Description
Properties
Panellus stipticus is a species of mushroom in the genus Panellus. Other names for this mushroom are bitter clam mushroom, bitter sharp dwarf gnocchi, or oak dwarf gnocchi.
Panellus stipticus is a saprobiontic colonizer of old logs, stumps and lying branches, causing brown rot in the colonized wood. It prefers oaks and copper beech as substrates, but may also occur on a number of other hardwoods, rarely on conifers. The species occurs, as far as suitable substrate is available, in almost all forest types, in parks, gardens in tree rows and on solitary trees.
The Bitter Oyster Mushroom is unsuitable as an edible fungus, and it is not of forestry importance as a wood destroyer.
The chemical structure of the two #luciferin precursors PS-A and PS-B isolated from the fungus Panellus stipticus was determined to be 1-O-decanoylpanal and 1-O-dodecanoylpanal.
Both PS-A and PS-B were converted to chemiluminescent luciferins by treatment with 50 mmol/L methylamine in a buffer solution with a pH of 3.5 containing the anionic surfactant tergitol 4 at 25-35°C. Lucifer ins emitted chemiluminescence in a buffer solution with a pH of 7-8 containing a cationic surfactant in the presence of O2.
This means that they can glow
