Twenty nine phototrophic taxa are reported from a small volcanic cave. These included five cyanobacteria, two of which are heterocystous nitrogen-fixers, and nine diatoms, several of which have previously been reported from caves. Of the five lichen taxa, two are foliose nitrogen-fixers, suggesting that combined nitrogen was in short supply. The aerophytic flora show similarities with communities from limestone caves suggesting that low light and high humidity are of overriding importance for some taxa.
