Agarics, between Lcpiota and ArmiUaria. This sub-genus 

 is elevated to a genus and placed next to Coprinus by 

 Dr. M. C. Cooke, in the new edition of his Handbook of 

 British Fungi (now in course of publication in GreriUea), 

 and by the Rev. John Stevenson in his British Fungi — 

 Hyinenomycetes. Both authors seem to have overlooked 

 the later views of Fries, the founder of the section Hiatula, 

 as published in the Transactions of the Woolhope Club, 

 1870 (p. 179). Fries there says : " The space in the series 

 Leucospori, left vacant between 2 and 3 " (Lepiota and 

 Arniillaria — analogous with Phiteus and Pilosace) , "is very 

 well filled by the sub-genus Hiatula, described in my work 

 Nov. Si/m. Myc. Of this genus there are numerous tropical 

 species, and two are found growing in our hot-houses on the 

 stems of orchids. They have been found growing in a similar 

 situation at Amsterdam." Fries was obviously right in 

 his later determination, as Hiatula agrees exactly in struc- 

 ture and habit with Pluteus, Phiteolus, and Pilosace. 



Amongst the rosy-spored Agarics, the sub-genus Eccilia, 

 unknown as British when the first edition of the Outlines 

 was published, is now represented by nine species. The 

 sub-genus Claudopus contains three species, removed from 

 Crepidotus, the spores being rosy, and not truly brown. 



Amongst the brown-spored Agarics, five sub-genera have 

 been added since the publication of the Outlines. The 

 first is Acetabularia, which corresponds with Amanita and 

 Volvaria ; the next is Togaria, which corresponds with 

 Lepiota and the non-British Annularia. Togaria was 

 suggested by Fries, whose words, published in the 

 Trans. Woolhope Club., 1870 (p. 179), are " Agaricus aureus 

 occupies in the series Dermini the space between Lepiota 

 and Psalliota, which would readily maintain the type of
