Abstract: Four new Asterolibertia species and a new variety of Cirsosia splendida, all found on native
Cerrado plants, belonging to three host families are described, illustrated and named as: A. bahiensis sp.
nov. on Erythroxylum sp. (Erythroxylaceae); A. barrinhensis sp. nov. on Diospyros burchellii (Ebenaceae);
A. campograndensis sp. nov. on Hirtella glandulosa (Chrysobalanaceae); A. parinaricola sp. nov. on Parinari
obtusifolia (Chrysobalanaceae); and Cirsosia splendida var. laevigata var. nov., showing both sexual and
asexual morphs, on H. glandulosa and H. gracilipes (Chrysobalanaceae). Finally, A. licaniae is reported on a
new host, H. gracilipes. Keys to all the known species of Asterolibertia and Cirsosia are included.

INTRODUCTION
Molecular data are generally unavailable for members of
Asterinaceae and the taxonomy of most genera in this family
to date relies chiey on morphological data. That is the case
of Asterolibertia and Cirsosia. Overcoming this limitation will
depend on recollecting the taxa described in the past and
where appropriate epitypifying these after extracting and
sequencing genomic DNA. There have been a few cases
where this was performed successfully from old herbarium
specimens (Telle & Thines 2008, O’Gorman et al. 2010,
Hawksworth 2013, Guatimosim et al. 2015, Thomas et al.
2015).
The genera of Asterinaceae are presently segregated using
well-dened morphological characters, such as the presence
or absence of appressoria on the external mycelium, setae
on ascomata and/or on the external mycelium, appressorium
type (intercalary or lateral), and ascospore septation (Bezerra
2004, Hosagoudar 2012). Within the family, only three genera
have intercalary appressoria: Asterolibertia, Cirsosia, and
Bheemamyces (Arnaud 1918, Bezerra 2004, Hosagoudar
2010, 2012). However, in Bheemamyces the appressoria are
both lateral and intercalary (Hosagoudar et al. 2010).
For almost a century, Asterolibertia was considered a
well-supported genus, due to the presence of intercalary
appressoria as originally established by Arnaud (1918), and
this has been always regarded as a strong morphological
character. However, Hongsanan et al. (2014), without any
molecular basis and morphological justication, recombined
species of Asterolibertia into Asterina, a genus with species
showing only lateral appressoria. Such recombinations must
be regarded as questionable, particularly in the absence of
molecular data.
Currently, Asterolibertia includes 35 species (Tables
1–2) found only in the tropics and mainly on the host
families Chrysobalanaceae, Malpighiaceae, and Rubiaceae
(Hosagoudar 2010, Farr & Rossman 2015). The genus
Cirsosia accommodates 15 species and one variety, all
from the tropics (Tables 3–4), found mainly on Arecaceae,
Chrysobalanaceae, Dipterocarpaceae, and Malpighiaceae
(Hosagoudar 2010, Farr & Rossman 2015).
Asterolibertia couepiae, the type species of the genus,
was collected in the Brazilian Cerrado by Ule in 1892, while
C. manaosensis, the type species of Cirsosia, also from Brazil,
was collected also by Ule in the Amazonian forest (Arnaud
1918). Asterolibertia species are characterized by having
circular thyriothecial ascomata opening by a central star-
shape ssure, adhering to the host by supercial hyphae with
intercalary appressoria, and showing 2-celled ascospores.
Cirsosia species differ from Asterolibertia in the lirelliform or
V–Y-shaped ascomata, opening by a longitudinal ssure.
However, as in Asterolibertia, Cirsosia species have supercial
hyphae with intercalary appressoria and 2-celled ascospores
(Bezerra 2004, Hosagoudar 2010, 2012). The specimens
studied here were collected from different areas of the Brazilian
Cerrado (including a fragment of Cerrado vegetation inserted
in an area of the Brazilian Atlantic Forest in the State of Bahia)
and yielded what is here recognised as novel taxa and host-
associations for Asterolibertia and Cirsosia.
This paper describes four new Asterolibertia species,
a new variety of C. splendida, and illustrates A. licaniae in
association with a new host.

