INTRODUCTION TO THE STUDY OF FUNGI 



Conceptacle — a superficial cavity open- 

 ^jng outwards within which conidia 

 or- sporules are produced. 



Conidiophore — same as gonidiophore. 



Comidium — same as gonidium or brood- 

 cell. 



Cortina, or curiam — in Hymenomy- 

 cetes, marginal veil, ruptured from 

 the stipe and hanging from the edge 

 of the pileus, or around the stipe in 

 threads. 



Cryptogamia — applied to the lower 

 orders of plants in which there are 

 no conspicuous flowers, as there are 

 in the Phanerogamia. 



Cuticle, or pellicle — the separable outer 

 layer. 



Cyst — a bladder specially applied to the 

 terminal sporangia of Mucors. 



Cystidium — in Hymenomycetes, large 

 projecting cells of the hymenium, 

 extending beyond the basidia' and 

 paraphyses. 



Dichotomy — branching in pairs in a 



forked manner. \ 

 Disc — the hymenium of a discocarp. 

 Discocarp — an open ascocarp in which 



the hymenium is exposed whilst the 



asci mature. 



Elater — in Myxomycetes, a free 

 capillitium thread, mostly spirally 

 marked or warted. 



Endogonidium — gonidium formed with- 

 in a receptacle. 



Endophytal — growing within another 

 plant. 



Endosporium, Endospore — innermost 

 coat of a spore. 



Entomogenous — growing upon or within 

 insects. 



Epiphytal — growing upon another 

 plant. 



Episporium, Epispore — outer coat of 

 spore. 



Excipulum — outer envelope of a disco- 

 carp developed as part of the recep- 

 tacle. 



Facultative parasite — an organism 

 which normally goes through its 

 whole course as a saprophyte, but 

 which may also go through its course 

 either wholly or in part as a parasite. 



Facultative saprophyte — an organism 

 which normally, goes through its 

 whole course as a parasite, but 

 which can vegetate at certain stages 

 as a saprophyte. 



Flagellum — whip-like process of a 

 swarm - spore, a single or solitary 

 long cilium. 



Funiculus — in Nidulariaceae, the cord 

 of hyphae attaching a peridiolum to 

 the inner wall of the peridium. 



Gamete — sexual protoplasmic body, 

 which on conjugation with another 

 gamete gives rise to a, body called a 

 zygote or zygospore. 



Germ-cell — first product of commencing 

 germination of a spore. 



Gleba — chambered spore - producing 

 tissue within a sporophore. As in 

 Gastromycetes. 



Gonidiophore — sporophore bearing a 

 gonidium. 



Gonidium = conidiwm, or brood -cell — 

 propagative cell, produced asexually, 

 separating from the parent and cap- 

 able of direct development into a 

 new individual. 



Gonoplasm — portion of protoplasm ot 

 antheridium in Peronosporeae which 

 passes through fertilisation tube and 

 coalesces with the oosphere. 



Gonosphere — the same as oosphere. 



Gymnocarpous — having the hymenium 

 exposed while the spores are growing. 



Habitat — the place in which a plant 

 grows. 



Haustorium — special branch of fila- 

 mentous mycelium which serves as an 

 organ of adhesion and suction. 



Heteroecious — forms which pass through 

 separate sections of their complete 

 history on different hosts. 



Heterosporous — having spores asexuajly 

 produced, of more than one kind. 



Homosporous, Isosporous — having spores 

 asexually produced, of only one kind. 



Hymenium — spore mother-cells, aggre- 

 gated in a continuous layer upon a 

 sporophore, or that specialised por- 

 tion termed the receptacle. 



Hymenophore — portion of a sporophore 

 which bears a hymenium. 



Hypha, as applied to Fungi — a cylind- 

 rical, thread-like, simple, or branched 

 body, consisting of a tubular mem- 

 brane enclosing protoplasm, growing 

 apically, and often becoming trans- 

 versely septate. 



Hyphal bodies — irregular bodies analo- 

 gous to mycelium in Entomoph- 

 thoraceae. 



Hypotheeium — layer of hyphal tissue 

 immediately beneath a hymenium.
