Simon M. Woods: Simon M. Woods is a British entrepreneur and former record producer.  Woods was the manager for the band UB40 after having seen them play at a pub, and turned down two offers on their behalf to release under 2 Tone Records, opting to release "Food For Thought" through another label, Graduate, before setting up Dep International that recorded and released UB40 internationally with enormous success.  Woods left the band in 1983 and started his own label, to which he signed Swans Way.  Woods ran his own marketing company before being hired on by the Birmingham School of Acting, and founded the European Drama Network, a film production company which makes movies based on classic plays.  Their first movie was "The Mandrake Root"; it was directed by Malachi Bogdanov and is based on a comedy written in 1512 by Niccolò Machiavelli.  In a co-production with Warwick Business School he wrote and directed "The Inferno Show presents Machiavelli The Prince of Comedy", a short comedy to celebrate the 500th anniversary of the writing of "The Prince".  Currently he is developing a movie, "From Ithaca With Love The Odyssey", a modern version of Homer's "The Odyssey" set in the modern day but made in Ancient Greek and Latin, loosely based on a play of the same name he produced in 2006 with director Malachi Bogdanov as part of the New Generation Arts Festival.

Wyatt wrote the original, longer textbook, "Manual of Conchology", upon which Poe based his shorter, condensed version.  Poe was the editor or compiler of the work.

Tuber oregonense: Tuber oregonense, commonly known as the Oregon white truffle, is a species of edible truffle in the genus "Tuber".  Described as new to science in 2010, the North American species is found on the western coast of the United States, from northern California to southern British Columbia west of the Cascade Range.  A mycorrhizal fungus, it grows in a symbiotic association with Douglas fir.  It overlaps in distribution with the closely related "T. gibbosum", but they have different growing seasons: "T. oregonense" typically appears from October through March, while "T. gibbosum" grows from January to June.  The fruit bodies of the fungus are roughly spherical to irregular in shape, and resemble small potatoes up to 5 cm in diameter.  Inside the truffle is the gleba, which is initially white before it becomes a marbled tan color.  The large, often thick-walled, and strongly ornamented spores are produced in large spherical asci.  The truffle is highly prized for its taste and aroma.  Some individuals have claimed success in cultivating the truffles in Christmas tree farms.