volume 7 · no. 1
MATERIAL AND METHODS
Leaves bearing black colonies were collected and dried
in a plant press before being processed and deposited in
the Fungarium known as the UB Mycological Collection, a
part of Herbarium UB (Universidade de Brasília). Colonies
were initially examined using a Zeiss Discovery v.8
stereomicroscope. Entire colonies were removed from the
leaves by applying small drops of nail polish. After these
had solidied and fungal structures became embedded
preventing the collapse of the colonies, these were
peeled from the leaf surfaces. These colonies and small
samples taken directly from the leaves were mounted
on slides containing lacto-glycerol for light microscopic
observations. Imaging and measurements were done
using a Leica DM 2500 light microscope adapted with a
DFC 490 Leica digital camera, operated by a Leica Qwin
Plus digital image-processing software. For scanning
electron microscopy (SEM), air-dried material was xed
to disks using carbon double-sided tape, and then treated
with gold using a 25-mA current, at 1.10–2 mbar for 2 min
and 30 s. Photographs were obtained using a JEOL Model
JSM-700 1 F SEM.
RESULTS
A total of 35 species of Asterolibertia have previously been
described on 19 different host families (Hosagoudar 2010,
Farr & Rossman 2015). These have been described on the
families: Chrysobalanaceae (9 species, including two new
species described here), Rubiaceae (4); Anacardiaceae,
Annonaceae, Dipterocarpaceae, Fabaceae, and
Malpighiaceae (2 on each); and Achariaceae, Arecaceae,
Bignoniaceae, Bromeliaceae, Burseraceae, Ebenaceae
(described here), Erythroxylaceae (described here),
Euphorbiaceae, Lauraceae, Melastomataceae,
Myrtaceae, Poaceae, Polygalaceae, and Styracaceae
(1 on each; Table 2). Asterolibertia bredemeyerae was
reported from two different families (Polygalaceae and
Fabaceae), as well as A. schroeteri (Annonaceae and
Chrysobalanaceae) and A. peruviana (Bignoniaceae and
Chrysobalanaceae). However, A. peruviana apparently
belongs to Microthyriaceae due to the well-dened circular
ostiole present on the ascomata (Hansford 1955, Wu et al.
2011). As Asterolibertia species are usually host specic, a
reevaluation of the three species that occur in two different
host families is recommended.
A total of 15 species and one variety of Cirsosia have
been described on six different host families (Hosagoudar
2010, Hofmann & Piepenbring 2014, Farr & Rossman
2015): Dipterocarpaceae (5 species); Arecaceae (4);
Chrysobalanaceae (3, including the new variety described
here); Malpighiaceae (2); and Burseraceae and Lauraceae
(1 on each; Table 4). There is no record of the same
Cirsosia species being found on two different host families
(Hosagoudar 2010, Farr & Rossman 2015).
TAXONOMY
The data in Tables 1–4 that include the characteristics of the
new taxa herein proposed were used to formulate the keys
provided for the identication of Asterolibertia and Cirsosia
species, thus simplifying the text.
Asterolibertia bahiensis Firmino, Inácio & Dianese,
sp. nov.
MycoBank MB813315
(Fig. 1)
Etymology: Refers to the state of Bahia where the fungus
was collected.
Diagnosis: Asterolibertia bahiensis is quite close to A.
nodulifera but differs in having smaller paraphysate ascomata
and larger appressoria.
Type: Brazil: Bahia: Una, Bolandeira Farm, on an enclosure
of Cerrado vegetation in the Brazilian Atlantic Forest, close
to the entrance to Comandatuba Island, 15° 21’ 12.7” S 39°

