 Note: It is very common in the forests of Taiwan from 300 m to 2,275 m altitude. According to the studies on the biodiversity of inoperculate discomycetes in Fushan Botanical Garden (abbreviated to F. B. G.) from Jan. 1994 to Dec. 1996, it was found that this species is a dominant species except from Jan. to Mar. in F. B. G. This species is most abundant during Aug. to Oct. and more than 600 samples had been found in these months. The meteorological data from the area of F. B. G. had been surveyed and it had shown that this species is abundant at the average temperture among 20-23℃ and relative humidities at the range of 90-95%. In general, the apothecia appear in spring, fruit abundantly in summer then gradually disintegrate when weather turning dry and cold. Taiwanese specimens were collected from wood substrate, such as branches, twigs and roots of broad-leaved trees.
