Mat temperatures, moisture concentrations and microscopy data on fungal structures in the tissues of the leafy liverwort Cephaloziella varians exposed to warming for 10 years on Rothera Point

Field measurements collected from a open top chamber (OTC) warming experiment on Rothera Point, Adelaide Island. Data consist of (i) the percentage frequencies of fungal structures recorded in the tissues of the leafy liverwort Cephaloziella varians sampled from five control plots and five plots warmed with OTCs on six occasions between 16 February 2007 and 21 March 2017, (ii) temperatures of C. varians mat measured every 3 h between 17 February 2010 and 23 February 2011 in four control plots and four OTCs and (iii) moisture concentrations of C. varians mat measured on 11 January, 31 January, 14 February and 28 February 2014 in five control plots and five OTCs.
