Amanita muscaria, commonly known as the fly agaric, is a poisonous and psychoactive basidiomycete fungus, one of many in the genus Amanita. Native throughout the temperate and boreal regions of the Northern Hemisphere, Amanita muscaria has been unintentionally introduced to many countries in the Southern Hemisphere, generally as a symbiont with pine plantations, and is now a true cosmopolitan species. It associates with various deciduous and coniferous trees. The quintessential toadstool, it is a large white-gilled, white-spotted, usually deep red mushroom, one of the most recognizable and widely encountered in popular culture. 
The name destroying angel applies to several similar, closely related species of deadly all-white mushrooms in the genus Amanita. They are Amanita bisporigera and A. ocreata in eastern and western North America, and A. virosa in Europe... Closely related to the death cap (A. phalloides), they are among the most toxic known mushrooms, containing amatoxins as death caps do.

old fable, fairy tale
The National Socialist Movement in the Netherlands (Dutch: Nationaal-Socialistische Beweging in Nederland, NSB) was a Dutch fascist and later national socialist political party. As a parliamentary party participating in legislative elections, the NSB had some success during the 1930s. It remained the only legal party in the Netherlands during most of the Second World War.

"Hansel and Gretel" (German: Hänsel und Gretel, "Little John and Little Margaret") is a well-known fairy tale of German origin, recorded by the Brothers Grimm and published in 1812. Hansel and Gretel are a young brother and sister threatened by a cannibalistic witch living deep in the forest in a house constructed of cake and confectionery. The two children save their lives by outwitting her. The tale has been adapted to various media, most notably the opera Hänsel und Gretel (1893) by Engelbert Humperdinck and a stop-motion animated feature film made in the 1950s based on the opera. Under the Aarne-Thompson classification system, "Hansel and Gretel" is classified under Class 327, "The Children and the Ogre". 
Dutch resistance to the Nazi occupation of the Netherlands during World War II can be mainly characterized by its prominent non-violence, summitting in over 300,000 people in hiding in the fall of 1944, tended to by some 60,000 to 200.000 illegal landlords and caretakers and tolerated knowingly by some 1 million people, including German occupiers and military. 
The Supermarine Spitfire is a British single-seat fighter aircraft which was used by the Royal Air Force and many other Allied countries throughout the Second World War. The Spitfire continued to be used as a front line fighter and in secondary roles into the 1950s. It was produced in greater numbers than any other British aircraft, and was the only British fighter in production throughout the war. 
Anton Adriaan Mussert (May 11, 1894, Werkendam, North Brabant – May 7, 1946) was one of the founders of the National Socialist Movement (NSB) in the Netherlands and its de jure leader. As such, he was the most prominent national socialist in the Netherlands before and during the Second World War. During the war, he was able to keep this position, due to the support he received from the Germans. After the war, he was convicted and executed for high treason. 
Scheveningen is one of the eight districts of The Hague, as well as a subdistrict (wijk) of that city. Scheveningen is a modern seaside resort with a long sandy beach, an esplanade, a pier, and a lighthouse. The beach is popular for water sports such as windsurfing and kiteboarding. A nudist section is 1 km to the north. The harbor is used for both fishing and tourism. 
René Karl Wilhelm Johann Josef Maria Rilke (4 December 1875 – 29 December 1926), better known as Rainer Maria Rilke, was a Bohemian–Austrian poet. He is considered one of the most significant poets in the German language. His haunting images focus on the difficulty of communion with the ineffable in an age of disbelief, solitude, and profound anxiety: themes that tend to position him as a transitional figure between the traditional and the modernist poets. 
98.16 Young Rauhandel
A former friend of Blicero, probably a lover willing to indulge his sado-masochistic tastes. The name literally means "Rough Trade."
98.24 the Ufa-Theatre
Weisenburger’s information on UFA is essentially correct, but he misgives Georg Wilhelm Pabst’s first name as "Rudolf." One curiosity in Pynchon's German film references is the lack of any mention of F.W. Murnau, perhaps the greatest director of that era. His films Nosferatu (the first film version of Dracula) and Faust would seem to be natural allusions for Pynchon to use.
Universum Film AG, better known as UFA or Ufa, is a film company that was the principal film studio in Germany, home of the German film industry during the Weimar Republic and through World War II, and a major force in world cinema from 1917 to 1945. After World War II, UFA continued producing movies and television programmes to the present day, making it the longest standing film company in Germany. 
The Friedrichstraße (lit. Frederick Street) is a major culture and shopping street in central Berlin, forming the core of the Friedrichstadt neighborhood. It runs from the northern part of the old Mitte district (north of which it is called Chausseestraße) to the Hallesches Tor in the district of Kreuzberg. Due to its north-southerly direction, it forms important junctions with the east-western axes, most notably with Leipziger Straße and Unter den Linden.

