Question: Know Your Mushrooms and Gunner Palace are examples of what type of film making?
Context: Michael Tucker, an American documentary film director, was born in Honolulu, Hawaii.  He is best known for his recent documentary "".  He also directed a documentary in Iraq during the 2003 Iraqi War entitled "Gunner Palace". Shiitake mushroom dermatitis (also known as "Flagellate mushroom dermatitis," "Mushroom worker's disease," and "Shiitake-induced toxicoderma") is an intensely pruritic dermatitis characterized by disseminated 1mm erythematous micropapules seen in a linear grouped arrangement secondary to Koebnerization due to patient scratching.  It is caused by the ingestion of shiitake mushrooms and was first described in 1977 by Nakamura.  Although it is rarely seen outside of China and Japan due to a lower incidence of shiitake consumption outside these regions, there is a well-established association between flagellate dermatitis and shiitake mushroom (Lentinula edodes) ingestion.  Bleomycin ingestion may also cause similar findings.  On physical exam, one key difference between the two is that post-inflammatory hyperpigmentation changes are usually seen with bleomycin-induced flagellate dermatitis and are not typically present with shiitake mushroom induced flagellate dermatitis.  The median time of onset from ingestion of shiitake mushrooms is typically 24 hours, ranging from 12 hours to 5 days.  Most patients completely recover by 3 weeks, with or without treatment.  Although the pathogenesis of shiitake induced flagellate dermatitis is not clear, the theory most argued for is a toxic reaction to lentinan, a polysaccharide isolated from shiitake mushrooms. However, Type I and Type IV allergic hypersensitivities have also been supported by the 24-hour median time of onset, clearance in 3–21 days, severe pruritus, benefit of steroids and antihistamines, and lack of grouped outbreaks in people exposed to shared meals containing shiitake mushrooms. Most cases reported shortly after its discovery were due to consumption of raw shiitake mushrooms, but several cases have since been reported after consumption of fully cooked mushrooms. The Master Gunner St James’s Park’s appointment goes back to 1678 and has generally been held by a senior officer in the Royal Regiment.  The early incumbents (known then as the Master Gunner of Whitehall & St James's Park) were responsible for the artillery defence of Whitehall Palace and the Palace of Westminster. Know Your Mushrooms is a 2008 documentary film by Canadian director Ron Mann. Gunner Palace is a 2004 documentary film by Michael Tucker, which had a limited release in the United States on March 4, 2005.  The film was an account of the complex realities of the situation in Iraq during 2003–2004 amidst the Iraqi insurgency not seen on the nightly news.  Told first-hand by American troops stationed in the middle of Baghdad, "Gunner Palace" presents a portrait of a dangerous and chaotic war. Mycena galericulata is a mushroom species commonly known as the common bonnet, the toque mycena, or the rosy-gill fairy helmet.  The type species of the genus "Mycena" was first described scientifically in 1772, but was not considered a "Mycena" until 1821.  It is quite variable in color, size, and shape, which makes it somewhat difficult to reliably identify in the field.  The mushrooms have caps with distinct radial grooves, particularly at the margin.  The cap's color varies from grayish brown to dark brown and the shape ranges from bell-like to bluntly conical to flattened with an umbo.  The stem is hollow, white, tough and thin, without a ring and often roots deeply into the wood on which it grows.  The gills are white to grayish or even pinkish when mature and are connected by distinct cross-veins.  The caps can reach 4 cm in diameter, and have a mealy odor and taste.  The spore print is white and the gills are pink at maturity, which can lead to possible confusion with species of the "Pluteus" genus.  "M. galericulata" mushrooms grow mostly in clusters on the well-decayed stumps of deciduous and coniferous trees from spring to autumn.  The species can generally be considered inedible.  It is common and widespread in the entire temperate zone of the Northern Hemisphere, but it has also been reported from Africa. The Chicago film industry is a central hub for motion picture production and exhibition that was established before Hollywood became the undisputed capital of film making.  In the early 1900s, Chicago boasted the greatest number of production companies and filmmakers.  Essanay Studios founded by George K. Spoor was one of the earliest successful studios to produce movies in Chicago, employing stars such as Charlie Chaplin and Gloria Swanson.  Actor and co-founder of Essanay Studios "Broncho Billie" Anderson gave birth to the western genre.  Early film companies such as Essanay Studios produced multiple silent films every week and rented viewing equipment to showcase the latest cinematography to the public.  This rental culture gave birth to the popularity of Nickelodeons up until the Great Depression.  However, due to the high demand for motion pictures during this time, a black market for films and equipment developed.  The Motion Picture Patents Company, established in 1909 as a conglomerate of the major studios, sought to eliminate all illegal use of patented film equipment.  As a result, independent ventures entered the film scene.  Independents drove the film industry to the west to avoid legal trouble with the trust of major film companies united under the Motion Picture Patents Company.  The west offered fairer weather and scenery that better accommodated film making.  Not until the 1980s and early 21st century has Chicago experienced a film production revival.  Blockbusters, such as "Blues Brothers", "Sixteen Candles", and "The Dark Knight", have rejuvenated the Chicago film scene.  In the 21st century, Chicago further experienced a film revival due to a tax bill the state of Illinois passed to give filmmakers a 30% tax break on production costs. A tail gunner or rear gunner is a crewman on a military aircraft who functions as a gunner defending against enemy fighter attacks from the rear, or "tail", of the plane.  The tail gunner operates a flexible machine gun emplacement in the tail end of the aircraft with an unobstructed view toward the rear of the aircraft.  While the term tail gunner is usually associated with a crewman inside a gun turret, the first tail guns were operated from open apertures within the aircraft's fuselage, like in the Scarff ring mechanism used in the British Handley Page V/1500 (a 1918 aircraft), and also, in the most evolved variants of this type of air-to-air anti-aircraft defense, they may also be operated by remote control from another part of the aircraft, like in the American B-52 bombers (an aircraft first introduced in 1955 but still in service). "beta"-Amanitin or β-amanitin is a cyclic peptide comprising eight amino acids.  It is part of a group of toxins called amatoxins, which can be found in several mushrooms belonging to the "Amanita" genus.  Some examples are the Death cap ("Amanita phalloides") and members of the Destroying angel complex, which includes "A. virosa" and "A. bisporigera".  Due to the presence of α-amanitin, β-amanitin, γ-amanitin and ε-amanitin these mushrooms are highly lethal to human beings.
