily driven by local climate, but regional climate dynamics also affect fruiting patterns. Presumably, the remaining ecological effect on fruiting patterns in the Neotropics can be attributed to certain finer factors such as ecosystem structure, substrate quality/ availability, and biotic interactions. As such, phenomena such as climate change can have an important effect on the production of sporocarps by tropical myxomycetes, with subsequent effects of their ecological dynamics.
