California Moss eFlora

Our one species of Hygroamblystegium can almost be recognized by touch. Hygroamblystegium tenax is a small-leaved aquatic and pleurocarpous moss whose very broad costa and stiffly arching stems give it an overall very coarse feel. No other moss combines a regularly branching pattern with spreading narrowly lanceolate leaves whose costa fills perhaps 1/4-1/5 of the leaf base. The very short cells have elliptical lumina mostly about 3:1 and the cell walls are usually rather thick. Hygroamblystegium tenax can be looked for in thin seepages over outcrops throughout much of the hotter and drier portions of the state. It is especially common on overflowing portions of concrete water-troughs.
