Calvatia nodulata, a New Gasteroid Fungus from Brazilian Semiarid Region

Abstract

Studies carried out in tropical rain forest enclaves in semiarid region of Brazil revealed a new species ofCalvatia. The basidiomata were collected during the rainy season of 2009 and 2012 in two states of Northeast Brazil. Macroscopic and microscopic analyses were based on dried basidiomata with the aid of light microscope and scanning electron microscope.Calvatia nodulatais recognized by its pyriform to turbinate basidiomata, exoperidium granulose to pilose and not persistent, subgleba becoming hollow at maturity, nodulose capillitium, and punctate basidiospores (3–5 μm). Detailed description, taxonomic comments, and illustrations with photographs and drawings are provided.

Revision of species previously reported from Brazil under Morganella

“…According to Agerer (2002), the rhizomorphs of lycoperdaceous fungi are composed of two kinds of hyphae: the thinner outer part has hyphae that are reagent; and the other thicker inner (vessel-like) hyphae are septate or with dissolving septa, hyaline in 5% KOH and weakly dextrinoid with characteristic dissolving septa. All specimens included in this study of subgenera Arenicola and Morganella, have the same rhizomorph features described in Agerer (2002) for lycoperdaceous fungi; and, similar to those described for Calvatia nodulata Alfredo & Baseia in Alfredo et al (2014b). However, in M. rimosa the rhizomoprhs are formed by one kind of hypha, septate, with clamp connections, hyaline, and with the occurrence of oleoacanthocystidia; these features are similar to those in the members of the gomphoid-phalloid clade described in Agerer (2006).…”

Diversity and Distribution of Calvatia Species in India: A New Record from Central India

“…Identification of fungi have been done with the help of published literature (Alfredo et al, 2014;Bisht et al, 2006;Chakraborty et al, 2012;Dorjey et al, 2016;Gogoi and Prakash, 2015;Gupta et al, 1974;Khare, 1976;Syed Abrar et al, 2008;Thind and Thind, 1982;Zeller et al, 1964).…”

Second world record for two Calvatia species (Agaricaceae: Basidiomycota)

“…Currently, around 47 species are accepted for the genus (Kirk et al, 2008;Suarez et al, 2009;Alves and Cortez, 2013;Rebriev, 2013;Alfredo et al, 2014;Crous et al, 2018;Gunasekaran et al, 2018;Crous et al, 2019), where 13 of them occur in Brazil, specifically in the North, Northeast, South and Southeast regions, with most reports for the Atlantic Forest. The Central-Western region of Brazil has no record of the genus.…”