Description: Colonies amphigenous, circular to irregular,
single to conuent, black, 1–12 mm diam. Hyphae straight
to exuous, branching irregularly, pale brown, septate,
hyphal cells cylindrical, 4–5 μm diam, smooth. Appressoria
numerous, entire, sessile, intercalary, elongated with a
lateral protuberance, unicellular, 14–17.5 × 9–10 μm, brown,
penetration peg central on the appressorial cell. Ascomata
supercial, thyriothecia, scutiform, on top of mycelial mat,
circular, single to conuent, fringed at margins, randomly
distributed in the colony, 175–235 μm diam, opening by a
central star-shaped ssure, dark brown; wall of textura
radiata, cells cylindrical. Pseudoparaphyses cylindrical,

in structure, ssitunicate, disposed as an upright palisade
layer, globose to ovoid, 8-spored, hyaline, 35–52.5 × 30–
42.5 μm. Ascospores cylindrical, ends rounded, straight or
slightly arched, 1-septate, constricted at the septum at the
supramedian septum, hyaline, becoming brown at maturity,
verruculose, 32.5–37.5 × 10–14 μm. Asexual morph not seen.
Other specimens examined: On leaves of Erythroxylum sp.
(Erythroxylaceae). Brazil: Minas Gerais: Buritis, Pedra Grande Farm,
8 May 1993, J. C. Dianese 863 (UB-Mycol Col. 3934). Bahia: Una,
on an enclosure of Cerrado vegetation in the Brazilian Atlantic Forest
at Fazenda Bolandeira, near entrance to Comandatuba Island, J.C.
Dianese (UB-Mycol Col. 9871).
Notes: The type material was collected in a rare small
enclosure of Cerrado vegetation in the Brazilian Atlantic
Forest. However another specimen (UB – Mycol Col. 3934)
was found in a typical Cerrado natural landscape in Buritis,
Minas Gerais. In addition, this is the rst Asterolibertia
species found on a member of Erythroxylaceae (Hosagoudar
2010, Farr & Rossman 2015).

Notes: This new Asterolibertia species is the rst reported on
a member of Ebenaceae (Hosagoudar 2010, Farr & Rossman
2015). It shows characteristics in common with several
species (Tables 1–2), including the one described below,
but clear differences persist as shown in the discussion that
follows the description of A. campograndensis.
Asterolibertia campograndensis Firmino & Dianese,
sp. nov.
MycoBank MB813317
(Fig. 3)
Etymology: Epithet refers to the city where the fungus was
collected, Campo Grande.
Diagnosis: Asterolibertia campograndensis differs from
A. parinarii in having larger hyphae, appressoria and
ascospores, and globose to ovoid asci.
Type: Brazil: Mato Grosso do Sul: Campo Grande, left lane
of BR-163 Highway, 200 m from the roundabout turn to São
Paulo, behind Cerealista Juliana, 20° 35’ 8.58” S 54° 34’ 49.51”
W, on leaves of Hirtella glandulosa (Chrysobalanaceae), 22
Aug. 1996, M. Sanchez (UB-Mycol Col. 12712a – holotype).

30 × 9.5–10.5 μm. Asexual morph not seen.
Notes: Seven species of Asterolibertia have been
reported previously in association with living leaves of
chrysobalanaceous hosts. Four of these were recorded from
Brazil: A. couepiae on Couepia grandiora, A. licaniae and
A. licaniicola on Licania sp., and A. peruviana on Licania
macrophylla. Additionally, A. nodulifera was recorded on
Angelesia splendens from the Philippines, A. parinarii on
Parinari subcordata from the Democratic Republic of the
Congo, and A. schroeteri on Chrysobalanus icaco from India
(Arnaud 1918, Hansford 1947, 1949, 1955, Müller & von Arx
1962, Hosagoudar 2010, Hofmann & Piepenbring 2014, Farr
& Rossman 2015).
Asterolibertia campograndensis differs from the species
previously reported on Chrysobalanaceae (Table 1) (Arnaud
1918, Hansford 1947, 1949, 1955, Müller & von Arx 1962,
Hosagoudar 2010, Hofmann & Piepenbring 2014, Farr &
Rossman 2015). It is closest to A. parinarii, which has smaller
appressoria and ascospores, narrower hyphae, and ellipsoid
to subglobose asci. Asterolibertia couepiae is distinct from
the new species in having black hyphae, larger thyriothecial
ascomata, lacking pseudoparaphyses, 4–6-spored asci, and
ovoid ascospores. Asterolibertia nodulifera has amphigenous
colonies, no pseudoparaphyses, larger ascomata and larger,
echinulate ascospores. Asterolibertia licaniae differs from A.
campograndensis in the dark brown hyphae, barrel-shaped
and larger appressoria, ascomatal dehiscence by an irregular
ssure, a lack of fringes at the margins of the ascomata, the
absence of pseudoparaphyses, and nally larger, ellipsoidal,
dark brown ascospores with a central septum. Asterolibertia

