79. MARASMIUS LACHNOPHYLLUS Atkinson's 
Mushr. 132, Agaricus lachnophyllus Berkeley. Lea's Cata¬ 
logue. 1849. 
Subcaespitose. Pileus a little fleshy, conic-hemispheric, of a 
rich tawny-brown, clothed with short, velvety pubescence, much 
wrinkled when dry. Stipe tough, hollow, brownish-purple below, 
shaded off into white above and clothed with scattered short 
pubescence, downy and rather bulbous at the base. Lamellae 
narrow, close, quite free, velvety with tawny pubescence; spores 
ovoid-oblong, obliquely apiculate, 6-8 x 3-4 mic. 
Growing on rotten wood amongst old leaves. Pileus 2 cm. 
in diameter, the stipe 5 cm. long and 2 mm. thick. The surface 
of the whole plant, pileus, stipe and lamellae is clothed with* 
brown setulae 70-90 mic. in length. 
80. MARASMIUS ALLIACEUS Fries Hym. EuR; 
Agaricus alliaceus Jacquin. Misc, Austr. 1778. 
Strong-smelling. Pileus submembranaceous, campanulate 
then expanded, subumbonate, even then sulcate, expallent. Stipe 
horny, tall, rigid, velvety-pruinate, black, the base rooting and 
naked. Lamellae free, dusky-white; spores elliptic-oblong, 10-12 
x 6-8 mic. 
Growing amongst old leaves on rotten wood. Pileus 2-4 cmi 
in diameter, the stipe 8-12 cm. long and about 3 mm. thick. There 
is no tinge of red in any part of the plant; the young pileus is 
often milk-white. It is particularly distinguished by its strong 
smell of garlic.

smaller and more delicate than the other.

Pileus membranaceous, convex then explanate, reddish, from* 
the even center to the spreading margin striatulate. Stipe tall,
