Tricholosporum Guzmán 1975
fungi genus in the tricholomataceae family
Tricholosporum is a genus of fungi in the family Tricholomataceae. It was circumscribed by Mexican mycologist Gastón Guzmán in 1975.
Psilocybe tampanensis Guzmán & S.H. Pollock 1978
fungi species in the hymenogastraceae family
Psilocybe tampanensis is a very rare psychedelic mushroom in the family Hymenogastraceae. Originally collected in the wild in a sandy meadow near Tampa, Florida, in 1977, the fungus would not be found in Florida again until 44 years later. The original Florida specimen was cloned, and descendants remain in wide circulation. The fruit bodies (mushrooms) produced by the fungus are yellowish-brown in color with convex to conic caps up to 2.4 cm (0.9 in) in diameter atop a thin stem up to 6 cm (2.4 in) long. Psilocybe tampanensis forms psychoactive truffle-like sclerotia that are known and sold
Psilocybe subcubensis Guzmán 1978
fungi species in the hymenogastraceae family
Psilocybe subcubensis is an entheogenic species of mushroom in the family Hymenogastraceae. The mushroom contains the chemical compounds psilocybin and psilocin. Psilocybe subcubensis was first described by Mexican mycologist Gaston Guzman. It is the pantropical sister species of Psilocybe cubensis. It is macroscopically identical to P. cubensis but has smaller spores.
Psilocybe aucklandiae (Psilocybe Aucklandii) Guzmán, C.C. King & Bandala 1991
fungi species in the hymenogastraceae family

The species is known from the Auckland Region of New Zealand, where it grows from clay soils in exotic pine plantations and native forests. It is phylogenetically similar to or almost the same as Psilocybe zapotecorum from Mexico and South America. As a blueing member of the genus Psilocybe it contains the psychoactive compounds psilocin and psilocybin.
Morchella rufobrunnea (Woodchip Morel) Guzmán & F. Tapia 1998
fungi species in the morchellaceae family
Morchella rufobrunnea, commonly known as the blushing morel, is a species of ascomycete fungus in the family Morchellaceae. A choice edible species, the fungus was described as new to science in 1998 by mycologists Gastón Guzmán and Fidel Tapia from collections made in Veracruz, Mexico. Its distribution was later revealed to be far more widespread after several DNA studies suggested that it is also present in the West Coast of the United States, Israel, Australia, Cyprus, Malta and Switzerland. M. rufobrunnea grows in disturbed soil or in woodchips used in landscaping as a saprotroph. Reports

Psilocybe tasmaniana Guzmán & Watling 1978
fungi species in the hymenogastraceae family

It was described by Gastón Guzmán and Roy Watling in 1978 as a small tawny orange mushroom that grows on dung, with a slight blueing reaction to damage, known only from Tasmania and southeastern Australia. It was likened to Psilocybe subaeruginosa although characteristics, appearance, and the association with dung were not typical for that species. As a blueing member of the genus Psilocybe it contains the psychoactive compounds psilocin and psilocybin. In 1992 an attempt was made to combine the

Pleurotus smithii Guzmán 1975
fungi species in the pleurotaceae family
Pleurotus smithii is a species of fungus in the family Pleurotaceae, described as new to science by mycologist Gastón Guzmán in 1975. Like other species of the Pleurotus cystidiosus clade, it has an anamorphic form, named Antromycopsis guzmanii. P. smithii can be distinguished from P. cystidiosus by lack of pleurocystidia or them being only present in young stages as cystidioid elements, short hyphal segments of the conidiophores in the anamorph, and long subcylindrical cheilocystidia in the teleomorph form.
Tyromyces subviridis Ryvarden & Guzmán 2001
fungi species in the incrustoporiaceae family
Tyromyces subviridis is a species of fungus in the family Polyporaceae. Found in Mexico, it was described as new to science in 2001 by mycologists Leif Ryvarden and Gastón Guzmán. The type collection was made in Cofre de Perote (Veracruz), where it was found fruiting on a log of unidentified origin. Characteristics of the fungus include its smooth, narrow, cap, the grey to pale green colour of the pore surface and tooth-like pore mouths, and tubes that contrast with the distinctly paler context.
Tyromyces mexicanus Ryvarden & Guzmán 2001
fungi species in the incrustoporiaceae family
Tyromyces mexicanus is a species of fungus in the family Polyporaceae. Found in Mexico, it was described as new to science in 2001 by mycologists Leif Ryvarden and Gastón Guzmán. The type collection was made in Cofre de Perote (Veracruz), where it was found fruiting on a dead coniferous log in a spruce and pine forest. The fungus is characterized by its dark, grooved cap, white pore surface, and a thin context that is coloured white to grey.

Psilocybe hispanica Guzmán 2000
fungi species in the hymenogastraceae family
Psilocybe hispanica is a species of fungus in the family Hymenogastraceae. It produces small brown mushrooms with conical to convex caps up to 10 mm (0.4 in) in diameter and stems 16 to 25 mm (0.6 to 1.0 in) long by 0.5 to 1 mm (0.02 to 0.04 in) thick. Reported as new to science in 2000, it is only known from the Pyrenees mountain range in northern Spain and southwestern France, where it grows on horse dung in grass fields at elevations of 1,700 to 2,300 m (5,600 to 7,500 ft). The mushroom contains the psychoactive compound psilocybin. The possible depiction of this species in the
Psilocybe acutipilea (Speg.) Guzmán 1978
fungi species in the hymenogastraceae family
Psilocybe acutipilea is a species of mushroom-forming fungus in the family Hymenogastraceae. It was discovered in October 1881 in Apiahy, Sao Paulo State, Brazil by Carlos Spegazzini, and described by him as a new species of Deconica in 1889. Gastón Guzmán transferred it to Psilocybe in 1978, but Ramirez-Cruz considered it a possible synonym of Psilocybe mexicana, but the type specimen was too moldy for them to be certain.