licaniicola differs from A. campograndensis in the wider
hyphae, barrel-shaped appressoria, larger ascomata,
absence of pseudoparaphyses, and dark brown ascospores
with a central septum. Asterolibertia peruviana has
narrower appressoria, larger ascomata that are not fringed
at the margins, and smaller appressoria and ascospores.
Asterolibertia schroeteri differs in the larger ascomata with
an irregular ssure, the absence of pseudoparaphyses,
and larger asci and ascospores (Tables 1–2) (Arnaud 1918,
Hansford 1947, 1949, 1955, Müller & von Arx 1962, Hofmann
& Piepenbring 2014).
Asterolibertia campograndensis is morphologically
rather similar to A. barrinhensis. However, these species
differ in important morphological details such as ascospore
ornamentation, the shape of the ascomatal fringes (loosely set
in A. barrinhensis), and hyphal branching patterns (opposite
in A. barrinhesis, and irregular in A. campograndensis).
Asterolibertia campograndensis is the fth species
of Asterolibertia reported on hosts belonging to
Chrysobalanaceae in Brazil, and the rst on Hirtella.
Asterolibertia parinaricola Firmino, Inácio & Dianese,
sp. nov.
MycoBank MB813319
(Fig. 4)
Etymology: Refers to the host genus, Parinari.
Diagnosis: Asterolibertia parinaricola differs from A.
licaniicola in having conspicuous lateral protuberance of
the appressoria, presence of pseudoparaphyses, and much
larger, verruculose ascospores constricted at a supramedian
septum.
Type: Brazil: Distrito Federal: Brasília, PAD-DF, on leaves
of Parinari obtusifolia (Chrysobalanaceae), 10 Nov. 1992, C.
Furlanetto (UB-Mycol Col. 2567 – holotype).
Description: Colonies epiphyllous, circular or irregular, single
or conuent, black, 3–10 mm diam. Hyphae straight, with
opposite branches, brown, septate, hyphal cells cylindrical,
4.5–5.5 μm diam, smooth. Appressoria numerous,
entire, intercalary, elliptical or with a lateral protuberance,
unicellular, 10–15 × 7–9 μm, brown, penetration peg central
on the appressorial cells. Ascomata supercial, thyriothecia,
scutiform, on top of a mycelial mat, circular, single to
conuent, fringed at the margins, randomly distributed in the
colony, 150–207 μm diam, opening by a central star-shaped
ssure, dark brown; wall textura radiata, with isodiametrical
cells. Pseudoparaphyses cylindrical, septate, branched,
hyaline, 1–1.5 μm wide. Asci bitunicate in structure,
ssitunicate, disposed as an upright palisade layer, globose
to ovoid, 8-spored, hyaline, 37.5–47.5 × 29–32.5 μm.
Ascospores oblong to oblong-clavate, ends rounded, straight
to slightly arched, 1-septate, constricted at the supramedian
septum, hyaline, becoming pale brown to brown at maturity,
verruculose, 34–40 × 10–14 μm. Asexual morph not seen.
Other specimens examined: On leaves of Parinari obtusifolia
(Chrysobalanaceae). Brazil: Maranhão: Nogueiras, 60 km North of
Balsas, 6° 57’ 52.47” S 46° 10’ 13.19” W, 11 Apr. 1995, M. A. de
Freitas (UB-Mycol Col. 8020). Distrito Federal: Brasília, PAD-DF, 04
Nov. 1993, C. Furlanetto (UB-Mycol Col. 2568 and 2569).
Notes: Seven species of Asterolibertia have been
reported previously in association with living leaves of
chrysobalanaceous hosts. Asterolibertia couepiae on
Couepia grandiora from Brazil, A. nodulifera on Angelesia
splendens from the Philippines, A. licaniae and A. licaniicola
on Licania sp. from Brazil, A. parinarii on Parinari subcordata
from the Democratic Republic of the Congo, A. peruviana
on Licania macrophylla from Brazil, and A. schroeteri on
Chrysobalanus icaco from India (Arnaud 1918, Hansford
1947, 1949, 1955, Müller & von Arx 1962, Hosagoudar 2010,
Hofmann & Piepenbring 2014, Farr & Rossman 2015).
Asterolibertia parinaricola differs from the species
previously reported on Chrysobalanaceae (Table 1) (Arnaud
1918, Hansford 1947, 1949, 1955, Müller & von Arx 1962,
Hosagoudar 2010, Hofmann & Piepenbring 2014, Farr
& Rossman 2015), and is most similar to A. licaniicola.
However, the latter has barrel-shaped appressoria, no
pseudoparaphyses, and much smaller, smooth ascospores
constricted at the central septum. Asterolibertia couepiae
differs from the new species in the wider hyphae, lack of
pseudoparaphyses, smaller asci and ascospores, and
smooth ascospores. Asterolibertia nodulifera differs in
the amphigenous colonies, smaller thyrothecia, lack
of pseudoparaphyses, and echinulate ascospores.
Additionally, A. licaniae differs from the new species in
the larger thyriothecia and wider hyphae, barrel-shaped
appressoria, the lack of pseudoparaphyses, and smaller,
ellipsoidal, smooth ascospores that are constricted at the
central septum. Asterolibertia parinarii has narrower hyphae,
unbranched pseudoparaphyses, smaller appressoria, asci
and ascospores, and also smooth ascospores. Asterolibertia
parinaricola and A. parinarii are described on the same host
genus, but on different Parinari species. Besides, there is
no record of the host species of A. parinarii in Brazil, further
supporting that they are really distinct species (Sothers et
al. 2015). Asterolibertia peruviana has narrower appressoria
without a lateral protuberance to one side of the hypha,
and smaller, smooth ascospores. Finally, A. schroeteri
differs from A. parinaricola in the larger thyriothecia, asci
and hyphae, the lack of pseudoparaphyses, and smooth
ascospores (Tables 1–2) (Arnaud 1918, Hansford 1947,
1949, 1955, Müller & von Arx 1962, Hofmann & Piepenbring
2014). Asterolibertia campograndensis, newly described
above, differs in the unbranched pseudoparaphyses and
smaller, smooth ascospores.
Asterolibertia parinaricola is distinct from all seven
species known on Chrysobalanaceae, and represents the
sixth species of Asterolibertia reported on this host family in
Brazil. This is the second species of Asterolibertia described
on Parinari, and the rst species found on P. obtusifolia.

