of the isolation and culture of lignicolous marine fungi 

 (0.1% glucose; 0.01'r yeast extract; 1.8% agar in aged 

 seawater adjusted to approximately 20% o ; 0.03': < U.S.P. 

 streptomycin sulfate). White birch applicator sticks, 

 balsa strips, filter paper, or toweling paper added to the 

 culture tubes serve as an additional cellulosic substrate. 

 Methods of preparing specimens for embedding, serial 

 sectioning, and differential staining are outlined 

 elsewhere (Cavaliere 1966, 1973). 



Several additional works covering various aspects of 

 the biology and taxonomy of marine Ascomycetes may be 

 useful to the student (Barghoorn and Linder 1944; John- 

 son and Sparrow 1961; Cavaliere and Johnson 1966; 

 Kohlmeyer and Kohlmeyer 1971). 



GLOSSARY 



The use of mycological terminology has been reduced 

 to a minimum. Several terms are defined as well as il- 

 lustrated. More complete definitions are found in Snell 

 and Dick (1957) and Ainsworth and Bisby (1971). 



Acuminate Gradually narrowing to a point. 



Amerospore One-celled spore; spore without partitions. 



Amorphous Without definite shape or structure. 



Anastomose To form a network of interconnecting hy- 

 phae. 



Antepenultimate Refers to the third to the last cell in 

 any row of cells. 



Apiculate Having one to many sharp points or denticles. 



Appendage A process of any kind; a structure which ad- 

 heres. 



Ascocarp A fructification in Ascomycetes bearing asci 

 and ascospores (see Figs. 1-3). 



Ascospore A spore, typical of the sexual stage or cycle 

 in Ascomycetes, borne in an ascus. 



Ascus A reproductive cell in Ascomycetes; a structure, 

 within which are produced, by meiosis, normally 4-8 

 haploid spores (see Figs. 6, 7). 



Attenuate Gradually narrowing or thinning. 



Awl-shaped Gradually tapering from the base to a 

 sharp, flexible or semirigid point. 



Bacilliform Refers to spores which are rod-shaped (see 

 Fig. 24). 



Basidiocarp A fructification in Basidiomycetes produc- 

 ing basidia and basidiospores. 



Basidiospore A sexual spore; produced by meiosis and 

 borne on a basidium. 



Basidium A cell within which nuclei first undergo re- 

 duction division then pass onto extensions externally 

 forming basidiospores. 



Bitunicate Refers to asci having two walls; double- 

 layered (see Fig. 7). 

 Biturbinate Refers to 2-celled spores having both ends 



conical and slightly curved. 

 Catenulate Attached in chains. 

 Clauate Club-shaped or thickened at the apex (see Fig. 



13). 

 Cleistothecium A more or less spherical covering en- 



closing asci; a fruiting structure in the Ascomycetes 

 (Plectomycetes) produced as a result of sexual repro- 

 duction and opening at maturity by a rupture (see Fig. 

 1). 



Concolorous Refers to the pigmentation being the same 

 color throughout. 



Conidiophore A specialized hypha or cell bearing coni- 

 dia. 



Conidium Spores produced by the Deuteromycetes; a 

 spore borne on or in a specialized hypha termed a coni- 

 diophore; asexually produced spores. 



Deciduous Short-lived; falling away; not persistent. 



Deliquescent Dissolving or liquifying. 



Denticulate Having small teeth. 



Dictyospore A spore with many transverse and longi- 

 tudinal septations; a muriform spore (see Fig. 23). 



Didymospore Two-celled spores; spores with a single 

 partition. 



Echinulate With minute spines. 



Ellipsoidal Refers to spores having the shape of an el- 

 lipse; generally rounded at both ends and having curved 

 sides (see Fig. 19). 



Elongate Longer than broad, having parallel sides (see 

 Fig. 18). 



Endogenous Borne or developing within. 



Epispore The outer layer of the spore wall. 



Erumpent Breaking through the surface of the sub- 

 strate; refers to the position of the fruiting body with 

 relationship to the substrate. 



Eucarpic Refers to a condition in which only part of the 

 somatic thallus is converted in the formation of fructi- 

 fications. 



Filiform Refers to spores which are slender and thread- 

 like (see Fig. 22). 



Fuscous Drab, gray or smokey in color. 



Fusiform Spindle-shaped or tapering at both ends (see 

 Fig. 12). 



Fusoid Somewhat fusiform. 



Globose Refers to spores which are spherical (see Fig. 

 8). 



Guttule Oily, spherical globule. 



Helicospore A spiral or helicoid spore (see Fig. 20). 



Holocarpic Refers to a condition in which the entire 

 somatic thallus is converted into a fructification. 



Hyaline Transparent or translucent, colorless. 



Inequilateral Having unequal sides. 



Innate Occurring below the surface of the substrate. 

 Refers to the position of the fruiting body with rela- 

 tionship to the substrate. 



Intercalary Borne or developed between the base and 

 apex of hyphae. 



Involuted Rolled or enrolled. 



Lenticular Refers to spores shaped like a double convex 

 lens (see Fig. 11). 



Muriform Refers to spores having both transverse and 

 longitudinal septations (see Fig. 23). 



Oblong Longer than broad with approximately parallel 



sides (see Fig. 15). 

 Obpyriform Reverse pear-shaped (see Fig. 17). 

 Obtuse Blunt or rounded, not pointed.
