In both genera, the sporangiophore, guided by light, elongates until the sporangium is brought into contact with a solid surface.
42.
It usually has 32 spores per sporangium, but many with only 16 have been observed, produced from eight 2n mother cells.
43.
Megagametophytes and microgametophytes protruding through sporangium wall; megagametophytes floating on water surface with archegonia directed downward; microgametophytes remaining fixed to sporangium wall.

45.
The L3 larvae of " D . viviparus " invade the inside of these fungi, and wait in the fungal sporangium.
46.
The sporophyte in mosses and liverworts consists of an unbranched stalk ( a seta ) bearing a single sporangium or spore-producing capsule.
47.
The metabolite also inhibits sporangium and zoospore germination of both " P . infestans " and " Phytophthora capsici ".
48.
The epothilones, derived from the myxobacterium " Sporangium cellulosum ", represent a new, recently approved class of cancer drugs.
49.
The presence of simple, stiff hairs on the sporangium is shared with " Oreogrammitis " and " Radiogrammitis ".
50.
When the thallus is fully grown, the sporangium releases numerous, unwalled, uninucleate-zoospores, each bearing a single posteriorly directed flagellum.