Asterolibertia and Cirsosia from the Cerrado

volume 7 · no. 1
Notes: Two species of Cirsosia have been reported previously
in association with living leaves of chrysobalanaceous hosts:
C. moquileae on Licania tomentosa from Brazil, and C.
splendida on Hirtella americana, Chrysobalanus icaco, and H.
triandra from Brazil, Panama, and Puerto Rico, respectively
(Batista & Maia 1960b, Hosagoudar 2010, Hofmann &
Piepenbring 2014, Farr & Rossman 2015).
Cirsosia splendida var. laevigata, the rst Asterinaceae
reported on H. glandulosa and H. gracilipes, is almost identical
to C. splendida, except for the smaller ascomata, presence of
pseudoparaphyses, and smooth ascospores (Batista & Maia
1960b, Hofmann & Piepenbring 2014). Such differences are
here considered enough to recognize the specimen studied
as a new variety of C. splendida. Furthermore, both occur on
the same host genus in Brazil, but on different species.
Finally, Cirsosia moquileae differs from the new variety by
dehiscence through a central star-shaped ssure (instead of
the longitudinal ssure normally shown in Cirsosia species),
and narrower ascospores (Batista & Maia 1960b). Indeed,
such a form of dehiscence and the shape of the ascomata
in C. moquileae indicate that that species could be better
accommodated in Asterolibertia (Batista & Maia 1960b).
