dc.description.abstract | Geastraceae is a monophyletic family included in the gomphoid-phalloid clade, it is
composed only by two genus: Geastrum and Myriostoma. These genus are closely
related in their morphology and phylogeny, both showing angiocarpic basidiomata,
apical stoma, basidiospores passively released by the bellows mechanism and
exoperidium dehiscent in rays, these genus are distinct by the number of stomas and
pedicels. Because of dehiscense of exoperidium they are popularly known as
“earthstars”. Usually they occur on decomposing leaf-litter and decaying wood. They
are, thus, saprophytic, with rare exceptions of ectomycorrhizal species. Geastrum is the
most diverse gasteroid genus in Brazil, with an estimated 51 records. However, there are
large gaps in the geographic distribution and systematics studies about the Geastrum in
this country, especially because of the characteristics found in the Brazilian territory
(megadiverse, hotspots and continental size), which makes it a priority area for species
inventory. Thus, this work was aimed at realizing inventory of species of Geastrum,
which occur in Caatinga and Northeastern Atlantic Rainforest. At least two field
expeditions were realized, during about four days on rainy season of 2013 and 2014 in
the areas: Reserva Biológica de Guaribas, located in Atlantic Rainforest domain,
Paraíba State and Reserva Ecológica Estadual Mata do Pau Ferro, located on “Brejos
Paraibanos”, Paraíba State. Furthermore, specimens deposited in the Herbarium of the
Universidade Federal do Rio Grande do Norte, which were collected in Parque Nacional
Vale do Catimbau, Caatinga of Pernambuco State, were analyzed. The specimens were
identified according to analysis of macro and micro morphology based on specific
literature. Approximately 400 basidiomata, distributed in 73 exsiccates were analyzed.
21 species were identified, 19 are in specie level, which two are proposed to new
species. (Geastrum magnosporum sp. nov. e G. pusillupilosum sp. nov.) and two in
genera level (sp. e aff.). We emphasize one new record for Brazil, 12 new records for
Paraíba State, four new records for semiarid region in Brazil and six new records to
Atlantic Rainforest relicts “Brejo de Altitude”. So, the results improved the knowledge
about Geastrum in Paraíba State by 200%, 24 % in Brazilian semiarid region and 55%
in Atlantic Rainforest relicts “Brejo de Altitude”, evincing that Northeastern Brazil has
high species richness. | |
