Abstract: Diversity of corticioid fungi (resupinate Basidiomycota), especially outside the northern temperate climatic zone, remains poorly explored. Furthermore, most of the known species are delimited by morphological concepts only and, not rarely, these concepts are too broad and need to be tested by molecular tools. For many decades, the delimitation of species in the genus Subulicystidium (Hydnodontaceae, Trechisporales) was a challenge for mycologists. The presence of numerous transitional forms as to basidiospore size and shape hindered species delimitation and almost no data on molecular diversity have been available. In this study, an extensive set of 144 Subulicystidium specimens from Paleo- and Neotropics was examined. Forty-nine sequences of ITS nuclear ribosomal DNA region and 51 sequences of 28S nuclear ribosomal DNA region from fruit bodies of Subulicystidium were obtained and analysed within the barcoding gap framework and with phylogenetic Bayesian and Maximum likelihood approaches. Eleven new species of Subulicystidium are described based on morphology and molecular analyses: Subulicystidium boidinii, S. fusisporum, S. grandisporum, S. harpagum, S. inornatum, S. oberwinkleri, S. parvisporum, S. rarocrystallinum, S. robustius, S. ryvardenii and S. tedersooi. Morphological and DNA-evidenced borders were revised for the five previously known species: S. naviculatum, S. nikau, S. obtusisporum, S. brachysporum and S. meridense. Species-level variation in basidiospore size and shape was estimated based on systematic measurements of 2840 spores from 67 sequenced specimens. An updated identification key to all known species of Subulicystidium is provided.

Annotating public fungal ITS sequences from the built environment according to the MIxS-Built Environment standard – a report from a May 23-24, 2016 workshop (Gothenburg, Sweden) https://mycokeys.pensoft.net/article/10000/ MycoKeys 16: 1-15

Abstract: Recent molecular studies have identified substantial fungal diversity in indoor environments. Fungi and fungal particles have been linked to a range of potentially unwanted effects in the built environment, including asthma, decay of building materials, and food spoilage. The study of the built mycobiome is hampered by a number of constraints, one of which is the poor state of the metadata annotation of fungal DNA sequences from the built environment in public databases. In order to enable precise interrogation of such data – for example, “retrieve all fungal sequences recovered from bathrooms” – a workshop was organized at the University of Gothenburg (May 23-24, 2016) to annotate public fungal barcode (ITS) sequences according to the MIxS-Built Environment annotation standard (http://gensc.org/mixs/). The 36 participants assembled a total of 45,488 data points from the published literature, including the addition of 8,430 instances of countries of collection from a total of 83 countries, 5,801 instances of building types, and 3,876 instances of surface-air contaminants. The results were implemented in the UNITE database for molecular identification of fungi (http://unite.ut.ee) and were shared with other online resources. Data obtained from human/animal pathogenic fungi will furthermore be verified on culture based metadata for subsequent inclusion in the ISHAM-ITS database (http://its.mycologylab.org).

LIAS light – Towards the ten thousand species milestone https://mycokeys.pensoft.net/article/1203/ MycoKeys 8: 11-16

DOI: 10.3897/mycokeys.8.6605

Authors: Gerhard Rambold, John A. Elix, Bärbel Heindl-Tenhunen, Thomas Köhler, Thomas H. Nash III, Dieter Neubacher, Wolfgang Reichert, Luciana Zedda, Dagmar Triebel

Abstract: Over the past 12 years, the lichen trait database LIAS light as a component of the LIAS information system, has grown to a considerable pool of descriptive data based on 71 different qualitative, quantitative, and text characters, for nearly 10.000 lichen taxa, being phylogenetically arranged according to the MycoNet classification. It includes information on morphological, ecological and chemical traits. Multilinguality or internationalization options have become a central challenge of the project. At present, 18 language versions of the database and web interface exist. LIAS light data are accessible in DELTA format and to be used locally and web browser-based, via NaviKey applet.
