Taxonomy

edit

The type specimen was collected from Point Lookout (New England), at an altitude of 1,500 m (4,900 ft). Here it was found growing in scrub on twigs of Banksia integrifolia subsp. compar. The lichen is only known to occur in this area, where it grows as an epiphyte on twigs, branches, and trunks in wet scrub and forest dominated by sclerophyll. It also occurs in rainforest dominated by Antarctic beech (Nothofagus moorei). The specific epithet honours Australian botanist John Beaumont Williams, "who co-collected some of the material on which the description is based and had an intimate knowledge of the botany of the New England region of northern New South Wales".[1]

Description

edit

The main characteristics of Menegazzia williamsii are an inflated and fragile thallus lacking soredia; the presence of the secondary chemical stictic acid and the lack of isopigmentosin; asci with two spores; and a scattered (inspersed) epihymenium. Other Menegazzia species with which it shares some characteristics include M. elongata, M. platytrema, and M. pertransita.[1]
