phycomycetes |
3 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Fungi \Fun"gi\, n. pl (Bot.) A group of thallophytic plants of low organization, destitute of chlorophyll, in which reproduction is mainly accomplished by means of asexual spores, which are produced in a great variety of ways, though sexual reproduction is known to occur in certain {Phycomycetes}, or so-called algal fungi. Note: The Fungi appear to have originated by degeneration from various alg[ae], losing their chlorophyll on assuming a parasitic or saprophytic life. By some they are divided into the subclasses {Phycomycetes}, the lower or algal fungi; the {Mesomycetes}, or intermediate fungi; and the {Mycomycetes}, or the higher fungi; by others into the {Phycomycetes}; the {Ascomycetes}, or sac-spore fungi; and the {Basidiomycetes}, or basidial-spore fungi. From Webster's Revised Unabridged Dictionary (1913) [web1913]: Phycomycetes \Phy`co*my*ce"tes\, n. pl [NL.; Gr ? seaweed + mycetes.] (Bot.) A large important class of parasitic or saprophytic fungi, the algal or algalike fungi. The plant body ranges from an undifferentiated mass of protoplasm to a well-developed and much-branched mycelium. Reproduction is mainly sexual, by the formation of conidia or sporangia; but the group shows every form of transition from this method through simple conjugation to perfect sexual reproduction by egg and sperm in the higher forms. -- {Phy`co*my*ce"tous}, a. From WordNet r 1.6 [wn]: Phycomycetes n : a large and probably unnatural group of fungi and funguslike organisms comprising the Mastigomycota (including the Oomycetes) and Zygomycota subdivisions of the division Eumycota; a category not used in all systems [syn: {Phycomycetes}, {Phycomycetes group}]
