Abstract: Wild coral fungi belonging to the genus Ramaria are consumed as a food by peasants in Mexico Several specimens tentatively identified as Ramaria are being characterized at the classical and molecular levels, and preliminary results are presented Carbohydrate analysis of R flavobnmnescens indicates that glucose (GIc) is the main cell wall component, followed by galactose (Gal) and mannose (Man) The basidiospores of this species show two main wall layers by transmission electron microscopy, a large lipid droplet and an extracellular matrix PCR amplification analysis of an internal 16S mitochondrial subunit in several specimens show a 20 kb band in R flavobrunnescens, and a 500 bp band in Ramaria spp (specimen R2) and R fennica (specimen R12) Amplification of the IGSl hypervanable region at the ribosomal genes unit (rDNA) gives a polymorphic pattern in the specimens of Ramaria analysed The correlation of morphological and microscopical data, as well as the IGSl amplification pattern, suggests that Ramaria spp (specimen R8) is different from the other specimens studied.
