“…As in phalloid fungi in general, few morphological characters are available to delimit species in Phallus . In addition, most of the widely used diagnostic characters – such as colour and sizes – show high plasticity, another factor that may lead to misidentifications and mask the real diversity within the genus (Kreisel 1996, Calonge 2005). As a consequence of these taxonomic uncertainties, a great number of synonyms are reported for several species of this clade.…”

“…As a consequence of these taxonomic uncertainties, a great number of synonyms are reported for several species of this clade. Phallus indusiatus is an emblematic example, where at least nineteen synonyms and several distinct forms have been described (Lloyd 1909, Liu 1984, Guzmán et al 1990, Kreisel 1996, Calonge 2005, Das et al 2007, Cheype 2010).…”

“…Desv. Kreisel (1996) considered that the importance of an indusium for the taxonomy of the genus was overestimated, hence he downgraded Dictyophora to a section of Phallus . More recently, with the introduction of molecular data to the systematics and taxonomy of fungi, studies have shown that the indusium is a recurrent character, which independently emerged several times during the evolution of the group (Hosaka et al 2006, Cabral et al 2012, Marincowitz et al 2015, Trierveiler-Pereira et al 2017).…”

Studies have demonstrated that many cosmopolitan species actually consist of divergent clades that present high levels of morphological stasis throughout their evolutionary histories. Phallus indusiatus s.l. has been described as a circum-tropical species. However, this distribution may actually reflect the lack of taxonomic resolution due to the small number of diagnostic morphological characters, which leads to the identification of new records as populations of P. indusiatus. Here, we examine the diversity of P. indusiatus-like species in Brazilian Amazonia. We show a clear congruence between detailed morphological data and ITS, nuc-LSU and atp6 based phylogenetic analyses and three new species are described within the Brazilian indusiate clade. These results highlight the importance of more detailed investigation, with the inclusion of molecular information, in Neotropical fungi.

Phylogenetic placement of Itajahya: An unusual Jacaranda fungal associate

et al. 2015

Itajahya is a member of Phallales (Agaricomycetes), which, based on the presence of a calyptra and DNA sequence data for I. rosea, has recently been raised to generic status from a subgenus of Phallus. The type species of the genus, I. galericulata, is commonly known as the Jacaranda stinkhorn in Pretoria, South Africa, which is the only area where the fungus is known outside the Americas. The common name is derived from its association with the South American originating Jacaranda mimosifolia trees in the city. The aim of this study was to consider the unusual occurrence of the fungus in South Africa, to place it on the available Phallales phylogeny and to test whether it merits generic status. Fresh basidiomes were collected during the summer of 2015 and sequenced. Phylogenetic analyses were based on sequence data for the nuc-LSU-rDNA (LSU) and ATPase subunit 6 (ATP6) regions. The results showed that I. rosea and I. galericulata are phylogenetically related. They are also clearly distinguished from other members of Phallales such as Phallus spp. and Dictyophora spp., and so our new data supports the raising of Itajahya to the generic level.
