An electron microscope study has been done on the structure of microconidia and stroma of Sclerotinia sclerotiorum. The microconidia showed the usual cell organelles already described for other species of this genus, e.g. a large nucleus and large lipid body, a few mitochondria and sparse endoplasmic reticulum. The stromatal ultrastructure presented hyphae(More)
Most of the hyphae forming the medulla of the stroma of the brown rot fungi are 4–7 μ in diameter and contain food reserves in large vacuoles and lipid bodies. Some stromatal hyphae have very thick walls and perform a protective function. Smaller hyphae (1–2 μ in diameter) form a network through the medulla and their structure suggests that they initiate(More)
Tomentella bombycina andT. fuscoferruginosa were examined by routine techniques of light and electron microscopy. Special attention was paid to the ultrastructure and inter-relationships of the generative subicular hyphae and subhymenial hyphae. The cell wall consisted of three layers in the generative subicular hyphae and only one layer in the subhymenial(More)
Phallus glutinolens was described from Brazil by Möller in 1895. A new collection of P. glutinolens from the Brazilian Atlantic Forest revealed that Möller’s original description was based on young specimens. New information on morphology is provided for P. glutinolens, and an emendation of the species circumscription is presented. This article also(More)

An examination was made of the ultrastructure of haustoria or intracellular hyphae in four fungi: an obligate parasite (Puccinia hordei), a facultative parasite (Exobasidium japonicum) and two facultative saprophytes (Phytophthora palmivora and Sclerotinia fructigena). P. hordei haustoria showed the typical ultrastructure and host-parasite interface of most(More)
Calvatia sporocristata, Gasteromycetes, is described and illustrated as a new species. Its taxonomic characters are discussed and compared with other closely related species of the genus. Few studies have been carried out on tropical Gasteromycetes. The new species here proposed has, as the main features: exoperidium corky, smooth, one-layered,(More)
A new species of Calvatia from Manaus in Amazonas State, Brazil, is proposed, which is very close to Calvatia sporocristata, recently described from Costa Rica. The two species have been compared macroscopically and examined using light and scanning electron microscopy. The proposed new species, C. oblongispora, possesses a distinctly two-layered(More)
