Abstract
AbstractBoletus alutaceus Morgan an ectomycorrhizal species was extensively studied from an ecologically fragmented microhabitt colonized by its' host plant Ficus benghalensis L. in the Goa University campus, Taleigao, Goa, India. Qualitatively the fruiting cycles were monitored for three years and thereafter detail ecological and morphological investigations were carried out in May and November 2004. A bimodal temporal fruting pattern emerged which may have significant ecological, phenological and biochemical role in EM dynamics.
Highlights
Ectomycorrhizal (EM) fungi are in three vast groups including Zygomycetes (Endogonales), Ascomycetes and Basidiomycetes
B. alutaceus basidiospores which escape grazing, ingestion and dispersal may germinate within the rhizosphere of the host to produce new vegetative mycelia
Flowering and fruiting of F. benghalensis may depend on the biochemical vigour of its’ EM partner
Summary
Year-long study of F.benghalensis habitat to identify emergence of the EM fruitbodies on the basis of previous site records. Collection, spatial locational mapping, photo documentation and morphometric measurements of the specimens. Comparison of the harvest in different seasons Identification of any ecologically significant phenomena and phenological events associated with fructifications. The habitat was mapped and the records of ambient temperature, humidity and soil temp. The specimens were located, counted, inscribed/labelled ‘in situ’, photographed in random quadrats and plucked. Identification was confirmed with type specimens collected in the past and with respect to standard keys for Indian boletaceae (Lakhanpal, 1996). Measurements of pileal diameter, colour, thickness, shape, stipe length and thickness were made. Statistical comparison of the data was done for collections made six months apart
