Reported today in the journal Mycologia, the new finds include two new species named after movements in Mozart's Requiem.
A new luminescent fungus, Mycena silvaelucens, discovered by San Francisco State University Professor Dennis Desjardin and former SF State graduate student Brian Perry has been reported in the journal Mycologia. The species was collected in the grounds of an Orangutan Rehabilitation Center in Borneo, Malaysia and was found on the bark of a standing tree. The mushrooms are tiny with each cap measuring less than 18 millimeters in diameter. Credit: Brian Perry, University of Hawaii
The discoveries also shed light on the evolution of luminescence, adding to the number of known lineages in the fungi 'family tree' where luminescence has been reported.
San Francisco State University Biology Professor Dennis Desjardin and colleagues discovered the fungi in Belize, Brazil, Dominican Republic, Jamaica, Japan, Malaysia and Puerto Rico. The discoveries include four species new to science and three new reports of luminescence in known species.
Three quarters of glowing mushrooms, including the species described in the study, belong to the Mycena genus, a group of mushrooms that feed off and decompose organic matter as a source of nutrients to sustain their growth.
"What interests us is that within Mycena, the luminescent species come from 16 different lineages, which suggests that luminescence evolved at a single point and some species later lost the ability to glow," said Desjardin, lead author of the study. He believes that some fungi glow in order to attract nocturnal animals that aid in the dispersal of the mushroom's spores which are similar to seeds and are capable of growing into new organisms.
"It's pretty unusual to find this many luminescent species, typically only two to five percent of the species we collect in the field glow," Desjardin said. "I'm certain there are more out there."
The newly discovered fungi glow constantly, emitting a bright, yellowish-green light, and are tiny, with caps smaller than one centimeter across.
Desjardin has named two of the new species Mycena luxaeterna (eternal light) and Mycena luxperpetua (perpetual light), names inspired by Mozart's Requiem and the fact that these mushrooms glow 24 hours a day. To date, Desjardin has discovered more than 200 new fungi species and together with these latest findings, has discovered nearly a quarter of all known luminescent fungi.
"Luminescent Mycena: new and noteworthy species" was published online in the journal Mycologia on Oct. 5 and will appear in the March/April 2010 print issue. Co-authors include Brian A. Perry, former graduate student at San Francisco State University and currently of the University of Hawaii, D. Jean Lodge of the U.S. Forest Service, Cassius V. Stevani of the University of Sao Paulo, Brazil and Eiji Nagasawa of the Tottori Mycological Institute, Japan.

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...

The efficiency of power electronic systems is not solely dependent on electrical efficiency but also on weight, for example, in mobile systems. When the weight of relevant components and devices in airplanes, for instance, is reduced, fuel savings can be achieved and correspondingly greenhouse gas emissions decreased. New materials and components based on gallium nitride (GaN) can help to reduce weight and increase the efficiency. With these new materials, power electronic switches can be operated at higher switching frequency, resulting in higher power density and lower material costs.
Researchers at the Fraunhofer Institute for Solar Energy Systems ISE together with partners have investigated how these materials can be used to make power...
