Schröt (1889) Inocybe praetervisa is a small, yellow and brown mushroom in the family Inocybaceae, distinguished from other members of the genus by its unusual spores and bulb.

I. praetervisa grows on the ground in woodland, favouring beech trees, and is found in Europe, North America and Asia.

Inocybe praetervisa was first described by Lucien Quélet in the first volume of Giacomo Bresadola's 1883 publication Fungi tridentini.

However, when phylogenetic analysis later concluded that nodulose-spored Inocybe species do not form a monophyletic group, the name Astrosporina was deemed inappropriate at a generic level.

It is white, maturing to a pale straw-yellow, and the whole stem is farinaceous, meaning it is covered in particles resembling meal.

[8][9][14] Mushrooms grow solitarily or in "trooping groups"[10] in late summer and throughout autumn, though it is not commonly encountered species.

Consumption of muscarine could lead to a number of physiological effects, including: excess salivation, lacrimation, uncontrollable urination and defecation, gastrointestinal problems and emesis (vomiting); this array of symptoms is also known by the acronym SLUDGE.

[16] Other potential effects include a drop in blood pressure, sweating and death due to respiratory failure.
