| Note： |
Zoospores discharge in Rhizophydium collapsum is through several papillae, and then the sporangial wall collapses and also partially dissolves. This species is different from R. patellarium by the numbers of discharge pores and differs from R. capillaceum in having the sporangial wall collapse and partially dissolve (Barr, 1971). | |||
