While this specimen as mentioned above is quite typical I 
have, yet with some doubt, referred another specimen (my collec- 
tions Nr. 1106) to this species (Fig. 3). The specimen in question 
is large, the stipe being about 20 cm. long and the flabellum 8 cm. 
high and 11 cm. broad; the margin of the flabellum is irregularly 
lobed. The filaments of the interior of the flabellum are cylindric 
(Fig. 3 a, b), about 50 y thick, those of the surface thin, about 20 a 
and rather torulose or sometimes even moliniform (Fig. 3c). Howe 
gives the diameter of the filaments as 28—70 y and writes about 
the filaments: “rarely here and there subtorulose”. This plant 
seems to me, in a striking way, similar to the figure of Kützing 
(ies pl 28) 
Avrainvillea asarifolia nov. sp. 
Flabelliformis, colore sordide olivaceo-viridi; rhizoma teres, sti- 
pes cylindricus in superiore parte complanatus, leniter in flabellum 
terminale transiens; flabellum oblonge reniforme, basi cordata 
aut cuneata, margine integro aut lobato, tenue et membranaceum, 
satis distincte zonatum. Filamenta interioris flabelli sæpius paullo 
moniliformia aut torulosa aut cylindrica, supra dichotomiam con- 
stricta. Latitudo filamentorum 20—30 „u, sæpius 24—27 y. 
Filamenta superficiei tenuiora, torulosiora magisque ramosa et inter 
se plexa, latitudo 8—10—13 y, apice filamentorum interdum in 
pilum elongato [Tab. nostr. III]. 
Dark-olive-green or sometimes greyish when dried; most pro- 
bably of a similar colour when living; rhizome terete; stipe cylin- 
dric, in the lower part more flattened, higher up 6—23 cm. long, 
about 7 mm. in diameter; flabellum oblong-reniform with cordate 
base or especially in older specimens with more or less cunate base 
until about 10 cm. high and 14 cm. broad, entire or lobed, thin 
and membranaceous, of a rather firm consistency, being for the 
most part rather clearly zonate; the surface subglabrous, under a 
lens fine granulated. Filaments in the interior of the flabellum 
cylindric or often slightly moniliform or torulose with a rather
