The taxonomic position of slime moulds has baffled naturalists and scientists for centuries. When “the father of taxonomy” Swedish botanists Carl Linneus devised his system of classification he included slime moulds (and fungi) in the plant kingdom. Slime moulds were subsequently placed in various kingdoms but are now regarded as amoebozoans.

Sarah Lloyd has observed slime moulds in a eucalypt forest at Birralee Tasmania for 13 years. It is now considered a hotspot for myxomycetes, with over 120 species documented from the site including 4 hitherto undescribed species, one new genus and more new species awaiting further study. In this webinar Sarah will discuss these and also describe the important ecological roles of slime moulds.

Sarah Lloyd has had a lifelong love of birds, and since 1988 when she moved to live in a forest at Black Sugarloaf, Birralee in central north Tasmania, an interest in plants, bryophytes, fungi and slime moulds. She has contributed to several citizen science projects including the Australian Bird Count, and Fungimap, a project to record Australia’s undocumented fungal species. It was through Fungimap that Sarah was introduced to slime moulds. In 2019 she was awarded an OAM (Order of Australia medal) for “services to conservation – and slime moulds”. She is author of numerous books, including Where the Slime Moulds Creep (4th Edition, 2022).

We will present an overview of the taxonomy and distribution of the species of Pluteus in North America based on morphological studies and molecular phylogenies. A total of 120 taxa (species and varieties) of Pluteus have been described from or reported in North America, but currently only c. 40 of these species have been confirmed to occur here, based on molecular data generated from North American voucher collections. We will discuss the ongoing, collaborative projects to clarify the status of old names in the genus, and to describe a good number on new species, through a combination of morphological and molecular approaches and collaboration with citizen-scientists.

The Talk:  As humans reshape Earth's biodiversity, conservationists and the public worry about what will happen to animals and plants.  But what about fungi?  Mushrooms are also on the move, and movements are often mediated by commerce and trade.  Humans brought the fungus Amanita phalloides to California, and it is now invasive.  How did that happen and why is it spreading?

Damon Tighe is an amateur mycologist from Oakland California who is a big user of the iNaturalist platform. He is a collector for the California Fungal Diversity Survey (FUNDIS) and has done fungal surveys in Ecuador, Arizona, among other locales using iNaturalist as the primary tool to collect and share data with stakeholders. In his professional life he was a former researcher on the Human Genome Project and now helps translate biotechnology techniques into classroom activities for education institutions across the country.

In 1989, a standing forest in Finland was burnt for restoration purposes. It was a first in Finland - and perhaps in the whole of Europe. Collections of wood-decaying polypore fungi were studied on the burn site, beginning a year before the fire and continuing for 33 years after. It is likely that the number of species observed during the study period was a record for any one-hectare forest area in Finland. Several red-listed species were found and in general, the effects of burning appeared to have a positive effect on polypore diversity.

Kaisa Junninen works as a senior specialist on species conservation at Metsähallitus Parks & Wildlife Finland. She is a forest ecologist who has specialized in polypore fungi, deadwood ecology and natural forests, and has been in charge of red-listing polypore fungi in Finland. She is featured in Considering Fungi, Episode 1: Facilitating Habitat Formation in Boreal Forests

Since the MycoConsortium of the Northeast is filled with people that have great interest in fungi, this presentation will focus on some of the wonders of the fungal world that Bob has encountered over the past decades. These examples are in his top list of fungi that represent the extraordinary nature of the fungal kingdom – they are fungi with a WOW factor.

The Orbiliomycetes are a class of ascomycetes which belongs to the first which produced ascomata. It only includes one family, Orbiliaceae, with 10 genera and around […]
