even if we exclude from Armillaria (as he does) A. mucida 

 (which has very thick -walled spores), I do not think this 

 character holds good. L. carcharias and others have just as 

 thin a spore-membrane as f. inst. Armillaria bulbigera or A. 

 mellea. 



Still, even if no single character can be regarded as abso- 

 lutely decisive, all the true Lepiotas are characterised by posses- 

 sing some or most of the above-mentioned characters. Thus the 

 Proceri have the distinct cap, the Granulosi the universal veil, 

 and so forth. 



Some of the Armillarias (sensu Fries) have very little in 

 common with the Lepiotas (f. inst. A. bulbigera, A. aurantia etc.) 

 while others (f. inst. A. mellea) run them very close. In fact 

 what is called »the genus Armillaria« is properly speaking no 

 genus at all but a heterogeneous mixture of agarics with white 

 spores and a peronate or annulate stem. And the most satis- 

 factory way of treating this spurious genus will therefore, I 

 think, be to split it up altogether, distributing its several species 

 among the adjoining genera. 



To a certain extend this has already been done by the 

 acute French mycologist Quélet. But I think it profitable to 

 carry this principle right through. 



I only speak here of the species known to me from personal 

 observation, viz. A. mellea, robusta (and its varieties), aurantia, 

 cingulata, ramentacea, bulbigera, mucida (and corticata). 



Of the above named species I think A. mellea is a fairly 

 genuine Lepiota, characterised by having a universal veil con- 

 crescent with the stem and cap. I accordingly include it in 

 the genus Lepiota. 



The case for A. robusta is not so clear. If the scales and 

 fibrils on the stem up to the ring are traces of a universal veil, 

 it probably should be placed in Lepiota. But by its general 

 habit and its spores it approaches Tricholoma, and I therefore 

 — although hesitatingly — refer it to this genus. 



To Tricholoma certainly must be transferred A. aurautia, 

 which — though the stem is peronately scaly — has no ring 

 (only some slight viscid drops in its place). It naturally fits 

 into the tribe Limaciua of Fries. 



A. cingulata is simply a Tricholoma gausapatum with a 

 distinct ring instead of an arachnoid veil. It consequently goes 

 into the tribe Genuina. — A. ramentacea (which I have only
