Input (English): Context: The Mycenaceae are a family of fungi in the order Agaricales. According to the "Dictionary of the Fungi" (10th edition, 2008), the family contains 10 genera and 705 species. This is one of several families that were separated from the Tricholomataceae as a result of phylogenetic analyses. Taxa in the Mycenaceae are saprobic, have a cosmopolitan distribution, and are found in almost all ecological zones. The family was circumscribed by Caspar van Overeem in 1926., Mycena rosea , commonly known as the rosy bonnet , is a species of mushroom in the Mycenaceae family . First named Agaricus roseus in 1803 by Danish botanist Heinrich Christian Friedrich Schumacher , it was given its present name in 1912 by Gramberg ., The Tricholomataceae are a large family of mushrooms within the Agaricales. A classic "wastebasket taxon", the family is inclusive of any white-, yellow-, or pink-spored genera in the Agaricales not already classified as belonging to the Amanitaceae, Lepiotaceae, Hygrophoraceae, Pluteaceae, or Entolomataceae. , Mycena is a large genus of small saprotrophic mushrooms that are rarely more than a few centimeters in width. They are characterized by a white spore print, a small conical or bell-shaped cap, and a thin fragile stem. Most are gray or brown, but a few species have brighter colors. Most have a translucent and striate cap, which rarely has an incurved margin. The gills are attached and usually have cystidia. Some species, like "Mycena haematopus", exude a latex when the stem is broken, and many species have a chlorine-like odor. , Subject: mycena rosea, Relation: spore_print_color, Options: (A) brown (B) white
