Gloeomyces is a genus of fungi within the family of layer fungus relatives (Stereaceae). The genus differs from the other genera of the Gloeocystidiellum complex by the occurrence of connective hyphae . In addition, all known species of the genus simply have septate hyphae without buckles , udder-shaped basidia and smooth, amyloid basidiospores . The type species of the genus is Gloeomyces graminicola Sheng-H. Wu .

features

The resupinate fruiting bodies are more or less membranous. The hyphae system is dimitic and consists of generative hyphae and connective hyphae. The generative hyphae are simply septate. The connective hyphae, which are relatively sparsely distributed in the deep subiculum , are thick-walled and yellowish to brownish in color. However, their occurrence does not mean that the fruit bodies are leathery or tough in any way. In addition to the 4-spore, udder-shaped (utriform) basidia , numerous gloeocystids occur. They are moniliform and weakly sulfoaldehyde positive. The smooth, amyloid and acyanophilic basidiospores are ellipsoidal.

Ecology and diffusion

While Gloeomyces graminicola and Gloeomyces ginnsii were predominantly isolated from sweet grasses, Gloeomyces moniliformis is found on hardwood. The three species were all found in Taiwan, Gloeomyces moniliformis is also found in Japan.

Systematics

etymology

The generic name is derived from the ancient Greek word "gloios" (= "sticky substance") and "-myces" (= "mushroom") and refers to the occurrence of gloeocystids.

The genus differs from other genera of the Gloeocystidiellum complex by its dimitic hyphae system. In addition to the generative hyphae, branched, thick-walled hyphae can be found in the subhymenium, which are strongly reminiscent of connective hyphae. Otherwise the types of the genus are quite uniform. They simply have septate generative hyphae, utriform basidia, and smooth basidiospores. The genus has similar properties as the genera Vesiculomyces and Gloiothele . Therefore, N. Maekawa, the first author of Gloeomyces moniliformis, placed the white rot fungus in the genus Vesiculomyces in 1994 . However, the genera differ in that Gloeomyces , when cultivated , forms hyphae that have single or multiple nodular hyphae, while the hyphae of Vesiculomyces are always buckled.

Gloeomyces graminicola forms with the Aleurodiscus cerussatus / A. dextrinoideocerussatus group a community of descent . All three species have smooth, thin-walled, ellipsoidal spores and numerous sulfoaldehyde-positive and more or less moniliform (pearl-like) gloeocystids. In contrast to Aleurodiscus cerussatus and A. dextrinoideocerussatus , acanthohyphidia are absent in Gloeomyces graminicola , and it has buckleless hyphae, while these are nodularly septate in the other two species.

species

The genus contains three species worldwide. So far only Gloeomyces graminicola has been investigated in terms of molecular biology.
