Second bioluminescence‐activating component in the luminous fungus Mycena chlorophos

Mycena chlorophos is an oxygen‐dependent bioluminescent fungus. The mechanisms underlying its light emission are unknown. A component that increased the bioluminescence intensity of the immature living gills of M. chlorophos was isolated from mature M. chlorophos gills and chemically characterized. The bioluminescence‐activating component was found to be trans‐3,4‐dihydroxycinnamic acid and its bioluminescence activation was highly structure‐specific. ¹³C‐ and ¹⁸O‐labelling studies using the immature living gills showed that trans‐3,4‐dihydroxycinnamic acid was synthesized from trans‐4‐hydroxycinnamic acid in the gills by hydroxylation with molecular oxygen as well as by the general metabolism, and trans‐3,4‐dihydroxycinnamic acid did not produce hispidin (detection‐limit concentration: 10 pmol/1 g wet gill). Addition of 0.01 mM hispidin to the immature living gills generated no bioluminescence activation. These results suggested that the prompt bioluminescence activation resulting from addition of trans‐3,4‐dihydroxycinnamic acid could not be attributed to the generation of hispidin.

Identification of possible light emitters in the gills of a bioluminescent fungus Mycena chlorophos

The pileus of Mycena chlorophos actively, spontaneously, and continuously emits green light. Molecular mechanisms underlying this bioluminescence remain unclear. We investigated light emitters in the pileus of M. chlorophos to determine the underlying mechanisms. High‐performance liquid chromatography–fluorescence–photodiode array–mass detection analyses showed that actively luminescent gills in the pileus exclusively and abundantly possessed riboflavin, riboflavin 5′‐monophosphate, and flavin adenine dinucleotide as green‐fluorescent components. These components were localized in the bioluminescent region of the gills at the microscopic level. Fluorescence spectra of these green‐fluorescent components and the gills were identical with the spectrum of gill bioluminescence (maximum emission wavelength, 525 nm). Thus, our results indicated that the possible light emitters in the pileus of M. chlorophos were riboflavin, riboflavin 5′‐monophosphate, and/or flavin adenine dinucleotide.

Two new species of <Emphasis Type="Italic">Mycena</Emphasis> from alpine sites in Norway

Mycena aphanes and Mycena exilis, belonging to section Filipedes and section Polyadelphia, are proposed as new species. They are described and illustrated and compared to other species in the two sections. Mycena aphanes is a strikingly characteristic Mycena with fulvous or yellowish brown colours of both pileus and stipe. Mycena exilis is characterized by its occurrence on fallen Salix leaves, a pale brown pileus, occasionally with a pale pink tinge, narrowly adnate lamellae, four-spored basidia, and the presence of clamp connections.

Fruit-body production of a luminous mushroom,Mycena chlorophos

Cultural conditions for fruit-body production ofMycena chlorophos were investigated with the aim of using the mushroom for study of bioluminescence, scientific exhibition, and ecological conservation. A small glass jar having a cap with a microfilter was used as a culture vessel. A compost powder mixed with rice bran in proportion of 20% (fw/fw) and adjusted to 70% (w/w) in moisture content was used as production medium. Casing with 2 g/jar of moistened compost powder was necessary for fruit-body formation. Mycelium was grown in a culture chamber at 27°C, relative humidity (RH) of 80% for 4 wk, then transfered to a culture chamberat 21°C, 90% RH and light intensity of 300–800 lx after casing its, and incubated for 3 wk to produce fruit-bodies. The mean yield was 31 fruitbodies, i.e., 150 mg dry weight per jar.
