Amylofungus is a genus of fungus within the family of cystid bark fungus relatives (Peniophoraceae). The genus is characterized by its amyloid hyphae, as well as the amyloid gloeocystids and basidia . Other important features of the genus are the sac-shaped basidia and the smooth, amyloid basidiospores . The type species of the genus is Amylofungus corrosus (G. Cunn.) Sheng H. Wu

features

The fruiting bodies are resupinate and have a smooth hymenium . The hyphae system is monomitic . The hyphae are buckled and amyloid, which means that they stain blue with iodine reagents. The four-pore basidia are udder-shaped (utriform) and also amyloid. In addition to the basidia, numerous amyloid gloeocystids occur in the hymenium. These are club-shaped to cylindrical and sulfoaldehyde-positive. The smooth and thin-walled basidiospores are more or less spherical.

Ecology and diffusion

The two species in the genus are white rot mushrooms. Amylofungus corrosus was collected in New Zealand near Wellington and Auckland on various debarked hardwoods and the Amylofungus globosporus , which also grows on hardwood, occurs in Japan.

Systematics

Amylofungus is a genus belonging to the polyphyletic Gloeocystidiellum complex. The genus concept, revised by Donk in 1956, summarizes species that have a resupinate fruiting body, a smooth hymenium and a monomitic hyphae. In addition, the representatives of the genus have a Euhymenium , Gloeozystiden and amyloid Basidiosporen. J. Eriksson and L. Ryvarden subdivided Gloeocystidiellum s. l. in seven groups, which were later raised to new genres by other authors.

The type species of the genus Amylofungus was first scientifically described in 1954 by the New Zealand mycologist GH Cunningham as Corticium corrosum . 1985 JA Stalpers put the taxon due to the monomitic hyphae system, the gloeocystids and the amyloid basidiospores in the genus Gloeocystidiellum . Another ten years later, the Swedish mycologist KE Hjortstam transferred the species to the genus Vesiculomyces , a satellite genus of Gloeocystidiellum , because the buckleless hyphae and spore morphology reminded him of Vescilomyces citrinus, the type species of the genus Vescilomyces . The second species of the genus Amylofungus globosporus was placed in the genus Vesiculomyces by the first descriptor N. Maekawa because of its similarity to Vesiculomyces lactescens , before SH Wu placed it in the genus Amylofungus in 1997 .

The two species of the genus have not yet been investigated in terms of molecular biology, so it is not certain whether they really form an independent community of descent or whether they belong to other genera. Due to its morphology, A. corrosum is very similar to Vesiculomyces citrinus and A. globosporus is similar to Gloiothele lactescens and Gloiothele tropicalis . Ginns and GW Freeman mycologists considered the genera Vesiculomyces and Gloiothele to be synonymous and placed Vesiculomyces citrinus , the type species of the genus Vesiculomyces , in the genus Gloiothele . E. and KH Larsson were able to show with their molecular biological investigations that the two genera are related, but independent sister genera.
