Discomycetes richness from a cloud forests in Venezuela.

A discomycete diversity study was conducted in a cloud forest of El Avila National Park in Venezuela. A systematic collecting scheme based in transects was used as sampling method. Two plots were selected, and along 60 m long transects, twelve 1 x 1 m subplots were established on either side of each of the transect lines at 5 m intervals. Both sites were visited twice during the winter season for a total of 24 samples for each site. For each plot 24 and 27 species were identified respectively. Jaccard Species Similarity Coefficient between plots was 27%. Different estimators used to calculate species richness show that just between 40-60% of the species were observed during this study. Rarefaction curves indicate that the minimum number of subplots needed to obtain 80% of the actual species at each site is about 50, which means that at least another two samplings would have been needed. Discomycete species were distributed in the following orders: 27 Helotiales, 6 Rhytismatales, 4 Pezizales, 3 Orbiliales, 2 Lecanorales, 1 Ostropales for a total of 45 species. This work adds 9 new records to Venezuela and 8 possible new taxa.
