(mini pellia), Monosolenium tenerum (pellia), Heteroscyphus zollingeri (rose moss), Plagiochilaceae sp. cameroon (cameroon moss). He touched briefly on a few ferns, their life cycle and a few gametophyte ferns used in aquariums, Loxogramme sp. (wave moss), Lomariopsis cf. lineata (susswassertang).

Lastly Tim spoke on mosses, their life cycle, anatomy, the different types and characteristics to identify such as structure and small scale characteristics seen with the aid of a microscope.

He spoke and had slides on the specific characteristics of many species of moss. The different mosses he showed us are Taxiphyllum barbieri (java moss), T. sp. peacock (peacock moss), T. sp.

As if that wasn’t enough he also talked¬†briefly about a few ornamental algae such as redmoss.
