Phylogenetic Resolution of Morchella, Verpa, and Disciotis [Pezizales: Morchellaceae] Based on Restriction Enzyme Analysis of the 28S Ribosomal RNA Gene

Primer registro de la familia Morchellaceae (Ascomycota: Pezizales) para Colombia

“…Lo que concuerda muy bien con la descripción aquí reportada. Algunos taxónomos han considerado a M. elata sinónimo o parte del complejo de especies o subespecies que comprenden a Morchella angusticeps Peck., y Morchella conica Pers., (Bunyard et al 1995, Wipf et al 1999, por lo que morfológicamente se pueden confundir. Sin embargo, M. elata se diferencia de M. angusticeps porque está ultima presenta ascocarpos menores a 8 cm de alto, con crestas longitudinales gruesas y alvéolos elongados (Calonge et al 2003), himenóforos estrechamente cónicos de color gris oscuro durante todo su desarrollo (Hernández-Salmerón et al 2013), además muestra esporas más pequeñas que M. elata (Weber 1995).…”

A review on research advances, issues, and perspectives of morels

“…Most of them were described from Europe, with only few described in Asia and USA. Due to insufficient microscopic characteristics and high levels of variability in form and color of ascocarps during different developmental stages (Du et al 2014), affected by ecological and climate factors, the species number in Morchella varies from 3 to 50 or more, which has caused confusing use of homonyms and synonyms (Bresinsky et al 1972; Gessner et al 1987; Volk and Leonard 1989; Jung et al 1993; Bunyard et al 1994, 1995; Kanwal et al 2011; Clowez 2012; Kuo et al 2012; Mortimer et al 2012; Richard et al 2014). …”

Phylogeny of the GenusAgaricusInferred from Restriction Analysis of Enzymatically Amplified Ribosomal DNA

“…Differences in geographic origin have been suggested in other cases where more variation was found between geographically isolated populations of a fungal species than between two distinct species (Bunyard et al, 1995(Bunyard et al, , 1994Jung et al, 1993;Yoon et al, 1990). Finally, polymorphisms and DNA heterogeneity implying high intraspecies diversity actually may predate the taxa.…”

“…Anderson and Stasovski (1992) determined the molecular phylogeny of species of Armillaria from the Northern Hemisphere using sequence analysis following polymerase chain reaction (PCR) amplification of the intergenic region between the 26S and the 5S rRNA genes. Other researchers have used RFLP analysis of PCRamplified rDNA to distinguish isolates of the Gaeumannomyces-Phialophora complex of fungi (Ward and Akrofi, 1994), strains of Rhizobium (Laguerre et al, 1994), genotypes of Pleurotus (Bunyard et al, 1996), and species of Morchella (Bunyard et al, 1995(Bunyard et al, , 1994.…”

“…It is also possible that different geographic locations or differences in environmental conditions can result in polymorphic appearances in nature. The possibility of environmental variation has led some authors to utilize DNA analysis (Bunyard et al, 1995(Bunyard et al, , 1994, immunological relationships (Jung et al, 1993), and allelic variation (Yoon et al, 1990) to confirm taxonomic placement based on morphological characters. Zervakis et al (1994) found much of the variability of Pleurotus spp.…”
