RESUMO -(O gênero Calostoma (Boletales, Agaricomycetidae) em áreas de cerrado e semi-árido no Brasil). O gênero Calostoma está representado no Brasil por duas espécies: C. cinnabarinum Desv., registrada pela primeira vez no Brasil e C. zanchianus (Rick) Baseia & Calonge, que ocorrem nas regiões sul, sudeste e nordeste. São fornecidas descrições, ilustrações e imagens em MEV da ornamentação dos esporos.Palavras-chave: Basidiomycota, Gasteromycetes, neotrópicos, Sclerodermataceae, taxonomia ABSTRACT -(The genus Calostoma (Boletales, Agaricomycetidae) from the Brazilian cerrado and semi-arid areas). The genus Calostoma is represented in Brazil by two species: C. cinnabarinum Desv., reported for the first time in Brazil and C. zanchianus (Rick) Baseia & Calonge. These species occur in the South, Southeast and Northeast regions. Descriptions, illustrations and SEM-images of spore ornamentation are provided.

“…1). This is a feature common to the species of Calostoma with globose, warted spores and is illustrated in several taxa described by Massee (1888). Comparative ultrastructural studies of the spores of the other warted-spored species of Calostoma with convergent teeth are in progress.…”

“…Massee was first described as Mitremyces junghuhnii Schlechtendal & K. Muller in 1844. The type collection was found in December 1842 by Junghuhn during an expedition to collect living specimens (natural products) in the forest of BattaLauder near Tapoilang, Java at an elevation of 200-300 m. Massee (1888) lists additional records from Sumatra and Sikkim (Himalaya). Balfour-Browne (1955) indicates further distributions from southeast Tibet and Bhutan.…”

Fresh specimens of Colostoma junghuhnii (Schl. & Müll.) Massee, collected in Nepal, are described. The ultrastructure of the basidiospore wall is compared with that in the three North American species of Colostoma. The spore wall of C. junghuhnii is ornamented with pyramidal warts; that of C. cinnabarina Desvaux, the type species of the genus, is pitted. The ultrastructure of the spore wall in the two species is similar. The distinctive stoma and other features distinguish C. junghuhnii from the other species of Colostoma but do not warrant recognition as a second genus in the Calostomataceae.

“…The Boletales are mostly ectomycorrhizal with some saprotrophic members, while all core Sclerodermatineae genera -Scleroderma (Godbout and Fortin 1983;Buée et al 2004), Pisolithus (Moyersoen and Beever 2004), Astreus (Danielson 1984), Gyroporus (Agerer 2002) -are considered ectomycorrhizal. Hughey et al (2000) described Calostoma cinnabarinum Corda as a litter decomposer after Miller and Miller (1988), but this assumption is most likely based on previous taxonomic comparisons with the saprotrophic Tulostoma (Burnap 1897) and with Geastrum (Massee 1888), which have been previously described as saprotrophic (Kreisel 1969;Miller and Miller 1988;Sunhede 1989), but more recently described as ectomycorrhizal (Agerer and Beenken 1998). However, Hughey et al (2000) acknowledged that the classification of Calostoma as saprotrophic was probably based on previous taxonomic placement and suggested that the ecological role of this fungus should be further investigated.…”

The ectomycorrhizal status of Calostoma cinnabarinum determined using isotopic, molecular, and morphological methods

Calostoma cinnabarinum Corda belongs to the suborder Sclerodermatineae (Boletales), which includes many well-known ectomycorrhizal basidiomycetes, but the genus Calostoma has been described as saprotrophic. This study combines isotopic, molecular, and morphological techniques to determine the mode of nutrition of C. cinnabarinum. δ13C and δ15N measurements were compared among co-occurring C. cinnabarinum, ectomycorrhizal fungi, saprotrophic fungi, and ectomycorrhizal plants. Isotopic profiles of C. cinnabarinum resembled those of ectomycorrhizal fungi but not those of saprotrophic fungi. For molecular analyses, ectomycorrhizal root tips were extracted from soil cores collected beneath C. cinnabarinum fruit bodies. Nuclear ribosomal internal transcribed spacer (nrITS) sequences were obtained from ectomycorrhizal root tips using fungal-specific primers and screened against C. cinnabarinum nrITS sequences. Ectomycorrhizal root tips had nrITS sequences that matched C. cinnabarinum fruiting bodies. Root tips colonized by C. cinnabarinum were also described morphologically. Several morphological characters were shared between fruiting bodies and ectomycorrhizal root tips of C. cinnabarinum. Results of isotopic, molecular, and morphological analyses indicate that C. cinnabarinum is ectomycorrhizal. Molecular analysis and observations of plant associations suggest that C. cinnabarinum forms ectomycorrhizae with Quercus .
