| The cystidia of the genus Subulicystidium have been studied with the scanning electron microscope. Their ornamentation consists of two rows of ribbon-shaped structures, arranged crosswise to the main axis of the cystidia. The free ends of these structures are double-refractive and have formerly been described as ‘four rows of short crystals’. A key to the accepted three species is given; one new combination is proposed. |

| One of the fungi with very variable basidia is Corticium udicola Bourd., showing in the same basidiocarp all stages between sessile clavate basidia, podo- and pleurobasidia. Interesting features are the large sterigmata — not often found in species of Corticiaceae — and the amyloid spores. For this species Hauerslev (1974) created the monotypic genus Melzericium, based on his own collection from Sweden. A stay at the Museum National d’Histoire Naturelle in Paris gave the opportunity to study all the specimens of Corticium udicola. Soon it was evident that the collections contained two different but closely related species, one of which agreed very well with the descriptions given by Bourdot (1910) and Bourdot & Galzin (1928). The second species is... |

| Several species of the genus Athelia show a close relationship with either free-living algae or algae within lichens. Although most taxa of Athelia live as saprophytes, a growing number of species is known to form basidiolichens and as such grow constantly together with algae which do not seem to be much damaged. Apart from the species which are known as parasites of algae and lichens, there are three species which live symbiotically with filamentous Cyanophyceae (Algae), viz. Athelia andina Jülich, A. epiphylla Pers., and A. phycophila Jülich. Athelia epiphylla occurs mostly as a saprophyte on a variety of substrates, whereas the other two species are only known as basidiolichens. Athelia andina and A. phycophila are devoid of clamps at every septum of... |

| After a study of type specimens of the Corticiaceae two species have to be transferred to other genera: i) Athelia teutoburgensis (Brinkm.) Jülich, comb. nov. (basionym: Corticium teutoburgense Brinkm.), which replaced Corticium flavescens Bres., and ii) Ceraceomyces borealis (Romell) Jülich, comb. nov. In Athelia teutoburgensis [syn.: Athelia macrospora (Bourd. & G.) M. P. Christ.] the spores show normally one nucleus, in contrast to the spores of Corticium terrestre (Kniep) Kniep with always two nuclei. Athelia subovata, spec. nov. is described from Sweden. Byssocorticium neomexicanum Gilb, et Budd. has been studied. |

| Among the minute clavarioid fungi, my attention was drawn to Ceratellopsis and the tiny Pterula gracilis of which the last one has been collected several times in the Netherlands. Pterula gracilis is a species not always easily recognized as a Pterula and more often identified as a Typhula, although the hyphae are too thick-walled for that genus. Typhula, inclusive of Cnazonaria, Pistillaria and several other closely related genera, is characterized by a monomitic hyphal system, and so is the genus Ceratellopsis, which differs from Typhula mainly in the distinct sterile, apex of the basidiocarp and the absence of sclerotia. |

| A collection of Aphyllophorales from Australia and Tasmania has been studied. Fifteen species have been identified and the following new taxa are described: Amaurohydnum flavidum gen. et spec. nov., Amauromyces pallidus gen. et spec. nov., Hyphoderma cinnamomeum, Lindtneria pellicularis, Resinicium luteum spp. nov. The new combination Radulodon calcareus (Cooke & Massee) is proposed. |

| The genus Leucogyrophana Pouz. has been placed in the Coniophoraceae by some authors on account of the cyanophilous spores, by which character the Coniophoraceae are said to differ from the Corticiaceae. Contrary to this opinion it is shown that not all the species of the Coniophoraceae exhibit cyanophily. Moreover the same spore reaction has been observed in a rather large number of species of the Corticiaceae. This means that ‘cyanophily’ is not a conclusive key character for a distinction between the two families mentioned. It is proposed to maintain Leucogyrophana in the Corticiaceae. A key to the accepted species of this genus is presented. |

| Crustomyces The following new taxa are proposed: Australohydnum gen. nov. (based on Hydnum griseo-fuscescens Reich.), Ceraceohydnum brunneum gen. et spec. nov. gen. nov. (based on Odontia subabrupta Bourd. & Galz.), Megalocystidium gen. nov. (based on Corticium leucoxanthum Bres.), Phlebiopsis gen. nov. (based on Thelephora gigantea Fr.), and Scotomyces gen. nov. (based on Corticium fallax). Seven new combinations are proposed. |

| During an excursion of the Dutch Mycological Society to the Bois de Resteigne (prov. Namur, Belgium) in 1977, a curious lignicolous clavate fungus was found growing out of a resupinate basidiocarp. Since the clavate body had the same colour as the resupinate part, a possible relationship between the two parts was supposed but seemed highly improbable since no such large structures connected with a thin resupinate basidiocarp are known up to now. The resupinate part showed a yellowish-brownish colour, stained slightly reddish in a diluted solution of KOH and was easily identified as Trechispora vaga (Fr.) Liberta, owing to its monomitic hyphal system, inflated and clamped hyphae, small four-spored basidia which often develop a lateral, basal outgrowth... |

| In 1899, P. Hennings described a new genus of ‘Thelephoraceae’, viz. Cerocorticium, based on two specimens collected by E. Nyman and M. Fleischer on Java. According to him these specimens represented two different species of his new genus. The descriptions Hennings gave of the genus and the two species are rather poor and incorrect. His diagnosis of the genus runs: ‘Resupinato-effusum, subgelatinosum, sicco ceraceum. Hymenium glabrum, laeve. Basidia conferta, subclavata, 2- sterigmatibus. Sporae ellipsoideae vel ovoideae, hyalinae.’ (p. 138, in reprint p. 40). In a short discussion he declared the genus to be quite different from any Corticium because of the permanently 2-spored basidia and distinct from Michenera because of the absence of paraphyses.... |

| During a study of some Tulasnella species from the Bourdot herbarium (PC), I examined a specimen collected by Galzin in 1909 and identified by Bourdot as Tulasnella vernicosa. Since many species of Tulasnella in dry state are invisible to the naked eye, I had to make sections of several parts of the wood surface, but could not detect the typical Tulasnella basidia with strongly inflated sterigmata. Instead of a Tulasnella, I found some clampless hyphae, strongly urniform basidia with short, subulate sterigmata, and basidiospores of a very unusual shape: they were distinctly forked or two-lobed, with two diverging parts. A study of the literature showed this to be a North American species of Galzinia, viz. G. geminispora Olive. This species seems to be very... |
