Very closely related to L. cristata, from which it only differs 

 by the shorter, more oval spores and the smaller cap with a 

 paler and but slightly cracked cuticle. As I have never seen it 

 since 1897, I cannot decide whether my plant is anything but a 

 mere form of L. cristata. 



19. L. micropholis B. et Br. 



Spores ovate, 4—5 x 2 3 / i — 374 u, Cystidia club-shaped, apex 

 7 — 8 [i broad. Scales on cap made up of grayish cells, inflated 

 in one end.

 subtropical house, April 1908. 



Evidently an introduced species. It has the smell of L. 

 cristata. 



C. GRANULOSÆ. 



a. ACUTESQUAMOSÆ. 



20. L. acutesquamosa (Weinm.). 



Spores cylindric-ellipsoid, obliquely pedicellate, 7- — 8 X 27a — 3 u 

 (1900); 7 1 /,— 8 x 2 3 / 4 — 3 ja; cystidia obovate-subrotund (1902, fig.).

 foliaceous woods, but rather sporadic and not every year. — 



Although this plant is one of the most characteristic of the 

 whole Agaric tribe, it seems to be very disputed by the authors 

 and often unsatisfactorily described. Thus Fries evidently con- 

 founds some of the characters of this species and of L. Friesii 

 (which latter he has not seen alive), attributing to the former the 

 pointed scales, to the latter the branched gills. The fact is that 

 in L. acutesquamosa the cap (even when in bud) is densely set 

 with erect, pointed, hard, somewhat deciduous warts, and the 

 gills repeatedly forked. By means of these characters it can be 

 easily distinguished from its allies. Quélet (1. cit.) describes it 

 very well under the name of L. aspera (under which name he 

 also includes L. Friesii). If he be right in this, the Friesian 

 description of L. Friesii may refer to large specimens of L. 

 acutesquamosa which have lost their warts. 



21. L. hispida (Lasch). (? L. fusco-squamea Peck) (Plate I, fig. e). 



Spores oval, 5 — 6 X 2 3 / 4 — 3u, with a small, oblique pedicel. 

 Basidia 4-spored. Cystidia 0.

 soil in a bog. under Fraxinus etc., a number of specimens, Oct. 

 1914; (first found by P. Larsen). 



This agaric looks very much like a small L. acutesquamosa 

 (cap 4 — 6 cm broad), but is easily distinguished by the undivided