The Duino Elegies (German Duineser Elegien) are a set of ten elegies written in German by the poet Rainer Maria Rilke from 1912 to 1922. Rilke had been visiting Princess Marie von Thurn und Taxis in the Duino castle near Trieste in January 1912 and, according to his own recounting, had taken a stroll near the castle, atop the steep cliffs that dropped down to the beach. Rilke said later he had heard a voice calling to him as he walked near the cliffs, and he had used its words as the opening... 
the great Herero Rising
The Herero and Namaqua Genocide is considered to have been the first genocide of the 20th century. It took place between 1904 and 1907 in German South-West Africa (modern day Namibia), during the scramble for Africa. On January 12, 1904, the Herero people, led by Samuel Maharero, rebelled against German colonial rule. In August, German general Lothar von Trotha defeated the Herero in the Battle of Waterberg and drove them into the desert of Omaheke, where most of them died of thirst. In October, the Nama people also rebelled against the Germans only to suffer a similar fate.

Rhenish Missionary Society
The Rhenish Missionary Society (Rhenish - of the river Rhine) was one of the largest missionary societies in Germany. Formed from smaller missions founded as far back as 1799, the Society was amalgamated on 23 September 1828, and its first missionaries were ordained and sent off to South Africa by the end of the year.

The Harz is the highest mountain range in northern Germany and its rugged terrain extends across parts of Lower Saxony, Saxony-Anhalt and Thuringia. The name Harz derives from the Middle High German word Hardt or Hart (mountain forest). The legendary Brocken is the highest summit in the Harz with a height of 1,141.1 metres (3,744 ft) above sea level. The Wurmberg (971 metres (3,186 ft)) is the highest peak located entirely within Lower Saxony. 
101.1-2 In Hoc Signo Vinces
Latin, "in this sign you will conquer.". According to legend Constantine the Great adopted this Greek phrase, "εν τούτω νίκα", after his vision of a chi and rho on the sky just before the Battle of the Milvian Bridge (312 CE). He had his men paint the chi rho on their sheilds and led them all to victory. Thus did he become the Emperor of Rome and subsequently moved the capital of the empire to Constantinople (formerly Byzas, now Istanbul) and most important for the history of the west -- proclaimed Christianity the official religion of the empire.
In context in GR there are various possible meanings: - The swastika, the broken cross at the mandala's center on the launch pad, the symbol of the Reich, shall win the war and proclaim a new empire -- the Third Reich which was to last a 1000 years -- which, come to think of it, was about as long as Constantinople was the center of the Roman, then Eastern Roman, then Byzantine (but always Christian) Empire (Constantinople falling to the Ottoman Turks in 1459). Common to both Nazi and Constantine rendering is the interplay of the Cross/Swastika over the face of the sun.
- Subsequently, the phrase became the motto of the Sobieski line -- Jan III Sobieski having defeated the Ottomans in 1683 at the Battle of Vienna just outside the city's gates. The phrase has also been used by Irish nobility, the Sacred Military Constantinian Order of Saint George, the Portuguese, the Knights Templars, Freemasons, and the Sigma Chi fraternity.
Which leads to the most amusing reading of the passage: whoever carved the words into the tree did so as a fraternity prank.

109.9-11 freak saffrons, streaming indigos
The isolated Dutchman going slowly mad under the southern sun, whose "very perceptions" are changed (and who writes numerous letters to his brother) seems to be a reference to Vincent Van Gogh; the kind of tacit anachronism that Pynchon likes to use in Mason & Dixon.
111.07-09 For as much as they are creatures of God and have the gift of rational discourse, acknowledging that only in his Word is eternal life to be found...
Weisenburger suggests that this is a prayer for new colonial subjects, but the context Frans van der Groov’s hopes for a Conversion of the Dodos suggests that it comes from a discourse on the possibility of salvation or conversion for Jews or others. Given Katje’s problematic relationship to the Holocaust, the passage becomes even more suggestively sinister. The sentence does suggest the views of James (or Jacob) Arminius, the Dutch theologian who broke with the Dutch Reformed Church over issues of predestination and election. Arminius argued that Christ’s salvation was available to all in contrast to the official church's staunch belief in predestination. Frans would extend that grace to dodos as well. Also see note at 555.29.
