The lignicolous saprotrophic genus Entonaema contains six formally accepted species: E. liquescens (type species), E. cinnabarinum, E. globosum, E. dengii, E. moluccanum, and E. siamensis. Its ...stromatic ascomata develop on the surface of dead wood remnants; they are rather large, globose to irregularly shaped, and vividly coloured. The fresh stroma interior is filled with a liquid matter. In early studies, the genus was considered to have a preference for tropical habitats, while in more recent field research, numerous collections have been added from warm, temperate areas of Europe, North America, and Asia. Our taxonomic and phylogenetic studies were based on freshly collected E. cinnabarinum from Croatia and E. liquescens from the USA. A phylogenetic study of the sequence alignment of four concatenated gene regions (ITS, LSU, rpb2, and β-tub) revealed the true taxonomic position of Entonaema within Hypoxylaceae (Xylariales), a sister to Hypoxylon carneum. Detailed macroscopic and microscopic descriptions of E. cinnabarinum are accompanied by drawings and colour photographs, while the study of E. liquescens is focused on stromatal microchemical reaction. With new information, the worldwide identification key to the putative species of Entonaema is proposed. Ecological data and biogeographical patterns were studied using all available and reliable sources of recorded data. Climatic preferences of the two most widespread Entonaema species, E. liquescens and E. cinnabarinum, are discussed in detail.
Recent publications have argued that there are potentially serious consequences for researchers in recognising distinct genera in the terminal fusarioid clade of the family Nectriaceae. Thus, an ...alternate hypothesis, namely a very broad concept of the genus Fusarium was proposed. In doing so, however, a significant body of data that supports distinct genera in Nectriaceae based on morphology, biology, and phylogeny is disregarded. A DNA phylogeny based on 19 orthologous protein-coding genes was presented to support a very broad concept of Fusarium at the F1 node in Nectriaceae. Here, we demonstrate that re-analyses of this dataset show that all 19 genes support the F3 node that represents Fusarium sensu stricto as defined by F. sambucinum (sexual morph synonym Gibberella pulicaris). The backbone of the phylogeny is resolved by the concatenated alignment, but only six of the 19 genes fully support the F1 node, representing the broad circumscription of Fusarium. Furthermore, a re-analysis of the concatenated dataset revealed alternate topologies in different phylogenetic algorithms, highlighting the deep divergence and unresolved placement of various Nectriaceae lineages proposed as members of Fusarium. Species of Fusarium s. str. are characterised by Gibberella sexual morphs, asexual morphs with thin- or thick-walled macroconidia that have variously shaped apical and basal cells, and trichothecene mycotoxin production, which separates them from other fusarioid genera. Here we show that the Wollenweber concept of Fusarium presently accounts for 20 segregate genera with clear-cut synapomorphic traits, and that fusarioid macroconidia represent a character that has been gained or lost multiple times throughout Nectriaceae. Thus, the very broad circumscription of Fusarium is blurry and without apparent synapomorphies, and does not include all genera with fusarium-like macroconidia, which are spread throughout Nectriaceae (e.g., Cosmosporella, Macroconia, Microcera). In this study four new genera are introduced, along with 18 new species and 16 new combinations. These names convey information about relationships, morphology, and ecological preference that would otherwise be lost in a broader definition of Fusarium. To assist users to correctly identify fusarioid genera and species, we introduce a new online identification database, Fusarioid-ID, accessible at www.fusarium.org. The database comprises partial sequences from multiple genes commonly used to identify fusarioid taxa (act1, CaM, his3, rpb1, rpb2, tef1, tub2, ITS, and LSU). In this paper, we also present a nomenclator of names that have been introduced in Fusarium up to January 2021 as well as their current status, types, and diagnostic DNA barcode data. In this study, researchers from 46 countries, representing taxonomists, plant pathologists, medical mycologists, quarantine officials, regulatory agencies, and students, strongly support the application and use of a more precisely delimited Fusarium (= Gibberella) concept to accommodate taxa from the robust monophyletic node F3 on the basis of a well-defined and unique combination of morphological and biochemical features. This F3 node includes, among others, species of the F. fujikuroi, F. incarnatum-equiseti, F. oxysporum, and F. sambucinum species complexes, but not species of Bisifusarium F. dimerum species complex (SC), Cyanonectria (F. buxicola SC), Geejayessia (F. staphyleae SC), Neocosmospora (F. solani SC) or Rectifusarium (F. ventricosum SC). The present study represents the first step to generating a new online monograph of Fusarium and allied fusarioid genera (www.fusarium.org).

