Communities of anamorphic fungi on green leaves and leaf litter of native forests of Scutia buxifolia and Celtis tala: Composition, diversity, seasonality and substrate specificity

Abstract

The species that characterized the fungal communities in the leaves of each of the trees were found to be different. The type of substrate had a stronger influence in determining the composition of the fungal community in both types of forests.

Characterization saprobic fungi on leaf litter of two species of trees in the Atlantic Forest, Brazil

“…Some of these compounds may inhibit fungal growth, whereas others require a variety of enzymes for their degradation ( Vorísková and Baldrian, 2013 ). These differences in the components of leaves may contribute to differences in the composition and frequency of fungi that have been consistently identified among plant species in temperate ( Ormeño et al , 2006 ; Allegrucci et al , 2014 ; Pasqualetti etal. ,2014 ) and tropical forests ( Paulus et al , 2003a ; Rambelli et al , 2004 ; Paulus et al , 2006b ; Magalhães et al , 2011 ; Monkay et al , 2013).…”

“… Zhou and Hyde (2001) suggested the term “recurrence” to replace the specific terms and preferences commonly used to describe interactions of saprobic fungi that occur most often in association with a particular plant species compared with other species in the same environment. The reasons for the recurrence of fungi on different hosts may involve foliar structure and chemistry ( Santana et al , 2005 ; Paulus et al , 2006b ) or the initial decomposition of litter by the action of persistent endophytes present in the tissues of living leaves when they subsequently senesce and fall to the ground ( Hyde et al , 2007 ; Promputtha et al , 2010 ; Unterseher et al , 2013 ; Allegrucci et al , 2014 ). Besides the recurrence of fungi harbored by particular plants, abiotic factors such as climate at collection sites and seasonality influence the composition and structure of fungal communities (Polishook et al.…”

“…Besides the recurrence of fungi harbored by particular plants, abiotic factors such as climate at collection sites and seasonality influence the composition and structure of fungal communities (Polishook et al. , 1996; Ormeño et al , 2006 ; Paulus et al , 2006b ; Allegrucci et al , 2014 ).…”

“…Numerous studies demonstrate the recurrence of saprobic fungi on substrates of decomposing plants, and fungi tend to recur at a higher rate according to the host's genus ( Polishook et al , 1996 ; Paulus et al , 2006b ; Kodsueb et al , 2008 ; Cheewangkoon et al , 2009 ; Magalhães et al , 2011 ; Allegrucci et al , 2014 ). For example, Paulus et al (2006b) investigated the community of fungi associated with six plants and found low overlap among species, which may be accounted for by the phylogenetically unrelated families to which the host plants belong.…”

Diversity and Distribution of Microfungi From Dipterocarp Forests in Sarawak, Borneo Island (Malaysia)

“…Four fungal taxa (Black Mycelia sterilia, Oidiodendron sp., white Mycelia sterilia and Graphium penicillioides) were common on all the five plant species studied. Mycelia sterilia (both white and black forms) are known to be generalist fungi found on a wide range of host plants (Allegrucci, Bucsinszky, Arturi, & Cabello, 2015;Kumar, 2013;Sepiah, Roha, & Laman, 2006) while Oidiodendron sp. and Graphium penicillioides have also been isolated from a variety of host plants.…”
