SIG on Phyllachorales (Program) (Abstracts) – Jose C. Dianese

The Phyllachorales consist of a major group of tropical and subtropical plant pathogens until recently with a precarious situation in terms of its taxonomy and phylogenetic relations. Recent publications indicate a new trend that will lead to an overall clearer picture that, however, need to be further exposed and discussed due to ambiguities that remain to be solved. Thus, just for the genus Phyllachora over 1500 records are shown by Index Fungorum, with an absolutely small number connected to some molecular knowledge. Thus a Symposium dealing with Phyllachorales and related orders, constitutes a very attractive theme that will for sure motivate a large group of mycologists involved with biotrophic plant parasitic fungi, especially important all over the Tropical areas of the world.

International Flammulina community – A.F. van Peer

Flammulina velutipes is a popular edible mushroom (largely in South East Asia) with supposed health benefits and medicinal value. It is also emerging as one of the model species for studies on edible mushrooms. The genome has been sequenced and published, it is massively cultivated, it is genetically accessible, and it is studied in many countries on various topics. However, communication between industry and researchers on Flammulina is very limited. To improve communication, an International Flammulina Community was held at Fujian Agriculture and Forestry University in November 2015. The idea is to continue to promote our community (~60 members by now) through a website (under construction), and through satellite meetings. Normally, researchers do not have much budget to attend international meetings focused on a single species, and it is difficult to gather them. The IMC meeting would be an excellent venue for such a satellite (special interest group) meeting on Flammulina species. It will allow anyone who attends IMC to get to know our community, to be updated on the latest developments on F. velutipes research (and production), and to share ideas about improving the community platform.

 

Taxonomy of the LeotiomycetesPeter Johnston

The Leotiomycetes constitute a large group of Ascomycota that has not been fully studied. The group is diversed in ecology and morphology. Molecular studies have been limited. We invite interested parties to join this informal discussion to address

1) sampling within this group

2) progress on barcoding specimens

3) determination of important and critical genera for inclusion in studies

4) use of epitypes and reliance on type studies to stabilize the classification

5) genome-scale phylogenies

The intent is to introduce workers with brief comments on projects undertaken. To solve the taxonomy and to stabilize higher level classification the advisability of establishing a formal working group or ICTF Subcommision will be discussed.

 

ICTF DNA Taxonomy Debate Session – Keith Seifert, Andrew Miller

“Should DNA sequences be allowed as the sole identifying criterion for naming species?”

DNA as type refers to the naming of taxa based solely on DNA sequences with no corresponding voucher specimen. Although this is not accepted in the current ICN, mycologists have found creative ways to circumvent this and several new species have been described based on a published illustration of the DNA sequence. This opens the door for literally millions of new fungal taxa being described based on short stretches of environmental sequences. The intention of the ICTF is to provide a venue of discussion for a wider range of fungal taxonomists who have not participated up to this point. This debate-style session will explore the advantages and disadvantages of adopting an article for DNA sequence as type in the Code. The first 10 minutes will be dedicated to introducing the topic, clarifying the question(s) being debated, and establishing the ground rules for the debate and discussion. Each member of each 3-person panel for and against the issue will have 3 minutes to discuss their opinions. The remaining 60 minutes will be for open discussion from the audience with a limit of 3 minutes per person.
