Hemitrichia clavata

Abstract

Diagnostic features. Hemitrichia clavata is sometimes difficult to distinguish from H. calyculata (Speg.) M.L. Farr, which is much more common. The deep cup which gradually widens from the stout stalk, the rough capillitium, white plasmodium and warty, rather than spiny, reticulation of spores separate H. clavata from H. calyculata. Very generally, H. clavata tends to occur in mountainous or cold-temperate regions during autumn and winter, whereas H. calyculata may occur more in warm-temperate or tropical climates over summer and autumn.
