Collema Weber ex F.H. Wigg is scarcely scattered throughout South Korea. However, a detailed taxonomic or revisionary study has not been carried out for almost two decades. The present study was based on specimens deposited in the lichen herbarium at Korean Lichen Research Institute, which were identified using recent literature. In this revisionary study, a total of sixteen species of Collema, including five new records, C. furfuraceum var. luzonense, C. pulchellum var. subnigrescens, C. rugosum, C. subconveniens, C. tenax, and one variety C. leptaleum var. leptaleum were documented. Further, detailed descriptions of each species and their morphological, anatomical and chemical characteristics and a key to all known Collema species of South Korea were reported.

Protoplasts of P. cornucopiae were reverted to normal hyphal growth and reversion frequency was $0.04{\sim}19%$. The complete medium stabilized with 0.6 M sucrose was most effective for regeneration of protoplasts. When hypertonic mushroom complete medium not containing agar was overlaid, regeneration frequency of protoplasts was the highest rate among the others of topagar. The protoplast reversion frequency and mycelial growth of P. cornucopiae were increased when various amino acids, nucleic acid components and vitamin compound were added to the hypertonic minimal medium. The relation between sources increasing reversion frequency and sources accelerating mycelial growth was similar in amino acids and nucleic acid components but it was different in vitamins. The protoplast reversion frequency showed the highest rate when all sources were added to the regeneration minimal medium. Microscopically, regeneration patterns of protoplasts showed formation of a bud-like structure, direct germination, yeast-like cell chain of the protoplast, and the production of both direct germ tube and yeast-like cell chain from a protoplast.

Seven species of higher fungi which were collected at Kwangneung, Mt. Hanla, Mt. Chiri, Taeqwanryung, and Yeongdong district, and preserved in the institute from 1975 to 1977, were classified into new korean species. Also, two species of fungi were collected from April to October 1978 and identified at Suweon, Kwangneung, and Mt. Chiri. They were as follows: Hygrophorus pratensis, H. flavescens, H. puniceus, Rhodophyllus rhodopolious Lepiota atrosquamulosa, Leucocoprinus fragilissima Lyophyllum semitale, Russula delica and Xerocomus badius.

An unrecorded Hypoxylon sp. was observed on the bed-log of oak-mushroom (Lentinula edodes) in Korea. The stroma of the fungus was formed on the bed-log (Quercus spp.) damaged by Korean squirrel (Sciurus vulgaris coreae). Perithecia were $200{\sim}400{\mu}m$, and asci containing 8 ascospores were $7{\sim}8{\times}150{\sim}230{\mu}m$ in size. Paraphysis was cylindrical shape, Ascospores were $5{\sim}9{\times}12{\sim}17.5{\mu}m$ in size, pale brown to dark brown, elliptical, and smooth. They have germination cleft and $1{\sim}2$ oil droplets.

Interspecific hybrids of Pleurotus ostreatus and Pleurotus florida were formed by using protoplasts of complementing auxotrophs. The genetic markers were shown to segregate and recombine in the first generation of monosporus isolates from basidiocarp of seven fusion products. The analysis provides proof of heterokaryosis and strong evidence for haploidy of vegetative nuclei, a sexual cycle consisting of nuclear fusion and meiosis. In all the crosses there was no evidence of linkage between the genetic markers. Clamp connections were formed in monosporus mycelia from basidiocarp of fusion products.
