Rhizomarasmius
''Rhizomarasmius'' is a genus of fungi in the family Physalacriaceae, containing about five species. General The genus was created in 2000 by R. H. Petersen to accommodate two species then classified in Marasmius (''M. pyrrhocephalus'' and ''M. undatus''), but which do not belong there due to morphological grounds, including the nature of the cystidia and the way the mushrooms are rooted on a plant substrate. This analysis was backed up in 2006 by DNA comparisons done by Wilson and Desjardin. Unlike most ''Marasmius'' mushrooms, members of ''Rhizomarasmius'' grow on the rhizomes of ferns or flowering plants, and that is the signification of the genus name. Instead of the Marasmiaceae this genus is placed in the Physalacriaceae, a sister clade but a separate family.

Rhizomarasmius Undatus
''Rhizomarasmius undatus'' ( syn. ''Marasmius undatus'') is a small mushroom which grows on fern rhizomes. Description The species can be described as follows: *The cap has a powdery covering (a pruina), is initially whitish and convex and later becomes brownish grey and expands to be flat. It grows to about 2.5 cm in diameter. *The gills are whitish and distant, and broadly adnate to the stem, or slightly decurrent. The spore powder is white. *The rigid stem can grow to about 12 cm long by about 2 mm in diameter. It is white at the top and dark brown to black lower down, with a puinose covering of short white hairs. *The smell and taste are not distinctive. *The spores are lemon-shaped to ellipsoid and measure roughly 9-12 µm x 5-7 µm. Naming and related species The species epithet ''undatus'', meaning "wavy", is the past participle of the Latin verb "undo" (= "I undulate"). This species was originally described in 1836 as ''Agaricus undatus'' b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhizomarasmius Setosus
''Rhizomarasmius setosus'' ( syn. ''Marasmius setosus'' or ''Marasmius recubans'') is a tiny whitish mushroom having a distinctive hairy stem. It has been given the vernacular name "Beechleaf Parachute". Description The species can be described as follows: *The white cap is initially hemispherical and later flat. It grows to about 0.5 cm in diameter. *The gills are white and distant, and either adnate or somewhat decurrent.

Rhizomarasmius Epidryas
''Rhizomarasmius epidryas'' ( syn. ''Marasmius epidryas'' or ''Mycetinis epidryas'') is one of a group of mushrooms formerly in the genus ''Marasmius''. It grows amongst dwarf shrubs of the genus ''Dryas'' in arctic or high mountain environments. Description The species can be described as follows: *The cap is brownish yellow and grows to about 1 cm in diameter. *The gills are white and fairly distant, and broadly attached to the stem. The spore powder is white. *The stem can grow to 4 cm tall by up to 2 mm in diameter, being broader at the apex. It is brown above and blackish brown at the base, with a velvety covering of hairs. *The smell and taste are not distinctive. *The spores are roughly ellipsoid or almond-shaped and measure roughly 8.5-10.5 µm x 5-7 µm.

Physalacriaceae
The Physalacriaceae are a family of fungi in the order Agaricales. Species in the family have a widespread distribution, ranging from the Arctic, ('' Rhizomarasmius''), to the tropics, e.g. '' Gloiocephala'', and from marine sites ('' Mycaureola'') and fresh waters ('' Gloiocephala'') to semiarid forests ('' Xerula''). Description Most species in the Physalacriaceae form fruit bodies with caps and stipes. They have a monomitic hyphal system (wherein only generative hypha are produced), and clamp connections are present in the hyphae. Basidia (spore-bearing cells) are club-shaped with two to four sterigmata. The basidiospores generally have ellipsoidal, spindle-like (fusiform), cylindrical, or tear-drop (lacrimiform) shapes; they are thin-walled, hyaline, and do not react with Melzer's reagent. The family also contains corticioid fungi (in genus '' Cylindrobasidium'') and a secotioid species ('' Guyanagaster necrorhiza''). Taxonomy The family was originally defined by Englis ...

Marasmius Setosus A2 Detail
''Marasmius'' is a genus of mushroom-forming fungi in the family Marasmiaceae. It contains about 500 species of agarics, of which a few, such as ''Marasmius oreades'', are edible. However, most members of this genus are small, unimpressive brown mushrooms. Their humble appearance contributes to their not being readily distinguishable to non-specialists, and they are therefore seldom collected by mushroom hunters. Several of the species are known to grow in the characteristic fairy ring pattern. The author of the genus was Elias Magnus Fries, who in 1838 classified white-spored agarics having a tough central stipe in this taxon if they were marcescent, i.e. they could dry out but later revive when moistened. For Fries, marcescence — by contrast with the " putrescent" (decomposing) nature of most mushrooms — was an important character for classification, which he used to separate this group from genus ''Collybia'' (which has now been split into many newer gener ...

Mycotaxon
''Mycotaxon'' is a peer-reviewed scientific journal that covers the nomenclature and taxonomy of fungi, including lichens. The journal was founded by Grégoire L. Hennebert and Richard P. Korf in 1974. They were frustrated that papers submitted to journals such as ''Mycologia'' took a year or longer from submission to publication. Korf and Hennebert introduced a number of innovations to make their journal more efficient and accessible than its contemporaries. ''Mycotaxon'' reduced the wait time between submission and publication by requiring authors to submit camera-ready copy. Linotype was the industry standard at the time; ''Mycotaxon'' used photo-offset lithography Lithography () is a planographic method of printing originally based on the immiscibility of oil and water. The printing is from a stone (lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German a ... to expedite publication.