Seventeen collections of the genus Parasola from Croatia were studied with integrative taxonomic methods. Parasola papillatospora is described as a new species, based on morphology and multigene ...phylogenetic analyses. Its basidiomata were growing on soil in temperate deciduous forests (Quercus petraea, Fagus sylvatica, and Carpinus betulus) on two different localities in NW Croatia. Based on publicly available molecular data, the species is also recorded in Hungary. The most distinctive morphological features of the new species are the characteristics of its basidiospores, (1) the papillate apex and (2) central germ pore (both present in most spores), as well as (3) a highly variable shape. A morphological description of P. papillatospora is accompanied by colour photographs of basidiomata, basidiospores, and cystidia. In this study, a total of 64 DNA sequences from 17 specimens belonging to 10 Parasola species were newly generated. As a result of Bayesian Inference and Maximum Likelihood phylogenetic analyses of the concatenated ITS, LSU, tef-1α, and β-tub gene alignment of Parasola species, P. papillatospora was resolved as an independent clade, a sister to the clade comprising the P. plicatilis species complex. Eight Parasola species (P. auricoma, P. crataegi, P. cuniculorum, P. kuehneri, P. malakandensis, P. megasperma, P. nudiceps, P. plicatilis-similis) are reported for the first time for Croatia and P. malakandensis also for Europe. Colour photographs of basidiomata are provided for all Parasola species new to Croatia except P. kuehneri.

Integrative taxonomic studies of macrofungal diversity in the Brijuni National Park (Istria County, Croatia) led to the discovery of a second species of Inocybe (Agaricales, Inocybaceae) new to ...science. Inocybe istriaca sp. nov. is described on the basis of morphological, ecological, and multigene phylogenetic analyses, and its placement within the family Inocybaceae is discussed. The combination of most important morphological characters that distinguish I. istriaca from the other similar Inocybe species are smooth, (sub)amygdaliform, (sub)phaseoliform, or ellipsoid basidiospores (ca. 8.5–12 × 5–7 μm), large basidia (36–45 × 9–15 μm), mostly (sub)fusiform and weakly thick-walled (up to 1.5 μm) metuloid pleurocystidia, and lamellar edge and stipe apex partially covered by a dark resinous substance. The species was collected on the edge of grassland and Mediterranean evergreen holm oak (Quercus ilex) forest. In this study, a total of 14 DNA sequences from four Inocybe species were generated. Two-gene (ITS, LSU) and four-gene (ITS, LSU, rpb2, tef1) phylogenetic analyses confirmed the status of I. istriaca as an independent species.
Closed cleistothecia-like ascomata have repeatedly evolved in non-related perithecioid and apothecioid lineages of lichenized and non-lichenized
. The evolution of a closed, darkly pigmented ascoma ...that protects asci and ascospores is conceived as either an adaptation to harsh environmental conditions or a specialized dispersal strategy. Species with closed ascomata have mostly lost sterile hymenial elements (paraphyses) and the capacity to actively discharge ascospores. The class
, one of the most speciose classes of
, is mainly apothecioid, paraphysate, and possesses active ascospore discharge. Lineages with closed ascomata, and their morphological variants, have evolved independently in several families, such as
,
,
, etc.
is a distinctive order in the
class. It has two widespread families (
,
) with mostly closed ascomata, evanescent asci, and thus passively dispersed ascospores. Within the order, closed ascomata dominate and a great diversity of peridia have evolved as adaptations to different dispersal strategies. The type genus,
, is an exceptional case of ascomatal evolution within the order. Its species are the most diverse in functional traits, encompassing species with closed ascomata and evanescent asci, and species with open ascomata, active ascospore discharge, and paraphyses. Open ascomata were previously suggested as the ancestral state in the genus, these ascomata depend on mammals and birds as dispersal agents. In this scheme, species with closed ascomata, a lack of paraphyses, and passive ascospore discharge exhibit derived traits that evolved in adaptation to cold ecosystems. Here, we used morphological and phylogenetic methods, as well as the reconstruction of ancestral traits for ascomatal type, asci dehiscence, the presence or absence of paraphyses, and ascospore features to explore evolution within
. We demonstrate the apothecial ancestry in
and propose a new hypothesis about the evolution of the open ascomata in
, involving a process of re-evolution where the active dispersal of ascospores appears independently twice within the order. We propose a new family,
, within
, that retains the phenotypic features exhibited by species of
, i.e., pigmented capitate paraphyses and active asci discharge with an opening limitation ring.
