These two species constituted Thwaites' 774. The figure 

 of ctchnous is also marked auctus var. achnous ; apparently 

 Berkeley and Broome named auctus first, but they published 

 the names in the order given above. The specimens named 

 achnoa had lost the scales which characterize aucta. 



On decaying twigs and leaves ; gregarious ; often connate 

 at the base. 



Pileus at first conical, then broadly conico-campanulate 

 with a reflexed margin, up to 2'5 cm. diameter and 1*5 cm. 

 high, membranaceous, white, becoming pale lavender, but 

 constantly white at the apex ; clothed at first with minute, 

 white, pointed, fibrillose scales which disappear leaving the 

 pileus shghtly atomate, smooth, appearing faintly radially 

 striate up to the white "apex when moist ; margin at first fim- 

 briate with white flocci, afterwards incised. The white apex is 

 accentuated in Thwaites' figures and appears to be a papillae- 

 form umbo, but this is not noticeable in fresh specimens. 

 Stalk up to 6 cm. long, 2 mm. diameter, equal, white, shining 

 and slightly mealy above, clothed with rather coarse white 

 flocci below, hollow, white internally. Gills adnexed, ascend- 

 ing, distant, rather broad (4 mm.), rounded below and visible 

 below the margin of the pileus, attenuated upwards, white, 

 then lavender, finally blackish- violet. Spores narrow-oval, 

 shghtly inequilateral, 13-14 X 6 ^, dark violet-brown when 

 magnified, violet-black in mass, with a minute hyaUne apiculus 

 and a hyaHne cap at the distal end.
