stricte pliciformibus, pileo concoloribus ; stipite rigide, 
erecto v. subflexuoso (in sicco), atro subnitente glabro, levis- 
simo, ad basim non v. minute loniterque annulate incrassato ; 
ad corticem truncorum putrescentium in silva virginea, 
Caa-Guazu Brasiliæ. Species ab omnibus adhuc cognitis 
forma magnitudine mycelii inconsueti distinctissima ; speci- 
mina senescentia ac nonnihil obliterata, iterum inquirenda ; 
an novum genus ? ” According to Spegazzini’s description, 
the mycelium grows on dead trunks, not on living branches, 
and it is closely applied to the substratum, instead of being 
for the most part free as in if . equicrinis ; it also differs from 
M. equicrinis in being rather rigid. But Theissen states 
(loc. cit.) that the black tough mycelial cords climb either 
singly or in clusters up to the crown of a tree, or form thick 
tangles in the bushes. 
“ Marasmius bavianus Pat. Pileo convexo, dein piano, 
sulcato, centro umbonato, albido v. fulvo, 0*5-1 *5 mm. lato, 
tenui, pellicula cellulis clavatis, sursu m muricatis, subhyalinis 
obtecto ; lamellis pallidis, parum numerosis (7-8), adnatis ; 
stipite glabro, setaceo, rigido, lucente, brunneofulvo, supra 
albido, 2-3 cm. long., J mm. diam., sporis fusoideis uno apice 
obtusis, 10-12 X 3-4. Gregarius ad folia putria in silva Bavi, 
Tonkin Sinæ. Mycelium rhizomorphoideum lucens, ramo- 
sum. M. aciculiformi affinis.” This species would seem to 
be near M. equicrinis. But a specimen in Herb. British 
Museum (Balansa, Champignons du Tonkin, No. 106) consists 
of dead leaves bearing only barren stalks, about 0*1 mm. 
diam. ; there is no horse-hair ” mycelium. 
“ Marasmius Balansse Pat. Mycelio rhizomorphoideo, cæs- 
pitoso, gracili, 1 mm. cr. (but see below), rigido, glabro, 
nigrobrunneo, intus albo ; pileo campanulato convexo, margine 
deorsum involuto, 5 mm. lat., 3-4 mm. alt., brunneo, margine 
striato ; carne ex hyphis ramosis septatis, centro hyalinis, 
exterioribus brunneis intertexta ; lamellis distantibus, crassis, 
parum numerosis, albidis ; stipite centrali, 15-18 mm. long., 
gracili, rigido, brunneo -nigro, glabro, apice attenuate, 1 mm. 
cr. Ad ramos arborum, Tonkin, Sinæ. A. M. equicrini et 
trichorrhizo quoad mycehum abundans, differt statura majore.” 
This species appears to resemble M. obscuratus, from which it
