Mosses and the beginning of plant succession on the Walker Glacier, southeastern Alaska

[摘要] Three mosses, a basidiomycete fungus (perhaps Mycena) and seedlings (perhaps Epilobium) are reported as growing on dead ice of a glacier in southeastern Alaska. By far the most abundant species was Racomitrium fasciculare which appears to begin directly on the ice, and trapping mineral particles, grows up mostly into irregularly shaped patches but it can become more or less hemispheroidal on pedestals of ice. Many of the tufts of which there are thousands, develop to face southeast on tiny mounds of ice and protect the ice to the northwest.
