Caloscypha fulgens (Ascomycetidae, Pezizales): the perfect state of the conifer seed pathogen Geniculodendron pyriforme (Deuteromycotina, Hyphomycetes)

Abstract

Results of comparative cultural, conidiophore and conidia morphology, growth–temperature, and pathogenicity studies proved that Geniculodendron pyriforme Salt is the imperfect state of Caloscypha fulgens (Pers.) Boudier. The results are discussed in relation to the etiology and ecology of the disease of conifer seeds caused by the fungus.

Bark beetles, fuels, fires and implications for forest management in the Intermountain West

“…For example, Jenkins et al (1998) determined that 200-400 years are needed for a spruce-fir climax forest to develop in northern Utah, which generally agrees with other fire history studies in the northern Rockies (Arno, 1980). Environments for tree establishment within the spruce-fir zone are marginal (Daniel and Schmidt, 1972;Paden et al, 1978;Knapp and Smith, 1982;Alexander, 1987). Survival is especially low on burned sites where extreme heat, frost, and browsing kill unprotected Engelmann spruce seedlings.…”

“…The majority of advanced regeneration, particularly on dry sites at lower elevations is subalpine fir. The relatively small proportion of advanced spruce regeneration in the understory of mature stands can be attributed to the inability of spruce seedlings to establish in heavy duff layers and several species of fungi that specifically infect spruce seeds (Daniel and Schmidt, 1972;Paden et al, 1978;Knapp and Smith, 1982;Alexander, 1987;Aplet et al, 1988). Consequently, subalpine-fir typically dominates stands for about 200 years until trees succumb to the effects of disease (Veblen, 1986a,b;Aplet et al, 1988).…”

2 Pezizomycotina: Pezizomycetes, Orbiliomycetes

“…Pithya species may cause dieback on conifers. Caloscypha fulgens is implicated as a seed pathogen of conifers (Paden et al 1978;Salt 1974). Urnula craterium has been implicated as the causal agent of strumella canker in oak (Davidson 1950).…”
