Gliocladium like fungus
Eduard Osieck, 03-04-2020 14:56
Recently this synnamatous hyphomycete (length 0,2-0,4 mm) with yellow gelatinous heads grew on Alnus catkins (moist chamber). The stipe is clearly KOH-positive. The hyaline conidia were ellipsoid, 6-8,5 x 3-3,5 um.
A similar hyphomycete but taller (about 0,5 mm), heads whitish and similar conidia were found on an old basidiocarp of an hydnoid Corticiaceae (cf. Fibrodontia).
Could these concern a Gliocladium or Gliocladium-like species?
Thanks in advance for id help,
Eduard

Re : Gliocladium like fungus
Hola Eduard
Si fuera mio, para empezar a buscar, lo haría por Stilbella.
Encontrarás información si buscas en el siguiente documento:
"A Monograph of Stilbella and some allied Hyphomycetes"

Saludos cordiales

Re : Gliocladium like fungus
Hi Josep
Thank you for your reaction. The publication concerned (Seifert 1985) lists 9 genera with species that show a positive KOH-reaction. Most of these genera, with the exception of Gliocladium, do not match with my collections (e.g. being non-synnematous). Unfortunately, none of the Gliocladium species described in this publication is fitting. The species concerned may have been described as “Gliocladium-like anamorph” (with the name of the teleomorph).
Cheers, Eduard
