Myxomycetes appearing in moist chamber cultures on four different types of dead leaves

Abstract

Goad AE,Stephenson SL 2013 -Myxomycetes appearing in moist chamber cultures on four different types of dead leaves.Mycosphere 4(4), 707-712, Doi 10.5943/mycosphere/4/4/7 AbstractOne of the microhabitats available for myxomycetes in temperate forests is represented by the layer of dead plant material that accumulates on the forest floor. This layer, referred to as the litter layer, consists mostly of dead leaves from the trees that make up the forest canopy. In the present study, leaves from four different species of trees (dogwood, red maple, sycamore and white oak) were collected from the upper portion of the litter layer and used to prepare moist chamber cultures to determine whether each type of leaf displayed evidence of supporting a different ecological assemblage of myxomycetes. Leaves were collected on two occasions, January 2012 and January 2013. Forty moist chamber cultures were prepared for each type of leaf on each date, for a total of 320 cultures for the entire study. Most of these (60.6%) yielded some evidence (either sporocarps or plasmodia) of myxomycetes, and 21 species in nine genera were represented among the 244 records of sporocarps recorded from the cultures. Members of the order Physarales made up 59% of all records, with members of the orders Stemonitales (30%) and Trichiales (11%) relatively less important. Major differences existed in the productivity of the two sets of leaf samples (with 2013 appreciably more productive than 2012) and for particular types of leaves (with dogwood characterized by an overall positive value of 92.5% and sycamore with an overall positive value of only 11.5%). Remarkably, the set of samples of sycamore leaves collected in 2013 yielded no positive cultures.

Ecological assemblages of corticulous myxomycetes in forest communities of the North-East Ukraine

“…In total, we collected 358 samples of the bark of 16 tree species (Acer campestre L., A. platanoides L., Betula pendula L., B. pubescens Ehrh., Crataegus sp., Fraxinus excelsior L., Gleditsia triacanthos L., Malus sylvestris L., Pinus sylvestris L., Prunus armeniaca L., P. domestica L., Populus tremula L., Quercus robur L., Robinia pseudoacacia L., Tilia cordata L., Ulmus sp.). The myxomycete fructifications were obtained using the moist chamber technique, which involves keeping the bark samples on moist filter paper in Petri dishes (Goad & Stephenson, 2013;Schnittler et al, 2015). Incubation in humid conditions leads to germination of the spores of myxomycetes and the following development of their fruiting bodies.…”

Myxomycetes associated with a residential ecosystem

“…The records of myxomycetes reported were based on specimens collected directly in the field or appearing in moist chamber cultures. These other studies include Eliasson et al (1988), Goad and Stephenson (2013), Massingill and Stephenson (2013), Fischer and Stephenson (2014), Clayton et al (2014), dela Cruz et al (2014), andStephenson et al (2020). As result, the myxomycetes of Arkansas are relatively well known.…”
