This common aummnal species, which is ordinarily known as 

 Hypholoma sublateritium or H. perplexum, was first described by 

 Schaeffer as Agaricus lateritius, but on his plate he unfortunately 

 used plants of H. fasciculare for the younger stages of his species, 

 and this has caused confusion. Hudson referred to this plate and 

 to Schaeffer's name when he described his A. fascicularis.
