Secotioid fungi are an intermediate growth form between mushroom-like hymenomycetes and closed bag-shaped gasteromycetes, where an evolutionary process of gasteromycetation has started but not run to completion. Secotioid fungi may or may not have opening caps, but in any case they often lack the vertical geotropic orientation of the hymenophore needed to allow the spores to be dispersed by wind, and the basidiospores are not forcibly discharged or otherwise prevented from being dispersed (e.g. gills completely inclosed and never exposed as in the secotioid form of Lentinus tigrinus)—note—some mycologists do not consider a species to be secotioid unless it has lost ballistospory. Explanation of secotioid development and gasteromycetation Historically agarics and boletes (which bear their spores on a hymenium of gills or tubes respectively) were classified quite separately from the gasteroid fungi, such as pu
Los hongos secotioides son una forma intermedia de crecimiento entre himenomicetas similares a hongos y gasteromicetas en forma de bolsa cerrada, donde se ha iniciado un proceso evolutivo de gasteromicetación pero no se ha completado. Los hongos secotioides pueden o no tener capas abiertas, pero en cualquier caso a menudo carecen de la orientación geotrópica vertical del himenóforo necesario para permitir que las esporas sean dispersadas por el viento, y las basidiosporas no se descargan forzadamente ni de otro modo se impiden de ser dispersas (por ejemplo, giles completamente incluidos y nunca expuestos como en la forma secotioide de Lentinus tigrinus) - algunos micólogos no consideran que una especie sea secotiada a menos que haya perdido ballistospory.
