Attraction Toward and Penetration of Polyporus Dryophilus Var. Vulpinus Basidiospores by Hyphae of the Same Species

SUMMARY

Hyphae of P. dryophilus grow toward and penetrate the basidiospores of this same species. Penetration occurred through the pore from which a germ tube would normally arise, except in one of the four isolates in which penetration occurred through the side of the spore. Growth of hyphae toward, and penetration of spores occurred with 15 single spore isolates and with mass cultures from four different isolates in all possible combinations.
