INTRODUCTION
The western African oceanic island of Sa˜o Tome´in
the Gulf of Guinea minimally 255 km west of
mainland Africa is volcanic in origin, approximately
13 000 000 y old (Lee et al 1994) and was never part of
or connected by a land bridge to the African
mainland. For some groups of organisms their
biodiversity on Sa˜o Tome´ is relatively well known
and show significant endemism. For example 601
species of plants have been recorded, of which 81
species (14%) are endemic (Figueiredo 1994). Ten
species of mammals (three endemic, 30%), 50 species
of birds (15 endemic, 30%), 14 species of reptiles
(one endemic, 7%) and five species of amphibians
(five endemic, 100%) have been documented from
the island (cited by Measey et al 2007). Knowledge of
the diversity of fungi from the Gulf of Guinea islands
is far more limited because until recently no biotic
surveys of the mycota from the region had been
conducted. In Apr 2006 (2 wk) and Apr 2008 (3 wk)
we conducted extensive fieldwork on Sa˜o Tome´ (and
on Prı´ncipe in 2008) documenting the diversity of
macrofungi (fleshy basidiomycetes and ascomycetes).
In 5 wk of collecting we obtained specimens, com-
prehensive descriptions and photographs represent-
ing approximately 225 species belonging to 91
genera. Analyses of this material will be published
elsewhere. Among the interesting species encoun-
tered, was a small, lignicolous species of
Phallus
(Basidiomycota, Agaricomycetes, Phallales) described
as new herein.
The gasteromycetes and in particular the phalloid
fungi of western Africa are well known, primarily
through the works of Dring (1964) and Dring and
Rose (1976). In these publications only four species
of
Phallus
were reported, namely
P. aurantiacus
Mont. (now considered a synonym of
P. rubicundus
),
P. indusiatus
Vent.: Pers.,
P. roseus
Delile (as
Itajahya
rosea
(Delile) E. Fisch.) and
P. rubicundus
(Bosc) Fr.
None of the species reported from western Africa
bear close resemblance to the new species nor do any
of the other 28 currently recognized species of
Phallus
(Kreisel 1996, Calonge 2005). Based on a
unique combination of small size, reticulate white
pileus, reticulate, white, decurved pseudostipe, brown
volva, lignicolous habit and relatively broad basidio-
spores, the Sa˜o Tome´ material is described as a new
species.
MATERIALS AND METHODS
All specimens were dried on a NescoHfood dehydrator,
packed in airtight plastic bags and hand carried back to the
US. Macromorphological data were derived from fresh
specimens, whereas micromorphological data were derived
from dried specimens rehydrated in ethanol followed by
distilled water, 3%KOH or Melzer’s reagent. Morphological
terms for phalloid fungi follow those of Calonge (1998).
Color terms and notations are those of Kornerup and
Wanscher (1978). Spore statistics include
x
m
, the arithmetic
mean of the spore length by spore width (6standard
deviation) for n spores measured; Q, the quotient of spore
length and spore width in any one spore, indicated as a
range of variation in n spores measured; Q
m
, the mean of Q-
values (6standard deviation). Herbarium acronyms are
from Holmgren et al (1990).

Commentary.
Distinctive features of
Phallus drewesii
include a brown to grayish brown, areolate-felted volva,
reticulate-lacunose, white pseudostipe, a reticulate
pileus that is white under the olivaceous brown gleba,
and lack of an indusium. Basidiomes typically develop
on the sides of fallen logs and the rigid pseudostipe is
decurved at maturity. No other known small
Phallus
species has been described with a combination of
reticulate pileus (receptacle) and reticulate-lacunose
pseudostipe. In the recently published key to the known
worldwide members of genus
Phallus
(Calonge 2005;
circumscribed broadly to include
Dictyophora
Desv.,
Hymenophallus
Nees,
Ithyphallus
[Fr.] E. Fisch.,

Speg.,

[Pat.] Lloyd, and
Endophallus

R.H. Petersen), species potentially allied with
P. drewesii
include the following.
Phallus minusculus
Kreisel &
Calonge (5
P. tenuis sensu
Calonge et al 1997),
described recently from Tanzania, differs in forming
smaller basidiomes with a reticulate pileus 8–10 32–
5 mm, a spongy (not reticulate) pseudostipe 25–33 31–
3 mm, and smaller basidiospores 2–3 31.0–1.5 mm
(Calonge and Kreisel 2002).
Phallus pygmaeus
Baseia,
described recently from Brasil, differs in forming smaller
basidiomes with smooth (not reticulate) pileus approx-
imately 3 mm tall, a tiny, reticulate pseudostipe 5–10 3
1–2 mm, and narrower basidiospores 1.0–1.5 mmdiam
(Baseia et al 2003).
Phallus tenuis
(E. Fisch.) O. Kuntze,
known from Sri Lanka, Java and China, differs in
forming larger basidiomes with a reticulate, yellow pileus
20–25 mm tall, and a yellow, spongy (not reticulate)
pseudostipe 70–100 mm tall (Liu 1984, Calonge 2005).
Last, the long forgotten epithet
P. xylogenus
Mont.,
based on material from Guyana, represents a species
with small basidiomes (pileus 3 mm broad, pseudostipe
ca. 10 32 mm) but differs in forming a perforated,
longitudinally subsulcate pseudostipe (‘‘
primitus cri-
broso
,
tandem longitrorsum subsulcato
’’) and smooth,
nonperforate pileus (Montagne 1854).
